Arizona vs Nevada: Local Ordinance Comparison (2026)

ADU Rules

Arizona's HB 2720 (2024), codified at A.R.S. 9-461.18, requires municipalities over 75,000 population to permit accessory dwelling units on single-family lots, limiting restrictive zoning, owner-occupancy, and parking mandates. HB 2928 (2025) extends an ADU mandate to counties.

Beekeeping

Arizona requires every beekeeper to register apiaries with the State Department of Agriculture, regardless of city rules, and follows uniform statewide pest and disease management standards.

Nevada law makes it unlawful to keep bees in anything other than movable-frame hives, so inspectors can open colonies to check for disease. The State Department of Agriculture enforces Chapter 552 and can condemn and destroy non-conforming hives.

Breed Restrictions

Nevada law prohibits any local government from adopting or enforcing ordinances that declare a specific breed of dog inherently dangerous or vicious. Cities and counties cannot ban breeds like pit bulls, but may regulate dogs based on individual behavior.

Dog Leash Laws

Arizona requires all dogs to be on a leash no longer than six feet whenever off the owner's property, and enforces statewide rabies licensing for dogs over three months old.

Wildlife Feeding

Arizona makes it unlawful to intentionally feed or attract wildlife, except birds and tree squirrels, in Maricopa, Pima, and Pinal counties under A.R.S. 13-2927. The offense is a petty offense targeting coyotes, javelina, and similar animals.

Nevada Department of Wildlife prohibits feeding big game mammals like deer, elk, bighorn sheep, mountain goats, antelope, and mountain lions. NAC 503.145 makes intentional feeding unlawful statewide to prevent habituation, disease spread, and human-wildlife conflicts.

Tobacco Retail License

Nevada requires vapor and other tobacco product retailers to hold a Tobacco Retail Dealer's License from the Department of Taxation, verify buyers are 21, and remit the 30 percent other-tobacco-products wholesale tax on vapor products.

Recreational Drones

Nevada regulates drones by statute: NRS 493.103 lets a property owner sue for trespass when a drone flies below 250 feet over their land, and NRS 493.109 bars flying within 500 feet horizontally or 250 feet vertically of a critical facility, or within 5 miles of an airport, without consent.

Minimum Wage Preemption

Nevada sets minimum wage statewide through constitutional and statutory provisions, preempting local wage ordinances and standardizing employer obligations.

Paid Leave Preemption

Arizona preempts most local paid leave mandates, while requiring statewide earned paid sick time under Proposition 206 and ARS 23-371.

Nevada requires private employers with 50+ employees to provide paid leave, with statewide standards limiting local government modification of leave rules.

Erosion Control

Arizona bans discharging pollutants to protected waters without an AZPDES permit under A.R.S. § 49-255.01. Construction sites disturbing one acre or more must obtain ADEQ's Construction General Permit and implement erosion and sediment controls through a Stormwater Pollution Prevention Plan.

Nevada bans discharging sediment-laden stormwater or any pollutant into state waters without an NDEP permit under NRS 445A.465, the core of the state's erosion and construction-runoff controls.

Flood Zones

Arizona statutorily delegates floodplain regulation to counties and flood control districts, setting uniform minimum standards for development in mapped floodplains statewide.

Nevada participates in the National Flood Insurance Program through the Division of Water Resources under NRS Chapter 540, requiring participating local governments to adopt floodplain management ordinances meeting FEMA minimum standards as a condition of flood insurance availability.

Stormwater Management

Arizona regulates stormwater discharges through the AZPDES program under ARS Title 49, requiring permits for construction, industrial, and municipal stormwater statewide.

Nevada Division of Environmental Protection administers federal NPDES stormwater permits statewide under NRS 445A.300, requiring construction sites over one acre and industrial facilities to obtain coverage and implement pollution prevention measures.

Neighbor Fence Rules

Arizona is an open-range state. Under A.R.S. 3-1427, a landowner cannot recover for damage caused by a neighbor's trespassing livestock unless the property is enclosed within a 'lawful fence' meeting the four-wire standard of A.R.S. 3-1426.

Outdoor Burning

Arizona regulates open burning through ADEQ air quality rules and DFFM forestry statutes, requiring permits for most outdoor burns and prohibiting burns during no-burn declarations.

Propane Storage

Nevada regulates liquefied petroleum gas storage and handling statewide under NRS 590 and NAC 590, adopting NFPA 58 by reference and licensing dealers, installers, and bulk storage facilities through the Board for the Regulation of Liquefied Petroleum Gas.

Wildfire Zones

Nevada Division of Forestry administers wildland-urban interface fire safety under NRS 472 and NRS 527, requiring defensible space around structures in fire hazard zones and authorizing local enforcement of state-adopted WUI codes.

Concealed Carry

Arizona allows permitless concealed carry for adults 21 and older, while still issuing optional CCW permits that enable reciprocity with other states.

Nevada is a shall-issue state requiring a permit to carry concealed firearms, with sheriff-issued CCW permits valid for five years subject to training requirements.

Local Firearms Preemption

Arizona broadly preempts cities, towns, and counties from regulating firearms, ammunition, components, and related accessories beyond state law.

Nevada law preempts local firearm ordinances, reserving regulation of firearms, ammunition, and components to the state legislature, with narrow exceptions.

Open Carry

Arizona permits open carry of firearms by adults 18 and older without a license in most public spaces, subject to limited location restrictions.

Nevada generally permits open carry of firearms by adults without a permit, subject to location restrictions and the state preemption framework.

Food Truck Permits

Arizona Department of Health Services regulates mobile food units statewide under A.R.S. Title 36, Chapter 8 and uniform food code rules in A.A.C. Title 9, applied through county health permits.

Nevada regulates mobile food establishments through NRS 446 and NAC 446. Food trucks must obtain health permits from county health districts, comply with FDA Food Code adopted statewide, and operate from licensed commissaries. Standards apply uniformly across Nevada.

Casino Zoning Districts

Nevada law won't let the Gaming Commission license a full casino inside the Las Vegas Boulevard corridor or the rural Clark County gaming zone unless the site sits in a designated gaming enterprise district. Statewide, any county with 100,000+ residents also caps nonrestricted licenses to resort hotels, buildings with 200-300+ rooms, a 24/7 restaurant and a bar, under NRS 463.1605.

Charitable Bingo and Raffles

Arizona lets a nonprofit with federal 501(c) tax-exempt status run a raffle without a gambling license under A.R.S. Section 13-3302(B), so long as it has operated in-state for a full year, keeps no insider pecuniary benefit, and lets only local members run the drawing. Bingo works differently: any organization that wants to deal cards must first get a Class A, B or C license from the Department of Revenue, taxed 1.5% to 2.5% of receipts under Sections 5-413 and 5-414.

Nevada regulates charitable bingo, poker, blackjack and raffle-style lotteries entirely through NRS Chapter 462, administered by the Nevada Gaming Control Board. Only a "qualified organization", a certified nonprofit or IRS-recognized charity, may hold one, and only after the Board's Chair registers it under NRS 462.150. Annual prize payouts are capped at $500,000, or $2 million for organizations affiliated with a major pro sports franchise playing in Nevada.

Sports Betting Law

Arizona legalized event wagering, commonly called sports betting, in 2021 under Arizona Revised Statutes Title 5, Chapter 11. The Department of Gaming may issue no more than ten event wagering operator licenses to non-tribal applicants, Arizona pro sports teams, PGA Tour host venues, or NASCAR national-touring-race promoters, or their designees, and no more than ten to Indian tribes that have signed the current tribal-state gaming compact. Offering event wagering without one of these licenses is unlawful statewide.

Nevada legalized sports wagering statewide long before other states, but you can only bet through a sports pool licensed under NRS 463.160. Operating a race book or sports pool without that license is a category B felony under NRS 463.360, punishable by up to 10 years in prison and a $50,000 fine. Mobile wagering runs through the same licensed operator's app.

Assessment & Dues

Under A.R.S. § 33-1807, unpaid assessments in an Arizona planned community become an automatic lien on the lot, and the association may charge late fees and interest if the declaration allows. The lien may be foreclosed like a mortgage, but only once the owner is delinquent 18 months or owes $10,000 or more.

Under the Nevada Common-Interest Ownership Act, NRS 116.3116, an association has a statutory lien for unpaid assessments. A portion is super-priority over a first mortgage, and the association may foreclose nonjudicially without going to court, following the notice procedures in NRS 116.31162 to 116.31168.

Flag Display Rights

Arizona law bars homeowners associations from banning outdoor display of eight protected flags, including the American, Arizona state, POW/MIA, Gadsden and first responder flags. Under A.R.S. § 33-1808, an association may cap displays at two wall-mounted flagpole holders, two flags flying at once, and flagpole height at the member's rooftop line, but it cannot forbid installing a flagpole in the front or back yard.

NRS 116.320 forbids a Nevada homeowners association, and the association's own governing documents, from banning display of the flag of the United States or the flag of the State of Nevada anywhere an owner has the right to occupy and use exclusively, which covers a front yard, back yard, patio, balcony or window of the unit. The protection is deliberately narrow: only those two flags are named, so a military branch, POW/MIA, first-responder, team or seasonal flag has no statutory shield in a Nevada common-interest community. The board may still adopt rules that reasonably restrict the placement and manner of the display, and the flag itself must be cloth, fabric or paper flown from a pole or staff or hung in a window. Whoever wins a lawsuit brought to enforce the section recovers reasonable attorney's fees and costs.

HOA Fines & Enforcement

Arizona law caps how much a homeowners association can fine a member and forces the board to give notice and a hearing first. A.R.S. § 33-1803 limits late charges on an unpaid penalty to the greater of $15 or 10 percent, sets a 21-day certified-mail window to contest a violation notice, and requires the association to answer within 10 business days or lose its right to collect attorney fees during the dispute.

For a violation of the governing documents that does not pose an imminent threat of causing a substantial adverse effect on health, safety or welfare, NRS 116.31031 limits a Nevada association's fine to $100 for each violation and a total of $1,000 per hearing against each owner, tenant or invitee, and the amount must still be commensurate with the severity of the violation. The board may impose nothing at all unless the owner received written notice of the governing-document provision at least 30 days before the alleged violation, then a detailed violation notice with a photograph, the proposed cure, the fine amount and a hearing date, and a real chance to cure or contest. If the violation is not cured within 14 days it becomes a continuing violation and the board may add a fine of no more than the original amount for each 7-day period. Nevada also bars foreclosure over an ordinary fine and caps collection charges by regulation.

Cottage Food Operations

Arizona lets you cook for sale in your own kitchen once you register with the Department of Health Services and hold a current food handler certificate from an accredited program. A.R.S. § 36-136(I)(4)(g) exempts cottage food products made in a private home for commercial purposes from the state food establishment rules, so there is no licence, no inspection and no annual sales cap. What Arizona does impose is a packaging and labeling regime under A.R.S. § 36-932, plus separate delivery rules for anything containing dairy, meat or poultry and for anything that needs temperature control.

Nevada moved its cottage food rule out of NRS chapter 446 in 2025. The section in force today is NRS 580.600, which keeps a home cottage food operation outside the definition of a food establishment so long as gross sales stay at or under $100,000 per calendar year, the goods come from a closed list of shelf-stable items, every package carries the words MADE IN A COTTAGE FOOD OPERATION THAT IS NOT SUBJECT TO GOVERNMENT FOOD SAFETY INSPECTION, and every sale is an in-person transaction. Selling by telephone or over the Internet is what takes you out of the exemption, not the size of the batch. You must register with the food safety authority before your first sale, but there is no permit, no plan review and no routine inspection, and no Nevada city or county may adopt an ordinance prohibiting a person from preparing food in a cottage food operation.

Home Daycare

Nevada requires state licensing through the Division of Public and Behavioral Health for any home caring for more than four unrelated children, setting uniform background-check, capacity, and safety standards under NRS 432A that override most local prohibitions.

Home Kitchen Operations

Arizona has no home restaurant permit. There is no microenterprise home kitchen operation licence, no meal count allowance, and nothing in A.R.S. § 36-136(I)(4) that exempts a home kitchen serving cooked-to-order meals from the state food establishment rules. The only commercial route out of a private kitchen is cottage food registration under A.R.S. Title 36, Chapter 8, Article 2, and A.R.S. § 36-932(A) makes that a packaged-goods scheme: products "must be packaged at home with an attached label." Serving plates to guests at your address, or cooking meals to order for pickup, falls outside every exemption Arizona has written.

Nevada never created a microenterprise home kitchen operation. The words microenterprise and home kitchen appear nowhere in NRS chapter 580 or NAC chapter 446. What Nevada does have is more unusual: a home kitchen may be permitted as an ordinary food establishment. NRS 580.050(2)(a) pulls a private home into the definition of a food establishment the moment food prepared there is sold, NRS 580.900(4) says home-prepared food may not be sold unless the preparer holds a valid permit for that purpose, and NAC 446.576 sets the four physical conditions: full compliance with the food establishment chapter, a dedicated exterior entrance, physical separation from the living or sleeping quarters by walls or self-closing doors, and no use of those areas as thoroughfares. Once the permit issues, that part of the house legally stops being a residence and becomes an inspected food establishment.

Recording Police

Arizona's only statute aimed at filming police, A.R.S. § 13-3732, has never taken effect. It would have made it a class 3 misdemeanor to keep video recording law enforcement activity within eight feet of it after a verbal warning, but the U.S. District Court for the District of Arizona enjoined its enforcement on September 9, 2022, about two weeks before its effective date, and the Attorney General filed a notice of non-opposition. The section still prints in the Arizona Revised Statutes with no injunction note, so reading the code alone gives the wrong answer. What actually governs is Arizona's one-party consent wiretap exemption in A.R.S. § 13-3012(9) and the interference offenses, which require force, a threat of force, or physical involvement in an arrest.

Nevada does not leave the right to film police to case law. NRS 171.1233, added in the 2020 32nd Special Session, says a person who is not under arrest or in the custody of a peace officer "may record a law enforcement activity and maintain custody and control of that recording," and subsection 2 then lists five things a peace officer "shall not" do, including threatening you for recording, ordering you to stop when you were lawfully entitled to record, and stopping, seizing or searching you because you recorded. The section defines "law enforcement activity" as any activity by a peace officer acting under color of law, and defines "record" broadly enough to cover written notes and a live broadcast. The one boundary is written into subsection 1 itself: the right does not authorize you to interfere with or obstruct the activity you are filming.

Stop & Identify Laws

Arizona does have a stop-and-identify statute, but it is a narrow one. A.R.S. § 13-2412 compels you to state your true full name only after a peace officer has lawfully detained you on reasonable suspicion of a crime and has first advised you that refusing to answer is unlawful. The same subsection says you cannot be compelled to answer any other question, and it asks for a spoken name rather than a document. Refusing is a class 2 misdemeanor, punishable by up to four months in jail and a fine of up to $750.

Nevada is a stop-and-identify state, and the duty sits in a statute rather than in case law. NRS 171.123 lets a peace officer detain anyone the officer encounters under circumstances reasonably indicating a crime or civil infraction, and subsection 3 says the person detained "shall identify himself or herself, but may not be compelled to answer any other inquiry of any peace officer." Subsection 4 caps the whole detention at 60 minutes and keeps it at the place where it began unless the person is arrested. Refusing to give a name is charged under NRS 199.280 as resisting, delaying or obstructing a public officer, a misdemeanor when no weapon is involved, and that is the prosecution the United States Supreme Court reviewed in the Humboldt County case of Hiibel.

Native Plants

The Arizona Native Plant Law protects designated cacti, trees, and other species from destruction or removal without state permits, applying universally on private and public land regardless of municipal rules.

NRS 527.260 through 527.300 establishes a statewide program to protect, conserve, and restore native flora threatened with extinction, requiring permits from the State Forester Firewarden before any listed species can be removed or destroyed.

Rainwater Harvesting

Nevada law explicitly permits de minimis rainwater collection from single-family rooftops for nonpotable domestic use, including watering family gardens, under NRS 533.027 enacted by Assembly Bill 138 in 2017.

Tree Removal & Heritage Trees

Arizona protects native trees such as ironwood, mesquite, and palo verde under the Native Plant Law, requiring state permits and notice before removal even on private residential property.

Water Restrictions

Arizona regulates groundwater use through Active Management Areas (AMAs) under the 1980 Groundwater Management Act, applying mandatory conservation requirements to municipal water providers in five designated regions, including Phoenix and Tucson.

Weed Ordinances

NRS 555.150 requires every person who owns, controls, or occupies land in Nevada, along with railroads, canal and ditch companies, counties, and cities, to control weeds the State Quarantine Officer has designated as noxious. Enforcement runs through written notice, county-funded forced control if an owner ignores it, a lien for unpaid costs, and civil penalties reaching $1,000 per repeat violation.

Aircraft Noise

Arizona law forces cities, towns, and counties holding land in a military airport's high noise or accident potential zone to adopt compatibility plans and enforce zoning that shields residents from aircraft noise, backed by civil penalties reaching $50,000.

Dark Sky Rules

Arizona regulates outdoor lighting statewide through the Outdoor Light Control statutes, requiring shielded fixtures and limits on certain lamp types, particularly in counties hosting major astronomical observatories.

Eviction Notice & Process

Under A.R.S. § 33-1368, Arizona landlords must give a 5-day written notice for nonpayment of rent and a 10-day notice to cure for other material lease violations before filing. Material and irreparable breaches allow immediate termination. Evictions proceed as special detainer actions under A.R.S. § 33-1377, with trial set 3–6 days out.

For nonpayment, NRS 40.253 requires a 7-judicial-day pay-or-quit notice before summary eviction. Nevada uses a unique 'tenant-initiated' process: the tenant must file an affidavit (answer) with the justice court to contest the eviction, and a court order issues if no affidavit is filed in time.

Landlord Entry & Notice

Under A.R.S. § 33-1343, an Arizona landlord must give at least two days' notice of intent to enter and may enter only at reasonable times for legitimate purposes such as inspections, repairs, or showings. No notice is required in a genuine emergency, and access may not be abused to harass the tenant.

NRS 118A.330 requires a Nevada landlord to give the tenant at least 24 hours' notice before entering and to enter only at reasonable times during normal business hours, except in an emergency. The landlord may not abuse the right of access or use it to harass the tenant.

Late Fees & Grace Periods

NRS 118A.210 caps a Nevada late fee at 5 percent of the periodic rent and requires it to be set out in the rental agreement. For tenancies longer than week-to-week, no late fee may be charged until at least 3 calendar days after rent is due, and fees may not be compounded.

Lease Termination & Notice to Vacate

A.R.S. § 33-1375 requires 30 days' written notice to end a month-to-month tenancy (10 days week-to-week). Breaking a fixed-term lease early can incur damages, though landlords must mitigate. A.R.S. § 33-1318 lets domestic-violence and sexual-assault victims terminate early; military servicemembers terminate under the federal SCRA.

Under NRS 40.251, either party may end a month-to-month tenancy with 30 days' written notice (7 days for week-to-week). Tenants who are 60 or older or have a disability may request an additional 30 days. Fixed-term leases end on their stated date; military servicemembers may terminate under the federal SCRA.

Rent Control

Arizona prohibits local rent control. State law makes rent regulation on private residential property a matter of statewide concern and preempts the field, so cities, charter cities, towns, and counties cannot cap or freeze rents on private housing. There is no statewide rent cap, leaving private rents to the market.

Repairs & Habitability

A.R.S. § 33-1324 requires Arizona landlords to keep rentals fit and habitable: meeting building codes, maintaining electrical, plumbing, heating and cooling systems, and supplying running water and heat. If a landlord fails to act, A.R.S. § 33-1361 lets tenants terminate after a 5-day or 10-day notice, and § 33-1363 allows repair-and-deduct.

NRS 118A.290 requires Nevada landlords to keep rentals habitable: sound structure, weatherproofing, working plumbing, heating, electrical, and a safe water supply. NRS 118A.360 lets tenants repair-and-deduct after written notice, and NRS 118A.380 lets tenants act when essential services such as heat, water, or electricity fail.

Security Deposit Rules

Arizona caps security deposits at one and one-half month's rent. After the tenancy ends and the tenant requests it, a landlord has 14 days (excluding weekends and legal holidays) to return the deposit with an itemized list of deductions. Wrongful retention exposes the landlord to damages of twice the amount withheld.

Nevada caps a residential security deposit, including any surety bond and last month's rent, at three months' periodic rent. After the tenancy ends, the landlord has 30 days to return the remaining deposit with an itemized written accounting. Wrongful retention can expose the landlord to the entire deposit plus an equal court-set sum.

Squatter's Rights & Adverse Possession

Arizona's adverse possession periods are tiered: 2 years by right of possession alone (A.R.S. § 12-522), 3 years under color of title (§ 12-523), 5 years under a recorded deed with taxes paid (§§ 12-524, 12-525), and a 10-year catch-all (§ 12-526). Possession must be open, hostile, and continuous; removal is by court action.

Nevada requires 5 years of continuous, adverse occupancy plus payment of all state, county, and municipal taxes for that period before a claim of adverse possession can succeed (NRS 11.150; NRS 40.090). Separately, unlawful occupancy of a vacant dwelling is a criminal gross misdemeanor under NRS 205.0817.

Agricultural Zoning Protection

Arizona limits local zoning power over agricultural land, protecting commercial farming activities from overly restrictive land-use regulation.

Farm Nuisance Protection

Arizona's Right to Farm Act in ARS 3-112 protects established agricultural operations from nuisance suits when surrounding land use changes.

Nevada protects established agricultural operations from nuisance claims when farming activities pre-date conflicting non-agricultural land uses in the area.

Insurance Requirements

A.R.S. 9-500.39 requires Arizona short-term rental operators to maintain at least $500,000 in liability insurance or rent through a marketplace providing equivalent coverage.

Noise Rules

A.R.S. 9-500.39 lets Arizona cities apply local noise ordinances to short-term rentals and impose escalating penalties for verified noise violations occurring on the premises.

Occupancy Limits

A.R.S. 9-500.39 lets Arizona cities cap nightly occupancy at two adults per bedroom plus additional persons, applying uniformly to short-term rentals statewide.

Taxes & Fees

Arizona requires short-term rental operators to license with the Department of Revenue and remit transaction privilege tax plus any applicable county and city transient lodging taxes statewide.

Nevada imposes statewide transient lodging taxes on short-term rentals, including combined state and local rates that platforms or hosts must collect and remit on stays under 30 days, regardless of municipality.

Political Signs

Arizona state law preempts municipal restrictions on temporary political signs in public rights-of-way during election periods, limiting what cities and counties can prohibit or remove.

Nevada law protects the right of residents to display political signs on their private property and limits the ability of homeowners associations to restrict political speech, though local governments may regulate size, placement, and duration consistent with the First Amendment.

Plastic Bag Rules

Arizona prohibits cities, towns, and counties from regulating or banning auxiliary containers like plastic bags, cups, and bottles under ARS 9-500.38.

Polystyrene Foam Rules

Arizona preempts local bans and fees on polystyrene foam food containers as auxiliary containers under ARS 9-500.38 and ARS 11-269.16.

Panel Permits

Arizona requires expedited residential solar permitting under SolarAPP+ adoption laws and provides statewide property tax exemptions for residential solar energy devices under A.R.S. Section 42-11054.

Nevada protects residential solar but has no statewide SolarAPP+ or one-day permit mandate. NRS 278.0208 bars prohibiting or unreasonably restricting solar systems, and NRS 278.580 requires local building codes to permit solar; permitting is handled locally.

Solicitor Permits

Nevada requires charitable organizations and professional fundraisers soliciting donations to register with the Secretary of State under NRS 82A, in addition to any local door-to-door solicitor permits, with disclosure rules applying statewide.

Fencing & Safety Requirements

Arizona enforces a uniform statewide swimming pool enclosure law requiring barriers around residential pools, with cities and counties bound to minimum standards but allowed to adopt stricter local rules.

Flavored Tobacco Bans

Nevada has no statewide ban on flavored tobacco or vapor products, leaving flavor regulation primarily to federal FDA authority and limited local action.

Tobacco Age Restrictions

Arizona bans the sale or furnishing of tobacco, vapor, and alternative nicotine products to anyone under 21 under A.R.S. 13-3622. The state raised its own minimum age from 18 to 21 in 2025 to match the federal Tobacco 21 standard.

Nevada prohibits the sale of tobacco, vapor, and alternative nicotine products to anyone under 21 years old, aligning with federal Tobacco 21 law.

Recycling Requirements

Arizona forbids selling plastic bottles and rigid containers unless they carry a molded resin identification code, the familiar number inside the chasing-arrows triangle. A.R.S. § 49-835 has mandated this labeling statewide since July 1, 1991.

Nevada sets a statewide target of recycling at least 25 percent of municipal solid waste. The State Environmental Commission writes the rules requiring source separation of recyclables from homes and public buildings, plus recycling centers.

Radar Detector Rules

A radar detector is legal in a private vehicle anywhere in Arizona. The state's vehicle equipment article, A.R.S. sections 28-921 through 28-966, names no radar detector, laser jammer or speed measuring countermeasure of any kind, and section 28-921(B) states positively that the article does not prohibit the use of additional parts and accessories on a vehicle where the use is not inconsistent with the article. Two real limits survive. Where you stick it matters, because section 28-959.01(B) bars any object placed in or on the vehicle in a manner that obstructs or reduces the driver's clear view through the windshield. And a detector is prohibited outright in a commercial motor vehicle under 49 C.F.R. section 392.71, which Arizona enforces against commercial traffic through Title 28, chapter 14.

Nevada traffic law says nothing whatever about radar detectors. The word does not appear in NRS chapters 484A through 484E, which together are the whole of the state traffic code, nor in NAC chapter 484D, the vehicle-equipment regulation, so mounting and using a detector in a private car is not an offence anywhere in Nevada. The only Nevada rule that reaches detectors is regulatory and applies to trucks: NAC 706.2471 has the Department of Motor Vehicles adopt 49 C.F.R. Parts 390 to 393 as those regulations existed on May 30, 2012, which carries the federal prohibition at 49 C.F.R. section 392.71 into Nevada law for commercial motor vehicles. Nevada rewrites the size threshold for that ban at 10,001 pounds in interstate commerce and 26,001 pounds intrastate.

Studded Tire & Chain Rules

Arizona lets you run metal studded tires anywhere in the state from October 1 to May 1, and bans them for the other five months. A.R.S. § 28-958(B)(3) also caps the hardware itself: the studs may put no more than three per cent of the tire's total road-contact area in metal, and they must be tungsten carbide or another suitable material set into a pneumatic tire. Tire chains sit under a separate exception with no calendar limit, but only when snow, ice or similar skid conditions actually make them necessary. Running studs after May 1 is a civil traffic violation under A.R.S. § 28-121(B), not a criminal offence.

Nevada allows metal studded tires only between October 1 and April 30, and only where the studs are tungsten carbide or similar material and the metal touching the pavement never exceeds 3 percent of the tire area in contact with the roadway. Retractable studs are treated differently: those tires may stay on the vehicle all year, but the studs may only be engaged or extended inside that same October to April window. The rule is statewide, with no separate northern Nevada or mountain county exception, and it sits inside a general ban on any metal or wood protuberance projecting past the tread. A violation is a civil infraction rather than a crime, carrying a civil penalty of up to $500.

Underglow & Auxiliary Lighting

Arizona allows a vehicle four kinds of extra forward lighting and puts a mounting-height band on each: one spot lamp, two fog lamps mounted 12 to 30 inches off the ground, two auxiliary passing lamps mounted 24 to 42 inches, and two auxiliary driving lamps mounted 16 to 42 inches. No more than four front lamps projecting a beam greater than 300 candlepower may be lit at any one time on a highway. Anything visible from directly in front of the vehicle must be amber or white, never red or red and blue, and flashing lights are barred outside a short list that covers emergency vehicles, school buses, snow removal equipment, warning lamps on a disabled or parked vehicle, and turn signals.

Nevada counts auxiliary lamps rather than rating them. NRS 484D.180 lets any motor vehicle carry up to two spot lamps, up to two auxiliary driving lamps mounted 16 to 42 inches above the ground, up to two auxiliary passing lamps mounted 24 to 42 inches, and up to two fog lamps mounted 12 to 30 inches, each with its own aiming rule. NRS 484D.220(2) then caps how many may burn together: where a vehicle has headlamps plus any auxiliary lamp, spot lamp or other front lamp throwing more than 300 candle power, no more than four of them may be lighted at one time on a highway. Colour is fixed separately by NRS 484D.145, and a permanently mounted flashing amber warning light needs a permit from the Nevada Highway Patrol that costs $2 for a single vehicle and expires every June 30.

Window Tint Limits

Arizona lets the front side windows carry film with a light transmission of thirty-three percent plus or minus three percent, so a front window measuring down to 30 percent still complies, and it sets no darkness limit at all on the side windows behind the driver or on the rear window. Every tinted pane, front and rear, is capped at a luminous reflectance of thirty-five percent plus or minus three percent, which is what rules out mirrored and heavily metallic film. On the windshield the state allows a tint strip across the topmost portion provided the bottom edge of the material sits at least twenty-nine inches above the undepressed driver's seat and the strip is not red or amber. Arizona has no periodic passenger-vehicle safety inspection, so all of this is checked at the roadside rather than at a testing station.

Nevada allows aftermarket film on the two windows beside the driver only if the glass and film together pass at least 35 percent of the light striking them, with a statutory tolerance of 7 percent, and only if the film is nonreflective. Behind the driver, NRS 484D.440 sets no light-transmission figure at all: the rear side windows and the rear window may be tinted to any darkness provided the vehicle carries an outside mirror on each side giving the driver a 200-foot view to the rear. The windshield may carry film only across its topmost strip, whose bottom edge must sit at least 29 inches above the undepressed seat, and that strip may not be red or amber. Nevada runs no annual safety inspection, so the rule is enforced at the roadside as a civil infraction that carries no demerit points.
