That empty bedroom could cover part of your mortgage, but handing over a key without a plan can get messy fast. Maybe your new renter leaves dishes in the sink, has guests over every weekend, or pays late and says you never discussed a due date. When the arrangement lives only in conversation, everyone remembers it differently. A written agreement settles these questions before they turn into arguments. This guide walks through each section to include, from rent and shared spaces to house rules and move-out notice, so you can rent out a room with confidence.
Step 1: Name the Parties and Describe the Room
Start with the full legal names of the landlord or principal tenant and the person renting the room. Then describe the specific room, along with anything that comes with it, such as a closet, storage space, or parking spot. A room rental agreement covers one private room in a shared home, not an entire unit, so this part sets the boundaries clearly.
Step 2: List the Shared Spaces
Spell out which common areas the renter may use, such as the kitchen, bathroom, living room, or laundry room. Note any off-limits areas too, like a locked closet or home office. Specific wording here prevents the “I didn’t know I couldn’t use that” conversation later.
Step 3: Set the Rent, Due Date, and Payment Method
State the monthly amount, the day it is due, and how it should be paid. If you charge late fees, include them, and check your state’s limits first. Keeping a record of each payment helps both sides, and a signed rent receipt works well for that.
Step 4: Cover the Security Deposit
Write down the deposit amount and the conditions for returning it. Some states cap deposits or require them to be held in a separate account, so confirm your local rules before finalizing this section. A walkthrough of the room before move-in, with photos, helps document its condition.
Step 5: Divide Utilities and Shared Costs
Say which utilities are included in the rent and how the rest will be split, such as internet, electricity, or trash service. A simple fixed amount or percentage keeps things fair and avoids monthly debates.
Step 6: Add House Rules
Cover guests, quiet hours, smoking, pets, and cleaning duties for shared areas. Clear expectations reduce daily friction, especially when two lifestyles share one kitchen.
Step 7: Set the Term and Termination Notice
Decide whether the arrangement runs month-to-month or for a fixed period, and state how much written notice each side must give to end it. Thirty days is common for month-to-month tenancies, though required notice periods vary by state.
Step 8: Review Signing Requirements and Share Copies
Both parties should sign, and a guarantor should sign as well if one is involved. Notarization is generally not required, but check your state’s rules. If the property was built before 1978, federal law generally requires a lead-based paint disclosure. Each person keeps a signed copy. Landlords who want a ready-made format can use a room rental agreement built for their state.
Quick Checklist: Names, room description, shared spaces, rent and due date, deposit, utilities, house rules, term, notice period, and signatures.
Room Rental Agreement vs. Roommate Agreement vs. Sublease
These three documents are often confused. A room rental agreement is between the landlord (or principal tenant) and the new occupant. A roommate agreement is between people already sharing a lease and mostly covers chores and bills. A sublease applies when a tenant hands off space and usually needs the landlord’s written approval.
Conclusion
A spare room can bring in steady income, and a clear written agreement keeps that income from costing you peace of mind. Name the parties, define the room and shared spaces, set rent and deposit terms, divide utilities, add house rules, and spell out how to end the arrangement. Check your state’s requirements before signing, and keep a copy for everyone involved. When expectations are on paper from day one, living together tends to go much more smoothly.
