Roommate Chore & Utility Cost-Sharing Agreement

Roommate Chore & Utility Cost-Sharing Agreement: a practical guide

A Roommate Chore & Utility Cost-Sharing Agreement records how people sharing a home will divide household tasks and utility costs. It gives the roommates a written reference for their arrangements and expectations.

What it's for

Roommates can use this document when they want to agree on who handles recurring chores, how shared supplies are paid for, and how bills for services such as electricity, water, or internet are divided. It is useful when people move in together or when existing housemates want to clarify an arrangement that has become uncertain.

Write down practical details, such as which tasks are shared, how often they are done, how each person’s share of a bill is calculated, and how payments are made. If the main purpose is to set or change rights to occupy the home, rent, or lease terms, a residential lease or room sublease may be a better fit; this agreement is focused on household tasks and shared costs.

Who uses it

• Roommates sharing a home who want a regular chore schedule.
• People moving into a shared home who want to discuss costs and responsibilities before settling in.
• Housemates who split utility bills but want a clear calculation and payment routine.
• A tenant and a housemate who want to record how shared chores and household expenses are handled.
• Several people sharing a home who want to agree how common areas and supplies are maintained.

Terms to decide on

People and shared home

Identify each side and the home the arrangement covers. If more than one person is included on a side, state who is responsible for that side’s agreed tasks and payments.

Chore list and frequency

Name each task, how often it should be done, and whether it covers a shared area or a particular item. Use specific wording such as “take bins to the collection point on collection day” instead of “handle rubbish.”

Task rotation and missed chores

Say who starts each rotation, when it changes, and how roommates will handle a missed task. Agree how someone can arrange a swap or make up the task, rather than leaving the response open to guesswork.

Utility bills and shares

List which household services are shared and how each person’s portion is worked out, such as an equal split or another agreed method. State what happens if a bill covers a period before or after someone moves in or out.

Bill access and payments

Decide who receives each bill, how roommates can review the amount, when each share is due, and how it will be paid. If one person pays the provider, describe how the others reimburse that person.

Shared supplies and extra costs

Clarify which items count as shared household supplies, how purchases are approved, and how the cost is divided. Distinguish shared items from personal purchases so neither side is expected to pay for something they did not agree to share.

Changes and end of arrangement

Describe how the roommates will discuss changes to chores or cost shares and record any new agreement. State how the arrangement will be handled if a roommate moves out or the household arrangement ends.

Common mistakes

• Writing “split everything equally” without listing which bills or purchases are included. This can lead to different expectations about personal services, shared supplies, or one-time costs.
• Using vague chores such as “keep the kitchen clean.” Agree on the specific task and frequency, including what counts as done.
• Forgetting that utility bills can cover different dates or include charges that vary from month to month. Agree how to handle changing totals and partial billing periods.
• Giving one roommate responsibility for paying bills without stating how the others can see the bill or when they should reimburse that person.
• Assuming a chore schedule will still work when someone is away, ill, or has a different routine. Decide how swaps and missed tasks will be handled.
• Treating this document as a replacement for an arrangement about occupying the home or paying rent. Address those topics in a suitable housing document as well, where needed.

Before you sign

• Read every chore and confirm that its frequency and expected result are clear to both sides.
• Check that each shared bill and the method for dividing it are listed accurately.
• Confirm how bills and shared purchases will be shown to the other roommates and paid back.
• Review the move-in, move-out, absence, and missed-task arrangements together.
• Make sure any extra terms reflect what everyone has discussed and agreed to.
• Check that the names, effective date, and signature blocks are complete and accurate.
• Check the rules where the document will be used if local requirements for signatures, witnesses, notarization, or required wording may apply, or ask a qualified lawyer if a lot is at stake.
