A lot of buyers looking at Keauhou condos run the short-term rental numbers before they run anything else. The Kahaluu-Keauhou area draws steady visitor demand, the bay and beach access are genuine draws, and the price points for some buildings make the income math look attractive at first glance. The problem is that the first glance often misses the most important variable: whether the specific unit is actually eligible to operate as a short-term rental at all.
After 35 years of helping people buy and sell in this market, I can tell you the buyers who are most surprised mid-transaction are the ones who assumed the rental status rather than confirming it. The rules here come from three separate sources, and all three can say no independently.
Key Takeaways
- Short-term rental eligibility in Keauhou is determined by three independent layers: your AOAO's governing documents, Hawaii County's NUC permit requirements, and state tax registration. All three must align before you can legally operate.
- Hawaii County stopped issuing new Non-Conforming Use Certificates for short-term rentals in most residential zones. If you want to operate a legal short-term rental in a Keauhou residential condo, you need a unit that already has a valid, transferable NUC.
- Even if county rules allow short-term rentals, your AOAO can prohibit them in the CC&Rs or bylaws. This is not uncommon in Keauhou buildings and is not negotiable.
- State taxes apply to all vacation rentals in Hawaii. Transient Accommodations Tax and General Excise Tax must be registered and remitted regardless of what platform you use to list the property.
- Get a written confirmation of rental eligibility from the AOAO for any specific unit before you write an offer. Do not rely on what a previous owner did or what a listing agent says informally.
The Three Layers You Have to Navigate
Understanding where each layer of authority comes from saves significant confusion and potential legal exposure.
The AOAO (the Association of Apartment Owners) governs condominium properties in Hawaii the way HOAs govern planned communities elsewhere. The AOAO's authority comes from the governing documents: the declaration, CC&Rs, bylaws, and house rules. These documents establish whether and how short-term rentals are permitted in the building. Some Keauhou buildings explicitly prohibit short-term rentals. Others allow them with conditions. A few have no restrictions. The documents are the definitive source, not the current rental activity in the building.
Hawaii County controls zoning, permitting, and enforcement. In most residential zones, short-term vacation rentals require a Non-Conforming Use Certificate. Hawaii County stopped issuing new NUCs for most residential zones under the current ordinance. That means the only path to legal short-term rental operation in a residential Keauhou condo is buying a unit that already has a valid NUC and confirming it transfers with the sale. Some listings reference existing NUCs. Some of those NUCs are valid and transferable. Some are not. Confirm directly with the county and get written confirmation before you rely on it.
The State of Hawaii requires all vacation rental operators to register for and remit two taxes: the Transient Accommodations Tax on short-term stays and the General Excise Tax on gross rental receipts. Rates and filing requirements change. Some platforms collect and remit certain taxes in certain jurisdictions, but you remain responsible for compliance unless state guidance specifically confirms full platform remittance for your situation. Register before you accept your first booking, not after.

AOAO Due Diligence: What to Request and Review
Before you write an offer on any Keauhou condo you plan to rent short-term, request and review the full set of governing documents. This means the declaration of the Condominium Property Regime and CC&Rs, the bylaws, the current house rules and any Rental Rules booklet, board meeting minutes from the past 12 to 24 months, the current budget and reserve study, financial statements, and any special assessment notices.
What you are looking for in those documents: any explicit prohibition on short-term rentals, minimum stay requirements if rentals are allowed, caps on the number of units permitted to operate as short-term rentals, waitlist requirements, required local contact or licensed property manager provisions, and any pending board votes to modify rental rules. Pending rule changes matter as much as current rules. A building that allows short-term rentals today may be voting to restrict them next quarter.
Ask for a written statement from the AOAO confirming the specific unit's current rental status and whether any rule changes affecting that status are pending. Verbal assurances from a listing agent or a previous owner do not constitute confirmation of legal eligibility. Get it in writing from the association itself.
The financial health of the AOAO is a separate but equally important review. Low reserve funds, frequent special assessments, or deferred maintenance that is not in the budget all affect your carrying costs and your ability to maintain rental income without unexpected expenses.

Insurance: Do Not Assume Your Standard Policy Covers Rentals
Standard condo or homeowner insurance policies typically exclude short-term rental activity. If you operate a rental without appropriate coverage and a guest is injured or causes damage, you are exposed. Ask your insurer specifically about a vacation rental or commercial use endorsement that meets AOAO certificate of insurance requirements.
Most AOAOs require owners to carry a minimum liability coverage limit and to name the AOAO as an additional insured. Confirm the specific requirements for your building, get a certificate of insurance that meets them, and maintain it continuously while you are operating. Consider an umbrella liability policy as well, particularly if you are managing the rental yourself without a licensed property management company.
Modeling Returns: What the Numbers Actually Look Like
The Kahaluu-Keauhou area has strong visitor demand driven by Kahalu'u Beach Park, Keauhou Bay, the manta ray tours, and proximity to the broader Kona market. Demand is seasonal but genuine. Before you build a pro forma, understand the inputs that actually drive it.
For nightly rate and occupancy data, paid platforms like AirDNA provide structured ADR and occupancy statistics for Keauhou-area vacation rentals. Build your model using seasonal assumptions rather than annual averages. Kona has peak periods and slower periods, and a model built on annual averages will overestimate income during slow months and underestimate it during peak ones.
The expense line items to budget honestly: full-service property management in Hawaii typically runs 20 to 35 percent of gross revenue; cleaning, linen service, supplies, and utilities; platform fees and credit card processing; TAT and GET remittance; HOA dues and any AOAO rental-specific fees; homeowners and liability insurance; property taxes; mortgage payments if applicable; and a reserve for furnishing replacement, repairs, and vacancy. Build a conservative model. Then build a more conservative one. The buyers who are surprised by vacation rental performance are almost always the ones who modeled peak occupancy at peak rates with minimal expenses.
Financing and Resale Considerations
Lenders treat condo vacation rentals differently from standard residential condos. If a significant portion of units in a building operate as vacation rentals, the project may be classified as a condotel, which has different and often more restrictive financing options. Confirm your lender's requirements for the specific building before you proceed. Some buildings that appear to allow rentals freely are difficult to finance with conventional loans as a result.
On resale, a building that prohibits short-term rentals attracts a different buyer pool than one that allows them. AOAO policies, building financial health, and current local regulations all affect resale value. A building that restricts or bans short-term rentals may still be an excellent purchase for the right buyer, but that buyer needs to be a resident or long-term rental operator, not someone whose plan depends on vacation rental income.
Frequently Asked Questions
Can I operate a short-term rental in a Keauhou condo?
Only if the unit has a valid, transferable Non-Conforming Use Certificate from Hawaii County and the AOAO's governing documents permit short-term rentals. Both conditions must be met. Hawaii County stopped issuing new NUCs for most residential zones, so you cannot simply apply for one after you buy. The NUC must already exist and must transfer with the sale. Confirm both the NUC status and the AOAO rules in writing before you write an offer.
What taxes apply to vacation rental income in Hawaii?
Two state taxes apply to virtually all vacation rental operations in Hawaii: the Transient Accommodations Tax on short-term rental income and the General Excise Tax on gross receipts. Both must be registered with the Hawaii Department of Taxation and remitted regularly. Some platforms collect and remit certain taxes in certain jurisdictions, but the obligation for compliance remains with the owner. Register before you accept your first booking.
What AOAO documents should I review before buying a Keauhou vacation rental condo?
The declaration and CC&Rs, bylaws, current house rules and any Rental Rules booklet, board meeting minutes for the past 12 to 24 months, the current budget and reserve study, financial statements, special assessment notices, and insurance requirements. Also request a written statement from the AOAO confirming the specific unit's rental eligibility and whether any rule changes affecting that status are pending. Verbal assurances are not sufficient.
What property management costs should I budget for a Keauhou vacation rental?
Full-service property management in Hawaii typically runs 20 to 35 percent of gross rental revenue. In addition, budget for cleaning and linen service, supplies and utilities, platform fees and credit card processing, state tax remittance, HOA dues and AOAO rental fees, insurance, property taxes, and a reserve for repairs and furnishing replacement. Build a conservative pro forma that accounts for seasonal vacancy, not just average annual occupancy.
How does short-term rental status affect financing and resale?
Lenders may classify buildings with high rental activity as condotels, which have more restrictive financing options than standard residential condos. On resale, AOAO rental policies affect your buyer pool. A building that prohibits short-term rentals attracts residents and long-term rental investors rather than vacation rental buyers. Understand the financing and resale implications of the specific building's rental policy before you commit.
Are short-term rental rules different for condos versus single-family homes in Kona?
The county NUC requirement applies in most residential zones regardless of property type. For condos, the AOAO layer adds a second set of rules that single-family homeowners do not face. A single-family home in a residential zone with a valid NUC can operate as a short-term rental without AOAO approval. A condo must comply with both county rules and AOAO restrictions. In practice, many Keauhou condo buildings have stricter rental rules than the county itself imposes.
