Is short-term rental legal in Honolulu (Oahu), HI?
Oahu's Ordinance 22-7 confines legal STRs (under 30 days) to resort zones and specific apartment precincts. Outside them, the lawful categories are narrow: registered bed-and-breakfast homes (host on site, max 2 rooms) — and very few nonconforming-use certificates survive from before 1989.

| What counts as a short-term rental | Oahu's Ordinance 22-7 confines legal STRs (under 30 days) to resort zones and specific apartment precincts. Outside them, the lawful categories are narrow: registered bed-and-breakfast homes (host on site, max 2 rooms) — and very few nonconforming-use certificates survive from before 1989. |
|---|---|
| Permit / license | Registration (resort/apartment zones) or Bed-and-Breakfast Home registration; NUC for pre-1989 units — issued by Honolulu Department of Planning and Permitting (DPP) |
| Fee | Registration fees run a few hundred dollars; the fines dwarf them |
| Renewal | Annual renewal with display of the registration number in every ad |
| Primary-residence rule | B&B homes require the proprietor living on site; resort-zone units follow their district rules. |
| Whole-home rental | Outside resort zones and the listed apartment precincts, whole-home rentals under 30 days are prohibited — the minimum lawful rental in residential zones is 30 days (Bill 41 framework; enforcement provisions have been litigated — checked October 2026). |
| Night cap | — |
| Guests / occupancy | B&B: max 2 rooms / 4 guests |
| Minimum stay | 30 days outside resort/apartment zones |
| Zoning | Resort zones + named apartment precincts are the map; everything else residential is 30-day minimum territory. |
| Density / scarcity | No density cap found in the current rules |
| Fines | Fines up to $10,000 per day for illegal rentals — among the highest per-day schedules in the country |
| Taxes | Hawaii GET + TAT registration (state tax ID) is required before listing; platforms do not replace the state registration. |
| Platform duties | Ads must display the registration/NUC number; platforms face duties under the ordinance. |
| State layer | No state preemption — counties are the regulators, and Hawaii's counties run some of the strictest regimes in the US (resort-zone-only rules in Honolulu, a legislated phase-out on Maui). |
What trips hosts in Honolulu (Oahu)
- Honolulu's $10,000/day fine is real and assessed; 'everyone does it' is the most expensive sentence on Oahu.
- The 30-day line means a 29-night booking is an STR and a 30-night booking is a tenancy — the calendar is a legal document here.
The private layer still applies
These are the city's rules. Your HOA, condo board, lease or mortgage can say no on top of them — that layer is printed as a warning in the checker, never merged into the city's verdict.
