Investment Property Loans in Honolulu, HI

Apart from grandfathered permits, Oahu rentals under 30 consecutive days are allowed only in resort-zoned areas and the apartment-zoned areas mapped in Ordinance 25-52; elsewhere a home must rent for 30 days or longer.

For investors: Check the city's STR eligibility map before paying a resort-condo premium; a written zoning verification costs $300. Ordinance 22-7 set a 90-day minimum, but the department says it enforces the 30-day line across the board.

Each eligible Honolulu short-term rental unit must be registered separately and renewed every year, and any change of owner or operator requires a brand-new registration.

For investors: A buyer of a registered resort-zone condo cannot simply take over the seller's registration, so plan for a gap before nightly income resumes. Ads for stays under 30 days must show the registration or NUC number plus the tax map key from the tax bill.

Honolulu's grandfathered vacation rentals run on Nonconforming Use Certificates for operations dating from before October 22, 1986; no new ones are issued, and each must be renewed between September 1 and October 15 yearly.

For investors: Renewals not approved by October 15, 2026 expire automatically, and renewals now run through HNL Build with an occupancy record attached. A new owner may renew a certificate only before it lapses, so confirm renewal status in writing before closing on a NUC home.

Since Ordinance 22-7, an illegal Honolulu vacation rental faces an initial civil fine up to $10,000 and up to $10,000 a day while it continues; ads left up seven days after notice draw separate fines.

For investors: For ads the first fine is up to $5,000, then up to $10,000 for each further day online, and an unlawful listing counts as evidence the unit is operating. The ordinance's $1,000-to-$10,000 daily range applies to hosting platforms, not owners.

The Oahu Transient Accommodations Tax, created by Ordinance 21-33, has applied since December 14, 2021 at 3% of gross rental proceeds, collected by the city on top of the state's own taxes.

For investors: Since May 2026 the city has been mailing proposed assessments for the 2023 tax year, with 2024 and 2025 to follow, and owners have 30 days to pay or appeal. Annual OTAT reconciliations are due April 20, so keep gross booking records by unit.

Under Ordinance 22-6, anyone selling Oahu real property must give the buyer a short-term rental disclosure form, revised May 2025, stating whether the property can legally be used for short-term rentals.

For investors: Read the form before removing contingencies on any condo marketed with vacation-rental income. If it says no, underwrite on 30-day-plus rent only, and set aside any seller rent roll built on nightly stays.

Honolulu's Residential A class, homes with up to two units and condos worth $1 million or more with no home exemption, pays $4.00 per $1,000 on the first $1 million and $11.40 above for FY2027.

For investors: In the city's own example, a $1.6 million house owes $10,840 as Residential A versus $5,180 for an owner-occupant with the $120,000 home exemption at the $3.50 Residential rate. A rental has no home exemption, so budget the higher tier.

Honolulu's FY2027 Transient Vacation class pays $9.00 per $1,000 on the first $800,000 of value and $11.50 above, against $6.50 for bed and breakfast homes and $13.90 for hotel and resort.

For investors: A unit classed Transient Vacation pays well over double the $3.50 Residential rate, which eats into the nightly premium. Check the class on the assessment notice each December and appeal by the January 15 deadline if it looks wrong.

Updated FEMA flood maps for Oahu took effect June 10, 2026, after a 2019 to 2024 study, with Lāʻie, Kāneʻohe, Waiʻanae and East Honolulu among the most affected areas.

For investors: Owners newly placed in a high-risk zone face lender-required flood insurance and possible force-placed coverage after 45 days, and remodels may lose Quick Permit eligibility. Honolulu's Class 8 standing in FEMA's discount program trims flood premiums 10%.

Ordinance 25-2 caps an Oahu ADU at 500 square feet on lots under 5,000 square feet and 1,000 square feet on larger lots, and allows one per zoning lot, including lots with several existing units.

For investors: A recorded covenant keeps the ADU in long-term residential use, never a vacation rental, and bars selling it off as a condo. Its extra parking space is waived within half a mile of rail, or 800 feet of a bus stop in the Primary Urban Center and Ewa areas.

The University of Hawaiʻi at Mānoa, the oldest and largest of 10 UH campuses, enrolled 20,028 students in fall 2024, with 35% from out of state and 6% international.

For investors: Roughly 7,000 Mānoa students come from other states and arrive without local housing, which supports long-term leases near campus. Summer gaps cannot be filled with nightly guests outside resort zones, so plan around terms of 30 days or more.
