City Limits vs. Unincorporated County: Which STR Rules Apply to Your Property?

Why Jurisdiction Matters More Than You Think

In the United States, local government authority over property is divided between two types of jurisdictions: incorporated municipalities (cities, towns, villages) and unincorporated county territory. These two types of jurisdictions have entirely separate governments, separate permit offices, separate rules, separate fees, and separate enforcement mechanisms.

For short-term rental hosts, getting this wrong means one of two outcomes: you apply to the wrong office and waste weeks waiting for a permit that doesn't apply to your property, or you get a city permit when you needed a county permit (or vice versa) and face a violation notice when an inspector discovers the discrepancy.

The same street can straddle two different jurisdictions — your mailing address doesn't determine which rules apply.

The Two Jurisdictions Explained

Incorporated Municipalities (Cities, Towns, Boroughs)

An incorporated municipality is a city, town, village, or borough that has been formally chartered by the state and has its own local government — a mayor, city council, city police department, city planning department, and its own set of ordinances. When your property is inside an incorporated municipality's boundaries, that city's rules apply.

For STR purposes, this means the city's planning or zoning department issues permits, the city's code enforcement investigates violations, and city ordinances determine whether, where, and how you can rent short-term. If the city doesn't have an STR program, the absence of regulation at the city level may or may not translate to "no permit required" — sometimes the county program fills the gap, and sometimes nothing does.

Unincorporated County Territory

Unincorporated county territory is the land within a county's geographic boundaries that is not part of any incorporated city or town. In many states — particularly in the South and Mountain West — a significant portion of the population lives in unincorporated county areas. These areas are governed directly by the county government: county commission, county planning, county code enforcement.

For STR purposes, the county's rules apply. If Sevier County, TN has an STRU permit program that covers unincorporated areas, that's the relevant permit for a property sitting two miles outside Gatlinburg's city limits — even if that property has a "Gatlinburg" mailing address and its guests call it a "Gatlinburg cabin."

How to Determine Your Property's Jurisdiction

There are three reliable methods, listed in order of accuracy:

1. Use your county's GIS parcel viewer

   Every county in the U.S. maintains a geographic information system (GIS) database of all parcels. Search for your property address or parcel number. Parcel maps show municipal boundaries — if your parcel is inside a city boundary, you're in that city's jurisdiction. If it's outside all municipal boundaries, you're in unincorporated county territory. This is the most definitive method and takes about 5 minutes.

2. Call the county planning office and ask directly

   Call the county planning or zoning department with your property address. Ask: "Is this property in unincorporated county territory or within a municipality's limits?" They will tell you immediately and can direct you to the right permit office.

3. Check your property tax bill

   Your annual property tax bill lists both county taxes and, if applicable, municipal taxes. If you're paying both county property tax and a city or town property tax, you're inside city limits. If you're only paying county property tax, you're likely in unincorporated territory. This method is less precise because some areas have complicated tax district structures, but it's a useful first check.

Real-World Examples: Where the Line Gets Confusing

Sevier County / Gatlinburg, TN

The Smoky Mountains cabin market is the clearest example of jurisdiction confusion in the STR world. Sevier County contains the incorporated cities of Gatlinburg, Pigeon Forge, Sevierville, and Pittman Center, plus thousands of square miles of unincorporated territory. Many vacation cabins with Gatlinburg or Pigeon Forge mailing addresses are physically located outside city limits in unincorporated county territory.

Result: a host who calls Gatlinburg's permit office to apply may be told they need to contact Sevier County instead. A host who never calls either may unknowingly operate without any permit because they assumed their city-sounding address meant city-permit territory.

The practical fix: look up your parcel in the Sevier County GIS. If your parcel is outside all city boundary lines, you need the Sevier County STRU permit. If it's inside Gatlinburg, you need the Gatlinburg TR Permit.

South Walton / Walton County, FL

The 30A corridor — including WaterColor, Seaside, Rosemary Beach, Alys Beach, and Grayton Beach — consists almost entirely of unincorporated Walton County. Most of these are census-designated places or private community developments, not incorporated municipalities. Properties in this area fall under Walton County jurisdiction, not any city government, and need the Walton County vacation rental registration plus the Florida DBPR state license.

Exception: a few small incorporated municipalities exist along the 30A corridor. Properties inside these municipality boundaries have their own regulations. Verify your specific parcel.

Nashville Metro / Davidson County, TN

Nashville is unusual because Nashville and Davidson County have a consolidated city-county government. The Nashville Metropolitan Government governs the entire county — there's no separate unincorporated county government. All STR permits in Davidson County go through Metro Codes, and the relevant ordinance applies countywide with zoning-based distinctions.

Austin / Travis County, TX

Austin proper has extremely restrictive STR rules, particularly for non-owner-occupied properties. Many Travis County properties are actually outside Austin's city limits in the unincorporated county, where rules are different (and often more permissive). A property in the same zip code as an Austin address might be outside city limits and governed by the more lenient county framework. The Travis County GIS map makes this easy to check.

When Your Property Straddles a Boundary

In rare cases, a property's parcel may actually sit on or near a municipal boundary. If your parcel viewer shows your property at or near a city limit line, call both the city planning office and the county planning office to confirm which jurisdiction applies. The parcel's primary point — typically the address point or the centroid — usually determines jurisdiction, but edge cases exist and it's worth a phone call to confirm.

What Changes When You Cross the Line

Does Your Property Need Both a City and a County Permit?

Generally, no. For most STR regulatory purposes, you need only one permit — from whichever jurisdiction governs your property. If you're inside city limits, get the city permit. If you're in unincorporated county territory, get the county permit.

There are some exceptions:

• Florida: Requires both a statewide DBPR license (state-level) AND a local county or municipal registration. This is a unique two-layer system.
• Business license: Some jurisdictions require a business license from the city even for properties subject to county STR regulation, and vice versa. These are separate from the STR permit itself.
• Tax registration: You may need to register with both the county and the city for occupancy tax purposes, even if only one issues your STR permit.
