Inyo County, CA Ordinances (2026)

Unincorporated Inyo County has no countywide residential quiet-hours ordinance for private property. Defined quiet hours exist only in county parks and campgrounds under Inyo County Code Chapter 12.16: 10 p.m. to 8 a.m. daily, except Tecopa Hot Springs Park (8 p.m. to 8 a.m.). Nighttime noise elsewhere is addressed through nuisance enforcement and California Penal Code 415.

Inyo County has no dedicated ordinance setting allowed hours for residential construction noise in unincorporated areas. Building work is governed by permit and zoning rules (Title 18), not a noise-hours rule. Disruptive construction noise is addressed through general nuisance enforcement (Title 22) and California Penal Code 415. No specific start/stop times or decibel limits are set in the County Code.

Inyo County sets no numeric decibel limits for industrial noise but controls it qualitatively through zoning. Title 18 restricts uses that create objectionable noise, vibration, glare or odor, and intensive or industrial uses generally require a conditional use permit so the Planning Commission can impose noise conditions. The General Plan Noise Element guides land-use compatibility.

Inyo County does regulate barking dogs. Under County Code Chapter 8.20, in designated densely populated areas dogs must be leashed and must not habitually make loud noises or constitute a public nuisance. The zoning animal-maintenance rule (Code 18.78.310) also bars any owner from letting an animal obstruct neighbors' comfortable use of property by barking, howling or making other noises.

Inyo County cannot regulate aircraft-in-flight noise - it is preempted by the federal government (FAA), which controls airspace and aircraft operations. California addresses airport noise through the State Aeronautics Act and Title 21 of the Code of Regulations for permitted airports. The County's role is land-use planning around airports and airport operation, not setting in-flight noise limits.

Unincorporated Inyo County has no ordinance specifically regulating leaf blowers - no ban, no hour restrictions, and no decibel cap in the County Code. Leaf-blower noise that disturbs neighbors is handled under general nuisance enforcement (Title 22) or California Penal Code 415. California's statewide phase-out of new gas leaf blowers is a product-sales rule, not a county ordinance.

Unincorporated Inyo County has no standalone amplified-sound permit ordinance for private property, but County Code 12.16.110 prohibits disturbing the peace by loud or unusual noise in county parks. Off park property, amplified music that disturbs others is handled as a nuisance (Title 22) or under California Penal Code 415. Larger events on public land may require use permits.

Vehicle noise in unincorporated Inyo County is governed mainly by California state law, not a county ordinance. The Vehicle Code requires an adequate muffler (VEH 27150) and prohibits modified exhaust that amplifies noise (VEH 27151), with in-use highway limits in VEH 23130. The County's park code (12.16.110) also bars disturbing the peace with automobile horns and noise-making devices.

Unincorporated Inyo County sets no numeric decibel (dBA) noise limits in its Code. Noise is regulated qualitatively - as a loud or unusual noise disturbing the peace (park code 12.16.110) or as objectionable noise from a use (zoning Ch. 18.78). The decibel standards that apply locally come from California state law, chiefly vehicles and permitted airports.

Unincorporated Inyo County has no dedicated outdoor-music ordinance for private property. In county parks, County Code 12.16.110 bars disturbing the peace by loud or unusual noise, and quiet hours apply (10 p.m.-8 a.m., 8 p.m. at Tecopa Hot Springs). Outdoor music elsewhere is handled as a nuisance (Title 22) or under Penal Code 415; public-land events may need permits.

Unincorporated Inyo County requires a Planning Department permit to operate a short-term rental under County Code Chapter 18.73. All permits must be hosted. STRs are allowed only in OS, RR, R-1 and R-2 zones, and a county-wide moratorium has suspended acceptance of new permit applications since December 2022.

To operate a short-term rental in unincorporated Inyo County, an owner must obtain a Planning Department permit under Chapter 18.73 and separately register with the Inyo County Treasurer-Tax Collector to collect and remit Transient Occupancy Tax. Each permit requires an on-parcel host and current emergency-contact information.

Short-term rentals in unincorporated Inyo County are subject to a 12% Transient Occupancy Tax under County Code Chapter 3.20 (Section 3.20.030). Operators collect the tax from guests and remit it quarterly to the Treasurer-Tax Collector. Failure to remit is a misdemeanor under county code.

Under Inyo County Code Chapter 18.73, short-term rentals in unincorporated areas are limited to two renters per guestroom, not counting children three years old and under. Because all rentals must be hosted, the host occupies a portion of the dwelling during every stay.

Inyo County Code Chapter 18.73 allows a maximum of one vehicle per guestroom at a short-term rental, and the owner must provide off-street parking for all allowed vehicles. These parking limits must be stated in the rental agreement and in all advertisements for the rental.

Hosted short-term rentals in unincorporated Inyo County are subject to quiet hours from 9:00 p.m. to 7:00 a.m. under Chapter 18.73, and outdoor amplified sound is prohibited. The on-site host must be reachable to respond to noise complaints during every stay.

Inyo County does not allow non-hosted whole-house short-term rentals in unincorporated areas. Since the February 2020 amendment, Chapter 18.73 requires all short-term rentals to be hosted, with the owner or a designated representative residing on the parcel during every guest stay.

Inyo County requires an on-site host for every short-term rental in unincorporated areas. Under Chapter 18.73, the owner or a designated representative must reside on the parcel for the entire duration of each guest stay and be readily available to handle questions or complaints.

Inyo County's Chapter 18.73 does not cap the number of nights a hosted rental may operate; instead it caps the total number of short-term rental permits in each designated area (from about 2 in the Starlite area to 29 in the South/Southeast County). A moratorium has also halted new permits since December 2022.

Inyo County Code Chapter 18.73 requires owners to maintain insurance applicable to short-term rental activities on the dwelling where the rental occurs. The ordinance mandates that such coverage be kept in force but does not, in its text, set a specific minimum coverage dollar amount.

Inyo County has no countywide ban on state-approved 'safe and sane' fireworks. California Health & Safety Code Section 12500+ governs: only fireworks approved and labeled 'safe and sane' by the State Fire Marshal are legal; all 'dangerous fireworks' (firecrackers, skyrockets, Roman candles, bottle rockets) are illegal statewide. Fireworks are separately prohibited in all county parks and campgrounds.

Recreational fires in a fireplace, barbecue, or fire pit are allowed in unincorporated Inyo County under Great Basin Unified Air Pollution Control District (GBUAPCD) Rule 406, provided the material burned is free of household, municipal, and industrial waste such as tires, tar, plastics, and wet wood. CAL FIRE and local fire agencies may impose seasonal restrictions.

Open burning of refuse in unincorporated Inyo County is generally prohibited under GBUAPCD Rule 406. Limited residential burning of dry natural vegetation is allowed only on a 'burn day' declared by the California Air Resources Board AND with a valid burn permit from the local fire agency. Burning trash, garbage, and industrial waste is never allowed.

Property owners in the State Responsibility Area of unincorporated Inyo County must maintain 100 feet of defensible space around buildings under California Public Resources Code Section 4291, enforced by CAL FIRE. Clearance extends to the property line where it is less than 100 feet. Inyo's Eastern Sierra foothills include Fire Hazard Severity Zones where this requirement applies.

Backyard recreational fires in unincorporated Inyo County are allowed in a fire pit, fireplace, or barbecue under GBUAPCD Rule 406 without a burn permit, as long as only clean wood is burned (no garbage, plastics, tar, tires, or wet wood). Cooking fires are also exempt. CAL FIRE or local fire restrictions can suspend open fires.

Smoke alarm rules in unincorporated Inyo County follow California law. Health & Safety Code Section 13113.7 requires State Fire Marshal-approved smoke alarms in dwellings intended for human occupancy, and the California Residential Code (adopted by Inyo County through Title 24) requires alarms in each bedroom, outside each sleeping area, and on every story. Rental owners must keep alarms operable.

Propane (LP-gas) storage in unincorporated Inyo County follows the California Fire Code, which the county adopts through Title 24 (Inyo County Code Chapter 14.08). California Fire Code Chapter 61 and NFPA 58 govern tank installation, clearances, and permits. Installation permits are required, and distributors may not fill a container unless an installation permit has been issued.

Most of unincorporated Inyo County is State Responsibility Area protected by CAL FIRE (San Bernardino-Inyo-Mono Unit). The State Fire Marshal classifies wildland areas as Moderate, High, and Very High Fire Hazard Severity Zones; portions of Inyo's Eastern Sierra foothills and wildland-urban interface fall in these zones, triggering defensible-space (PRC 4291) and fire-resistant construction (Chapter 7A) requirements.

Outdoor cooking with a barbecue or propane grill is allowed in unincorporated Inyo County. GBUAPCD Rule 406 exempts cooking fires and barbecue fires from the open-burning prohibition. Propane appliances and cylinders follow the California Fire Code (Chapter 61 / NFPA 58). During high fire danger, CAL FIRE or local agencies may restrict open-flame cooking.

Using a wood or charcoal smoker for cooking is allowed in unincorporated Inyo County. GBUAPCD Rule 406 exempts fires used only for cooking food, so no burn permit or 'permissive burn day' is required. Smokers must burn only clean fuel (wood, charcoal, pellets), never trash or treated wood. Fire restrictions may apply during high fire danger.

Inyo County's adopted on-street rule targets tall vehicles (seven feet or more, including any load) near Highway 395 intersections in Lone Pine rather than RVs by name. Most RV, trailer and boat parking on county roads otherwise falls under the California Vehicle Code and county zoning for private property.

On unincorporated county roads, Inyo County Code Title 10, Chapter 10.36 governs stopping, standing and parking. The chapter prohibits stopping or parking that conflicts with traffic, signs or markings, and incorporates the California Vehicle Code's general parking restrictions, including the 72-hour rule.

Inyo County does not impose a blanket overnight on-street parking ban in the unincorporated area. The notable overnight rule is in Independence, where commercial trucks of 10,000 pounds or more are banned from designated residential streets between 2 a.m. and 6 a.m. The Vehicle Code's 72-hour rule otherwise applies.

Inyo County restricts heavy commercial vehicles in specific places. In Independence, trucks rated 10,000 pounds or more are banned from a designated residential stretch of South Washington Street between 2 a.m. and 6 a.m. Chapter 10.36 also addresses weight limitations on certain county highways.

Inyo County Code Title 10, Chapter 10.64 (Abandoned Vehicles) declares abandoned, wrecked, dismantled or inoperative vehicles on public or private property to be a public nuisance subject to abatement. The Director of Public Works administers the program under California Vehicle Code Section 22660.

Inyo County has no special on-street driveway-parking ordinance unique to the unincorporated area; blocking a driveway is handled under the California Vehicle Code. New or modified driveway connections to county roads require a Public Works encroachment permit, and parking surfaces on private lots are addressed by the Title 18 zoning ordinance.

Inyo County's signature oversized-vehicle rule is height-based: under Title 10, Chapter 10.36, vehicles seven feet or more in height (including any load) may not park near designated Highway 395 intersections in Lone Pine between 8 a.m. and 6 p.m. Violating vehicles are towable under CVC 22651(k).

Inyo County has adopted an expedited electric vehicle charging system permitting process under its building code (Title 14), as required by California Government Code Section 65850.7. The county streamlines permits and adopts a compliance checklist while preserving the building official's life-safety authority.

Loading, standing and special zones on unincorporated county roads are established under Title 10, Chapter 10.36 (Stopping, Standing and Parking). The chapter ties parking limits to curb markings and signs and preserves the more restrictive provisions of the California Vehicle Code.

On unincorporated county roads, curb markings and signs control parking under Title 10, Chapter 10.36 (Stopping, Standing and Parking). Inyo County follows the California Vehicle Code curb-color scheme - red means no stopping, with yellow, white, green and blue zones for specific uses. Only the county may officially mark curbs.

Inyo County has no dedicated beekeeping ordinance in its animal code. Bees fall under the zoning rules for animal maintenance, and California's Food and Agricultural Code requires every apiary owner to register colonies and locations annually with the County Agricultural Commissioner.

Inyo County's code sets no fixed numeric cap on how many dogs or cats a household may keep. However, a property with five or more dogs (five months or older) kept for breeding and sale is a regulated "kennel," and all animal keeping is limited by nuisance and sanitation rules.

Inyo County only requires dogs to be leashed in "densely populated areas" designated by the Board of Supervisors. There, a dog off the owner's premises must be restrained by a leash no longer than six feet. Elsewhere in the unincorporated county there is no countywide leash mandate.

Unincorporated Inyo County's zoning code allows keeping small livestock such as poultry, rabbits, goats, pigs, sheep and pigeons as an accessory use. On small residential lots under one-half acre this is for domestic, educational or youth-agriculture purposes only, and large livestock and commercial operations are prohibited.

Inyo County's dog code does not impose breed-specific bans or breed-specific spay/neuter mandates. Instead, any dog may be declared "vicious" individually based on its behavior. Differential licensing fees apply to unaltered dogs of all breeds, and California law bars breed-specific bans.

Inyo County Code Chapter 8.24 regulates wild or exotic animals, including a specific restriction on transporting skunks into or out of the county except by sheriff's permit for recognized zoos or research institutions. California state law separately bans private possession of most wild and exotic species without a permit.

In unincorporated Inyo County, large livestock such as horses, cattle, mules and donkeys are barred from small residential lots under one-half acre but allowed on larger residential and other-zoned parcels as an accessory use. Open-space and agricultural zones allow livestock ranching, and pens must meet setback limits.

Inyo County exempts domestic cats from its prohibition on animals running at large, so cats are not subject to leash or confinement rules. Cats are not required to be licensed (only dogs are), but adopters of unaltered cats from the shelter must pay a spay/neuter deposit under the County code.

Inyo County's code does not contain a specific blanket ordinance prohibiting the feeding of wild animals, but its animal-maintenance and nuisance provisions discourage attracting wildlife. On the surrounding Inyo National Forest and other public lands, federal food-storage and wildlife rules apply, and California law restricts feeding big game.

Inyo County addresses animal hoarding through its nuisance and care provisions rather than a numeric cap. Owners must provide adequate food, water, shelter and care, may not keep animals in unsanitary conditions, and may not abandon animals. Animal Services can cite violations and impound neglected animals.

In unincorporated Inyo County, the zoning ordinance (Title 18) limits most fences, walls, and hedges to a maximum height of six feet. In required front yards and certain corner-lot yards, the limit drops to three and one-half feet to protect visibility.

A retaining wall over four feet high, measured from the bottom of the footing, requires a building permit under the California Building Code adopted by Inyo County. When a fence sits atop a retaining wall, the County zoning code (Sec. 18.78.160) reduces the allowed fence height.

Inyo County's zoning ordinance caps fence height at six feet, which keeps most fences below the state building-code permit threshold of seven feet. A building permit is required for a fence over seven feet or a retaining wall over four feet, per the adopted California Building Code.

Shared boundary fences in unincorporated Inyo County are governed by California's Good Neighbor Fence Law (Civil Code 841), which presumes adjoining owners benefit equally and share the reasonable cost of a division fence, and requires 30 days' written notice before building or replacing one.

Fences in unincorporated Inyo County may occupy any yard but cannot exceed six feet (three and one-half feet in regulated front and corner-lot yards) under Section 18.78.160. Pool barriers and structures near sight lines have additional building-code and visibility requirements.

Inyo County's Title 18 zoning ordinance regulates fence height and placement (Section 18.78.160) but does not restrict residential fence materials. Common materials such as wood, vinyl, chain link, and masonry are generally allowed within the six-foot height and yard limits.

Standard fence materials are permitted for residential properties in unincorporated Inyo County; Title 18 regulates fence height and placement (Section 18.78.160), not material. The adopted California Building Code and fire/wind conditions are the main influences on material choice.

Building setbacks in unincorporated Inyo County are set per zoning district in Title 18. In the R-1 (One Family Residence) zone, the front yard must be at least 25 feet deep and each interior side yard at least 5 feet. Setbacks differ for RR, R-3, and other zones.

In Inyo County's residential (R) zones, no dwelling may exceed two and one-half stories or 35 feet in height under Title 18. Detached accessory buildings are limited to 20 feet, and features such as chimneys, church spires, and flag poles are exempt from the height limits.

Inyo County's Title 18 does not impose a single percentage lot-coverage cap; buildable area is governed by minimum lot size, required yards, and height per zone. In R-1, the minimum building site is 5,800 sq ft, and an extension may occupy no more than 30% of a required rear yard.

Rainwater harvesting is legal and encouraged. Under California's Rainwater Capture Act of 2012 (AB 1750), landowners may install rain barrels and rooftop capture systems without a state water-right permit or local permit; Inyo County does not prohibit residential rainwater collection.

Inyo County has no decorative lawn-height limit. Overgrown grass and weeds are regulated only when they become a nuisance under Title 22 of the County Code, and as a fire hazard through state defensible-space law (PRC 4291) in fire-prone areas.

Inyo County does not have a private tree-pruning permit ordinance. Owners may trim their own trees. Trimming becomes regulated only for defensible space under state fire law and where it affects a public right-of-way or creates a nuisance under Title 22.

Unincorporated Inyo County has no general tree-removal permit ordinance (no oak or heritage-tree protection law). Owners may remove trees on their own land. Trees on LADWP-owned Owens Valley land, or removal that triggers grading or environmental review, are exceptions.

Inyo County treats overgrown weeds and dead vegetation as abatable nuisances under Title 22 of the County Code, and fire-hazard vegetation is regulated through state defensible-space law (PRC 4291). The County's process emphasizes voluntary compliance before forced abatement.

Day-to-day outdoor watering rules in Inyo County come from California state law, not a county ordinance. Statewide rules ban wasteful uses (hosing pavement, runoff, watering within 48 hours of rain) and AB 1572 phases out potable irrigation of non-functional turf on commercial/institutional sites.

Inyo County's adopted Water Efficient Landscape Ordinance (MWELO) requires new and rehabilitated landscapes to favor low-water plants, bans invasive species, and promotes climate-appropriate planting. There is no county rule forbidding native or drought-tolerant landscaping.

Inyo County has no ordinance banning or restricting artificial turf on private property. Synthetic turf is a recognized way to meet state water-efficiency goals; only general zoning, drainage, and setback rules apply to its installation.

Backyard composting is allowed. California's SB 1383 (effective 2022) requires residents to separate organic waste — food scraps and yard trimmings — from trash and either use collection service or compost/self-haul. Implementation in unincorporated Inyo County is handled through the County's waste program.

Pool safety for new private pools in unincorporated Inyo County is governed primarily by California's Swimming Pool Safety Act, enforced through the County building permit. New pools must include at least two of seven approved drowning-prevention features, and the County zoning code adds placement rules under Title 18.

In unincorporated Inyo County, a building permit is required to construct a swimming pool, jacuzzi/spa, or pool house/cabana, issued by the County Building and Safety Department. Pools are also a permitted accessory use under Zoning Ordinance Title 18 but must meet placement and barrier rules.

Inyo County's Zoning Ordinance (Title 18) treats a protective fence around a swimming pool specially: it is exempt from normal fence height limits if built of wire or steel mesh transmitting at least 90% light. For new pools, the California Swimming Pool Safety Act sets the enclosure and gate standards the County applies.

Above-ground pools in unincorporated Inyo County are treated the same as other pools: a permitted accessory use under Zoning Ordinance Title 18 with a 3-foot setback to fences and walls, and a building permit through County Building and Safety when they hold enough water to fall under the Building Code and the state Pool Safety Act.

Hot tubs, spas, and jacuzzis in unincorporated Inyo County require a building permit from County Building and Safety. Spas are treated as pools under Zoning Ordinance Title 18 (3-foot setback to fences/walls), and new spas at single-family homes fall under the California Swimming Pool Safety Act, though spas with approved safety covers have a simpler compliance path.

Unincorporated Inyo County does not require a tree-removal permit for private trees and has no heritage/oak tree-protection ordinance. Permits arise only indirectly — through grading, larger development/CEQA review, or where trees stand on LADWP-owned Owens Valley land.

Solid waste collection in unincorporated Inyo County is provided by permitted haulers in designated permit areas under Chapter 7.08. Residential waste must be removed at least once a week, and only permitted collectors may haul waste for hire.

Permitted haulers in Inyo County are not required to pick up bulky items or objects weighing more than 60 pounds as part of regular collection. Residents typically self-haul bulky and oversized items to County landfills and transfer stations, where gate and per-ton fees apply.

Under Chapter 7.08, residential solid waste containers are placed adjacent to the public highway or curb for collection. A container plus contents may not exceed 45 pounds, and yard and tree trimmings must be containerized or bundled.

Inyo County offers drop-off recycling at its landfills and transfer stations, but residential recycling is largely voluntary. Under California's AB 341, businesses generating 4+ cubic yards of weekly waste and multifamily complexes of 5+ units must arrange recycling service.

California's SB 1383 mandates organic-waste recycling statewide, but Inyo County qualifies as a low-population rural jurisdiction (under 70,000 residents) and is on CalRecycle's exemption list. It is exempt from organic-waste collection and procurement mandates until January 1, 2037, while other SB 1383 duties still apply.

Unincorporated Inyo County allows home occupations as an accessory use in residential (R), rural residential (RR), and open space (OS) districts under Zoning Ordinance Title 18 (Ch. 18.78). The use must be clearly secondary to the dwelling, with limits on employees, traffic, hours, and outdoor storage.

Signs for home occupations in unincorporated Inyo County are tightly limited so the use stays residential in character. Zoning Ordinance Title 18 governs signs under Chapter 18.75, and home occupations under Chapter 18.78 must not alter the residential character of the premises, which restricts on-site advertising.

A home occupation is allowed as an accessory use in unincorporated Inyo County's residential, rural residential, and open space districts under Zoning Ordinance Title 18 (Ch. 18.78), provided it meets the performance standards in §18.78.130. Activities that exceed those limits may need a conditional use permit.

Inyo County Environmental Health permits cottage food operations under California's Homemade Food Act (AB 1616). Class A allows direct-to-consumer sales; Class B allows direct and indirect sales and requires a home-kitchen inspection. Only approved non-hazardous foods are allowed, and operators must pass a food handler exam.

Family daycare homes in unincorporated Inyo County are protected by California state law (Health and Safety Code §1597 et seq. / SB 234). Small and large family daycare homes are a residential use by right, so County zoning cannot prohibit them or charge a special business license, and the state licenses the provider.

Inyo County's Title 22 Code Enforcement ordinance defines a nuisance to include any violation of the County Code or state law, and prohibits anyone from creating or allowing a nuisance on property they own or control in the unincorporated county.

Inyo County declares uncontrolled grass, weeds, and refuse a public nuisance under Chapter 7.60. The ordinance targets fire-hazard and noxious vegetation rather than a fixed grass height, and the County can abate and lien the cost if owners do not comply.

Inyo County Code Chapter 7.08 requires solid waste to be stored in approved containers. A container plus contents may not exceed 45 pounds at collection, and residential carts are placed adjacent to the public highway or curb for pickup.

Vacant and occupied parcels in unincorporated Inyo County must be kept clear of accumulated refuse and hazardous weeds. Uncontrolled growth or accumulation of grass, weeds, and refuse is declared a public nuisance under Chapter 7.60, and inoperative vehicles are addressed by Chapter 10.64.

Inyo County does not publish a dedicated garage-sale or yard-sale permit ordinance for the unincorporated area. Occasional residential sales are generally treated as a normal residential activity, distinct from a home occupation, with no county sale permit identified in the County Code.

Unincorporated Inyo County permits ADUs and JADUs in all residential and mixed-use zones under Zoning Ordinance Section 18.78.340, with size limits aligned to California state law. Detached ADUs may reach 1,200 sq ft; an 800 sq ft ADU is allowed regardless of lot coverage or floor-area limits.

Sheds and detached accessory structures in unincorporated Inyo County are governed by Title 18 zoning standards (setbacks, height, lot coverage) and Title 14 building regulations. Standards vary by zone; the County's Rural Residential, R-1, and Open Space zones each set their own development limits.

Inyo County allows converting a garage or accessory structure into an ADU under Zoning Ordinance 18.78.340 and California state law. A JADU up to 500 sq ft may be created within an existing single-family dwelling or attached garage; converted ADUs follow the County's ADU standards.

Inyo County regulates carports as accessory structures through Title 18 zoning district standards (setbacks, height, lot coverage) and Title 14 building regulations. There is no separate countywide carport ordinance; requirements depend on the parcel's zoning district.

Inyo County does not have a standalone tiny-home ordinance. A tiny home on a permanent foundation is treated as a dwelling or ADU under Zoning Ordinance 18.78.340; a movable tiny home on wheels is regulated as a recreational vehicle and cannot be used as a permanent residence outside approved parks.

Political signs in unincorporated Inyo County are regulated under Title 18 Chapter 18.75 (Signs), which controls sign type, size, height, and placement by zone district. Along state highways, California's Outdoor Advertising Act (Bus. & Prof. Code 5405.3) caps temporary political signs at 32 sq ft, posted no sooner than 90 days before an election and removed within 10 days after.

Garage sale and other temporary signs in unincorporated Inyo County are regulated under Title 18 Chapter 18.75 (Signs), which sets permitted signs, sizes, and heights by zone. Off-premise signs in or near state highway right-of-way are separately restricted by Caltrans under the State Outdoor Advertising Act.

After a multi-year effort to protect the Eastern Sierra's dark skies, Inyo County adopted an Outdoor Lighting ordinance now codified as Title 18 Chapter 18.74. Reported standards cap unshielded fixtures at 100 lumens, require shielding for fixtures up to 600 lumens, and limit up-lighting to 3,000 kelvin to reduce glare, light trespass, and light pollution.

Inyo County's Outdoor Lighting ordinance (Title 18 Chapter 18.74) requires exterior lighting to be installed so as to prevent light trespass, glare, and light pollution. The County may require a problematic light to be shielded, filtered, redirected, or replaced, and limits flag lighting to the area of the flag without trespass.

Inyo County's published park and campground regulations set camping and use rules rather than a posted closing-hour curfew. County campgrounds are open year-round; camping is limited to 15 days at any one campground in any six-week period, fees are $14 per night, and firearms are prohibited. No specific overnight park-closure curfew is stated in the County's published park rules.
