Hawaii Basement Apartment Renting: Legal Facts & Renter Rights

Thinking of renting a basement apartment in Hawaii? These unique living spaces can offer affordability and privacy, but it's important to understand the laws and requirements that apply to basement rentals in Hawaii. From habitability standards to written leases and your rights as a tenant, here's what every renter should know before signing a basement lease.

What Makes a Basement Apartment Legal in Hawaii?

Not all basement apartments are legally permitted for long-term rental in Hawaii. For a basement unit to be considered a legal rental, it must meet rules set by state and county authorities, especially around health and safety.

• Permitted Unit: The basement must be officially permitted as a dwelling or accessory dwelling unit (ADU) according to local building codes. Illegal or "unpermitted" units may lack critical safety protections and may be subject to fines or removal.
• Minimum Habitability: Hawaii's Residential Landlord-Tenant Code requires all rentals, including basement apartments, to provide safe and sanitary living conditions. Requirements include proper ventilation, safe exits, working smoke detectors, functioning plumbing, and pest-free conditions.
• City & County Rules: Counties such as Honolulu (Oahu), Maui, Kauai, and Hawaii Island each enforce their own building and zoning codes. Always check your county’s Department of Planning or Permitting for specifics.

If you’re unsure about the legal status of a basement rental, ask the landlord for proof of permits and check with your local county permitting office before moving in.

Key Hawaii Renters Rights and Protections

Even in basement apartments, Hawaii renters are protected by the Hawaii Residential Landlord-Tenant Code (HRS Chapter 521)^[1]. Here are some protections that apply:

• Written Lease: While oral leases are legal for month-to-month rentals, it’s safest to have a written agreement. This clarifies rent, length of tenancy, deposits, and rules.
• Security Deposits: The maximum security deposit allowed is one month’s rent.
• Maintenance: Landlords must maintain the rental in a safe, habitable condition. This includes addressing mold, leaks, pests, and providing adequate lighting and ventilation.
• Entry Rights: Landlords must give at least two days’ notice before entering for repairs or inspections (except in emergency situations).
• Eviction Rules: Tenants are entitled to notice before eviction. The timeframe and reasons must follow state law.

For details, see the official Hawaii Tenant Handbook.^[2]

Required Forms and How to Use Them

When renting a basement apartment, you may encounter several official forms and notices. Here are some that Hawaii tenants should know:

• Notice of Termination of Rental Agreement – Form LT-NOTICE
  When used: If your landlord wants to end your lease (for example, for nonpayment of rent or breaking lease rules), they must deliver a formal written notice.
  How to use: Upon receiving a notice, read carefully and check the reason and termination date. Seek help right away if you have questions. Download sample forms and instructions from the Department of Commerce & Consumer Affairs (DCCA).
• Tenant Complaint Form – DCCA Landlord-Tenant Complaint
  When used: If you believe your landlord is violating your rights (e.g., not making repairs, entering without notice, or renting an illegal unit), file this form.
  How to use: Fill out all details and submit it to the Hawaii Department of Commerce and Consumer Affairs, Office of Consumer Protection. Access the Tenant Complaint Form and learn about the process.

These forms are your way of formally asserting or protecting your rights as a tenant.

Safety, Inspections, and Tips for Basement Renters

Basement rentals in Hawaii come with extra considerations:

• Check for proper ventilation, windows, and emergency exits ("egress")
• Ask about past flooding or water issues; basements are prone to moisture and mold
• Ensure smoke and carbon monoxide detectors are working
• Request a move-in inspection and document any damage

Who Handles Tenant Disputes in Hawaii?

In Hawaii, all residential tenancy disputes—such as complaints about illegal eviction, unsafe conditions, or unreturned deposits—are overseen by the Office of Consumer Protection’s Landlord-Tenant Center within the Hawaii Department of Commerce and Consumer Affairs (DCCA). They offer guidance and enforce the Hawaii Residential Landlord-Tenant Code.
