STR primary residence rules by city: which of 17 cities allow investment STRs

The short answer: most major US cities restrict short-term rentals to properties where the host actually lives. Of 17 cities surveyed, 8 allow only primary-residence STRs (no investment properties). Another 8 allow non-owner-occupied permits, but every one of those 8 attaches caps, zone restrictions, or both. Only Scottsdale, protected by Arizona's state preemption law, has no owner-occupancy requirement at all.

Verify before you act. This table was checked in September 2026 against each city's published page. Primary residence definitions, zone maps, and permit caps change. Confirm the current rule with your city's licensing office before buying or listing a property.

The comparison table

"Primary residence" means different things in different cities: Denver says it is where your driver's license is registered. Portland says you must occupy the unit at least 270 nights per year. San Francisco says 275 nights. The definition matters because it determines whether a second home, a pied-a-terre, or a property managed by someone other than the owner qualifies.

City Rule Non-owner-occupied? How it works Source
Austin, TX Both types Yes (Type 2) Type 1: owner-occupied. Type 2: non-owner-occupied whole-dwelling, allowed in most zones but must be 1,000+ ft from another Type 2 in residential areas. Restored by Anding v. City of Austin (2023). austintexas.gov
Boston, MA Primary only No STRs restricted to owner-occupied condos, single-family, and 2-3 family buildings. Owner must occupy the property 9+ months per year. No true non-owner-occupied category exists. boston.gov
Charleston, SC Primary only Host must be present No Owner-occupied only, verified via property tax records. At least one full-time resident must be present each night of the stay. Non-owner-occupied STRs banned outright. charleston-sc.gov
Chicago, IL Both types 5+ unit buildings only Limited Primary residence = 245+ days/year. Single-family and 2-4 unit buildings: owner's unit only. Buildings with 5+ units: up to 25% of units (or 6, whichever is smaller) may register without owner-occupancy. True non-owner-occupied only possible in larger buildings. chicago.gov
Colorado Springs, CO Both types Zone-gated Limited Owner-occupied: principal residence, on deed, 185+ days/year. Non-owner-occupied applications filed after December 2019 are prohibited in single-family zoning districts. Pre-2019 non-owner-occupied permits may be grandfathered. coloradosprings.gov

Tier 3: whole-home, non-owner-occupied, capped at 1% of housing units (~808 licenses remaining). Tier 4: Mission Beach whole-home, capped at 30% of dwellings (waitlist only, 1,099 issued). Two-night minimum stay all tiers. sandiego.gov
San Francisco, CA Primary only No Permanent resident = 275+ nights/year in the unit. Absentee owners ineligible. Un-hosted (owner-absent) stays capped at 90 nights/year even for qualifying residents. sfplanning.org

Owner-occupied exempt from cap. All wards have hit the cap (waitlist only for non-owner-occupied). Streetcar District: owner-occupied only. savannahga.gov
Scottsdale, AZ No restriction Yes Arizona state law (A.R.S. 9-500.39) preempts cities from restricting STRs based on owner-occupancy. Scottsdale's license applies uniformly regardless of whether the owner lives in the property. scottsdaleaz.gov
Seattle, WA Both types 2-unit cap Yes (1 secondary unit) Operators limited to 2 total STR units. At least one must be their primary residence (6+ months/year). The second, non-primary unit must also register under the Rental Registration and Inspection Ordinance. seattle.gov
Washington, DC Primary only No Property must be owned by a natural person and be their primary residence (Homestead Tax Deduction eligibility as proof). Two endorsements: Short-Term Rental (host present, no night cap) and Vacation Rental (host absent, 90-night cap). Both require primary-residence status. dlcp.dc.gov

What the data shows

The split is nearly even: 8 cities restrict STRs to primary residences, 8 allow non-owner-occupied permits with restrictions, and 1 has no owner-occupancy requirement. But "allowed with restrictions" does a lot of work. In practice, the non-owner-occupied path in most of those 8 cities is narrow: a specific zone, a hard cap, a waitlist, or all three.

San Diego has the most structured system: four explicit tiers with different rules for each. Savannah has the most restrictive "allowed" category: the 20% ward cap is already full across all eligible wards, so new non-owner-occupied permits go on a waitlist. Nashville and New Orleans gate non-owner-occupied permits by zone (commercial or mixed-use areas only), while Chicago gates by building size (5+ units only).

Three patterns worth noting

"Primary residence" has no standard definition

The minimum occupancy to qualify as a primary resident ranges from 183 days (New York City) to 275 nights (San Francisco). Denver does not specify a day count but requires the property to match the licensee's driver's license and vehicle registration. Portland requires 270 days. Boston says 9 months. Charleston checks property tax records. The same person could qualify as a primary resident in one city and not in another, depending on which city's calendar they are measured against.

Two cities require the host to be physically present during the stay

Charleston and New York City go beyond primary residence and require the host to be in the property while guests are there. This is the strictest form of owner-occupancy: it eliminates not just investment properties but also primary-residence owners who want to rent the whole unit while traveling. Portland comes close with its 95-day absence cap, but Portland does not require the owner to be present during the actual stay.

State preemption is the exception, not the rule

Scottsdale is the only city in this survey with no owner-occupancy requirement, and that is not because Scottsdale chose not to restrict. Arizona's state legislature passed A.R.S. 9-500.39, which preempts cities from prohibiting or restricting STRs based on the owner's occupancy status. Scottsdale's hands are tied by state law. No other state represented in this survey has the same blanket preemption, though several states have varying degrees of preemption legislation that limits (without eliminating) local authority.

What this means for an operator

If you are buying an investment property specifically to operate as a short-term rental, the primary-residence question is the first filter. In 8 of these 17 cities, a non-owner-occupied STR is simply not legal. In most of the other 8, it is legal only in specific zones or subject to hard caps that may already be full.

If you already own a primary residence and want to rent it while you travel, the question shifts to how the city defines "primary" and whether it restricts how many nights you can be absent. San Francisco caps un-hosted nights at 90. Portland caps absences at 95 days. Los Angeles caps total rental nights at 120. These are not the same number, and they are not measured the same way.

If you operate through a property management company, the owner-occupancy requirement usually still applies to you, the owner, not to the manager. Having a local property manager does not substitute for primary-residence status in any of these cities.
