Hawaiʻi Short-Term Rental Rules for Investors 2026

Hawaiʻi’s four counties have each taken their own approach to restricting short-term and vacation rentals over the past several years, and the differences between them are significant enough that a strategy which works on one island can be flatly unavailable on another. This guide walks through the general shape of the rules county by county and explains why this regulatory environment is reshaping exit strategy for investors across the state.

Why This Matters More Than Ever

Short-term rental policy in Hawaiʻi has moved fast, and it keeps moving. Counties have cited housing affordability pressure as the primary driver, arguing that converting long-term housing stock into nightly vacation rentals reduces the supply available to residents. Whatever the merits of that argument, the practical effect for investors is the same: an exit strategy or a rental income projection built on the assumption that a property can operate as a short-term rental needs far more diligence today than it did five years ago. This is true whether you’re buying to hold, buying to flip, or buying to build.

Oʻahu Short-Term Rental Rules: Resort Zone Concentration

The City and County of Honolulu has restricted short-term rental operation outside of resort-zoned areas under recent ordinances, generally limiting legal nightly rentals to properties within resort districts like Waikīkī, and to a small number of properties that hold a nonconforming use certificate predating the current rules. Outside those categories, operating a short-term rental on Oʻahu generally isn’t permitted, regardless of how a listing may have been marketed in the past. This has pushed most Oʻahu investors toward long-term rental and fix and flip strategies rather than vacation rental ownership, since resort-zoned inventory is limited and comes at a significant price premium. If you’re evaluating an Oʻahu property specifically for short-term rental use, confirm its zoning and any nonconforming use certificate status directly with the Department of Planning and Permitting, and see our Oʻahu market guide for financing paths that don’t depend on rental income at all.

Maui Short-Term Rental Rules: Apartment District Phase-Out

Maui County has moved to phase out short-term rental use in properties zoned apartment district, a category that historically included a large share of the condos investors relied on for vacation rental income, particularly in areas like Kīhei. Resort-zoned and hotel-zoned properties are generally treated differently and retain a clearer path to legal nightly rental operation. Because this phase-out has been the subject of ongoing legal and legislative activity, the effective date and scope have shifted over time, and any investor considering a Maui vacation rental purchase should get current, written confirmation of the applicable zoning and any conversion deadline from the County of Maui Planning Department before closing. Our Maui investing guide covers how this shift has changed which submarkets investors are targeting.

Kauaʻi: Visitor Destination Areas

Kauaʻi concentrates legal short-term rental and hotel-type use within Visitor Destination Areas defined in the county’s General Plan, generally covering parts of Princeville, Poʻipū, and the Wailua and Coco Palms area. Properties outside a VDA generally need a nonconforming use certificate to operate legally as a short-term rental, and those certificates are limited in number and tied to specific conditions. This makes VDA status one of the first things to check on any Kauaʻi property being considered for vacation rental use, since the difference between inside and outside the boundary can be a matter of a few blocks.

Hawaiʻi County: Registration Requirements

Hawaiʻi County takes a registration-based approach, generally requiring short-term rental operators to register their unit and demonstrate compliance with zoning, tax, and safety requirements in order to operate legally. Enforcement and registration requirements have tightened over recent years, and unregistered short-term rental operation carries real fine exposure. Given the island’s size and the variation between areas like Kona, Waikoloa, Hilo, and Puna, confirming a specific parcel’s zoning and registration eligibility with the county planning department is essential before underwriting a vacation rental purchase on the Big Island.

How This Changes Exit Strategy

The practical effect of this regulatory tightening is that Hawaiʻi investors increasingly need a plan B, and often a plan A that doesn’t depend on short-term rental income at all. Here’s how that plays out across common strategies:

Fix and flip. Most flips already exit through a sale to an owner-occupant, so short-term rental restrictions have limited direct impact on flip underwriting. Where it does matter is marketing: a property in a former short-term rental building that’s now restricted to long-term use may need repositioning to attract the right buyer, and pricing should reflect the buyer pool that’s actually eligible to use the property, not the buyer pool that existed when nightly rentals were an option.

Long-term rental hold. Many investors previously targeting vacation rentals have shifted to long-term rental as the more durable strategy, since it isn’t exposed to the same regulatory risk. The tradeoff is lower per-unit income, which changes the math on what purchase price and renovation budget still produce a workable deal.

New construction and ADUs. For investors adding units through ADU or new construction, designing explicitly for long-term rental or owner-occupant use from the start avoids betting on short-term rental eligibility that may not materialize or may not survive a future policy change.

A Comparison Table

County	General Approach	Where Short-Term Rentals Are Generally Viable
Oʻahu (Honolulu)	Restricted outside resort zones, plus limited nonconforming use certificates	Waikīkī and other resort-zoned districts
Maui	Phase-out underway in apartment-zoned properties	Resort and hotel-zoned condos and hotels
Kauaʻi	Concentrated in Visitor Destination Areas	Princeville, Poʻipū, and parts of Wailua/Coco Palms
Hawaiʻi County	Registration-based, tightened enforcement	Registered units meeting zoning and safety requirements

This table is a general summary, not a substitute for confirming a specific parcel’s status with the relevant county before you buy.

Staying Current as Rules Change

Short-term rental policy in Hawaiʻi has been an active area of county and state legislative attention, and rules that apply today can shift with relatively little notice as counties respond to housing affordability pressure, court rulings, or new legislation. Investors who purchased under one set of rules have in some cases faced a changed regulatory landscape within just a few years of closing. Building a small cushion into your underwriting for regulatory risk, and checking in periodically with the relevant county planning department rather than assuming the rules you researched at purchase remain fixed indefinitely, is a reasonable practice given how active this area has been.

Financing Implications

None of this changes how hard money underwriting works, since Pac I G Capital’s terms are based on the property, the loan-to-value, and the plan rather than projected rental income. Up to 70% LTV, up to 75% of ARV, and up to 80% of rehab costs remain available at about 1% per month interest-only across all four counties, whether your exit is a sale, a long-term rental hold, or a refinance. What changes is how you should underwrite your own return, since a rental income assumption that depended on nightly rates needs to be replaced with a long-term rental comp or a resale comp instead.

Nonconforming Use Registrations: The Fine Print

One detail that trips up buyers across every county is the assumption that a legal nonconforming short-term rental registration automatically transfers with the sale of the property. In practice, several counties tie these registrations to conditions that can lapse at sale, require a reactivation or transfer application, or impose a use-it-or-lose-it standard if the property sits vacant or unrented for an extended period. A listing advertised as having historical short-term rental income doesn’t guarantee that a new owner can legally continue that use on day one. Before you rely on existing rental history in your offer or your underwriting, request documentation of the specific registration or certificate, confirm directly with the county whether it transfers to a new owner, and understand any conditions that could cause it to lapse.

Working With Your Lender on Exit Strategy

Because short-term rental rules can shift the practical exit options for a property, it’s worth discussing your intended strategy with your lender early rather than after you’ve closed. A lender who understands the current regulatory picture on a given island can help you stress-test whether your plan holds up if short-term rental use isn’t available, whether that means pricing a flip for the buyer pool that actually exists or sizing a rental hold around long-term rather than nightly rates. This is part of why underwriting based on the property and a realistic plan, rather than an optimistic income projection, tends to hold up better over the life of a loan.

Next Step

Before you commit capital to a property with a short-term rental strategy in mind, verify the zoning and registration status with the relevant county planning department, then apply to see what financing terms are available regardless of which exit strategy you choose.
