Yes—but with strict limits. On Kauaʻi, short‑term/vacation rentals are lawful only within the Visitor Destination Areas (VDAs), and Kapaa has an established VDA along its coastal corridor (roughly from Waipouli through the Kapaa town area). Outside the VDA, transient rentals are prohibited except for legally established, pre‑existing operations that hold a nonconforming use (NCU) certificate.

Bottom line: If your Kapaa property is inside the VDA and you meet county and state requirements, you can operate. If it’s outside the VDA, you cannot start a new short‑term rental, and existing operations must be properly documented as NCUs to continue.

Note: The county’s VDA boundaries are zoning‑based and can be parcel‑specific (for example, some resort condo complexes or oceanfront parcels inside broader residential areas). Always verify eligibility with the County Planning Department and check the VDA maps.

How to start a short‑term rental (STR) business in Kapaa

1. Confirm your property’s zoning status

• Confirm the parcel is inside a Kapaa VDA. If outside, a new STR is not permitted unless you have a valid TVR/STR nonconforming use (NCU) certificate from before the cutoff.
• Engage a local real estate professional and/or contact the Planning Department for a written determination using the TMK (tax map key). The Planning site links to the “List of Approved Homestays & Non‑Conforming TVR’s by TMK” (see Source Links).

2. Decide on the operational model

• Homestay (host‑present): Rent up to three guest rooms for fewer than 29 consecutive days; owner must reside on‑site and be available 24/7. Requires a homestay zoning permit and annual recertification.
• Single‑Family Transient Vacation Rental (SFTVR): Entire home rental (no host presence required). Only allowed inside the VDA. No separate county registration beyond demonstrating VDA eligibility and maintaining compliance. If you have an NCU certificate (outside the VDA), you can continue to operate subject to annual renewal.

3. Register for state tax licenses (required before or alongside county submittals)

• Transient Accommodations Tax (TAT) license: Hawaiʻi Department of Taxation. $5 (1–5 units); $15 (6+ units). No renewal required once issued.
• General Excise Tax (GET) license: Hawaiʻi Department of Taxation. $15 fee. No renewal required once issued.
• Maintain copies of the TAT and GET license confirmations for your files and any county applications.

4. Prepare safety and compliance documentation

• Evacuation plan and posted emergency information (use the Planning Department’s Sample TVR Evacuation Plan as a template).
• Fire safety equipment: At least one multi‑purpose A:B:C fire extinguisher mounted near an exit and inspected annually (documented).
• Insurance: While the county does not mandate a specific minimum liability coverage, most lenders/hosting platforms require $1,000,000 general liability coverage.
• Website links: Include any advertising URLs if requested (for homestay recertification).

5. Submit the appropriate county application or renewal

• Homestay: Use the current “Homestay Recertification Application” (annually) if you are the incumbent operator. If you are a new homestay applicant, consult the Planning Department for the correct initial application process and fee schedule.
• TVR/STR NCU: If you operate outside the VDA under a prior nonconforming determination, use the current “TVR‑NCU Renewal Application” (annually). New NCUs are not being issued for STR use.

6. Post and collection protocols

• Mail renewal packets by certified mail, return receipt requested, at least two months before the due date to: Planning Department 4444 Rice Street, Suite A473 Līhuʻe, HI 96766
• The returned “green card” is your proof of mailing. Drop‑offs at the front counter are no longer accepted.
• If incomplete, your packet will be returned by USPS. No grace period: late renewals trigger cease & desist and forfeiture.

7. Ongoing compliance and verification

• Use the county’s “List of Approved Homestays & Non‑Conforming TVR’s by TMK” to verify your property’s status and to ensure your operation appears as current.
• Maintain all required documentation (state licenses, insurance, fire extinguisher inspection logs, evacuation plan).
• Keep your contact information current with the Planning Department.

Specific regulations for short‑term rentals: Kapaa, Kauaʻi County, and Hawaiʻi State

Kapaa‑specific (operationally governed by county code and the VDA system)

• Only the Kapaa coastal corridor and other mapped VDA parcels allow STRs; residential parcels outside the VDA do not.
• Two categories:
  • Homestay: ≤ 29 consecutive days; ≤ three guest rooms; owner present and available; requires homestay zoning permit and annual recertification.
  • SFTVR (whole‑home): ≤ 180 consecutive days; no host required; only permitted within VDA.

Kauaʻi County rules that apply to Kapaa

• Permitted areas: STRs allowed within mapped VDAs (e.g., the Kapaa coastal corridor).
• Prohibited areas: Outside the VDA, STRs are not permitted, except for lawfully established NCUs.
• NCU operations:
  • Must have a valid, documented nonconforming use determination for STR.
  • Annual renewal required ($750); mail by certified mail at least two months before due date.
  • No grace period for late renewals; failure triggers cease & desist and forfeiture.
  • No new NCUs for STR use have been issued since 2008.
• Application handling: The county returns incomplete submittals; drop‑offs are no longer accepted.
• Complaints/enforcement: Report suspected unpermitted STRs to Planning for investigation.

Hawaiʻi State statutes and policy context

• State definition (HRS §237D): “Transient accommodations” are lodgings provided for fewer than 180 consecutive days per letting.
• State taxes:
  • Transient Accommodations Tax (TAT): 10.25% of gross rental income (state portion), plus any county TAT.
  • General Excise Tax (GET): 4% statewide, plus any applicable county surcharge.
• State legislative development (SB 2919, signed May 3, 2024):
  • Explicitly authorizes counties to regulate the time, place, manner, and duration of transient accommodation uses by ordinance.
  • Enables amortization or phase‑out of transient uses in residential or agricultural zones.
  • Counties have already used VDA frameworks for years (Kauaʻi has done so since 2009).

Selling or buying an existing TVR property (county best practices)

• Seller should provide the buyer with:
  1. The complete file documenting that the STR use was properly determined to be nonconforming (if applicable),
  2. The most recent completed renewal application and all attachments, and
  3. The Planning Department’s latest renewal letter.
• If the seller’s realtor does not provide these, the buyer or buyer’s realtor should request them. The Planning FAQ explicitly cautions “Buyer beware!”

Tax reminders for hosts

• TAT and GET registration are statewide licensing requirements; TAT does not require renewal once issued. GET does not require renewal once issued.
• County surcharges and TAT may apply in addition to the state tax; consult the Hawaiʻi Department of Taxation and current county notices for current rates.
