How to Rent Out a Room in Your House: Zoning, Leases, and Taxes

To rent out a room in your house, you need to confirm local zoning and any HOA rules allow it, bring the room up to fire and building code, update your homeowners insurance, follow federal fair housing rules when advertising and screening, sign a written lease, and report the rent on your federal taxes. The order below is the order to work through it, because each step depends on the one before.

Check Zoning and HOA Rules First

Before you spend money on anything else, confirm your property is legally eligible. Municipalities distinguish between single-family residences and rooming houses, and renting a room without the correct zoning designation can trigger daily fines until you correct it. Call your local code-enforcement office and ask directly.

If a homeowners association governs your neighborhood, read the covenants, conditions, and restrictions. Many HOA bylaws prohibit boarders or short-term guests outright, and violations can bring fines, liens against your property, or legal action from the board. Getting written confirmation that a room rental is allowed protects you from expensive surprises later.

Make Sure the Room Meets Code

Any bedroom you rent must meet fire and building code standards. Rules vary by jurisdiction, but most follow the International Residential Code or a close equivalent. The consistent requirements:

A working smoke alarm in every sleeping room and on each floor. Many jurisdictions also require carbon monoxide detectors near sleeping areas if the home has fuel-burning appliances or an attached garage.
An emergency escape window large enough for an adult to climb through. Under the IRC that means a net clear opening of at least 5.7 square feet, a minimum height of 24 inches, a minimum width of 20 inches, and a sill no more than 44 inches above the floor.
At least 70 square feet of floor area and a ceiling height of at least 7 feet over at least half the room.

Some municipalities require a rental inspection or occupancy permit before you can legally rent to anyone, so ask your local building department whether the room qualifies and whether a permit is needed.

Lead Paint Disclosure for Pre-1978 Homes

If your home was built before 1978, federal law requires you to give every prospective tenant an EPA-approved pamphlet on lead poisoning prevention, disclose any known lead paint or hazards, and share any available inspection reports before the lease is signed. The lease itself must include a lead warning statement, your disclosure of known hazards (or a statement that you have no knowledge of any), and the tenant’s signature confirming they received the information. Keep a signed copy for at least three years from the start of the lease.¹ Knowingly failing to disclose can bring civil penalties per violation plus liability for up to three times the tenant’s damages if they are harmed.

What Fair Housing Rules Let You Do

The federal Fair Housing Act makes it illegal to refuse to rent, set different terms, or otherwise discriminate against someone because of race, color, religion, sex, familial status, national origin, or disability.² Owners who live in a building with four or fewer independent units qualify for the “Mrs. Murphy” exemption, which allows personal preferences during tenant selection that would otherwise violate the Act.³

The exemption has a hard limit: the advertising prohibition still applies. Any listing you post, online or otherwise, must avoid language indicating a preference based on a protected class.² Many states and cities add their own protected classes (such as sexual orientation or source of income), so check your local human rights ordinance before you write your ad.

Update Your Insurance Before Anyone Moves In

A standard homeowners policy is designed to cover you and your family, not paying tenants. Most policies exclude or severely limit coverage for injuries or property damage involving a boarder, so if your tenant slips on the stairs and sues, your insurer could deny the claim outright.⁴

Call your agent before the tenant moves in. Depending on your situation you may need a rental endorsement on your existing policy or a separate landlord policy that covers the rented portion of the home. Some insurers offer on-demand coverage that activates only during the rental period, which can lower costs for occasional or short-term rentals.⁴ Encourage your tenant to carry renter’s insurance for their own belongings and personal liability.

Set the Rent, Deposit, and Utilities

Research comparable room listings to set a competitive price. A private bathroom, included parking, or proximity to transit all affect what the market will bear. Decide upfront whether utilities are included or split. A common approach is to divide the total bill by the number of occupants; you can also allocate based on the square footage the tenant uses. Whatever you choose, put it in the lease.

A security deposit protects you against unpaid rent and damage beyond normal wear and tear. Most states cap the deposit at one to two months’ rent, some allow more for furnished rooms, and a handful set no cap at all. Check your state’s rule before setting the amount.

How you return the deposit matters as much as how you collect it. Return deadlines vary but typically fall between 14 and 60 days after move-out, with 30 days the most common. Many states require an itemized written list of any deductions and return of the balance within that window. Some jurisdictions require you to hold the deposit in a separate account or pay interest. Mishandling it can expose you to penalties; in some states a court can award the tenant double or triple the deposit.

Draft a Written Lease

A written lease is your most important protection. Even where state law doesn’t require one for a room rental, a handshake leaves both sides vulnerable. Templates are available through legal service providers and local real estate associations. At a minimum the lease should cover:

Full legal names of the parties and a description of the rented room plus any shared spaces (kitchen, bathroom, laundry, yard).
Start and end dates or a statement that the tenancy is month-to-month, the monthly rent, the due date, and accepted payment methods.
The security deposit amount, what it covers, and the conditions for its return.
Which utilities are included and how shared costs are divided.
House rules: quiet hours, guest policies, pets, smoking, parking, and any limits on common-area use.
Late fees and the grace period. A minority of states cap late fees (often around 5 percent of rent); most only require that the fee be reasonable. The fee must be stated in the lease to be enforceable.
Notice required to end the lease. For month-to-month arrangements most states require 30 to 60 days, though some require as little as 7 days for weekly rentals or as much as 90 days for long-term tenancies.
Your right of entry. Most states require at least 24 hours’ written notice before entering the rented space for non-emergency reasons like repairs or inspections. Emergencies such as a burst pipe or a suspected gas leak typically allow immediate entry.

If your home was built before 1978, attach the signed lead paint disclosure. Both parties should sign and date every page and keep a complete copy.

Screen the Applicant Properly

Start with a written application that collects the applicant’s full legal name, current address, employment information, and authorization to run credit and background checks. Landlords commonly charge an application fee to cover third-party screening; some states cap this fee, so check before setting an amount.

A credit report shows the applicant’s history of paying debts on time; a criminal background check screens for relevant convictions. Many landlords use a gross monthly income of at least three times the rent as a benchmark for affordability, though this is an industry standard, not a legal requirement. For traditionally employed applicants, recent pay stubs and a call to the employer are usually enough. Self-employed applicants can provide bank statements from the past two to three months, recent tax returns, 1099 forms, Social Security benefit letters, or pension statements.

Call former landlords. A credit report tells you about financial reliability, but a previous landlord can reveal noise complaints, lease violations, or property damage that never show up on paper.

Adverse Action Notices Under the FCRA

If you reject an applicant based partly or entirely on information in a credit report or background check, the Fair Credit Reporting Act requires you to send an adverse action notice.⁵ The notice must include the name, address, and phone number of the reporting agency, a statement that the agency did not make the decision, and information about the applicant’s right to dispute the report and request a free copy within 60 days.⁶ Skipping this step can expose you to federal liability, so treat it as mandatory.

Do a Move-In Walkthrough

Once you’ve picked a tenant, collect the first month’s rent and the full security deposit before handing over any keys. Accept cashier’s check, direct bank transfer, or another method that creates a clear record, and wait for the payment to clear.

Before the tenant brings their belongings in, walk through the room together with a written checklist. Document every existing scratch, stain, scuff, and appliance issue, and take dated photographs of each. Both parties sign the completed inspection form and keep a copy. This record becomes the baseline for evaluating damage at move-out and directly affects how much of the deposit you can retain.

Know Whether Your Renter Is a Lodger or a Tenant

In many states, someone who rents a room in a home where the owner also lives is classified as a lodger rather than a traditional tenant, and lodgers generally have fewer legal protections. In some jurisdictions, ending a lodger arrangement requires only a notice equal to one rental period, after which the person becomes a trespasser if they refuse to leave. Tenants, by contrast, can typically be removed only through a formal court eviction. Your state’s landlord-tenant statute determines which rules apply, so look it up before you need to end the arrangement.

When you do end the tenancy, give written notice within the timeframe your lease and state law require. Conduct a move-out inspection using the same checklist from move-in, note any new damage, and return the security deposit (less any lawful, itemized deductions) within your state’s deadline.

Report the Rent on Your Taxes

All rent you collect is taxable income, reported on Schedule E of your federal return.⁷ One exception: if you rent the room for fewer than 15 days in a calendar year, you don’t need to report the income and can’t deduct rental expenses for those days.⁸

Because you also live in the home, you must split expenses between personal and rental use. The IRS allows any reasonable method; the two most common are dividing by the number of rooms or by square footage.⁹ If you rent one room in a five-room house, you can generally deduct 20 percent of shared expenses. Deductible categories include your share of mortgage interest, property taxes, homeowners insurance, utilities, repairs and maintenance to the rental space or shared areas, and depreciation on the rental portion of your home.

Improvements (upgrades that add value or extend the life of the property) can’t be deducted in the year you pay for them; they must be depreciated over time.⁹ Keep receipts for every expense. You can still deduct the personal portion of your mortgage interest and property taxes on Schedule A if you itemize.⁷
