Oahu’s Rental Rules: Can You Still Own a Vacation Rental Condo?
Yes, but only in certain buildings, and fewer than most buyers expect. On Oahu, rentals under 30 days are legal mainly in resort-zoned areas or in units that hold a nonconforming use certificate. Everywhere else, you’re looking at monthly or longer tenants.
The rules in plain terms
Honolulu’s current rules come from Ordinance 25-2, which took effect September 30, 2025. Here’s how rental lengths break down:
| Rental length | Where it’s allowed |
|---|---|
| Under 30 days | Resort-zoned areas, or units with a valid nonconforming use certificate (NUC). Must be registered with the city. |
| 30 to 89 days | Units that were already renting this way on or before October 23, 2022. |
| 90 days or more | Generally allowed as a regular long-term rental. |
The 30-to-89-day row is the confusing one. In 2022 the city tried to raise the minimum stay everywhere outside resort areas from 30 to 90 days. A federal court blocked that for owners who were already renting before October 23, 2022. If you buy now, assume you’ll need 90-day tenants unless the unit is in a resort zone or has an NUC. Confirm the specific unit with the Department of Planning and Permitting before you rely on anything shorter.
Where vacation rentals work
Waikiki is where most legal vacation rental condos are. Even there, it depends on the building. One local brokerage counted about 30 of roughly 130 Waikiki condo buildings that allow short-term rentals. The rest are zoned for apartments or have house rules that require 30-day minimums.
A Waikiki condo can usually rent nightly in one of three ways:
- It’s in the Resort Mixed Use precinct, and the building’s own rules allow it.
- The unit has its own NUC.
- The building has grandfathered hotel status, and its rules allow it.
Outside Waikiki, resort areas like Ko Olina and Turtle Bay have their own zoning and association rules. Check each project individually.
What to check before you buy
- Zoning and house rules. When the city allows something and the building doesn’t, the stricter rule wins. Read the bylaws and house rules, not just the listing.
- NUC status. An NUC has to be renewed every year. If an owner let it lapse, it’s gone for good and can’t be reissued. Ask for proof that it’s current.
- Registration. Some registrations belong to the owner, not the unit, and don’t transfer when you buy. Ask what happens to it at closing.
- Financing. Many condotel units don’t qualify for regular loans. Expect a portfolio loan with a larger down payment, often around 30%. Lenders may also require a full kitchen.
- Management costs. A hotel rental program can take half or more of gross rent. Independent managers often charge 15% to 25%.
- A local contact. If you live off-island, Hawaii law requires you to name someone on Oahu to handle your rental.
Penalties are real
The city does enforce. An illegal short-term rental can draw a $1,000 fine plus $5,000 per day for a first violation, and $10,000 plus $10,000 per day for repeat violations.
Rules could still change
A 2024 state law, Act 17, gave counties the power to phase out vacation rentals outside resort areas. Maui is already doing it. Honolulu’s current ordinance doesn’t set a phase-out schedule, but that could change. If you’re buying mainly for rental income, a resort-zoned building is the safer bet.
Next step
If you’re looking at a specific building, send it over. We’ll check its zoning, house rules, and rental history before you make an offer.
