Typical Utah residential construction requires a building permit (for new construction, additions, structural modifications, and most significant remodeling), a mechanical permit (for HVAC work), an electrical permit (for new circuits, panel upgrades, and significant electrical work), and a plumbing permit (for new rough-in, water heater replacement in some jurisdictions, and DWV work). Some jurisdictions combine trade permits with the building permit; others issue them separately. Special reviews required in some circumstances include: WUI fire zone review (Sandy, Draper, Cottonwood Heights foothills), HOA design review (many Wasatch Front communities), soils/geotechnical review (hillside lots, expansive soil sites), and flood zone compliance for properties in FEMA Special Flood Hazard Areas. RainFire Builders identifies every required permit before mobilization and manages all applications.
