What Is a Short-Term Rental? Definition, License and Permit Guide
What is a short-term rental? A short-term rental is a furnished home, apartment or room rented to guests for short stays, most often defined in local law as stays of fewer than 30 consecutive nights. The exact definition depends on who is asking: a city ordinance, a state tax agency and the IRS can each draw the line in a different place.
This guide explains the common definitions, how short-term rentals differ from mid-term and long-term rentals, when a short-term rental license or permit is required, and how ChargeAutomation helps operators run short stays once they are licensed.
Key Takeaways
A short-term rental is a furnished property rented for short stays, and many US cities define it as a stay of fewer than 30 consecutive nights.
New York City's Local Law 18 applies to stays of fewer than 30 days, while stays of 30 days or more fall outside its short-term rental registration rules.
For federal tax purposes, the IRS passive activity rules treat property with an average customer stay of seven days or less differently from a rental activity.
Many cities require a short-term rental license, permit or registration number before listing, and rules on night caps and primary residences vary widely.
ChargeAutomation is not part of any licensing process, but it helps licensed operators with online check-in, ID verification, payments and chargeback protection.
What Is Considered a Short-Term Rental?
A short-term rental is a furnished dwelling rented to guests for a short stay, usually booked through platforms such as Airbnb, Vrbo or Booking.com or through a direct booking website. In most US city codes, the short-term rental definition is a stay of fewer than 30 consecutive nights, which separates it from traditional leases.
New York City is a clear example: its Local Law 18 registration rules apply to stays of fewer than 30 days, and stays of 30 days or more fall outside them. Other cities use the same 30-night line, while some use shorter thresholds or count nights per year rather than per stay.
Tax law can use a different line. For federal passive activity rules, the IRS looks at the average period of customer use, and property with an average stay of seven days or less is not treated as a rental activity. That is a tax classification, not a zoning definition, so a property can be a short-term rental under city law for one reason and under tax rules for another.
Platforms draw their own lines as well. Airbnb, for example, treats reservations of 28 or more consecutive nights as monthly stays with separate long-term cancellation policies. Stays from about one month to several months are often called mid-term rentals, and they usually sit outside short-term rental ordinances that use a 30-night threshold.
What is considered a short-term rental depends on these factors:
Length of each stay, often under 30 nights
Whether the unit is furnished
Whether the host lives on site
Local zoning and ordinance definitions
State lodging tax rules
Federal tax rules based on average stay
Do You Need a Short-Term Rental License or Permit?
Many US cities and counties require a short-term rental license, permit or registration before a property can be listed. The process usually involves an application, a fee, proof of ownership or the owner’s consent, a safety inspection in some places and a registration number that must appear on every listing.
Requirements vary widely. Some cities issue a short-term rental permit to any compliant property, some limit permits to primary residences, some cap the number of permits in certain neighborhoods and some ban non-owner-occupied short-term rentals altogether. States may also require a sales or lodging tax license separate from the local permit.
Because rules change often, check the city or county website for your exact address before buying, leasing or listing a property. Unregistered listings can face fines, and platforms in some cities must verify registration before accepting bookings, so an STR license is often the first operational step, not the last.
A short-term rental license or permit application often asks for:
Application form and fee
Proof of ownership or owner consent
Floor plan and maximum occupancy
Safety inspection or self-certification
Proof of insurance
State or local tax account number
Registration number to show on listings
How ChargeAutomation Helps Licensed Short-Term Rental Operators
Applying for a short-term rental license or permit is handled directly with the city, county or state, and ChargeAutomation is not part of that process. Once a property is licensed and taking bookings, ChargeAutomation helps operators run short stays smoothly and protect revenue.
ChargeAutomation sends every guest one link for online check-in, where they confirm details, sign the rental agreement and receive access instructions. Properties can achieve up to 93% online check-in completion, and access codes can appear only after the guest completes check-in. For direct bookings, ChargeAutomation verifies identity with a government ID and a live selfie.
Payments run automatically on the schedule you set, with security deposit holds instead of charges and 3D Secure authentication on eligible payments, which usually shifts fraud dispute liability to the card issuer. ChargeAutomation integrates with 50+ PMS platforms, including Guesty, Hostaway and Lodgify. Launch your online check-in at chargeautomation.com.
