A short-term rental property is a residential home, condo, apartment, accessory dwelling, or private room that you rent to guests for fewer than 30 consecutive days at a time. That one definition sits at the intersection of four separate rule systems: local zoning decides whether you can operate at your address, licensing rules decide what permits and inspections you need, state and local tax codes decide what you collect from guests, and federal tax law decides how you report the income. Your homeowners association can override all of it and ban the activity on your lot regardless of what the city allows. Getting any one piece wrong can mean daily fines, denied insurance claims, or back taxes with interest.
The 30-Day Line and Why It Matters
Across most of the country, a rental of 30 consecutive days or fewer counts as short-term or “transient” lodging. Once a guest stays 31 days or longer, the arrangement generally shifts into traditional landlord-tenant territory, and the occupant picks up much stronger legal protections.
That line changes what the guest actually holds. A short-term guest usually occupies the property under a license to occupy: permission to use the space for a limited purpose, with no legal interest in the property itself. If the guest overstays or breaks house rules, you can revoke that license relatively quickly. A tenant under a lease, by contrast, has a possessory interest that normally requires a formal eviction to end. Misclassify a long-stay guest as a short-term visitor and you can be stuck in a months-long eviction when you assumed you could change the locks.
Format matters too, but less than the duration. Hosts rent out entire single-family homes, condo units, accessory dwelling units like backyard cottages or basement apartments, and private rooms inside a home they still live in. Regulations often split “hosted” stays, where you remain on site, from “unhosted” stays, where the guest has the place alone. Hosted rentals tend to face lighter restrictions because the owner’s presence reduces neighbor friction. Unhosted stays draw tighter scrutiny and sometimes stricter permit terms.
Zoning: Can You Operate at This Address?
Before you list a property, the first legal question is whether local zoning allows short-term rentals where you are. Residential zoning codes frequently restrict or prohibit transient lodging. The reasoning is practical: constant guest turnover in a quiet residential neighborhood starts to look like a commercial hotel, and commercial uses carry different safety, parking, and infrastructure expectations than a family home.
Treatment varies widely. Some cities ban short-term rentals in all residential zones. Others allow them only in certain overlay districts or mixed-use areas. A growing number permit them broadly but attach conditions. If your property sits in a zone where short-term rentals are prohibited, operating one can trigger cease-and-desist orders, daily fines, and forced delisting from booking platforms.
Day Caps and Primary Residence Rules
Two of the most common tools cities use to limit the activity are annual day caps and primary residence requirements. A day cap restricts how many nights per calendar year you can rent on a short-term basis, with limits commonly set around 90 to 120 days. Once you hit it, you either stop renting or face escalating penalties.
A primary residence requirement goes further. It limits permits to properties where the owner actually lives for the majority of the year, which effectively prevents investors from buying homes to run as full-time vacation rentals. Several major cities enforce some version of this rule. If your rental is a second home or an investment property rather than your primary residence, check local rules carefully before assuming you qualify.
Non-Conforming Use Protections
If you were legally operating a short-term rental before your city changed its rules, you may qualify for non-conforming use or grandfathered status, letting the existing rental continue despite the new restrictions. You’ll need to prove the property was actively used as a short-term rental before the cutoff date. Booking records, tax filings, and prior permits all serve as evidence. These protections typically don’t transfer to a new owner, and they can expire if you stop renting for an extended period.
Permits, Inspections, and Operating Legally
Nearly every jurisdiction that allows short-term rentals requires you to register the property and obtain a permit before the first guest checks in. The typical process involves applying through your local planning or code enforcement department, providing proof of ownership or primary residence, and designating a local contact who can respond to emergencies or neighbor complaints within a set time frame.
Application fees generally run from around $50 to over $500, depending on the jurisdiction. Permits usually expire annually and require renewal, often with a re-inspection. Letting a permit lapse doesn’t just mean you’re unlicensed. In many places, an expired permit is treated as if you never had one, and you’ll have to restart the full application rather than paying a renewal fee.
Most permit applications trigger a safety inspection. Inspectors typically verify working smoke detectors in every sleeping area, carbon monoxide alarms near fuel-burning appliances, unobstructed emergency exit routes, and proper handrails. Many states specifically require carbon monoxide detectors in transient lodging by statute, including in the hotel and motel category that short-term rentals often get classified alongside.1National Conference of State Legislatures. Carbon Monoxide Detector Installation Statutes Some jurisdictions also require fire extinguishers on every floor and posted evacuation maps in guest areas.
Operating without a valid permit exposes you to fines that often run from $100 to $1,000 or more per day of violation, with misdemeanor charges possible for repeat offenders in some places. The insurance consequences are worse. If a guest is injured at an unlicensed property, both your insurer and your city have grounds to deny you any help.
HOA Rules Can Override the City
Even if your city allows short-term rentals and you hold a valid permit, your homeowners association can still shut you down. HOA covenants, conditions, and restrictions are private contractual obligations that run with the property, and they operate independently of municipal zoning. Many HOAs have amended their CC&Rs to explicitly ban or restrict short-term rentals, particularly in condo buildings where turnover affects shared hallways, elevators, and parking.
Enforceability depends on how the original covenants were drafted. If the original CC&Rs already restricted rentals or reserved broad amendment authority, a later ban on short-term leasing typically holds up. Where the original covenants placed no restrictions on renting, some courts have struck down retroactive bans as unreasonable restraints on property rights. A North Carolina appellate court, for example, refused to enforce an HOA amendment banning leases under 90 days because the original covenants “did not prohibit, limit, or regulate the rental of residential lots.” Read your CC&Rs before you list, not after the HOA board sends a cease-and-desist letter.
Insurance Gaps You Need to Close
Standard homeowners insurance is not built to cover short-term rental activity, and this is where a lot of hosts get blindsided. Most homeowners policies exclude or limit coverage for business activity in the home, and renting to paying guests qualifies as a business once you list the property with any regularity.2National Association of Insurance Commissioners. Renting Out Your Home? You Need Insurance Coverage for Home-Sharing Rentals If a paying guest slips on your stairs, the homeowners policy that would normally cover an injured visitor can deny the claim entirely because the person was a commercial guest.
The fix is a commercial general liability policy or a specialized short-term rental insurance product. These are built for transient occupancy and typically cover guest injuries, property damage caused by guests, and lost income if the property becomes uninhabitable. Coverage limits commonly start at $500,000 to $1,000,000 per occurrence. Some booking platforms offer host protection programs, but these are not a substitute for your own policy. Platform coverage often has gaps, exclusions, and slow claims processes that leave you exposed during the weeks it takes to resolve a dispute.
Call your homeowners carrier before your first booking. Some insurers offer short-term rental endorsements that add coverage to your existing policy at a lower cost than a standalone commercial policy. Others will cancel your homeowners policy entirely if they discover undisclosed rental activity, leaving you uninsured for everything, not just the rental.
Lodging and Occupancy Taxes
Short-term rental hosts are responsible for collecting a lodging tax from guests in most jurisdictions. The tax goes by different names: transient occupancy tax, hotel tax, bed tax, or room tax. The mechanics are the same everywhere. You add a percentage to the nightly rate, collect it from the guest, and remit it to the taxing authority on a schedule. State lodging tax rates alone range from under 2% to nearly 16%, and local governments often stack additional taxes on top, pushing combined rates well above 15% in some cities.3National Conference of State Legislatures. State Taxation of Short-Term Rentals
More than 30 states now require booking platforms like Airbnb and Vrbo to collect and remit lodging taxes automatically on behalf of hosts. If your platform handles tax collection in your jurisdiction, the tax gets added at checkout and sent directly to the taxing authority. Platform collection doesn’t necessarily cover every layer, though. Some cities impose additional assessments that the platform doesn’t collect, leaving you responsible for filing and paying the difference yourself. You’re also typically still required to file periodic tax returns with your local tax authority even when the platform handles payment, so keep records of every booking. Unpaid lodging taxes generate penalties and interest fast, and chronic non-compliance can result in permit revocation.
Federal Income Tax Rules
Beyond local lodging taxes, rental income creates federal tax obligations that depend on how many days you rent, how much time you spend on the property yourself, and what services you provide to guests.
The 14-Day Rule
If you rent out your primary home for fewer than 15 days during the tax year and also use it personally, the rental income is completely tax-free. You don’t report it on your return, and you can’t deduct rental expenses against it. Your normal deductions for mortgage interest and property taxes still apply as though no rental occurred.4Office of the Law Revision Counsel. 26 U.S. Code 280A – Disallowance of Certain Expenses in Connection With Business Use of Home If your rental activity stays under 15 days, you pocket the money and owe nothing on it.5Internal Revenue Service. Publication 527 (2025), Residential Rental Property
Cross that threshold and rent for 15 days or more, and all your rental income becomes taxable and must be reported. You can then deduct expenses, but only the portion allocable to the rental use of the property.
Passive Versus Active Income
Rental income is generally classified as passive, which means losses from the rental can only offset other passive income. Short-term rentals often escape that classification. If the average guest stay at your property is seven days or fewer, the IRS does not treat the activity as a rental activity at all.6Internal Revenue Service. Publication 925 (2025), Passive Activity and At-Risk Rules Instead, it’s evaluated as a trade or business. If you materially participate by handling bookings, coordinating cleanings, managing guest communication, and similar tasks, the income is active rather than passive. Active classification lets you deduct losses against your other income, which is a significant tax advantage.
A second exception applies when the average stay is 30 days or fewer and you provide significant personal services alongside the rental, such as daily cleaning, linen changes, or concierge-style assistance. Providing only heat, Wi-Fi, and trash pickup doesn’t count.6Internal Revenue Service. Publication 925 (2025), Passive Activity and At-Risk Rules
Schedule E Versus Schedule C
Most rental income gets reported on Schedule E. If you provide substantial services to guests beyond handing them keys to a furnished space, the IRS treats the activity as a business rather than a rental, and you report on Schedule C instead.5Internal Revenue Service. Publication 527 (2025), Residential Rental Property The practical difference is significant. Schedule C income is subject to self-employment tax (an additional 15.3% on net earnings), while Schedule E income is not. Substantial services means things like regular maid service, daily linen changes, or providing meals. Furnishing a clean unit with towels at check-in and offering a lockbox code does not cross that line.
The Qualified Business Income Deduction
Short-term rental owners who operate as sole proprietors or through pass-through entities like S corporations, partnerships, or LLCs may qualify for the Section 199A deduction, which allows you to deduct up to 20% of your qualified business income from the rental.7Internal Revenue Service. Qualified Business Income Deduction The deduction was originally set to expire after 2025 but was made permanent by legislation signed in July 2025. To qualify, your rental activity needs to rise to the level of a trade or business. The IRS offers a safe harbor specifically for rental real estate enterprises that meet certain requirements, including maintaining separate books, performing at least 250 hours of rental services per year, and keeping contemporaneous records.
What You Can Deduct
Once your rental activity is taxable (meaning you exceed the 14-day threshold), you can deduct a range of operating expenses against your rental income. The common ones:
- Depreciation on the building (not the land) over 27.5 years for residential property. Furnishings, appliances, and other personal property inside the rental typically depreciate over five to seven years.
- Mortgage interest on the loan used to buy or improve the rental property, including private mortgage insurance premiums where applicable.
- Property taxes attributable to the rental use, separate from the $10,000 SALT cap that applies to personal deductions.
- Repairs and maintenance that keep the property in its current condition, such as fixing a broken lock, repairing plumbing, or repainting walls, fully deductible in the year you pay for them.
- Cleaning and supplies, including turnover cleaning between guests, restocking toiletries, and replacing linens.
- Insurance premiums on your short-term rental or commercial liability policy.
- Platform fees and service charges from Airbnb, Vrbo, and similar sites, if they’re included in your reported rental income.
- Professional services, including property management fees, legal costs for drafting rental agreements, and accounting fees for tax preparation.
Capital improvements that add value or extend the property’s useful life, like a kitchen remodel or a new HVAC system, can’t be deducted all at once. These must be capitalized and depreciated over their useful life. The distinction between a deductible repair and a capitalizable improvement trips up many hosts, so keep records that clearly describe what work was done and why. A plumber fixing a leaky pipe is a repair. Replacing all the plumbing in the house is an improvement.
If you use the property personally for part of the year and rent it the rest, you must allocate expenses between personal and rental use based on the number of days in each category. Only the rental-use portion is deductible.5Internal Revenue Service. Publication 527 (2025), Residential Rental Property
