Honolulu, HI.

In-depth analysis

Should you buy an STR in Honolulu in 2026?

Only in resort-zoned property — or as a 90-day minimum-stay mid-term rental. Oahu’s STR market underwent the most dramatic regulatory tightening of any major U.S. market when Ordinance 22-7 took effect: short-term rentals (under 90 days) became illegal in almost every residential zone, with enforcement and fines stepped up materially. ADR sits at $258 and occupancy at 62% in legal product, with a market score of 58/100 reflecting the very thin slice of legal inventory.

Regulation: where the city stands

Ordinance 22-7 (City and County of Honolulu) reshaped the market entirely:

• 30-day minimum stay was extended to a 90-day minimum in most residential zones — effectively ending the traditional STR business model outside resort districts.
• Resort-zoned property (primarily Waikiki, parts of Ko Olina, and Turtle Bay) remains legally available for sub-30-day rental.
• Bed-and-breakfast (B&B) and Transient Vacation Unit (TVU) permits exist but are capped and largely closed to new entrants.
• Fines for non-compliant operation start at $10,000/day and have been actively enforced.

Litigation has resolved much of the ordinance in the city’s favor. The 90-day rule is the binding reality for buyers in 2026.

The market by the numbers

Source: AirDNA-comparable industry averages. The market for legal STR product is small and competitive; the broader Oahu housing market is a 90-day-minimum mid-term rental market for non-resort property.

Submarkets that matter

• Waikiki (resort-zoned) — highest legal STR density; condo-heavy; resort-management common; HOA permission required.
• Ko Olina / West Oahu resort district — newer resort inventory; family demand; strong ADR.
• Turtle Bay / North Shore resort area — small but premium resort-zoned inventory.
• Everywhere else (Kailua, Hawaii Kai, Manoa, Kaneohe, Aiea) — 90-day minimum. Operate as mid-term rental for traveling nurses, military, relocation; not as nightly Airbnb.

The 3 mistakes buyers make here

1. Buying residential-zoned product expecting nightly rental income. Pre-2022 listing language and Zillow descriptions are obsolete. The 90-day minimum is enforced.
2. Underwriting Waikiki ADR for a Ko Olina or Turtle Bay property. Different submarkets, different demand, different HOA structures.
3. Skipping the HOA letter. Many Waikiki towers have building-level STR bans — even within the resort zone — or strict registration. Get HOA permission in writing before closing.

What to do next

• Verify zoning with City and County of Honolulu Department of Planning and Permitting.
• Pull HOA bylaws and STR permission in writing before offer expires.
• Run Market Score and Comp Analyzer within the same resort district.
• If pivoting to 90-day mid-term: model with Cash-on-Cash Return Calculator at MTR ADR (~50-60% of nightly).
• Read Reading an STR Ordinance Before You Buy — Ord 22-7 is the textbook regulatory shift.
