What Is STR in Real Estate: Permits, Taxes, and Zoning

A short-term rental is a furnished residential property, usually a house, condo, or apartment, rented to guests for stays of fewer than about 30 consecutive days through platforms like Airbnb or Vrbo or by direct booking. Because these properties sit between traditional housing and commercial lodging, operating one means dealing with local permits, zoning limits, HOA and mortgage restrictions, lodging taxes, federal income tax rules, and fair-housing obligations that don’t apply to a standard long-term lease.

How a Short-Term Rental Is Defined

Local governments draw the line based on how long a guest stays. Some jurisdictions use 28 days, some 30, some 31. Anything shorter than roughly one month typically counts as short-term. Once a property crosses that threshold, it stops being governed only by landlord-tenant law and picks up a separate framework covering safety inspections, tax collection, and commercial licensing.

What separates a short-term rental from a hotel room is that it occupies a residential dwelling and includes living spaces like kitchens and separate bedrooms. Guests treat it as a temporary home. Regulators treat the frequent turnover inside residential neighborhoods as a hybrid use, which is why the permitting rules exist in the first place.

Owner-Occupied vs. Non-Owner-Occupied

Many cities distinguish between rentals where you live on the property and rentals where you don’t, and the difference can determine whether you qualify for a permit at all. An owner-occupied rental is one where you live in the home and rent out a spare bedroom or guest suite. A non-owner-occupied rental is a property you own but don’t live in, such as a second home or a full-time investment listing.

Cities with a primary-residence requirement only issue permits for the home you actually live in for most of the year, which effectively blocks investors from converting multiple properties into vacation rentals. Some cities pair that rule with a cap on nights you can rent while away, for example limiting absent-owner rentals to 90 or 120 nights per year. Verification usually involves a government-issued ID, utility bills, or tax returns, and many jurisdictions require annual renewal with updated documentation.

What You Need to Get a Permit

Before submitting an application, you’ll typically need to assemble:

  • Proof of ownership, or written authorization from your landlord if you’re a tenant.
  • Liability insurance covering short-term rental activity, often with a minimum of $1,000,000 in general liability per occurrence.
  • Floor plans showing sleeping areas, bathrooms, exit paths, and the locations of smoke and carbon monoxide detectors.
  • A local contact person available around the clock to respond to emergencies or neighbor complaints.
  • A written management plan covering noise, parking, trash, and maximum occupancy, sometimes called a “good neighbor policy.”

The insurance piece deserves extra attention. Standard homeowners and dwelling policies generally aren’t designed to cover accidents arising from short-term rentals, and even without an explicit exclusion, insurers may deny claims by classifying the rental as a home-based business.1NAIC. Renting Out Your Home? You Need Insurance Coverage for Home Sharing Rentals Confirm in writing with your insurer that guest stays are covered, or buy a dedicated landlord, commercial, or specialized short-term rental policy before you list.

Applications go through the city’s online portal or the local planning or licensing department, and usually trigger a fire or building code inspection. Fees range from around $50 to several hundred dollars, plus a possible separate inspection fee. Processing takes anywhere from a few weeks to several months. Once approved, you get a permit number that must appear on every listing for the property.

Permits are not permanent. Most jurisdictions renew annually, biennially, or triennially, and renewal typically requires confirming that insurance is still active, safety equipment still works, and lodging taxes have been paid. Letting a permit lapse even briefly can bring fines or force you to restart the process, so set calendar reminders well before expiration.

Zoning, HOA, and Mortgage Limits That Can Block You Outright

A city permit isn’t the only gatekeeper. Three separate layers can shut down a short-term rental even when everything else is in order.

Zoning. Your zoning district decides whether short-term rentals are allowed at all. Many cities restrict them to specific districts or ban them in single-family residential zones. Even where permitted, cities often cap the number of active permits in a neighborhood, block, or radius, and once the cap is hit, new applicants get waitlisted or denied. A few jurisdictions also require minimum distances between rental properties or between a rental and land uses like schools or parks. Violations can bring escalating daily fines, permit revocation, or a court order to stop operating.

HOA rules. Homeowner association bylaws can prohibit short-term rentals even when the city allows them. Check your CC&Rs before you apply for a permit. An HOA violation can mean fines or forced delisting on top of, or independent of, anything the city does.

Mortgage terms. Many residential mortgage contracts restrict or prohibit short-term rental activity, and operating one without your lender’s knowledge can be treated as a breach. In a worst case, the lender can accelerate the loan, making the entire balance due immediately, or start foreclosure. The risk is highest with conventional loans backed by Fannie Mae or Freddie Mac, which have occupancy requirements for primary residences and second homes. If your loan classifies the property as a primary residence, listing it full-time on a booking platform may violate that classification. Talk to your lender or servicer before you list.

Lodging and Sales Taxes

Operating a short-term rental triggers tax obligations a long-term rental doesn’t. The most common is the transient occupancy tax, also called a lodging tax, hotel tax, or bed tax. Rates are a percentage of the nightly rate, typically between about 5% and 15%, sometimes higher. Many states and localities also apply general sales tax on top.

Platforms like Airbnb automatically collect and remit lodging taxes in many jurisdictions but not all, and even where the platform handles collection, you remain ultimately responsible for making sure the right amount reaches the right authority. If the platform covers a state-level tax but not a separate city or county tax, you owe the difference. Late payments commonly bring penalties of around 10% of the unpaid amount plus interest, and repeated noncompliance can cost you the permit.

Federal Income Tax Rules

Rental income is subject to federal income tax, and the rules depend on how many days you rent, what services you provide, and whether the property also serves as your personal home.

The 14-Day Rule

If you rent a home you also use as a residence for fewer than 15 days during the tax year, you don’t have to report any of the rental income to the IRS, and you can’t deduct any rental expenses either.2Office of the Law Revision Counsel. 26 U.S. Code 280A – Disallowance of Certain Expenses in Connection With Business Use of Home, Rental of Vacation Homes, Etc. This is sometimes called the “Masters exemption” because owners near events like golf tournaments can pocket a few weeks of tax-free income. Hit 15 days or more and all rental income for the year becomes reportable.3Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property

Schedule C or Schedule E

Once you’re past 14 days, where you report the income depends on the level of service you give guests. Most owners use Schedule E of Form 1040, which is generally not subject to self-employment tax. If you provide “substantial services” beyond basic property management, such as daily cleaning, meal preparation, concierge services, or guided activities, the IRS may treat the rental as a business belonging on Schedule C. Schedule C income is subject to the 15.3% self-employment tax for Social Security and Medicare.

The dividing line is whether your services resemble a hotel’s. Cleaning between guests, providing linens, and leaving a welcome basket are basic services that keep you on Schedule E. Daily housekeeping, room service, or organized activities push you toward Schedule C.

Deductible Expenses

Whether you file on Schedule C or Schedule E, you can deduct ordinary and necessary expenses tied to the rental, including mortgage interest, property taxes, insurance premiums, management fees, platform commissions, cleaning, repairs, supplies, and depreciation on the property and its furnishings.4Internal Revenue Service. Instructions for Schedule E (Form 1040) If the property doubles as your personal residence, you’ll need to allocate expenses between personal and rental use based on the number of days for each.

Platform Reporting

Booking platforms are required to send you and the IRS a Form 1099-K if your gross payments exceed $20,000 and you have more than 200 transactions in the year.5Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill Below that threshold, no form comes, but the income is still reportable. Keep detailed records of every booking, including dates, amounts, platform fees, and any taxes the platform withheld or remitted on your behalf.

Fair Housing and Accessibility

The Fair Housing Act prohibits housing discrimination based on race, color, national origin, religion, sex (including sexual orientation and gender identity), familial status, and disability. These protections generally apply to short-term rental hosts, meaning you cannot refuse a booking or set different terms based on those characteristics. A limited exemption exists for owner-occupied dwellings with no more than four rental units, sometimes called the “Mrs. Murphy exemption,” but it does not allow discriminatory advertising and does not override broader state or local laws.6Office of the Law Revision Counsel. 42 U.S. Code 3603 – Effective Dates of Certain Prohibitions

On physical accessibility, a rental that operates like a hotel, with a reservation system, housekeeping, and non-specific unit assignments, may be a place of public accommodation under Title III of the Americans with Disabilities Act. If you rent five or fewer rooms and live on the property, the ADA generally doesn’t apply. With six or more reservable rooms, or without an on-site owner, the property may need to meet the same accessibility standards as a hotel. Whether or not the ADA applies, refusing to rent to someone because of a disability, or refusing a reasonable accommodation like allowing a service animal, violates the Fair Housing Act.
