Moving to Honolulu, HI?
Here are the local rules you need to know before you unpack.
Every city has its own set of local ordinances that go beyond state and federal law. From when you can mow your lawn to whether you can park your RV in the driveway, these rules affect daily life in ways most people do not expect. This guide covers the key ordinances in Honolulu across 30 categories and 126 specific rules we track.
🔊 Noise Ordinances
Noise rules affect everything from weekend parties to lawn care schedules. Quiet hours, construction restrictions, and barking dog limits vary widely between cities.
Construction Hours
Some RestrictionsHonolulu prohibits construction noise in residential zones outside permitted daytime hours. Work is generally allowed weekdays 7 AM–6 PM and Saturdays 9 AM–6 PM; no construction on Sundays or holidays without a variance.
Barking Dogs
Some RestrictionsHonolulu prohibits animal noise that disturbs neighbors continuously for 10 minutes or intermittently for 30 minutes or more at any time of day or night, under ROH Chapter 12, Article 2.
Amplified Music & Events
Some RestrictionsHonolulu prohibits playing or operating any sound-reproducing device on public property or in motor vehicles on public streets if the sound is audible at 30 feet from the device. A separate permit is required for mobile sound vehicles.
Leaf Blower Rules
Some RestrictionsHawaii state law (HRS § 342F-30.8) restricts leaf blower use near residential zones. Honolulu has no stricter local ordinance; the state statute controls hours of operation and fines.
Quiet Hours
Some RestrictionsHonolulu prohibits excessive noise under ROH Chapter 41, Article 6. Quiet hours run 10 PM–7 AM on weekdays and 10 PM–9 AM on weekends and holidays. Construction noise is capped at 55 dBA in residential zones during daytime hours.
🏠 Short-Term Rentals
If you plan to rent out your home on Airbnb or VRBO - even occasionally - you need to know the local STR rules before listing.
Primary-Residence-Only Rule
Heavy RestrictionsHonolulu Bill 41 (Ord. 22-7, effective October 2022) restricts short-term rentals under 90 days in residential zones to operators using the dwelling as their primary residence, outside the Waikiki resort district.
Host Presence Rule
Heavy RestrictionsBed-and-breakfast home registrations on Oahu require the operator to live on site during guest stays, distinguishing them from unhosted transient vacation units that demand a nonconforming use certificate.
Occupancy Limits
Heavy RestrictionsRegistered short-term rentals on Oahu cap overnight occupancy at two adults per bedroom plus two additional adults per dwelling, with infants under two not counted toward the limit.
Host Platform Liability
Heavy RestrictionsBill 41 imposes liability on Airbnb, VRBO, and similar booking platforms that list unpermitted Honolulu short-term rentals, requiring registration verification and quarterly data reporting to DPP.
Repeat Violator Strikes
Heavy RestrictionsHonolulu DPP escalates short-term rental enforcement through a three-strike framework, revoking registrations after repeat violations within a 24-month window and barring re-registration for two years.
Taxes & Fees
Heavy RestrictionsHonolulu requires transient vacation unit operators to register and pay a 3% county transient accommodations tax on top of state GET and TAT, plus annual registration fees. Non-resort-zone STRs are banned entirely.
Parking Rules
Heavy RestrictionsHonolulu's Land Use Ordinance requires short-term rental operators to submit a parking plan and prohibits guests of nonconforming-use TVUs and B&Bs in residential zones from parking on public streets near the unit.
Permit Requirements
Heavy RestrictionsHonolulu restricts short-term rentals (under 30 consecutive days) to resort-zoned areas and select apartment districts. All operators must obtain an annual registration certificate from the Department of Planning and Permitting before advertising or renting.
Noise Rules
Heavy RestrictionsHonolulu requires registered short-term rental hosts to post and enforce quiet hours from 10 PM to 7 AM under Ordinance 22-007. Violations may result in permit revocation and steep per-day fines.
Insurance Requirements
Heavy RestrictionsHonolulu requires every owner or operator of a transient vacation unit (TVU) or bed-and-breakfast home to maintain at least $1,000,000 per occurrence in commercial general liability coverage, or homeowner's insurance with business liability coverage (umbrella policies may be combined to reach the limit), under Revised Ordinances of Honolulu (ROH) §21-5.730 as amended by Ordinance 22-7 (Bill 41, CD2). Proof of coverage must be filed with the Department of Planning and Permitting (DPP) at registration and at every annual renewal, and a hosting-platform policy may satisfy the requirement only if it meets the minimum.
🔥 Fire Regulations
Fire pit rules, fireworks restrictions, and brush clearance requirements are especially important if you are coming from a state with different fire risk profiles.
Wildfire Zones
Heavy RestrictionsHawaii's 2023 Lahaina fire pushed Oahu to expand wildfire-hazard mapping, defensible-space outreach, and coordinated response between HFD, the Department of Land and Natural Resources, and DPP for leeward and high-risk slopes.
Propane Storage
Some RestrictionsHonolulu adopts the International Fire Code through ROH Chapter 11, capping residential propane container size and requiring placement that respects setbacks from buildings, ignition sources, and property lines, with HFD inspecting larger installations.
Fire Pit Rules
Heavy RestrictionsHonolulu regulates open burning under ROH Chapter 20 (Fire Code). Recreational, decorative, or ceremonial fires require prior written permission from the property owner and advance HFD approval; all fires must be reported to dispatch before ignition.
Fireworks
Heavy RestrictionsHonolulu bans virtually all consumer fireworks including sparklers, fountains, and aerial devices. Only licensed firecrackers with a permit are allowed on designated holidays. Violations carry heavy fines and potential imprisonment under ROH Chapter 20 and Hawaii state law.
Outdoor Burning
Heavy RestrictionsHonolulu regulates open outdoor burning under ROH Chapter 20 (Fire Code). Most open burning requires prior notification or written AHJ approval, and is prohibited when deemed a fire hazard.
Brush Clearance
Heavy RestrictionsHonolulu's Fire Code requires property owners in hazardous fire areas to maintain a 30-foot defensible space around structures by removing flammable vegetation and combustible growth at all times.
🚗 Parking Rules
Parking rules catch more new residents off guard than almost any other ordinance. RV storage, overnight parking bans, and driveway regulations vary significantly.
Commercial Vehicle Restrictions
Heavy RestrictionsHonolulu prohibits buses, trucks, vans, trailers, and other commercial vehicles with a gross weight of 10,000 pounds or more, or longer than 20 feet, from being stored or parked on any public street citywide without a permit or exception.
Driveway Rules
Some RestrictionsHonolulu's Traffic Code prohibits stopping, standing, or parking in front of, or within 4 feet of either side of, any public or private driveway. Violations bring mandatory citations and towing when access is blocked.
Street Parking Limits
Some RestrictionsHonolulu's Traffic Code (ROH Ch. 15) prohibits parking in specified locations without signs and sets metered time limits and tow-away zones. Fines start at $35 with escalation for each additional hour of violation.
RV & Boat Parking
Some RestrictionsHonolulu ROH § 15-16.6 prohibits buses, trucks, trailers, house trailers, and oversized vehicles (10,000 lb GVW or 20 ft or longer) from parking on any public street for more than four consecutive hours.
🧱 Fence Regulations
Planning to put up a fence? Height limits, material restrictions, and permit requirements differ by city - and sometimes by which side of the property the fence sits on.
Permit Requirements
Some RestrictionsIn Honolulu, fences six feet or under are generally exempt from building permits unless on a street corner or in a flood zone. Fences taller than six feet require a permit and fire-department access approval.
Height Limits
Some RestrictionsHonolulu's Land Use Ordinance limits residential fences to 6 feet in side and rear yards and 4 feet in front yards. Fences over 6 feet require a Department of Planning and Permitting building permit.
Neighbor Fence Rules
Some RestrictionsHonolulu's Land Use Ordinance (ROH Chapter 21) limits fences and walls to 6 feet in required yards. Fences taller than 6 feet or new fences costing over $1,000 require a building permit; shared boundary-line fences involve mutual consent and state cost-sharing law.
Material Restrictions
Some RestrictionsHonolulu regulates fence materials through its Building Code (ROH Chapter 16) and Land Use Ordinance (ROH Chapter 21). Fences up to 6 feet using permanent materials are generally permit-exempt. Barbed and razor wire are prohibited on most residential and commercial fences.
🐔 Animal Ordinances
Pet owners and aspiring chicken keepers should check local animal ordinances before signing a lease or closing on a home.
Exotic Pets
Heavy RestrictionsHawaii bans most exotic pets statewide to protect fragile island ecosystems. Honolulu residents cannot keep snakes, ferrets, hamsters, gerbils, or most reptiles. State quarantine and import permits are required for legal pets entering the islands.
Wildlife Feeding
Some RestrictionsHonolulu and Hawaii law restrict feeding feral cats, chickens, monk seals, sea turtles, and nene geese. Intentional feeding that harms protected species or creates nuisances on public property can trigger civil and criminal penalties.
Cat Rules
Some RestrictionsHonolulu does not require cat licensing but enforces leash-or-confinement expectations through nuisance provisions. Cats damaging neighbor property or harming protected wildlife can trigger citations, and the Hawaiian Humane Society manages island-wide TNRM colony registration.
Pet Limits
Few RestrictionsHonolulu does not impose a strict numeric pet limit but uses nuisance and zoning ordinances to address situations where multiple animals create complaints. Kennel-level operations require permits under ROH Chapter 21 zoning rules.
Microchipping
Few RestrictionsHonolulu does not legally mandate microchipping for owned pets, but the Hawaiian Humane Society chips every adopted animal and the state's quarantine program treats microchips as essential proof of identity for direct-airport-release dogs and cats.
Beekeeping
Some RestrictionsHonolulu allows noncommercial beekeeping on any zoning lot of at least 5,000 sq ft. Hive numbers are capped by lot size, all colonies must be in movable-frame hives, and a 25-foot setback from property lines is required unless a flyway barrier is used.
Chickens & Livestock
Heavy RestrictionsHonolulu caps chickens and peafowl at two per household and prohibits farm animal enclosures within 300 feet of a property line, effectively barring most livestock in dense residential areas.
Breed Restrictions
Few RestrictionsHonolulu has no breed-specific legislation. Dangerous-dog rules under ROH Chapter 12, Article 7 are based solely on individual dog behavior, not breed. Any dog that attacks without provocation may be declared dangerous.
Dog Leash Laws
Some RestrictionsHonolulu requires dogs to be on a leash no longer than 6 feet whenever off the owner's premises, under ROH Chapter 12, Article 4. Designated off-leash parks are permitted by the Department of Parks and Recreation.
🌿 Landscaping Rules
From grass height limits to tree removal permits, landscaping rules can surprise new homeowners, especially in drought-prone areas with water restrictions.
Grass Height Limits
Some RestrictionsHonolulu requires property owners to keep their land free of excessive weeds, overgrown grass, and waste. Uncultivated flammable weeds exceeding 18 inches within 30 feet of a building in residential or apartment zones are defined as a public nuisance.
Water Restrictions
Some RestrictionsHonolulu's Board of Water Supply (BWS) may declare mandatory water-conservation stages restricting outdoor irrigation timing and volume. The Land Use Ordinance also requires permanent irrigation systems for required landscaping on development sites.
Weed Ordinances
Some RestrictionsHonolulu's ROH Chapter 41, Article 10 requires property owners to cut and remove weeds and waste that constitute a public nuisance. Owners have 30 days to comply before the city abates at owner's expense.
Tree Trimming
Some RestrictionsHonolulu requires permits for trimming, pruning, or removing street trees in the public right-of-way (ROH § 10-1.4) and for any work on city-designated exceptional trees under ROH Ch. 40, Art. 8. Fines up to $1,000 apply for violations.
Tree Removal & Heritage Trees
Heavy RestrictionsHonolulu protects designated 'exceptional trees' under Revised Ordinances of Honolulu (ROH) Chapter 40, Article 8. Removing or destroying any exceptional tree without City Council approval is unlawful (ROH § 40-8.8). Any pruning of branches or alteration of an exceptional tree's characteristic shape requires a permit from the Department of Parks and Recreation (Division of Urban Forestry). Street trees in the public right-of-way are City property and always require a permit.
💼 Home Business
Working from home is common, but running a business from home often requires permits and must comply with zoning restrictions on customer traffic and signage.
Signage Rules
Heavy RestrictionsHonolulu's Land Use Ordinance prohibits any exterior signage indicating a home is used for a business. Under ROH § 21-5.350, home occupations must be invisible from the street — no signs, displays, or advertising may be mounted on or near the dwelling.
Zoning Restrictions
Some RestrictionsROH Chapter 21, §21-5.350 permits home occupations as accessory residential uses, provided the business is incidental to the dwelling, employs only household members, has no exterior signage, and does not alter the home's residential character.
Customer Traffic Restrictions
Some RestrictionsHonolulu allows home occupations with customer or client visits as an accessory residential use, but requires one off-street parking space per five clients and prohibits on-street commercial vehicle parking.
🏊 Swimming Pools & Spas
Pool ownership comes with safety fencing requirements, permit obligations, and drainage rules that vary by jurisdiction.
Pool Permits
Some RestrictionsA building permit from the Honolulu Department of Planning and Permitting is required before constructing any residential swimming pool, under ROH Chapter 16, Article 6. Plans must be prepared by a licensed Hawaii engineer or architect.
Fencing Requirements
Heavy RestrictionsHonolulu ROH § 16-6.2 requires all residential swimming pools to be enclosed by a barrier at least 48 inches high with self-closing, self-latching gates. The building code adopts ISPSC standards for gap clearance and non-climbable design.
Safety Rules
Heavy RestrictionsHonolulu requires all residential swimming pools to be enclosed by a barrier at least 48 inches high with self-closing, self-latching gates. A building permit is required before construction. Non-compliant pools face penalties under ROH Chapter 16.
Above-Ground Pools
Some RestrictionsHonolulu treats above-ground pools the same as in-ground pools for safety. Under ROH Chapter 16, which adopts the Hawaii State Residential Code (IRC) and Hawaii Building Code Section 3109, any residential pool capable of holding more than 24 inches of water must be enclosed by a 48-inch barrier, with openings that block a 4-inch sphere, self-closing/self-latching gates, and only a 4-inch maximum gap between the pool wall and the barrier when the pool wall itself is used as the enclosure. Ladders or steps must be removable, lockable, or independently fenced. A building permit from DPP is required before installation of any pool deeper than 24 inches.
🏗️ Accessory Structures
Thinking about an ADU, shed, or garage conversion? Local rules on accessory structures have changed rapidly in recent years, especially in California.
Shed Rules
Few RestrictionsHonolulu allows one-story detached storage sheds of up to 120 square feet on residential lots without a building permit under ROH Ch. 18. Larger structures require a building permit and must conform to zoning setbacks under ROH Ch. 21.
Garage Conversions
Some RestrictionsHonolulu's LUO § 21-5.720 allows garage and accessory structure conversions into accessory dwelling units in residential zones, subject to floor area limits, parking requirements, and a building permit from DPP.
ADU Rules
Some RestrictionsHonolulu allows one accessory dwelling unit on residential lots of 3,500 sq ft or more. Size is capped at 400–800 sq ft depending on lot size. Owner must live on the property and ADUs may only be rented long-term (six-month minimum).
Carport Rules
Some RestrictionsHonolulu carports must meet the same Land Use Ordinance (LUO) yard setbacks as the main house unless the homeowner obtains a Zoning Adjustment under ROH §21-2.140-1. A one- or two-car carport may encroach into required front and side yards only if no other viable alternative exists relative to a dwelling legally built before October 22, 1986, or to lot topography, and the carport's horizontal footprint generally cannot exceed 20 feet by 20 feet. A DPP building permit under ROH Chapter 16 is required, and carports do not count as floor area for FAR purposes.
ADU Rental Restrictions
Heavy RestrictionsHonolulu prohibits short-term rentals (under 90 days outside resort districts, under 30 days in resort districts) of Bill 7 ADUs under both the recorded long-term rental covenant in LUO Sec. 21-5.730 and Bill 89 (2019) / Bill 41 (2022) STR enforcement. ADUs must be rented for 180 days or longer per the recorded covenant. Hawaii state General Excise Tax (GET) and Transient Accommodations Tax (TAT) apply to rentals.
ADU Permits
Some RestrictionsHonolulu City and County recognizes two distinct accessory residential units under the Land Use Ordinance (LUO) Chapter 21: the traditional Ohana Dwelling Unit (LUO Sec. 21-5.700) and the Accessory Dwelling Unit (ADU) created by Bill 7 (2015) under LUO Sec. 21-5.730. Both require a building permit through the Department of Planning and Permitting (DPP). Lot size, infrastructure, and zoning eligibility differ between the two.
ADU Impact Fees
Some RestrictionsHonolulu does not impose a dedicated ADU impact fee, but Board of Water Supply (BWS) Water System Facilities Charges and Department of Facility Maintenance sewer assessment fees commonly add several thousand dollars per ADU. Standard DPP building permit fees scale to construction valuation. Bill 7 ADU applicants also pay a per-unit infrastructure assessment.
ADU Owner Occupancy
Some RestrictionsBill 7 ADUs in Honolulu (LUO Sec. 21-5.730) require a recorded covenant restricting use to long-term residential rental (180+ day leases) but do not require owner occupancy of the principal dwelling. Traditional Ohana units (LUO Sec. 21-5.700) historically were intended for extended family but the LUO does not impose a formal owner-occupancy mandate on Ohana units either.
🍖 Outdoor Cooking
Smoker Rules
Few RestrictionsHonolulu has no smoker-specific ordinance. Hawaii Department of Health air pollution rules under HAR Chapter 11-60.1 apply to large commercial sources, not residential smokers. ROH Sec. 41-8 prohibits open burning without permit but enclosed pellet, electric, and offset smokers are exempt. HOA covenants under HRS 421J / 514B may restrict smokers. Dense leeward neighborhoods generate occasional nuisance smoke complaints.
BBQ & Propane Rules
Some RestrictionsHonolulu Fire Code (ROH Chapter 20) adopts the International Fire Code with Hawaii amendments. IFC Section 308.1.4 restricts open-flame cooking and LP-gas containers over 1 lb on combustible balconies of buildings with three or more units. Charcoal grills must be 10 feet from combustible buildings. Honolulu Fire Department enforces. Outdoor cooking is otherwise widely permitted in single-family yards.
Outdoor Kitchen Permits
Some RestrictionsHonolulu requires DPP building permits for outdoor kitchens with gas line plumbing, electrical wiring, plumbing fixtures, or structural roofs/pergolas. Standalone freestanding BBQs require no permit. Trade permits are filed through Honolulu ePlans. Special Management Area (SMA) coastal properties may require additional SMA approval under HRS Chapter 205A.
🎄 Holiday Decorations
Lawn Ornament Rules
Few RestrictionsHonolulu has no city ordinance restricting lawn ornaments on residential property. HOA and condo covenants under HRS 421J and 514B commonly regulate ornaments through CC&Rs and architectural review. Historic district properties (Chinatown, Hawaii Capital) may have appearance review. Religious displays receive some federal Fair Housing Act protection. SMA shoreline properties may have additional review.
Inflatable Display Rules
Few RestrictionsHonolulu has no city ordinance regulating residential inflatable holiday displays. Size and blower noise are governed by HOA and condo covenants under HRS 421J and 514B. Honolulu noise rules (HAR Chapter 11-46) regulate excessive noise but rarely target seasonal blowers. High-rise condos generally prohibit inflatables on lanais. Single-family lots in Mililani, Hawaii Kai, and Kaneohe commonly display inflatables.
Holiday Light Rules
Few RestrictionsHonolulu has no municipal ordinance regulating residential holiday lights. Display timing, brightness, and animation are governed by HOA and condo covenants under HRS Chapter 421J (community associations) and HRS Chapter 514B (condominiums). Many high-rise condos restrict lights on lanais visible from the exterior. Honolulu City Lights downtown display is a city program, not a regulation.
🌍 Environmental Rules
Coastal Development
Heavy RestrictionsMost development within Honolulu's Special Management Area (SMA) along Oahu's shoreline requires a special permit reviewed by DPP under HRS chapter 205A and ROH chapter 25.
Flood Zones
Heavy RestrictionsHonolulu enforces FEMA flood zone construction standards under ROH chapter 21A and uses the city's Sea Level Rise Vulnerability Viewer to guide permits in low-lying coastal neighborhoods.
Stormwater Management
Some RestrictionsHonolulu's storm drain system discharges directly to the ocean, so ROH chapter 14 article 12 prohibits non-stormwater discharges and requires best management practices on construction and industrial sites.

Buffer Zones
Heavy RestrictionsHawaiʻi state law sets a 750-foot buffer between any cannabis dispensary and schools, playgrounds, or public housing. Honolulu enforces this at the conditional-use permit stage under ROH Chapter 21.
🔑 Rental Property Rules
Rent Control
Few RestrictionsHawaii Revised Statutes section 521-12 partially preempts local rent control, leaving Honolulu without authority to cap residential rent increases except on county-administered affordable housing units and Hawaiian Home Lands.

Tree Removal Permits
Some RestrictionsTrees in the public right-of-way or in city parks belong to the City and County of Honolulu, and removal requires a permit and arborist review under ROH chapters 14 and 41.
Heritage & Protected Trees
Heavy RestrictionsHonolulu's Exceptional Tree Ordinance (ROH Chapter 41) protects individually designated specimens for age, rarity, size, historic, or aesthetic value. Designation is by City Council resolution after Outdoor Circle and Arborist Advisory Committee review. Removal or major pruning requires a permit and may require Council action; tax credits up to $3,000 incentivize care.
🔧 Building Safety
Pest Control
Some RestrictionsHawaii's tropical climate makes termite, cockroach, and rodent control central to building safety. Honolulu landlords must keep rentals habitable under HRS §521-42, and DOH enforces statewide vector control for mosquitoes and rats.
Elevator Maintenance
Heavy RestrictionsHawaii's Department of Labor Boiler and Elevator Branch regulates all passenger elevators, escalators, and lifts statewide. Honolulu condos and commercial buildings must obtain annual inspection certificates, posted in the cab, with violations triggering shutdown orders.

Fire Sprinkler Requirements
Heavy RestrictionsHonolulu requires fire sprinklers in new high-rise buildings and many commercial structures under ROH Chapter 11 and the International Fire Code. After deadly Marco Polo fire of 2017, retrofit incentives and disclosure rules expanded for older condominium towers.
Door Locking Hardware
Some RestrictionsHonolulu's adopted IBC and IFC, layered on Hawaii landlord-tenant law, require functioning locks, single-action egress hardware, and accessible exits. Smart-lock and keyless retrofits must still meet emergency-exit and ADA requirements.
Green Building Code
Some RestrictionsHonolulu adopts updated International Energy Conservation Code provisions and city sustainability ordinances tied to its Climate Action Plan. New construction and major remodels must meet insulation, cool-roof, and EV-ready standards alongside Hawaii's clean-energy mandates.
🚬 Tobacco & Vaping
Tobacco Age Restrictions
Heavy RestrictionsHawaiʻi was the first US state to raise the tobacco purchase age to 21, effective January 2016 under HRS §709-908. The law covers cigarettes, cigars, e-cigarettes, vapes, and all nicotine products.
Vape Retail Rules
Some RestrictionsVape and e-cigarette retailers on Oʻahu must register with Hawaiʻi DOH, comply with Tobacco 21, and observe ROH Chapter 41 smoke-free rules prohibiting vaping in enclosed public places and workplaces.
Flavored Tobacco Bans
Some RestrictionsHawaiʻi has not yet enacted a comprehensive statewide flavored-tobacco ban, but Honolulu enforces FDA federal flavored-cigarette restrictions and state law prohibits flavored vape sales to minors aggressively.
🛍️ Single-Use Items
Plastic Bag Rules

Plastic Straw Rules
Some RestrictionsPlastic straws fall under Honolulu's disposable foodware ordinance: vendors may only provide them on request, and many establishments have transitioned to paper or compostable straws to comply.
💼 Employment Preemption
Minimum Wage Preemption
Heavy RestrictionsHawaiʻi sets a single statewide minimum wage and bars Honolulu and the other counties from enacting higher local floors, with the rate scheduled to climb from $14.00 in 2026 to $18.00 by January 1, 2028.
Paid Leave Preemption
Few RestrictionsHawaiʻi has no statewide paid family or sick leave statute; workers rely on the federal FMLA, the state Family Leave Law (unpaid), and Temporary Disability Insurance for short-term medical events under HRS §392.
Worker Scheduling Preemption
Few RestrictionsHonolulu and Hawaiʻi do not require advance schedule notice, predictability pay, or fair workweek protections, so retail and fast-food employers may set or change shifts without the penalties imposed in Seattle, San Francisco, and New York.
🛂 Immigration Policy
Sanctuary Policy Preemption
Some RestrictionsHonolulu adopted Resolution 17-78 declaring itself a Welcoming City and Hawaiʻi limits state and local cooperation with federal civil immigration enforcement under HRS §28-12, though the framework stops short of a full sanctuary statute.
E-Verify Mandates
Few RestrictionsHawaiʻi does not require private employers to use the federal E-Verify system, and Honolulu has no city ordinance imposing electronic employment verification, leaving compliance with federal Form I-9 as the only universal hiring obligation.
🛏️ Homelessness & Encampment Rules
Sit-Lie Rules

Hotel Worker Retention
Some RestrictionsHawaiʻi enacted Act 1 (2021) requiring hotels and similar hospitality employers to recall laid-off workers by seniority when positions reopen, protecting Honolulu's tourism workforce from displacement after pandemic-era layoffs and ownership changes.
Hotel Living Wage
