Lease Template for Renting Out a Room in Your Home: Tax, FHA, Sample Language (2026)

The legal status: tenant or lodger?

The first question for a homeowner renting a room is the legal classification of the room renter. Most state landlord-tenant statutes apply to all residential tenancies regardless of building size or owner occupancy, treating the room renter as a tenant with all the procedural protections of that status. A few states have specific owner-occupant rules that create a different classification (often "lodger" or "licensee") with simpler termination procedures.

California Civil Code section 1946.5 provides a notable example. The section applies to room rentals in owner-occupied dwellings where the owner occupies the dwelling as their principal residence and rents one room (no carve-out for multiple rooms in some readings). Under section 1946.5, the owner may terminate the room rental on a notice equal to the rent period (typically 7 days for week-to-week, 30 days for month-to-month), without going through formal unlawful detainer eviction. The simplified procedure recognises that an owner sharing their primary residence with a lodger has stronger privacy interests than a traditional landlord at arm's length.

Most other states do not have a similar simplified procedure. New York treats room rentals as standard tenancies subject to RPL and the full eviction procedure (with HSTPA notice periods applying). Texas treats room rentals as standard tenancies under Property Code Chapter 92. Florida treats room rentals as either standard residential tenancies under Chapter 83 or as boarding situations depending on the specific arrangement. The take-away is to verify the specific state's treatment before relying on simplified procedures.

Even where the simplified procedure applies, self-help eviction is unlawful in every state. The homeowner cannot change locks, remove the lodger's belongings, or physically eject the lodger. The simplified procedure provides a faster legal route, not a self-help route. The homeowner who tries self-help in any state, including California, faces civil liability for damages and potentially criminal liability for tenant-protection statute violations.

The Fair Housing Act and the Mrs. Murphy exception

The Fair Housing Act (42 USC sections 3601 to 3619) prohibits discrimination based on race, colour, national origin, religion, sex (including sexual orientation and gender identity following Bostock-derived HUD guidance), disability, and familial status. The Act applies to nearly all rental housing but contains narrow exceptions under section 3603(b).

The Mrs. Murphy exception, codified at 42 USC section 3603(b)(2), exempts dwellings with no more than four rental units in which the owner occupies one of the units. The exception applies to the FHA's general prohibitions but does not waive the FHA's prohibition on discriminatory advertising under section 3604(c). The practical effect is that a homeowner renting rooms in an owner-occupied home with no more than three other rental units can select roommates with broad latitude, but cannot publish discriminatory advertisements.

Asking selection questions privately, in conversation with prospective lodgers, is generally permitted under the Mrs. Murphy exception. Asking publicly through advertising language ("women only," "Christians preferred," "no children") remains unlawful even under the exception. The advertising restriction is strict; even advertisements that disclaim discrimination ("preference for graduate students" can be challenged if it tends to exclude protected classes) face scrutiny.

State and local fair-housing laws often extend beyond the FHA. California's Fair Employment and Housing Act prohibits sexual-orientation discrimination throughout the state, including in roommate selection in some circumstances. New York City's Human Rights Law extends similar protections to roommate selection in covered buildings. Several states and localities cover source-of-income discrimination (refusal to accept Section 8 vouchers or similar income) that the FHA does not reach. Always check state and local law alongside the federal framework.

The Ninth Circuit's decision in Fair Housing Council of San Fernando Valley v. Roommates.com (2008) held that an online roommate-matching service was not exempt under the Mrs. Murphy exception when the service published discriminatory advertising. The case established that online platforms enabling such selection face FHA scrutiny. Modern roommate-matching services typically avoid asking users for protected-class information to limit their own FHA exposure.

Federal tax treatment under IRC 280A and the Augusta Rule

Rental income from a room in the homeowner's primary residence is reportable on IRS Schedule E. The homeowner reports the gross rental income and may deduct a proportional share of mortgage interest, property taxes, utilities, depreciation, insurance, and maintenance expenses. The proportional share is calculated based on the rented portion of the home, typically by square footage (rented bedroom plus a share of common spaces, divided by total home square footage).

IRC section 280A imposes personal-use limitations that restrict the deductibility of expenses. The rules are complex, with different treatment depending on whether the room is rented for more or less than 14 days during the year and the relative amounts of rental and personal use. For most year-round room rentals, the homeowner can deduct expenses proportional to the rental use, subject to a limitation that total deductions cannot exceed gross rental income (preventing loss harvesting from the personal-use portion).

The Augusta Rule under section 280A(g) provides a notable exception. If the home is rented for fewer than 15 days during the year and the homeowner uses it as a residence for more than 14 days, the rental income is excluded from gross income entirely. The Augusta Rule originated with Augusta, Georgia homeowners renting their homes during the Masters golf tournament and remains a powerful tax exception for short-term, high-value rentals. The Augusta Rule does not apply to traditional year-round room rentals, but homeowners with high-demand homes near major events (graduation weekends, sports championships, festivals) can benefit.

For the typical year-round room rental, the tax outcome depends on specifics. A homeowner renting one bedroom in a 4-bedroom home (rented at 1/4 of total square footage) deducts 25 percent of mortgage interest, property taxes, utilities, depreciation, insurance, and maintenance on Schedule E. Net rental income (after deductions) is taxable at standard income tax rates. The deductions can substantially reduce or eliminate the taxable rental income, particularly in early years when depreciation deductions are largest.

State income tax follows the federal framework with state-specific quirks. California, New York, and several other states have additional state-level rental rules. Property tax treatment may also change when a portion of the home becomes rental: some jurisdictions reassess property tax based on a partial commercial use, though most do not for single-family-home room rentals.

Insurance: homeowner's policy and renter's insurance

The homeowner's insurance policy typically does not fully cover the room-rental scenario. Most standard homeowner's policies are designed for single-family owner-occupied homes without rental income. Adding a paying lodger may trigger coverage exclusions or require an endorsement.

The most common policy adjustment is an "occasional rental" endorsement, which covers limited rental of rooms in an otherwise owner-occupied home. The endorsement typically permits a defined number of nights or paid guests per year, with limited liability coverage. Year-round room rentals may exceed the endorsement and require a different policy structure (a landlord's policy with owner-occupied carve-outs, or a different insurance product entirely).

The homeowner should also require renter's insurance from the lodger. Renter's insurance covers the lodger's personal property and provides liability coverage for incidents the lodger causes. Typical renter's insurance policies cost 15 to 30 dollars per month and provide 100,000 to 300,000 dollars in liability coverage. The homeowner can be named as additional insured on the renter's policy, extending the liability protection to incidents involving the homeowner.

The lease should require the lodger to maintain renter's insurance throughout the tenancy and to provide proof annually. Some states have considered legislation restricting landlord-imposed renter's insurance requirements (concerned about cost burden on low-income tenants), but as of 2026 such requirements are generally permissible. Always verify the specific state rule before imposing the requirement.

Common mistakes by homeowner-landlords

The most common mistake is treating the room rental as an informal arrangement without a written agreement. A handshake roommate situation works fine until the first dispute (unpaid rent, damage to common spaces, an unwelcome new partner moving in), at which point both parties have no documented expectations and the default state law applies. A short written agreement preventing the dispute is far cheaper than a verbal arrangement leading to one.

The second most common mistake is assuming the homeowner can self-evict because it is the homeowner's own home. Self-help eviction is unlawful in every state, including states with simplified owner-occupant termination procedures. The simplified procedures provide a faster legal route, not a self-help route. A homeowner who changes locks or removes a lodger's belongings faces civil and potentially criminal liability regardless of the underlying merit of the termination decision.

The third common mistake is failing to report rental income to the IRS. The income is reportable on Schedule E regardless of how informal the arrangement. Failure to report can be flagged by the lodger's payment records (Venmo, bank transfers) or by the lodger's own claim of rent as a deduction in some circumstances. The IRS has increased enforcement on informal rental income in recent years. Best practice is to track rental income carefully and file Schedule E.

The fourth common mistake is failing to verify insurance coverage. Standard homeowner's policies often exclude or limit coverage for paying lodgers. A homeowner who has not added an occasional-rental endorsement or switched to a compatible policy may find that an incident involving the lodger leaves the homeowner uninsured. Contact your insurance agent before bringing the first lodger into the home, not after.
