Inspection process

  1. 1

    Foundation Inspection

    Made after trenches are excavated, forms erected, and required reinforcement steel is in place. Frost depth is checked for all exterior footings (monolithic slab/footings also need to reach frost depth). Also checks building location relative to setbacks while footers/foundation are formed but not poured.

  2. 2

    4-Way Inspection

    Framing (before building wrap or roofing underlayment), rough electrical, rough plumbing, rough mechanical — made after roof, framing, fire-blocking, and bracing are in place, and pipe chimneys/vents are complete, before any work is concealed.

  3. 3

    Septic System Inspection

    Final on-site inspection of house sewer, septic tank, and absorption field lines after completion but before the system is covered — usually performed by the San Juan County Health District Sanitarian, sometimes the Building Official. A separate Septic Permit is required.

  4. 4

    Final Inspection

    Made after finished grade and building is complete and ready for occupancy, but before occupied — includes porches, steps, decks, railings, sidewalks, and driveways. The completed building should not be occupied until a written Certificate of Occupancy is issued.

Tips

  • Every request for inspection must be filed at least 48 hours in advance, by phone (435-587-3221) or email (building@sanjuancountymail.org per the county's Building Permit Checklist; the department's general contact email is permits@sanjuancountyut.gov).
  • San Juan County requires the building lot to be deeded in the applicant's name and recorded with the San Juan County Recorder's Office (or a notarized owner-permission statement) before the county will issue a building permit.
  • If your property is within the Town of Bluff, you must first obtain a Land Use Clearance from the Bluff Planning & Zoning Commission — the LUC is valid for one year, and if a building permit is not acquired within that year, a new LUC is required.
  • Investigation fees equal to the permit fee are charged if construction work begins before a permit is obtained, plus $150/week if the violation continues beyond a 30-day notice, per the county's official Building Department webpage.
  • Owner-builders acting as their own contractor on a personal, non-commercial single-family residence are permitted under the Utah Construction Trades Licensing Act, but unlicensed-contractor violations can be a class A misdemeanor plus an administrative fine up to $2,000/day; all commercial project work must be performed by licensed contractors. Owner-builderContractor
  • Rooftop or ground-mounted solar PV installations require this same Residential Building Permit — San Juan County's Building Department webpage (sanjuancountyut.gov/building), live-checked 2026-07-19, publishes no distinct solar-specific fee tier or permit type, so solar installs are billed under the same combined Plan Review & Building Permit formula (1.75× square footage); confirm with the department at (435) 587-3829 how valuation is calculated for a non-structure PV system.
  • EV charger / EVSE installation would fall under this same Residential Building Permit — San Juan County's Building Department webpage (re-checked 2026-07-20) publishes no distinct EV/EVSE fee tier or permit type (consistent with its treatment of solar, above); a standalone EV charging circuit would be expected to be billed under the county's $65.00-per-inspection Inspection Fee rather than the combined Plan Review & Building Permit valuation formula used for new structures.

Blanding operates its own independent building department (its own Building Official, Taylor Francom, using the CityInspect online permitting platform) — Blanding is NOT covered by this county file. The Town of Bluff, however, requires applicants to first obtain a Land Use Clearance from the Bluff Planning & Zoning Commission, after which San Juan County's Planning & Building Department issues the actual building permit — so Bluff IS effectively covered by this county file for the building-permit-issuance step, even though Bluff retains its own local land-use/zoning sign-off.
