Renting out a room in your home can be a great way to earn extra income and put unused space to good use. Whether you’re helping cover your mortgage payments or just want to supplement your budget, opening your doors to a tenant can provide valuable financial relief. But it’s important to approach this arrangement with care and planning. You’re not just gaining a housemate — you’re entering into a legal and financial relationship that comes with real responsibilities.
Before you start interviewing interested renters, it’s important to understand what you’re getting into. Renting out a room in your house means you’re becoming a landlord, and you’ll need to follow both local laws and federal housing guidelines. It’s more than just handing over a key and collecting rent — you’re legally responsible for providing a habitable living space, maintaining clear house rules, and setting fair rental terms.
If done right, renting out a room can be a win-win situation. You generate rental income, your tenant gets an affordable living space, and your home’s unused space becomes a source of value.
A clear and detailed lease agreement is one of the most important tools in a successful room rental. Even though you’re only renting part of your property, you should treat this like any other landlord tenant relationship. Don’t rely on verbal agreements or casual arrangements. Put everything in writing.
A proper lease agreement should outline key terms such as:
Having these items in writing protects both you and the tenant. It prevents confusion, helps enforce house rules, and provides legal backing if issues arise. You may also want to include a clause about late fees and the process for resolving disputes.
Consider using a room rental lease agreement template from a trusted legal resource or ask a housing counselor for help. For more detailed guidance, check with your local housing authority to ensure your lease complies with city and state regulations.
Before you legally rent out a room, you must research your city’s zoning rules and landlord requirements. Some cities limit how many unrelated people can live in a single home. Others have rules about whether homeowners can offer room rentals at all. In certain areas, you may be required to register the rental or apply for a business license.
Be sure to understand:
To avoid fines or legal trouble, check with your city’s zoning office or housing department. You can also visit Innago for helpful resources on rental laws by state.
Once you become a landlord, you must follow your state’s landlord tenant laws. These laws outline your legal responsibilities and protect the rights of your tenant. For example, you’ll need to give proper notice before entering their space, return security deposits within a set time frame, and make timely repairs.
Common rules under landlord tenant laws include:
If you’re unsure what laws apply to you, connect with a HUD-approved housing counselor at Credit.org. They can walk you through the legal side of room rental and help you stay compliant.

Sharing a home with someone new requires clear boundaries and strong communication. A well-written set of house rules can help set expectations from day one and avoid unnecessary conflict. Even with a lease agreement in place, house rules can address the finer details of day-to-day living.
Some examples of house rules include:
Make sure these rules are communicated clearly before your tenant moves in. You might even want to walk through the home and go over any personal space boundaries, like whether the tenant has access to a private bathroom or private office.
Once you rent out a room in your house, you’re more than just a homeowner — you’re now in a landlord tenant relationship. This new role means you have specific legal duties, even if your tenant is someone you already know. Personal relationships don’t cancel out legal obligations.
To manage this relationship professionally:
Treating your rental like a business helps keep the landlord tenant relationship stable and positive. Remember, even if you’re living under the same roof, your tenant still has the right to privacy and fair treatment under the law.
When you think about house renting, most people picture leasing out an entire property. But when you’re only renting a room, the arrangement is a bit different. You still need to consider factors like property value, how much rent to charge, and what your responsibilities are as the property owner.
Keep in mind that house renting — even just one room — has potential impacts on:
If you’re using your home as a primary residence, make sure you’re not violating any clauses in your mortgage loan. It’s a good idea to talk with your lender before proceeding. If your insurance provider doesn’t cover room rentals, you may need to purchase landlord insurance to stay protected.

Screening tenants is one of the most important steps in renting out a room. A good tenant can make the process smooth and stress-free. A bad one can turn your home life upside down.
Start by conducting a basic background and credit check. This step helps you avoid prospective tenants with a history of eviction, late payments, or criminal behavior. Here’s what to consider:
There are services that will run credit and background checks for a small fee. Be sure to get written permission from the tenant before requesting their information. And keep in mind that you must follow the Fair Credit Reporting Act when using this data to make rental decisions.
A clear tenant screening process also shows potential renters that you’re serious and professional. This can attract responsible individuals who respect the structure you’re putting in place.
Before you hand over a key, make sure you’re legally allowed to rent out a room in your house. Some homeowners run into trouble when they assume they don’t need approval, especially if it’s an informal arrangement.
To legally rent a room, you may need:
Many municipalities also have restrictions on how many tenants can live in a home, how many unrelated people can share a residence, or whether basement rooms are permitted as living spaces. Some areas have strict rules about what qualifies as a habitable living space.
It’s best to contact your local zoning board or housing department before listing the room. You can also explore legal information for your area at Nolo.com, a trusted source for landlord legal issues.
Setting the right rent price is key to attracting quality tenants and generating income. But how do you decide how much rent to charge?
Start by researching similar room rental listings in your area. Use rental listing sites like Craigslist, Zillow, or Roomster to compare prices. Make sure you’re looking at rooms of similar size, in similar neighborhoods, and with comparable amenities like a private bathroom, access to laundry, or off-street parking.
Consider the following:
You’ll also want to be realistic. Charging too much will drive away interested renters. Charging too little may attract the wrong tenants or leave you short financially.
For example, if your total monthly mortgage is $2,400 and you plan to rent out a large master bedroom with a private entrance and bathroom, $800–$1,000 may be fair depending on local demand and amenities offered.
Always make sure your rent price aligns with local landlord tenant laws. In rent-controlled areas, you may be limited in how much you can charge or increase the rent over time.
One of the most appealing reasons to rent out a room is the opportunity to generate extra income. Whether you’re looking to supplement your monthly budget, save for a financial goal, or simply put unused space to work, room rental can be a smart financial strategy.
That said, you must remember: rental income is taxable. Even if it’s just a room in your house, the money you collect must be reported on your federal income taxes. Depending on how your lease is structured, some of your property-related expenses may be deductible. This might include:
To manage your taxable income properly, keep good records. Document all payments received and any expenses related to the room. If your lease includes shared spaces like a kitchen or laundry room, talk to a tax professional to see how to calculate deductions accurately.
To learn more about how to handle rental income, see the IRS guide on residential rental property.
Finding the right tenant begins with attracting the right audience. You can post your listing on popular rental listing sites, social media platforms, or bulletin boards in community centers. In your ad, be clear about:
As inquiries come in, screen for serious and responsible renters. You may receive messages from many interested renters, but not all of them will be a good fit. Use a short phone or video interview to get to know the person and explain the living situation.
Key questions to ask prospective renters:
Being upfront about your expectations helps avoid problems later. Don’t forget: Fair Housing laws prohibit discrimination based on race, religion, national origin, disability, family status, or sex.
Before your tenant moves in, contact your insurance provider. Most standard homeowners insurance policies don’t fully cover situations where you’re acting as a landlord. Renting out part of your home may be considered a business activity, which might require a policy change.
Ask your insurance provider:
Landlord insurance typically covers:
Some homeowners also require the tenant to get renter’s insurance. This protects the tenant’s personal belongings and may reduce the chance of disputes in case of damage or loss. Read more about renter's insurance from the Insurance Information Institute.
Keeping your insurance updated is part of your responsibility as a property owner. It helps protect both you and your tenant — especially in the event of an accident or major issue.
Before advertising your rental, take time to evaluate the space you’re offering. Is it a spare room, a basement apartment, a private office converted to a bedroom, or just an unused corner of the house? Think about what will make it livable and appealing to renters.
What renters often look for:
If possible, offer a private space within the home. This can allow both you and your tenant to feel more comfortable and maintain boundaries. Some landlords add a mini fridge or microwave to reduce tension over shared kitchen space.
Rooms with separate entrances, private bathrooms, or kitchenette setups can also command higher rent and attract more qualified prospective tenants.
Also, make sure your space meets legal standards for a habitable living space, which includes proper ventilation, windows, emergency exits, and working smoke detectors.
Tenant screening is more than just a quick conversation or handshake. As a landlord, it’s your job to find a tenant who’s reliable, responsible, and a good fit for your home. That means taking a professional and consistent approach with every applicant.
Your screening process should include:
Look for red flags like prior evictions, inconsistent income, or negative feedback from former landlords. But also listen to your instincts. Someone may look great on paper but could still clash with your home’s atmosphere or household culture.
You are legally allowed to screen applicants, but you must follow anti-discrimination laws. Treat every applicant equally, and make decisions based on objective criteria like income, credit, and rental history.
Resources like Experian’s tenant screening services can help small-scale landlords safely and legally screen tenants online.
Even if you’re renting out just one room, you’re now responsible for maintaining a safe and habitable property. This includes fixing plumbing issues, keeping the heat working in the winter, and responding to complaints or needed repairs in a timely manner.
Some essential maintenance responsibilities include:
You don’t need to be a full-time property manager, but you do need to act quickly when issues arise. If you’ll be unavailable for extended periods, you should designate someone else who can handle emergency situations or coordinate repairs.
If managing these responsibilities becomes overwhelming, consider hiring a small-scale property management company to help with rent collection, maintenance, and tenant communication.
If you collect money for a room rental, you’re earning rental income, and the IRS expects you to report it. This is true even if the rental arrangement feels informal or temporary. Fortunately, you can deduct some of the expenses related to the rented space.
Typical deductible expenses include:
Use IRS Publication 527 to calculate these deductions correctly. If you’re only renting out one room in your house, you’ll usually base deductions on the square footage of the rented area. For example, if your tenant’s room is 20% of your home’s square footage, you may be able to deduct 20% of eligible expenses.
Make sure you pay taxes on all rental income and consult a tax advisor if you’re unsure how to report or deduct correctly. Poor record-keeping or failure to report income can result in penalties or audits.
Once your tenant decides to move out, it’s time to do a final walk-through of the rented space. This gives you an opportunity to check for damage, review any cleaning expectations, and ensure the tenant didn’t remove shared property.
During the final walkthrough:
By handling the move-out process carefully, you reduce the risk of disputes and maintain a professional relationship. You should also return the security deposit within the time frame required by your state, along with an itemized list of any deductions.
