Landlord-Tenant Law: Complete Guide for All 50 States (2026)

Landlord-tenant law in the United States is a patchwork of federal, state, and local regulations that govern every aspect of the rental relationship. Understanding these laws is essential for both landlords seeking to protect their property and income, and tenants seeking to protect their rights and their home.

Federal Law: The Fair Housing Act

The Fair Housing Act (42 U.S.C. § 3601 et seq.) is the foundational federal law governing rental housing. It prohibits discrimination based on race, color, national origin, religion, sex, familial status, and disability. Familial status protection means landlords cannot refuse to rent to families with children under 18 — though communities that qualify as "55 and older" housing may have exemptions.

The Fair Housing Act applies to virtually all residential landlords with limited exceptions for very small owner-occupied properties (the "Mrs. Murphy" exemption for 4 or fewer units where the owner lives in one of them).

Security Deposit Laws by State

Security deposit laws are among the most state-specific aspects of landlord-tenant law. Here are the key states:

**California**: Maximum deposit of 2 months rent (unfurnished) or 3 months rent (furnished). Must be returned within 21 days of move-out with an itemized statement of deductions. Interest is not required statewide but some cities require it.

**New York**: Security deposit capped at 1 month's rent (for most residential tenants under the HSTPA). Must be kept in a separate account and returned within 14 days of move-out with an itemized statement.

**Texas**: No statutory maximum on security deposits. Must be returned within 30 days of surrender of the premises. Wrongful withholding allows the tenant to recover 3x the amount wrongfully withheld plus attorney's fees.

**Florida**: No statutory maximum. Must be returned within 15 days (if no deductions) or 30 days (with itemized deductions sent by certified mail).

Eviction Procedures: Notice Requirements

The eviction process begins with a written notice and differs significantly by state and type of violation:

**Non-Payment of Rent**: Most states require 3–5 days to pay or quit. New York now requires 14 days. Massachusetts requires 14 days. Oregon requires 10 days.

**Lease Violations**: Most states require 10–30 days to cure or quit for non-payment violations like unauthorized pets or damage.

**Month-to-Month Termination**: Most states require 30 days notice; California and Oregon require 60–90 days for long-term tenants.

Habitability Standards

Every state imposes an implied warranty of habitability — the landlord's obligation to maintain the rental unit in livable condition. While standards vary, virtually every state requires:

- Functional heating during cold weather - Hot and cold running water - Working electrical systems - Structurally sound floors, walls, and roof - Functional locks and security measures - Freedom from pest infestation

Landlords who fail to maintain habitability face rent withholding, rent escrow, repair-and-deduct remedies, and lease termination rights — depending on state law.
