Roommate Agreement Guide: What to Cover Before You Move In Together

Living with roommates dramatically lowers your rent burden — the number one reason people do it. But shared living without clear agreements is a recipe for conflict. Most roommate disputes aren't about big issues; they're about small things that compound over time: who buys dish soap, whose turn it is to clean the bathroom, what "quiet hours" means. A good roommate agreement addresses all of it before anyone moves in.

Using our rent affordability calculator to split rent by income is a good starting point — from there, this guide helps you build the full agreement that protects everyone.

Why a Written Roommate Agreement Matters

A verbal agreement is difficult to enforce and easy to misremember. A written and signed roommate agreement:

• Creates a clear record of what everyone agreed to
• Forces important conversations to happen before problems arise
• Provides evidence if you end up in small claims court
• Reduces misunderstandings by making expectations explicit
• Makes it easier to enforce consequences when someone violates the terms

Section 1: Rent and Financial Responsibilities

Money is the most common source of roommate conflict. Nail down every financial detail explicitly.

How to Split Rent

Three common approaches:

• Equal split: Each person pays the same amount. Fair when rooms are similar in size. Simple to calculate and remember.
• Room-size split: Calculate each room's share of total square footage and allocate rent proportionally. The person in the larger room with the private bathroom pays more.
• Income-based split: Each person pays a percentage of the total rent proportional to their income. Less common but prevents situations where lower-earning roommates are stretched while higher earners have abundant disposable income.

Utility Splits

Specify who pays each utility and how costs are divided:

• Electric and gas: Equal split or based on usage
• Internet: Whoever sets up the account; others pay their share directly to that person
• Streaming services: Which services are shared, who holds the accounts, how costs are divided
• Renter's insurance: Each person should have their own policy, OR specify who holds the shared policy and how others reimburse them

Shared Household Expenses

Specify how common household items are bought:

• Cleaning supplies, toilet paper, dish soap, trash bags — equal contribution to a shared fund?
• Kitchen staples (oil, condiments, spices) — shared or individual?
• Shared subscriptions

Payment Method and Deadlines

Specify how and when each roommate pays their share. Apps like Splitwise, Venmo, or Zelle make transfers easy. Set a deadline (e.g., "all roommates pay their share to the lease-holder by the 1st of the month; the lease-holder submits full rent to landlord by the 3rd").

Section 2: Cleaning and Household Maintenance

Cleanliness differences are the #1 day-to-day source of roommate tension. Setting expectations explicitly at the start — not after someone is already annoyed — prevents most issues.

Common Areas

Specify who is responsible for:

• Kitchen (dishes, counters, stove, refrigerator)
• Bathrooms (if shared)
• Living room (vacuuming, dusting)
• Floors/hallways

Options: rotating weekly schedule, assigned zones, or hire a cleaning service and split the cost.

Cleaning Standards

Define "clean" explicitly. Does "clean the kitchen" mean wipe the counters or include the inside of the microwave? What's the maximum time dishes can sit in the sink? Setting these expectations removes ambiguity.

Private Spaces

Each person is responsible for their own bedroom. Specify whether common area standards apply to personal rooms when guests are present.

Section 3: Guests and Overnight Visitors

Guest policies prevent a significant category of conflict, especially when a guest informally becomes a long-term live-in partner without contributing to rent or utilities.

• How many consecutive nights can a guest stay without discussion? (Common answer: 3–7 nights)
• What is the process for a guest staying longer? (Notify all roommates? Pay into utilities?)
• Are overnight guests limited to certain areas?
• How does the agreement address a partner who effectively moves in?

Section 4: Quiet Hours and Lifestyle

Night owl vs. early riser conflicts are extremely common. Establish baseline expectations:

• Quiet hours (e.g., 10pm–8am on weekdays, midnight–9am on weekends)
• Party/gathering policy: How much notice is required? What time do gatherings end?
• Smoking and substances: Smoking allowed inside? On the balcony?
• Pet policy: Does any roommate have or plan to have a pet? Allergies?
• Temperature: Who controls the thermostat and at what range?
• Noise (TV, music, phone calls) in common areas

Section 5: Kitchen and Food

• Is food shared or individual? (Most households: individual, clearly labeled)
• Which pantry/refrigerator shelves belong to whom?
• Can roommates use each other's food? Under what circumstances?
• Who takes out the trash and how often?

Section 6: Privacy and Personal Boundaries

• Knocking before entering each other's rooms
• Privacy around belongings (tools, car, equipment)
• Using each other's personal items (borrowing policy)
• Working from home: expectations around noise, video calls, shared workspaces

Section 7: Dispute Resolution

Include a process for resolving disagreements before they escalate:

1. Raise the issue directly with the roommate within 48 hours
2. If unresolved, hold a house meeting with all roommates present
3. If still unresolved, consider bringing in a neutral mediator (friend, RA, or local mediation service)
4. If the conflict cannot be resolved and violates the agreement terms: notice period for the offending roommate to cure the violation or arrange to leave

Section 8: Move-Out Procedures

• Required notice before moving out (typically 30–60 days)
• Process for finding a replacement roommate (who has final say?)
• How the security deposit is handled if one roommate leaves early
• Final cleaning responsibilities

For more on what happens at move-out, see our guide on how to dispute a security deposit — applicable when roommates disagree on who caused damage.

Signing the Agreement

All roommates should sign and date the agreement and each keep a copy. For important decisions, email confirmation of verbal agreements creates an additional timestamped record.
