You do not need a federal license to rent out a house, but you very likely need a license or permit from your city or county. Most municipalities require landlords to register the property, pay a fee, and pass a safety inspection before leasing a residential unit, and the specifics vary from one jurisdiction to the next. On top of local licensing, federal law imposes obligations that follow every landlord in the country: fair housing rules, lead-paint disclosure for pre-1978 homes, and income tax on every dollar of rent collected.
Local Rental Licenses and Permits
A rental license is how a local government confirms that a property meets minimum habitability and safety standards before tenants move in. Not every jurisdiction requires one, but a large and growing number of cities and counties do. The usual process is an application to the municipal housing or code enforcement office, a fee, and a property inspection. Annual fees run roughly from $25 to several hundred dollars depending on where you are and how many units you rent.
Some jurisdictions separate a general business license from a property-specific rental permit. The business license registers you as someone conducting a commercial activity by collecting rent. The rental permit, sometimes called a certificate of compliance, confirms the physical property meets local codes. You may need both. In some cities, landlords who rent four or more units also have to obtain a business tax certificate on top of the rental permit.
The fastest way to find out what applies to you is to call your city or county clerk’s office or search the municipality’s website for “rental license” or “rental registration.” If the property sits inside an incorporated city, the city’s rules apply. If it’s in an unincorporated area, check with the county. Skipping this step is the single most common mistake new landlords make, and the penalties for renting without a required license can be steep.
Zoning and Occupancy Limits
Before you list the property, confirm that local zoning allows it to be rented. Zoning ordinances divide land into categories (residential, commercial, agricultural), and not all residential zones automatically permit rentals. Some districts restrict short-term rentals or cap the number of unrelated people who can live together in a single dwelling. A zoning violation can lead to fines and an order to stop renting.
Occupancy limits work alongside zoning. Local building codes typically set a maximum number of occupants based on bedroom count and livable square footage, both to prevent overcrowding and to ensure safe egress in an emergency. As the landlord, you are responsible for knowing those caps. Advertising a two-bedroom unit for six tenants invites code enforcement action.
Accessory Dwelling Units
Renting out a detached garage apartment, basement suite, or other secondary unit on your lot means dealing with accessory dwelling unit (ADU) rules. Many jurisdictions now allow ADUs in single-family zones, but they usually require a separate permit and have to meet specific standards: minimum and maximum square footage, off-street parking, independent kitchen and bathroom facilities, and design compatibility with the main house. A common requirement is that the property owner lives on the lot, in either the main house or the ADU, for the rental to continue.
Safety Inspections
Where a rental license is required, the inspection is usually the gatekeeper. A municipal code enforcement officer walks through the property checking compliance with local building and fire codes. Expect them to check structural condition, electrical wiring, plumbing, heating, smoke detectors, carbon monoxide alarms, window locks, handrails, and working appliances.
The items that most often hold up a license are small and fixable: missing or expired smoke detectors, no carbon monoxide alarm on a floor with a gas appliance, broken window locks, exposed wiring, a water heater without proper venting, and loose or missing handrails. Fixing these before the inspection saves time and re-inspection fees. If the property fails, you’ll get a list of violations and a deadline to correct them. Renting the unit before passing re-inspection is typically illegal and can result in fines or license revocation. Some jurisdictions require periodic re-inspections every few years, not just at initial licensing.
Federal Fair Housing Rules
Federal law restricts how you advertise, screen, and manage tenants, and these rules apply to nearly every landlord in the country regardless of whether your city requires a license. The Fair Housing Act prohibits discrimination based on race, color, religion, sex, national origin, familial status, and disability in the sale or rental of housing.1Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices
In practice, that means you cannot turn away applicants because they have children, refuse to rent to someone based on their religion, or write a listing that says “perfect for young professionals” (which implies families with children aren’t welcome). Advertising language, application criteria, lease terms, and property rules all have to be neutral. Even well-intentioned preferences, like wanting “quiet tenants” when what you really mean is “no kids,” can trigger a complaint.
Disability protections go further. You have to allow tenants to make reasonable modifications to the unit at their own expense, and you have to provide reasonable accommodations in rules and policies. A no-pets policy, for example, does not apply to service animals or emotional support animals with proper documentation.
Violations expose landlords to actual damages, punitive damages, and the other party’s attorney’s fees.2Office of the Law Revision Counsel. 42 US Code 3613 – Enforcement by Private Persons There is no cap on punitive damages in private lawsuits, and HUD can pursue administrative enforcement with its own penalty structure. Many states and cities add protected classes beyond the federal list, such as sexual orientation, gender identity, source of income, or immigration status, so check your local human rights ordinance as well.
Lead-Based Paint Disclosures
If your rental property was built before 1978, federal law requires you to disclose what you know about lead-based paint before a tenant signs the lease. This is not optional, and it applies in every state.3Office of the Law Revision Counsel. 42 US Code 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property
Before the tenant is obligated under the lease, you have to provide the EPA’s “Protect Your Family From Lead in Your Home” pamphlet, a written disclosure of any known lead paint or lead hazards in the property, and copies of any available inspection reports or risk assessments.4eCFR. Subpart A – Disclosure of Known Lead-Based Paint and/or Lead-Based Paint Hazards Upon Sale or Lease of Residential Property The lease itself has to include a Lead Warning Statement, and both you and the tenant have to sign it. Keep a copy of the signed disclosures for at least three years.
Civil penalties reach $21,699 per violation under the most recently published EPA inflation adjustment, and a tenant who suffers harm can sue for triple damages plus attorney’s fees.5U.S. Environmental Protection Agency. Amendments to the EPA Civil Penalty Policies to Account for Inflation Knowingly ignoring the requirement can also trigger criminal sanctions.
Taxes on Rental Income
Every dollar of rent you collect is taxable income, reported on Schedule E of your tax return. Rental income is broader than monthly rent: advance payments, lease cancellation fees, and expenses a tenant pays on your behalf all count.6Internal Revenue Service. Topic No. 414, Rental Income and Expenses
The tax code lets you deduct ordinary and necessary expenses of running the rental. Common deductions include mortgage interest, property taxes, insurance premiums, repairs, maintenance, property management fees, and legal or accounting costs related to the rental.7Internal Revenue Service. Publication 527 (2025), Residential Rental Property Improvements that add value or extend the property’s useful life, as opposed to simple maintenance, must be capitalized and depreciated rather than deducted immediately. Depreciation itself is one of the biggest tax benefits of owning rental real estate: the IRS lets you recover the cost of a residential rental building (not the land) over 27.5 years using the straight-line method.8Office of the Law Revision Counsel. 26 US Code 168 – Accelerated Cost Recovery System
Here’s where a lot of new landlords get surprised. The IRS treats rental real estate as a passive activity, so if your rental expenses exceed your rental income, you generally cannot use the loss to offset wages or other non-rental income. There’s a limited exception: if you actively participate in managing the property, you can deduct up to $25,000 in rental losses against other income.9Office of the Law Revision Counsel. 26 US Code 469 – Passive Activity Losses and Credits Limited That $25,000 allowance phases out once adjusted gross income exceeds $100,000 and disappears at $150,000. Losses you can’t use carry forward to future years.
Keep records that back up every number on your return: receipts, bank statements, canceled checks, contractor invoices, and mileage logs for trips to the property.10Internal Revenue Service. Tips on Rental Real Estate Income, Deductions and Recordkeeping Hold onto everything for at least three years after filing, and longer where depreciation is involved, because the IRS can look back at your depreciation basis for the life of the asset. Failing to report rental income or inflating deductions can trigger accuracy-related penalties and interest, and in extreme cases criminal prosecution. Willful tax evasion is a felony punishable by fines up to $100,000 and up to five years in prison.11Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax
Some jurisdictions also impose local occupancy taxes, particularly on short-term rentals. These are usually a percentage of the nightly rate and have to be remitted to the local tax authority, sometimes monthly. Platforms like Airbnb collect and remit these taxes in some areas but not all; the ultimate responsibility sits with the property owner.
Security Deposits
Nearly every state regulates how much you can charge for a security deposit, how you have to store it, and when you have to return it after a tenant moves out. Caps range from one month’s rent to three months’ rent in states that set a maximum, and some states impose no statutory cap at all. Rules on separate accounts, interest, and return deadlines vary significantly.
Getting deposit procedures wrong is one of the easiest ways to land in small claims court. In many states, a landlord who misses the statutory return deadline or fails to provide an itemized list of deductions can be liable for double or triple the deposit amount. Check your state’s landlord-tenant statute before you collect a single dollar.
What Happens if You Skip the License
Penalties for operating an unlicensed rental vary by jurisdiction but can include daily fines, back-payment of licensing fees, and orders to vacate tenants until the property is brought into compliance. Repeated violations can result in permanent revocation of your ability to obtain a rental license for that property.
Beyond fines, an unlicensed or code-violating property opens you up to tenant remedies. Most states recognize an implied warranty of habitability, meaning your tenant’s obligation to pay rent depends on your keeping the property in livable condition. If you fail to maintain the property, or lack the required license or certificate of compliance, tenants in many jurisdictions can withhold rent, make repairs and deduct the cost, or terminate the lease without penalty.
Unsafe conditions caused by neglected maintenance or code violations can also generate personal injury claims. A tenant or visitor injured by faulty wiring, a broken staircase, or a missing smoke detector has grounds for a lawsuit, and your insurance carrier may deny coverage if you were renting without a required license. Uninsured liability from an unlicensed rental is the financial worst case, and it’s more common than most new landlords realize.
Possible Exemptions
Not every rental arrangement triggers the same licensing requirements. Owner-occupied properties, where you live in one unit and rent another in a duplex for example, are exempt from certain local licensing rules in many jurisdictions. Safety and occupancy standards usually still apply, but the permitting process may be lighter or waived.
Short-term rentals often operate under a separate regulatory framework. Many municipalities require a specific short-term rental permit, cap the number of nights per year a property can be rented, or restrict short-term rentals to certain zoning districts. If you plan to list on a vacation rental platform, look for your city’s short-term rental ordinance specifically; the rules for a 30-day lease and a 3-night stay are usually different.
The Fair Housing Act has a narrow exemption sometimes called the “Mrs. Murphy” exception: if you own a building with four or fewer units and live in one of them, you are exempt from some (but not all) of the Act’s provisions. Even under this exemption, discriminatory advertising is still illegal.1Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices Many state fair housing laws have no such exemption, so the federal carve-out may not help you in practice.
When to Call an Attorney
An experienced real estate attorney is worth the cost when you’re renting for the first time, managing properties in an unfamiliar jurisdiction, or facing a tenant dispute headed toward litigation. An attorney can review your lease for compliance with local and state law, advise on required disclosures, and confirm which licenses and permits apply to your situation. Legal help becomes especially important when a tenant files a fair housing complaint, a code enforcement action threatens your license, or you need to navigate an eviction.
