Does Naples, Utah have zoning, and what does it mean for lots and RVs?

Yes. Naples City divides the land inside city limits into zones, and land uses in each zone are limited by Title 171. The city publishes agricultural, residential-agricultural, residential, commercial, industrial and airport districts5.

District matters. In the RA-1 Residential-Agricultural Zone, a one-family dwelling must have at least 750 square feet of floor area7, permitted residential and agricultural uses need a 20,000 square foot lot8, a house and attached garage or carport may cover no more than 40 percent of the lot9, and structures top out at 34 feet10. Other districts have their own numbers.

We could not confirm Naples City's rules for living in an RV, tiny-home occupancy or temporary camping on private land. Ask the city's building official before parking a camper on a lot.

Do you need a building permit in Naples, and who issues it?

Naples City adopts the most recently adopted edition of the International Residential Code for detached single-family and two-family dwellings on individual lots2. The city's forms page lists a basic building permit, a conditional use permit and a driveway access permit3.

The city's building official handles inspections of used moved-in homes and used manufactured homes, which must meet the current IRC or HUD standards11. We could not confirm the city's full building-permit process, fee schedule or owner-builder rules, so call City Hall at the number below before you plan costs3.

Outside city limits, Uintah County Community Development issues building permits for unincorporated land; see the Uintah County page for those rules.

How do septic permits work in Naples, Utah?

Naples City's code accepts either a sewer or an approved septic system as the sanitation connection for a house, alongside water, gas and electric126. A lot without city sewer therefore needs an approved septic system.

Onsite wastewater systems in Uintah County are permitted and inspected by TriCounty Health Department4. We could not confirm a separate city septic permit, so start with the TriCounty Vernal office13.

Soil is a real question: across Uintah County, about 21.8% of soils rate not limited for a conventional drain field, so many lots need a site evaluation or an engineered system14.

Building a home in Naples, Utah: the steps, in order

  1. Confirm the lot's zoning district and that it is a legally subdivided parcel recorded with the Uintah County Recorder15. Ask City Hall for the zoning map5.
  2. Check the district's minimum lot, house size and height rules8.
  3. Contact TriCounty Health about a septic site evaluation and construction permit if no sewer is available13.
  4. Apply for the basic building permit and, if you need it, a driveway access permit at City Hall3.
  5. Build to the adopted International Residential Code, or use a HUD-labeled manufactured home2.
  6. Connect the required utilities permanently before occupancy12.

What stays with Uintah County, and what to check before you buy in Naples?

Septic permits come from TriCounty Health Department for the whole of Uintah County, city or not4. The county's own building and zoning rules cover unincorporated land only, so a parcel just outside Naples City is governed by the Uintah County page, not the city.

Utah requires a permit for shallow wells16; the city's own well rules are unconfirmed. Federal land makes up about 58.7% of Uintah County17, and the county's effective property tax rate is 0.5%18. The state highway access application is listed on the city's forms page if your driveway meets a state road3.

Watch-outs

  • We could not confirm Naples City's building permit fees, application process or owner-builder rules; call the building official at City Hall3.
  • A manufactured home in Naples City must carry a U.S. Department of Housing and Urban Development-approved insignia2.
  • Zoning numbers such as the 20,000 square foot lot apply to RA-1; other districts differ8.
