Your spare bedroom has been a guest room, an office, and a place where boxes go to be forgotten. Now you want it to pay rent. Renting out a room in your house can work three different ways, and the one you choose decides almost everything after it: the permits, the taxes, the insurance call, and how hard it is to ask someone to leave.
Three Ways to Rent Out a Room, Compared
Most advice treats renting out a room as one job. It is really three:
- A long-term roommate, sometimes called a lodger, who stays for months or years on a written agreement.
- Short stays on Airbnb, where guests book your private room by the night.
- A mid-term renter who takes a furnished room for 30 days or more: travel nurses on short contracts, interns, or people between leases.
Platform figures come from Airbnb's service fee page and Furnished Finder's 2026 pricing notice (both as of November 2026). Airbnb says it is moving all home hosts to its single host-only fee, which most hosts pay at 15.5%, and phasing out the older 3% split fee. For a long-term roommate, the cost depends on the channel; our page on where to list a room compares them side by side.
Which way earns the most?
Short stays can earn more per booked night, but only if the nights get booked. A quick break-even check: say a long-term roommate would pay $900 a month. After a 15.5% host fee, you would need about $1,065 a month in Airbnb bookings to match it, or roughly 17 nights at $65, before laundry, supplies, and the hours spent turning the room over. Furnished Finder charges hosts $199 a year per listing, about $17 a month, and takes no booking commission, but the room can sit empty between renters.
Renting Out Your Room in 7 Steps
These seven steps apply to all three models. The details change; the order does not.
Step 1: Pick Your Rental Model
Three questions settle it: how often are you home, how much contact do you want, and how long are you willing to commit the room?
- Choose a long-term roommate if you want predictable rent and can share a kitchen with the same person every day.
- Choose short stays if you travel often, want the room back for family visits, or want the option to stop at any time. Budget real hours for cleaning and guest messages.
- Choose mid-term if you live near a hospital, a university, or a large employer and want fewer turnovers without a years-long commitment.
Step 2: Check Local Rules and Your Lease
Before you write a listing, find out what your home is allowed to do. Five places to look:
- Your lease, if you rent. Renting out a room in a place you lease is subletting, and many leases ban it without the landlord's written consent. Our guide to subletting your room covers how to ask.
- HOA or condo rules. Covenants can cap occupants or ban stays shorter than a set number of days.
- Short-term rental laws. New York City's Local Law 18 requires hosts to register with the Office of Special Enforcement, live in the home with their guests, and host no more than two guests at a time, and booking platforms cannot process stays for unregistered hosts (NYC Office of Special Enforcement, as of November 2026). Los Angeles requires home-sharing registration for a primary residence and caps short stays at 120 days a year unless you hold an extended registration (LA City Planning guidelines, as of November 2026).
- The 30-day line. Many short-term rules stop at 30 days, but cities draw the line differently. New York City treats a 30-night stay as permanent occupancy (NYC host FAQ), while Los Angeles counts 30 days or less as short-term, so a mid-term stay there needs to run longer than 30 days.
- The bedroom itself. The 2021 International Residential Code requires every sleeping room to have an emergency escape opening of at least 5.7 square feet (5.0 at grade level) with a sill no higher than 44 inches, plus a smoke alarm in the room (ICC, IRC 2021 sections R310 and R314). Local codes vary, but a windowless bonus room is a poor bet as a bedroom.
Step 3: Call Your Insurer
Many homeowners policies are built on the standard ISO HO-3 form, and three of its clauses matter the moment someone pays you rent. From the sample HO-3 form the Insurance Information Institute hosts (2000 edition; your insurer's current edition may differ):
- Liability stops at two roomers. The business exclusion does not apply when part of your home is rented as a residence, unless the household takes in more than two roomers or boarders. One or two renters can keep your liability coverage; a third can put it at risk.
- Their belongings are not covered. "Property of roomers, boarders and other tenants" is excluded unless the renter is related to you. Your renter needs their own policy, and our renters insurance guide for roommates explains who covers what.
- Theft from the rented room is excluded. Theft coverage does not apply to the part of your home you rent to someone who is not an insured on your policy.
Short stays add another layer. In 2017, ISO added a home-sharing exclusion and a set of endorsements that buy coverage back; a current example is the broadened home-sharing host form, HO 06 63 (PropertyCasualty360 FC&S analysis, as of November 2026). Airbnb's AirCover for Hosts includes $3 million in host damage protection and $1 million in host liability insurance (Airbnb, as of November 2026). Airbnb's own terms say the damage protection terms "are not an insurance contract," and a damage request is due within 30 days of the guest's checkout (Airbnb Host Damage Protection terms).
Make the call before you list, and get the answer in writing. A simple script: "I plan to rent one bedroom to a long-term roommate (or to short-term guests, or to a furnished renter for 30 days or more). Does my policy cover that, and which endorsement do I need?"
Step 4: Price the Room From Local Comps
Start with what similar rooms near you ask. SpareRoom's Q3 2026 US rental index, built from asking rents in room-offered ads, put the average room at $1,543 a month in New York (a record), $1,380 in the San Francisco Bay Area, $1,327 in Los Angeles, $1,273 in Boston, and $1,026 in Chicago. San Antonio was the lowest of the 26 metros it tracks, at $756 (SpareRoom Q3 2026 index, as of November 2026).
Then adjust from your local average:
- Push it up for a private bathroom, furniture, parking, included utilities and Wi-Fi, or a lock on the bedroom door.
- Bring it down for a bathroom shared with you, strict house rules, a long commute, or no in-unit laundry.
Decide utilities before you post. A flat monthly amount is simpler than splitting every bill, and our breakdown of utilities with roommates shows both setups. Deposits have limits too: California caps most security deposits at one month's rent, with a two-month exception for small individual landlords (Cal. Civ. Code 1950.5, as of November 2026). Our roommate security deposit guide covers the rest.
Step 5: Get the Room Ready
- Clear it out. Empty the closet and at least two drawers. Renters notice when they are moving into your storage.
- Match the room to the model. Mid-term renters expect a fully furnished room: bed, desk, linens, towels, and reliable Wi-Fi. Short-stay guests also need a smart lock or lockbox and a cleaning routine you can repeat between every booking.
- Photograph it in daylight. Shoot from a doorway corner to show the whole room, then add the bathroom and kitchen they will share.
- Write the house rules now. Quiet hours, kitchen shelves, cleaning, smoking, pets, parking, and overnight guests. A clear guest policy heads off a common fight before it starts.
Step 6: List and Screen Applicants
Where you post depends on the model: Airbnb for nightly stays, Furnished Finder and similar sites for stays of 30 days or more, and roommate sites, local groups, and your own network for long-term renters. A roommate ad that filters spares you fifty "is this still available?" messages.
Fair housing rules still reach your wording. The federal Fair Housing Act exempts an owner who lives in a building of up to four units from most of its rules, but not from its ban on discriminatory ads (42 U.S.C. 3603). For a room inside your own home, the Ninth Circuit, which covers California and eight other Western states, held in 2012 that the Act does not apply to choosing who shares your living unit (Fair Housing Council v. Roommate.com). A 1995 HUD guidance memo adds that a gender-specific roommate ad can still create liability if the space is really a separate unit without shared living areas (HUD memo, archived copy). State and local laws can be stricter, so describe the home and the household rather than the person: "quiet house, no smoking, shared kitchen, early risers."
Then screen every applicant the same way: photo ID, proof of income, a prior landlord reference, and a background or credit check with written consent. Our roommate screening checklist puts those in order.
Screening tells you whether someone pays rent. It says little about whether you can share a bathroom at 7 a.m. Ask about sleep schedules, guests, cleaning, and noise before the tour, or have both of you take a roommate compatibility quiz and compare answers. Tools like CoHabby show those stated habits before you meet, so a mismatch shows up before anyone signs.
Step 7: Sign a Written Agreement
A room rental agreement should cover:
- Rent, due date, and any late fee
- Deposit amount and what it covers
- Utilities: included, flat, or split
- The room itself and which spaces are shared
- House rules: guests, quiet hours, smoking, pets, parking
- When you can enter the room, and with how much notice
- How either side ends it, and the notice period
Our roommate agreement guide includes a quick-start template you can adapt for a renter in your home.
Then find out whether you have a tenant or a lodger. A guest who books two nights leaves at checkout. Someone who has lived in your home for months may have tenant rights, even in your spare room, depending on your state. California has a specific shortcut: if you rent to a single lodger in a home you own and live in, written notice of one rental period ends the arrangement, and the lodger can then be removed as a trespasser (Cal. Civ. Code 1946.5, as of November 2026). Take in a second lodger and the shortcut no longer applies. New York goes the other way: removing someone who has lawfully lived in your home for 30 consecutive days without a court order is a misdemeanor that can carry a civil penalty of $1,000 to $10,000 (N.Y. RPAPL 768). Everywhere else, plan for a court process, and read our guide to evicting a roommate before you need it.
Taxes on Room Rental Income
Room rent is rental income. Most people renting a room in their home report it on Schedule E; if you provide substantial services such as regular cleaning or maid service, it moves to Schedule C (IRS Publication 527, 2025 edition, as of November 2026). Heat, light, and trash collection do not count as substantial services.
- Split shared costs. You can deduct the rented room's share of expenses using any reasonable method, usually rooms or square footage. The IRS example: a 180-square-foot room in an 1,800-square-foot house is 10%, so $60 of a $600 heating bill.
- The under-15-days rule. If you use the home yourself and rent it out for fewer than 15 days in the year, you do not report that rent and do not deduct rental expenses (IRS Topic 415). That can cover a room rented during one big local event; it does nothing for a long-term roommate.
- Form 1099-K. Payment apps and online marketplaces send one only when your payments top $20,000 across more than 200 transactions (IRS, as of November 2026). No form does not mean no tax.
- Selling later. If the rented room is inside your home, you do not need to split the gain when you sell, but depreciation claimed after May 6, 1997 is taxed at sale (IRS Publication 523).
- Occupancy tax on short stays. Texas applies its 6% state hotel occupancy tax to homeowners who rent rooms, but a guest who stays 30 or more consecutive days becomes an exempt permanent resident (Texas Comptroller). Pennsylvania's 6% hotel occupancy tax applies to home-sharing stays under 30 days (Pennsylvania Department of Revenue). Airbnb collects and remits occupancy taxes in many US places, but other tax obligations stay with you (Airbnb).
This is general information, not tax advice; a tax preparer can run your numbers before the first rent payment arrives.
Pick the model, make two calls (city hall and your insurer), and put everything in writing. What is left is finding the right person, and that part decides whether the spare room feels like income or like a second job. Our fit-first guide to renting a room in your home covers that side.
Frequently Asked Questions
Can I rent out one room in my house?
Yes, in most places. Homeowners can usually rent a single room to a long-term roommate, but HOA covenants, local occupancy limits, and short-term rental laws can restrict it. If you rent your home, get your landlord's written consent first.
Do I need a license to rent a room in my house?
Usually not for a long-term roommate, though a few cities register or license rentals more broadly, so check yours. Short stays are different: New York City requires hosts to register with the Office of Special Enforcement, and Los Angeles requires home-sharing registration and caps short stays at 120 days a year without an extended registration.
Is income from renting a room taxable?
Yes. Rent from a room in your home is rental income, usually reported on Schedule E, and you can deduct the share of expenses that belongs to the rented room. The exception is a home you rent out for fewer than 15 days in a year, which you do not report.
What is it called when you rent out a room in your house?
The renter is usually called a lodger, roomer, or boarder; a boarder traditionally gets meals too. Buying a home with plans to rent out rooms to cover the mortgage is often called house hacking.
