Renting Out a Room in Your House: A Landlord’s Guide

Renting out a room in your house can help offset housing costs and generate additional income. But sharing your home with a renter is not quite the same as renting out a separate apartment or single-family property.

The legal relationship can depend on where you live, how the home is set up, whether you also occupy the property, and the terms of the agreement. A person renting a room may be described as a tenant, roommate, lodger, boarder, or licensee depending on the jurisdiction.

For simplicity, this guide uses the neutral term renter. That is not intended to define the person’s legal status.

How to Rent Out a Room in Your House

A practical room-rental process usually looks like this:

1. Check whether you can legally rent the room.
2. Prepare the room and shared areas.
3. Confirm your insurance and mortgage or HOA requirements.
4. Set a competitive rent.
5. Advertise the room.
6. Screen applicants using consistent, lawful criteria.
7. Sign a written room rental agreement.
8. Track rent, expenses, documents, and taxes.

1. Check State and Local Rules

Before advertising the room, check the rules that apply to your property.

Depending on the location and property type, you may need to consider:

• State landlord-tenant laws.
• City or county rental rules.
• Zoning and occupancy limits.
• Building, fire, and safety requirements.
• Licensing or inspection requirements.
• Condo or homeowners association rules.
• Mortgage restrictions.
• Rules that apply specifically to owner-occupied homes or shared housing.

A room-rental arrangement can be treated differently from a standard rental where the landlord lives elsewhere.

2. Prepare the Room and Shared Areas

Make sure the room is safe, clean, and suitable for occupation under the rules that apply locally.

Think about both the private room and the shared areas the renter will use. For example:

• Is the room furnished or unfurnished?
• Which bathroom will they use?
• Will they have a separate entrance?
• Which kitchen, laundry, parking, and storage areas are included?
• Are there locks on the bedroom door, and are they permitted under local fire and building rules?
• How will utilities and internet costs be divided?

If you provide furniture or other items, create an inventory and take dated photos before move-in.

3. Check Your Insurance, Mortgage, and HOA Rules

Tell your insurer before renting out part of your home. A standard homeowners policy may not provide the coverage you expect once part of the property is rented, and your insurer may recommend an endorsement or different policy.

Also check any mortgage, condo, or HOA terms that apply to the property. These can impose occupancy or rental restrictions separate from state landlord-tenant law.

4. Set the Rent

Research comparable room rentals in the same area rather than comparing the room with entire apartments or houses.

Factors that can affect the rent include:

• Room size.
• Private vs shared bathroom.
• Furnished vs unfurnished.
• Parking.
• Utilities included.
• Laundry access.
• Storage.
• Location and transport links.
• Shared amenities.

You should also decide in advance how utilities and other shared household costs will be handled.

5. Advertise the Room Clearly

Make it obvious that you are advertising a room in an owner-occupied or shared home, rather than a separate rental unit.

Your listing should explain:

• Monthly rent.
• Deposit, if applicable.
• What utilities are included.
• Furnishings.
• Shared spaces.
• Parking.
• Lease length.
• House rules that applicants should know before applying.

Avoid making legal assumptions about who you may or may not select based simply on the fact that you will share the home. Fair Housing rules for owner-occupied and shared housing are more nuanced than the previous version of this guide suggested.

6. Screen Applicants Consistently

A room renter will share your home, so compatibility matters. At the same time, screening should be based on lawful and consistently applied criteria.

Depending on what is permitted where you live, you might consider:

• Income and ability to pay rent.
• Rental history.
• References.
• Credit history.
• Relevant background-screening information.
• Whether the applicant agrees to the documented house rules.

If you use a consumer report or third-party tenant screening service, separate federal and state requirements may also apply.

7. Use a Written Room Rental Agreement

Even where an oral agreement may be legally possible, a written agreement makes the arrangement much clearer.

The agreement should identify the space being rented and explain how the renter may use shared areas.

Consider covering:

• Rent amount and due date.
• How rent is paid.
• Length of the arrangement.
• Deposit terms.
• Utilities and shared bills.
• Kitchen and laundry use.
• Parking.
• Guests.
• Smoking.
• Pets.
• Cleaning responsibilities.
• Shared storage.
• Quiet hours.
• Private areas.
• When the owner may need access to the rented room.
• How either party can end the arrangement, subject to applicable law.

A lease or room rental agreement cannot override rights or notice requirements imposed by state or local law.

8. Track Income and Expenses

Keep records of:

• Rent received.
• Deposits.
• Utilities paid by you.
• Repairs and maintenance.
• Insurance.
• Advertising.
• Furnishings and supplies.
• Relevant household expenses.
• Rental agreements, notices, receipts, and communications.

Fair Housing Rules When Renting Out a Room

At the federal level, the Fair Housing Act generally prohibits housing discrimination based on race, color, national origin, religion, sex, familial status, and disability. Federal law also contains exemptions for certain owner-occupied and small-property situations. However, those exemptions are technical, and the Act's advertising provisions are treated differently from some of its other prohibitions.

There is also federal case law specifically addressing shared living arrangements. In Fair Housing Council of San Fernando Valley v. Roommate.com, the U.S. Court of Appeals for the Ninth Circuit held that the federal Fair Housing Act did not apply to roommate selection within a shared living unit.

That decision should not be presented as a nationwide rule. It is Ninth Circuit precedent, and state and local fair-housing laws can provide broader protections.

The safer general approach is:

• Do not assume that owner-occupancy gives you a blanket exemption from Fair Housing law.
• Use neutral language in advertising unless you have confirmed a lawful exception that applies to your specific arrangement.
• Apply screening criteria consistently.
• Check state and local anti-discrimination laws. They can provide broader protections, cover additional protected classes, and use different owner-occupied or shared-housing exemptions from federal law. A federal exemption therefore does not automatically mean the same conduct is permitted under state or local law.

Privacy and Access to the Rented Room

There is no single nationwide rule requiring exactly 24 hours' notice before a landlord enters a rented room.

Entry and privacy rules vary by state, and the renter's legal status can matter. Some jurisdictions have statutory notice periods. Others use a reasonableness standard or distinguish between tenants and people occupying a room in an owner-occupied home.

As a practical matter:

• Treat the rented bedroom as the renter's private space.
• Explain access rules in the written agreement.
• Avoid entering without permission except where the law or a genuine emergency permits it.
• Check the state and local rule before relying on a particular notice period.

House rules can create clear expectations, but they should not attempt to waive rights that the renter has under applicable law.

Security Deposits for Room Rentals

You may be able to collect a security deposit, but the rules are highly state-specific.

Depending on the state, the law may regulate:

• The maximum deposit.
• Where the deposit must be held.
• Whether interest is required.
• Required receipts or disclosures.
• Permitted deductions.
• Itemized statements.
• The deadline for returning the remaining deposit.

There is no nationwide 21-day deadline for returning a security deposit.

Use the rules for the state where the property is located rather than relying on a single national timeline.

Ending a Room-Rental Arrangement

The previous version of this guide suggested that an owner-occupier could generally give notice and then have a renter removed for trespassing if they did not leave. That is too broad for a national guide.

The correct process depends on:

• The state and city.
• Whether the occupant is legally a tenant, lodger, licensee, roommate, or another category.
• Whether there is a fixed-term or periodic agreement.
• Why the arrangement is ending.
• The applicable notice requirements.
• Whether a court process is required.

Some jurisdictions do provide different procedures for certain owner-occupied room rentals, but those rules are not uniform.

Do not change the locks, remove belongings, shut off utilities, or otherwise attempt a self-help removal unless local law clearly permits the specific action.

If the renter does not leave after valid notice, check the procedure required by your state before taking the next step.

Taxes When Renting Out a Room in Your House

Rental income is generally taxable, but renting part of the home you live in requires more care than simply deducting every household expense.

The IRS says that when an expense relates to both the rental part and the personal part of your home, you need to divide the expense between the two.

IRS Publication 527 says you can use any reasonable allocation method. Common approaches include:

• The number of rooms, where the rooms are roughly comparable in size.
• The square footage used for rental purposes.
• For some shared costs, such as water, the number of people using the service may be reasonable.

For example, if the rented bedroom represents 10% of the home's floor area, 10% may be a reasonable rental allocation for certain whole-home expenses.

Expenses that apply only to the rented room or rental activity may be treated differently from shared household expenses. Depending on the facts, rental expenses may include items such as:

• Advertising.
• Repairs and maintenance.
• Insurance.
• Utilities.
• Mortgage interest.
• Property taxes.
• Supplies.
• Depreciation on the rental portion of qualifying property.

The deductible amount and reporting treatment depend on the circumstances, including the extent of personal use.

The Less-Than-15-Day Rule

There is also a special federal rule for very short rental use.

If you use the dwelling as a home and rent it for fewer than 15 days during the tax year, the IRS generally says you do not report that rental income and do not deduct rental expenses from that activity.

For an ongoing room rental, this exception normally will not apply.

Rental real-estate income and expenses are commonly reported on Schedule E (Form 1040), although different reporting rules can apply in some circumstances.

Room Rental Agreement Checklist

Rather than creating a separate rule for every possible household issue, agree on the practical details before move-in and put the important ones in writing.

A useful checklist includes:

• Rent.
• Deposit.
• Utilities.
• Shared spaces.
• Guests.
• Pets.
• Smoking.
• Laundry.
• Parking.
• Cleaning.
• Food and kitchen storage.
• Quiet hours.
• Privacy.
• Access to the rented room.
• Notice for ending the arrangement.

The aim is to reduce ambiguity while leaving legal matters such as statutory entry rights, deposit rules, and termination procedures to the law that applies in your jurisdiction.

Frequently Asked Questions

Do I need a lease to rent out a room in my house?

The legal requirement varies by state and by the type and length of the arrangement. Even where a written agreement is not mandatory, putting the rent, shared-space rules, deposit terms, and other key expectations in writing can help prevent disputes.

Can I choose who rents a room in my home?

You can screen applicants, but discrimination rules for shared and owner-occupied housing are complex. Federal exemptions and case law do not create a simple nationwide rule, and state or local laws may be broader. Use neutral advertising and consistent screening criteria unless you have confirmed that a specific exception applies.

Does a renter in my house have the same rights as a tenant in a separate apartment?

Not necessarily. The occupant's legal status and rights can depend on state law, the living arrangement, and the agreement. Some states distinguish between tenants, lodgers, roommates, and licensees.

How much notice must I give before entering a rented room?

There is no universal U.S. rule requiring a particular number of hours. Check the law that applies in your state and city and set clear privacy expectations in the agreement.

How long do I have to return a room renter's security deposit?

The deadline varies by state. There is no nationwide 21-day rule. Check your state's security-deposit law for the applicable deadline, deductions, and itemization requirements.

Do I need to report income from renting out a room?

Generally, rental income must be reported. However, the IRS has special rules for homes that are also used personally, including allocation of shared expenses and an exception when a home is rented for fewer than 15 days during the year.
