Lodger Rental Agreement Template for the United States

A lodger rental agreement is a specialized legal contract that governs the relationship between a homeowner who lives in their property (the resident landlord) and someone who rents a room within that same residence (the lodger). This arrangement falls under specific lodger provisions in United States housing law, giving the homeowner more control over the shared living space while generating rental income from a spare room.

What is a lodger agreement in California?

In California, a lodger is a person who rents a room in a home where the owner also lives and keeps access to the whole property. When there is only one lodger in an owner-occupied home, California Civil Code Section 1946.5 treats the arrangement differently from an ordinary tenancy. The owner can end it by giving written notice equal to the length of the rental period, so someone paying monthly generally receives a 30-day notice. Once that period ends, the resident no longer has the right to remain, and the standard court eviction process usually does not apply. If you rent to two or more people, this single-occupant rule does not apply and normal tenant protections generally do. A written agreement records which rule applies and the notice both sides have agreed to follow.

When do you need this document?

You need a lodger agreement whenever you want to rent out a room in your primary residence while continuing to live there. This commonly arises when homeowners in expensive metropolitan areas like San Francisco, Los Angeles, New York, or Boston want to offset mortgage costs by sharing their space. University towns frequently see owners renting to students, while empty nesters might let a spare room to supplement retirement income. The agreement is also useful if you are providing temporary housing to visiting professionals, international students, or individuals seeking short-term accommodation. You might even be taking in a friend or extended family member on a formal paying basis. Without a written agreement, you risk disputes over shared facilities, unclear house rules, payment timing, and confusion over lodger status versus full tenant rights.

What should a lodger agreement include?

A complete agreement covers the following:

• The names and contact details of the resident landlord and the lodger, and the address of the home.
• The room being rented and which shared facilities the occupant may use, such as the kitchen, bathroom, and living areas.
• The rent amount, the payment method, the due date, and how much notice applies to any change in the monthly charge.
• The security deposit, how it is held, and when it is returned after the arrangement ends.
• House rules covering guests, noise levels, cleanliness, smoking, pets, and use of common areas.
• The notice period each side must give to end the arrangement, including the California single-lodger notice where it applies.
• The landlord's right to access all areas of the property, so the occupant does not gain exclusive possession beyond their room.

What is the notice period for a lodger?

The notice period is the single term that homeowners and lodgers disagree over most, so state it plainly. In a California owner-occupied home with one lodger, the notice equals the rental period: a monthly arrangement means a 30-day written notice, a weekly one means seven days. Worked example. A room costs $1,200 paid on the first of each month. To end the arrangement, the homeowner gives written notice on March 3; the notice period runs a full month, so the right to stay ends on April 3. Record the agreed period in the document itself so neither side has to work it out later.

Key legal considerations

Your agreement should make clear that you keep the right to access all areas of the property and that the occupancy does not create exclusive possession of any space beyond the designated room. Set out shared facilities in detail to prevent disputes. Address house rules across guests, noise, cleanliness, and common areas. Set clear termination and notice procedures, since lodgers typically have fewer protections than traditional tenants. Include security deposit terms that follow your state's rules, and make sure the agreement does not accidentally create a full landlord-tenant relationship that would add legal obligations. Consider liability and insurance, as your homeowner's policy may need adjusting to cover room-letting risks.

How do you end a lodger agreement?

To end the arrangement, give written notice for the period stated in the agreement and required by your state. In a California owner-occupied home with a single lodger, notice equal to the rental period (commonly 30 days for a monthly arrangement) ends the right to stay, and no court eviction is usually needed. In other states, or where more than one person lives in the home as a paying occupant, you generally follow the standard notice and eviction steps for tenants. Keeping a signed agreement and a dated copy of any notice helps both sides follow the same process and reduces disputes.

Legal requirements in the United States

Your agreement must follow the federal Fair Housing Act, which prohibits discrimination based on race, color, national origin, religion, sex, familial status, or disability. Under the Americans with Disabilities Act, you must provide reasonable accommodations for disabled occupants unless doing so creates undue hardship, and give any accessibility request a fair review. You must also handle the occupant's personal information consistent with applicable privacy rules, so collect only what the arrangement needs and keep it secure. If you advertise the room on social media or sites like Facebook, apply the same fair-housing standards to any listing, comment, or message exchange, and follow each platform's privacy policy on the data you hold about applicants. State landlord-tenant rules vary, and California has specific lodger provisions under Civil Code Section 1946.5 that differ from standard tenant protections. Many states expect the room to meet local housing codes on minimum size, safety, and occupancy limits. Security deposit rules vary by state, with some requiring separate accounts and specific return timeframes. Some jurisdictions require disclosures about lead paint, mold, or other hazards. Check local zoning rules that may limit the number of unrelated occupants in a residential property. If you run the arrangement as a side income, keep a record of rental income for tax reporting.
