STR night caps by city: how many nights per year 17 US cities allow

The short answer: most major US cities do not cap how many nights you can short-term rent per year. Of the 17 cities surveyed here, only 5 impose an annual night limit on unhosted (whole-unit, host-absent) rentals, and 1 more (New York City) bans them outright. The most common cap among cities that have one is 90 nights. The remaining 11 cities impose no annual night limit at all.

The comparison table

Every city below was included in our STR permit fees comparison. "Hosted" means the host is physically present in the unit overnight. "Unhosted" means the guest has the entire unit to themselves.

City Unhosted limit Hosted limit Owner-occupied only? Source

What the data shows

The majority of major US cities do not limit how many nights per year a licensed host can rent. Of the 17 cities surveyed, 11 impose no annual night cap at all. The 5 cities that do cap nights share a common pattern: the limit applies to unhosted (whole-unit) rentals only, and hosted rentals (host present overnight) are uncapped in every city that makes the distinction. New York City goes further and bans unhosted whole-unit rentals outright rather than capping them.

The most common cap is 90 nights per year, used by San Francisco and Washington, DC. Portland sets its cap at 95 days, tied to its 270-day residency requirement (365 minus 270 equals 95). Los Angeles is the outlier among capped cities in applying its 120-day limit to both hosted and unhosted rentals.

New York City is in a category of its own. Rather than capping nights, it prohibits unhosted whole-unit rentals under 30 days entirely. A host must be physically present in the same unit during the stay, with a maximum of two paying guests. This is not a night cap but an outright ban on the most common form of short-term rental.

Two patterns worth noting

Night caps track with owner-occupancy requirements

Every city that imposes a night cap also requires the host to be a primary resident. This is not a coincidence. The cap functions as an enforcement mechanism for the occupancy rule: if you rent out your home more than 90 or 120 nights a year, you are unlikely to be living in it as a primary residence. The cap is less about limiting rental activity and more about keeping the unit in the housing supply as a residence.

Cities without caps use other controls instead

The 11 cities with no night cap are not unregulated. Austin uses density caps by census tract. Nashville restricts non-owner-occupied permits by zoning district. Chicago requires shared housing unit registration. Scottsdale is preempted by Arizona state law from imposing most local restrictions. Seattle caps the number of units a single operator can run at two. The absence of a night cap does not mean the absence of regulation; it means the city chose a different lever.

What this means for an operator

If you operate in one of the 11 no-cap cities, the annual night limit is not the constraint on your business. Your constraints are licensing, zoning, density limits, and platform reporting requirements, depending on the city.

If you operate in one of the 5 capped cities (or New York, where the ban is even more restrictive), the cap is the hard constraint on revenue from any single unit. In San Francisco or Washington, DC, 90 unhosted nights means roughly a quarter of the calendar year is available for whole-unit rental. In Los Angeles, 120 days is roughly a third of the year. An operator running a full-time rental business in these cities needs either multiple units (where allowed), a hosted model, or a property in a different jurisdiction.

San Diego's tier system is worth understanding separately. Tier 1 (20 days) is designed for occasional renters. Tier 2 (home-sharing, 90-day absence limit) is for hosts who travel occasionally. Tiers 3 and 4 are whole-home, year-round licenses with a minimum utilization requirement of 90 days, not a maximum. The constraint in San Diego is which tier you qualify for, not the night count within it.
