Hawaii’s 20-Foot Smoking Law: Zones, Vapes, and Penalties

Hawaii’s 20-foot smoking law prohibits lighting up within 20 feet of any entrance, exit, operable window, or ventilation intake of a building where indoor smoking is banned. The rule lives in Hawaii Revised Statutes Section 328J-6, and it covers traditional tobacco products and electronic smoking devices alike.¹ A smoker caught inside that buffer faces a fine of up to $50; a business that fails to enforce it faces up to $500 per violation, with each day counting separately.²

What the 20-Foot Rule Actually Says

Section 328J-6 calls 20 feet a “presumptively reasonable minimum distance.” That phrasing is doing real work. Twenty feet is the default distance you must keep from a covered building’s doorways, operable windows, and vents, and in practice it is the number everyone enforces to.¹

A property owner who thinks a shorter distance would still keep smoke out of the building can petition the Department of Health to argue the point. The owner has to prove by clear and convincing evidence that the building’s layout and ventilation would stop smoke from drifting inside at a shorter distance.¹ The bar is high and the process is demanding, so almost every building in Hawaii enforces the full 20 feet.

If you can see a door, an openable window, or a ventilation vent within roughly 20 feet, you are too close. Walk further out before you light up.

Where the Buffer Zone Applies

The 20-foot rule attaches to any building where Chapter 328J bans indoor smoking, and that covers most of Hawaii. Smoking is prohibited inside:

Enclosed or partially enclosed areas of buildings and vehicles owned, leased, or operated by the state or counties.³
Enclosed or partially enclosed public places open to the public, including restaurants, bars, shopping centers, airports, museums, libraries, and elevators.⁴
Enclosed or partially enclosed workplaces, whether or not the public has access.⁵
Enclosed or partially enclosed areas of stadiums, arenas, and amphitheaters.⁶

If smoking is banned inside the building, the buffer applies outside it. Hotels, hospitals, government offices, retail shops, bars, and restaurants all qualify. The entrance to a shopping mall, the sliding doors of a hotel lobby, a hospital’s covered driveway, the back door of a restaurant where staff take breaks: each one carries its own 20-foot radius.

Every covered location also has to post signs reading “Smoking Prohibited by Law” with letters at least an inch tall, or the international no-smoking symbol.⁷ Absence of a sign is not a defense; the ban applies regardless.

Vapes and E-Cigarettes Count

Chapter 328J defines “smoking” broadly. The term covers lighting, inhaling, or carrying any tobacco or plant product meant for inhalation, and the definition explicitly includes electronic smoking devices.⁸ A vape pen, an e-cigarette, a cigar, and a pipe are all treated the same way as a cigarette for purposes of the indoor ban and the 20-foot buffer.

Medical cannabis cardholders are not exempt either. Smoking cannabis is prohibited in every space Chapter 328J covers.

Penalties

Hawaii treats individual smokers and the businesses responsible for enforcement differently.

If You Are the Smoker

A person who smokes in a prohibited area, including inside the 20-foot buffer, faces a fine of up to $50 per violation.² The statute does not escalate the amount for repeat individual offenders. A police officer who issues a citation can also physically remove you from the premises if you refuse to put the cigarette or vape out.

Ignoring the citation makes things worse. Failing to appear at the time and place specified adds a $25 fee, and the court can eventually issue a warrant.²

If You Own or Run the Building

Owners, managers, and operators of covered places face escalating fines for failing to comply, whether the problem is missing signage, letting smokers linger inside the buffer, or allowing indoor smoking:²

Up to $100 for a first violation.
Up to $200 for a second violation within one year.
Up to $500 for each additional violation within the same year.

Each day of continued noncompliance counts as a separate violation, so fines stack fast. A business that keeps ignoring the law also risks suspension or revocation of its permits and licenses.² The Department of Health has primary jurisdiction, with police issuing citations on the ground.⁹

Exceptions

Section 328J-7 lists a handful of places exempt from the indoor bans, though the 20-foot buffer around their entrances and vents still applies:¹⁰

Private residences, unless being used as a licensed childcare, adult day care, or healthcare facility.
Designated smoking rooms in hotels and motels, capped at 20 percent of guest rooms, grouped together on the same floor, with no smoke migration to non-smoking areas. Once a room is converted to non-smoking, the change is permanent.
Retail tobacco stores, provided smoke does not reach prohibited areas.
Private or semi-private rooms in nursing homes and long-term care facilities, but only when every occupant is a smoker and has made a written request.
Outdoor portions of workplaces, unless they also qualify as public places or sports venues.
Active film production sets.
Designated outdoor smoking areas at state correctional facilities, limited to employees and volunteers, outside any area inmates can access.

The hotel exception confuses visitors most often. A hotel with smoking rooms has not opened its lobby, hallways, pool deck, or balconies to smoking. The exception covers the designated rooms and nothing else, and the 20-foot buffer still protects every entrance.

Where the 20-Foot Rule Does Not Reach

Chapter 328J is built around enclosed and partially enclosed buildings and the buffers around them. Smoking bans at Hawaii’s beaches and parks come from different statutes. State parks and beaches fall under HRS Section 184-4.5, and the four counties (Hawaii, Maui, Honolulu, and Kauai) each have their own park ordinances. Kauai’s county coverage applies to specific locations rather than every county park. In practice, assume smoking is prohibited at any public beach or park in the state, but understand the citation and fine will come under those statutes, not under Chapter 328J.

Federal land is a separate layer. On National Park Service property in Hawaii, smoking is banned inside all NPS buildings and vehicles and within 25 feet of any public entrance or exit, and park superintendents can expand that further.¹¹ The federal distance is 25 feet, five more than the state buffer, so give federal buildings a wider berth.
