New homes, additions and structural or major system changes generally require permits. Confirm the city or county building authority for the property before work starts, including zoning and utility approvals. Unpermitted work can lead to enforcement, corrective work and occupancy delays; consequences depend on the project and jurisdiction. Request a current review estimate from that authority rather than relying on a statewide number.

TL;DR:

  • Most Utah jurisdictions require permits for new homes, additions, accessory structures, pools, and any work on vital systems to ensure code compliance.
  • Permits are applied for online through jurisdiction-specific portals, with delays caused mainly by incomplete or incorrect submissions like non-PDF files or missing documentation.
  • Review timing depends on the jurisdiction, application completeness, project scope and correction cycles; obtain a current local estimate.
  • Inspections are mandatory at multiple stages, including foundation, framing, and system rough-ins, and missing them can delay obtaining the Certificate of Occupancy.
  • Verifying contractor licenses and scheduling inspections early can prevent delays, with owner-builders assuming full responsibility for code compliance.

Which Projects Need a Building Permit in Utah?

New single-family homes require building approval. Additions, basement finishes, accessory buildings and structural or system work may require permits and supporting approvals. Ask the authority serving the property which permit types, exemptions and thresholds apply; a different county’s checklist is not a statewide rule.

Here’s where homeowners get tripped up: local building departments have discretion to require a permit for projects that seem borderline, like a large shed, a retaining wall past a certain height, or a re-roof that changes structural framing. Never assume a project is too small to count.

  • New home construction, room additions, and basement or garage finishes
  • Accessory structures (sheds, casitas, detached garages) above the local size threshold
  • Swimming pools, spas, and hot tubs
  • Gas, electrical, mechanical or plumbing work subject to local permit requirements and applicable exemptions
  • Structural changes to roofs, load-bearing walls, or foundations

An owner-builder may be eligible to apply under Utah’s owner-builder rules. Confirm eligibility, required declarations and inspection duties with DOPL and the local authority; this is not an unrestricted alternative to contractor licensing. State in the contract who obtains permits and schedules inspections.

How Do You Apply for a Building Permit in Utah?

Application methods vary. For example, Washington City and St. George publish City Inspect portals; other authorities use different systems. Follow the current checklist for the property’s jurisdiction.

  1. Confirm your jurisdiction and portal. Cities like Salt Lake City run applications through the Citizen Access Portal, while other municipalities use ProjectDox or a county-specific email submission process. Call ahead if you’re unsure which system applies to your address.
  2. Create an account and select your permit type. New construction, addition, remodel, and accessory-structure permits each have separate application paths.
  3. Use the required file format. Washington City requires PDF uploads. Check your own authority’s file naming, drawing and upload instructions before submitting.
  4. Attach required supporting documents. This usually means a site plan, stamped structural drawings, and an engineering or soils report if your lot requires one.
  5. Sign and, if requested, notarize the application before it moves into the review queue.
  6. Confirm fees and payment stages. Ask whether a review deposit is required, when remaining charges are due and which amounts are refundable.

Pro Tip: Verify every fee notice directly through the official portal or a system like Teller before paying anything. Salt Lake City’s building department specifically warns homeowners to confirm invoices through the portal rather than trusting an emailed link, since scam notices have targeted permit applicants.

What Do Permits Cost, and How Long Do They Take?

Review times and fees are local and project-specific. Request the current fee schedule and review estimate from the authority serving the property. A published initial-review target is not a permit-issuance guarantee: intake, corrections, zoning, utilities and other approvals can add time.

  • Plan review: confirm any deposit, due date and refund policy.
  • Permit and related fees: request an itemized estimate, including any valuation-based fee, applicable state charge, impact fee or utility charge. Do not apply a flat percentage to the whole project budget.
  • Expiration: confirm commencement, inactivity and extension deadlines on the issued permit; do not assume a universal 180-day rule.
  • Changes or withdrawal: ask how revised scope, expiration or cancellation affects fees and approvals.

What Inspections and Certifications Do You Need for a Certificate of Occupancy?

A permit gets you started. A Certificate of Occupancy is what lets you actually move in, and it depends on a sequence of inspections plus a handful of third-party certifications that catch homeowners off guard late in the build.

  1. Footing and foundation inspection, before any concrete gets covered
  2. Framing inspection, once the structural shell is up
  3. Rough-in inspections for electrical, plumbing, and mechanical systems, before drywall goes up
  4. Energy compliance documentation and testing, including a blower-door test where required by the applicable code and serving authority.
  5. Final inspection, covering everything from egress windows to smoke detectors

Before occupancy approval, obtain the jurisdiction’s current final-inspection and closeout checklist. Washington City publishes new-home submittal and inspection requirements, but soils, energy, exterior-finish and other certifications depend on the project and authority. Arrange required tests and documentation early; no fixed delay is established here.

Pro Tip: Never cover work before its inspection is signed off. Utah County’s building department is blunt about the consequences: inspectors can require you to remove finished drywall or flooring to verify what’s underneath, which costs far more than the delay of waiting for the inspector.

How Do You Verify a Contractor’s License in Utah?

Verify license status and classification through Utah’s license lookup. Obtain insurance certificates separately and verify coverage with the insurer or agent. Put permit submission, revision and inspection responsibilities in the construction agreement.

Owner-builder eligibility and obligations must be confirmed before applying; obtain the local declaration and understand responsibility for compliance and inspections.

  • Check license status and standing through DOPL before signing a contract
  • Confirm general liability and workers’ compensation coverage
  • Ask who will physically pull the permit and manage inspections
  • Understand that owner-builder status shifts compliance risk onto you

What Causes Permit Delays, and How Do You Avoid Them?

Incomplete plans, missing professional signatures or reports and incorrect upload formats can delay intake or review. Follow the serving authority’s current checklist; Washington City specifically requires PDF uploads.

  • Use the jurisdiction’s checklist before submitting, not after a rejection notice
  • Confirm file format requirements (almost always PDF) ahead of upload
  • Schedule inspections as soon as each construction phase completes, not after
  • Budget time for third-party certifications rather than scrambling for them at the end

Pro Tip: Verify unexpected payment requests through contact information independently obtained from the official building department website. Do not assume an email is genuine or fraudulent solely because of its delivery method.

The Local Builder’s View on Permit Coordination

Permit review can involve code corrections, zoning, utilities and incomplete plans. Coordinating the drawings and field conditions can reduce avoidable corrections, but it cannot guarantee approval or timing.

Design meetings and renderings can help clarify scope. They do not replace coordinated construction documents, engineering or the authority’s review. Confirm which preconstruction deliverables are included in the agreement.

Official Permit Resources to Bookmark

Bookmark your local authority’s application, checklist, fee schedule and inspection pages. Utah adopts specified model-code editions with state and authorized local amendments; that is different from an unamended model code. The Utah code version effective July 1, 2026 includes the 2021 IRC and lists other adopted editions. Confirm the version and transitional rules applicable to the permit date with the serving authority.
