Unlike a traditional lease where a group of tenants leases an entire building, a room-rental agreement establishes terms for a single individual occupying a specific bedroom while sharing common spaces. A detailed lease helps clarify expectations and reduce disputes.

1. Defining Private vs. Common Areas

Clearly designate which areas are for the tenant's exclusive use (e.g., Bedroom B, private bathroom) and which spaces are shared (e.g., kitchen, living room, laundry room). This prevents space conflicts and helps clarify access boundaries.

2. Rent, Deposit, and Fee Schedules

Specify the exact monthly rent amount, payment deadlines, acceptable transfer methods, and security deposit terms. Security deposits for room rentals are subject to state laws limiting maximum amounts and regulating return timelines.

3. Division of Utilities and Common Costs

Outline how utility costs (electricity, gas, water, internet) will be divided among household occupants. Common approaches include equal splits, prorated splits based on room sizes, or flat monthly utility fees.

4. Attaching the Roommate House Rules

Include your household agreements—such as cleaning schedules, guest limitations, quiet hours, and parking assignments—directly as an addendum to the lease. This ensures house expectations are legally acknowledged by all signing parties.
