To write a contract for renting a room, put in writing the full names of landlord and tenant, the address and specific room being rented, the lease term, the rent and late-fee terms, the security deposit rules, utilities, house rules for shared spaces, maintenance responsibilities, entry notice, subletting and termination terms, any required legal disclosures, and the signatures of both parties. Even a one-page document, signed and dated, creates enforceable rights on both sides.
Gather the Details Before You Draft
Settle the facts first so you aren’t negotiating while writing. You need full legal names and current contact information for both parties, the complete property address, and a precise description of the room. “The southeast bedroom on the second floor” works. “A room in the house” does not.
Lock in the financial terms too: monthly rent, security deposit amount, start date, and end date if the lease is for a fixed term. A contract with “TBD” in the rent field is a contract waiting to cause problems.
Identify the Parties and the Room
Open the agreement by naming the landlord and tenant by their full legal names and stating the complete property address, including unit or floor number if applicable. Describe the rented room clearly enough that a stranger could walk into the house and find it. If a dispute later turns on which room was rented, the contract has to answer that question on its own.
State the Lease Term
Write exact start and end dates for a fixed-term lease. For a month-to-month arrangement, say the agreement automatically renews each month until either party gives written notice to end it. The required notice period for ending a month-to-month tenancy varies by state, typically ranging from 30 to 90 days, so check your local rule and write the correct number into the contract.
A fixed-term lease gives both sides more stability. Month-to-month gives flexibility with less predictability. Pick one and be explicit about it.
Set the Rent and Late Fee
The rent clause needs four things: the exact dollar amount due each month, the day it is due, the payment methods you accept, and what happens when rent is late. Most landlords set rent due on the first, but any date you both agree to is fine.
For late fees, state the grace period and the fee amount. Caps vary by jurisdiction: some states set a flat dollar limit, some cap fees as a percentage of rent, and some simply require the fee to be “reasonable.” Whatever you choose, write it in. A vague late-fee policy is almost as bad as no policy at all.
Security Deposit and Move-In Condition
State the deposit amount and spell out what the landlord can deduct from it. Typical deductions cover unpaid rent and damage beyond normal wear and tear. Be specific about the distinction. A scuffed baseboard from moving furniture is wear. A hole punched in the wall is damage.
Include a timeline for returning the deposit after move-out. State deadlines generally range from 14 to 60 days, and most states also require the landlord to provide an itemized list of any deductions. Put both the deadline and the itemization requirement into the contract.
Pair the deposit clause with a move-in inspection. On or before the move-in date, walk through the room together and note the condition of walls, floors, windows, fixtures, and appliances. The U.S. Department of Housing and Urban Development recommends a joint move-in/move-out inspection specifically for “determining damages caused by the tenant during tenancy and allowable deductions from the tenant’s security deposit.”1U.S. Department of Housing and Urban Development. Move-In/Move-Out Inspection Form Take dated photos of existing damage, and attach the completed checklist to each signed copy of the agreement. Do the same walkthrough at move-out, and compare.
Spell Out Utilities
Utilities are one of the most common sources of friction in room rentals. You have options: include utilities in the monthly rent as a flat rate, split costs evenly among occupants, divide them by the rented room’s share of total square footage, or have the tenant pay certain accounts directly. Whichever you choose, list which utilities are covered and which belong to the tenant: electricity, gas, water, internet, trash. If utilities are included in rent, consider a clause addressing what happens if usage spikes sharply.
Write House Rules for Shared Spaces
A room rental involves shared kitchens, bathrooms, and living areas, so the agreement needs rules a standard apartment lease would not. Be specific rather than relying on general language about being “respectful.” Cover at least these areas:
- Guests: whether overnight guests are allowed, how many nights per week or month, and whether advance notice to the landlord is required.
- Pets: whether pets are allowed, any restrictions on type or size, and any additional pet deposit.
- Quiet hours: specific times, such as 10 p.m. to 7 a.m.
- Smoking: prohibited entirely, or restricted to designated outdoor areas.
- Cleaning: who cleans shared spaces and how often, whether through a rotating schedule or divided duties.
- Shared amenities: rules for laundry, parking spots, and storage.
Enforceability turns on these rules being in the signed contract. A verbal agreement about kitchen cleanup will not hold up when things go wrong.
Maintenance and Right of Entry
In most states, landlords carry an implied warranty of habitability, meaning they must keep the property safe and livable regardless of what the lease says. The contract should assign major repairs (structural issues, plumbing, heating, electrical) to the landlord and limit the tenant’s obligations to keeping the room clean, avoiding damage, and promptly reporting problems. The tenant pays for damage they cause, not for things that break through normal use.
Right of entry matters more in a shared home than in a standard apartment because the landlord is physically present. Require written or verbal advance notice before the landlord enters the room for non-emergency purposes like inspections or repairs. States that specify a timeframe typically require 24 to 48 hours; others use a “reasonable notice” standard. Emergencies such as fires or water leaks are the exception, and the contract should say so.
Subletting and Termination
Include a clause prohibiting the tenant from subletting or assigning the lease without the landlord’s prior written consent, with any attempt to do so without approval being void. In a room rental, the landlord chose this particular tenant to share living space with, and the clause preserves that choice.
The termination clause establishes how either party ends the tenancy. For month-to-month, state the number of days of written notice required, using your state’s figure. For a fixed-term lease, say what happens when the term expires: does it convert to month-to-month, or does the tenant need to notify the landlord of intent to renew by a certain date? Also consider grounds for early termination, such as material breach, and any penalty for breaking a fixed-term lease early.
Property Left Behind After Move-Out
When a tenant moves out and leaves belongings behind, in most states the landlord cannot simply throw everything away. Rules vary widely: some states require the landlord to store items for a set period and send written notice before disposing of them; others allow disposal almost immediately. Include a clause stating how many days the tenant has to claim property left in the room and that the landlord may dispose of or sell unclaimed items after that period. The contract will not override a more protective state law, but it puts both parties on notice.
Include Required Legal Disclosures
For any housing built before 1978, federal law requires the landlord to disclose known lead-based paint hazards, provide all available records and reports about lead in the property, and give the tenant a copy of the EPA pamphlet “Protect Your Family From Lead in Your Home” before the lease is signed.2U.S. Environmental Protection Agency. Real Estate Disclosures About Potential Lead Hazards The lease itself must include a Lead Warning Statement, either attached or inserted into the text.3Office of the Law Revision Counsel. 42 USC 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property
A landlord who knowingly violates this disclosure requirement can be held liable for three times the tenant’s actual damages, plus court costs and attorney fees.3Office of the Law Revision Counsel. 42 USC 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property Many states and localities also require additional disclosures (mold, flood zones, sex offender registries, bed bug history, and others). Check your local requirements and include every mandated disclosure.
Watch Fair Housing Rules When Advertising
Room rentals in owner-occupied homes sit in an unusual place under federal fair housing law. The Fair Housing Act contains an exemption for owner-occupied dwellings with no more than four independent units, which can allow the owner to apply personal preferences when choosing a tenant. The advertising prohibition has no such exemption: federal law flatly prohibits any ad indicating a preference or discrimination based on race, color, religion, sex, disability, familial status, or national origin.4Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices
Describe the room and the living situation without describing the type of person you want. “Sunny room with shared bathroom, $800/month” is fine. Language about preferred demographics is not. One recognized exception in shared living: you may state a same-gender preference when residents share a bathroom or other intimate spaces. Many states and cities have stricter fair housing rules than federal law, so check local requirements before posting.
Know the Tax Side
Rent you collect is taxable income. Room rental income from your primary residence generally goes on Schedule E of your tax return.5Internal Revenue Service. Topic No. 414, Rental Income and Expenses You can deduct a proportional share of expenses such as mortgage interest, property taxes, insurance, utilities, and repairs, based on the percentage of your home’s square footage the rented room represents. A 200-square-foot room in a 1,600-square-foot home means you can deduct 12.5% of shared expenses against the rental income.
One exception: if you rent the room for fewer than 15 days during the tax year, you do not have to report the rental income at all. You cannot deduct rental expenses for those days either, but you can still deduct mortgage interest and property taxes on Schedule A as usual.6Internal Revenue Service. Publication 527, Residential Rental Property For anything beyond 14 days, keep detailed income and expense records from day one.
Sign, Attach, and Keep
Both parties should read the entire contract before signing. This is the last chance to catch errors, clarify ambiguous language, and make sure no blank is empty. Both the landlord and tenant then sign and date, and each party keeps a complete signed copy. Attach the move-in condition checklist, the lead paint disclosure if applicable, and any other required addenda so every copy is a complete package. Store yours somewhere you can actually find it.
