Finishing a Utah basement — what to plan before the framing starts.

Before you design: moisture and radon

• Check for water first: stains, efflorescence on the walls, or damp carpet in spring. Fix grading, gutters or drainage before you cover the walls.
• Test for radon. Utah has areas with elevated radon levels, and the Utah Department of Environmental Quality recommends testing. If levels are high, a mitigation system is easiest to install before finishing.
• Note where the furnace, water heater, panel and cleanouts are. They need access space, which shapes the layout.

Bedrooms need egress

• Under the building code Utah uses (the International Residential Code with state amendments), a basement bedroom needs an emergency escape opening, usually an egress window with a window well.
• The opening has to meet minimum size and maximum sill-height rules. Cutting a new egress window into a foundation wall is structural work that needs a permit.
• A room without legal egress cannot be called a bedroom, and that matters for safety, appraisal and resale.

Permits and inspections

• Finishing a basement normally needs a building permit, plus electrical, plumbing and mechanical work under that permit.
• Expect inspections at framing and rough-in (before drywall), insulation in many cities, and final. Your contractor should pull the permit and schedule inspections.

A realistic timeline

• Design and permit approval come first; the time depends on your city.
• Construction then moves through framing, rough-in, inspection, insulation, drywall, finishes and final inspection. A bathroom, kitchenette or egress window adds time.
• Ask for a written schedule with your estimate so you can plan around it.
