Finishing a Basement in Layton
Layton is the largest city in the area, with homes from many decades. Basement projects here are as likely to be remodels as first-time finishes.
Layton homes and households
With about 83,000 residents, Layton is the largest city we cover. Census estimates put the median Layton home at about 1993, with roughly 37% built in 2000 or later. About seven in ten homes are owner-occupied, and households average about 3 people.

Layton is also home to Hill Air Force Base's South and East gates, according to the city. Older homes mean more basement remodels: reworking a dated finish, adding a legal bedroom where an old window falls short, or adding a bathroom. Newer neighborhoods bring more first-time finishes.

Layton's basement handout
Layton's FAQ says a permit is required to finish a basement. Applications go through the city's online portal with PDF plans and the project's valuation. The city's "Residential Basement Finish/Remodel" handout, updated January 2025 and based on the 2021 IRC, asks plans to show:
- The whole floor planTotal square footage, with ceiling heights.
- EgressEgress window sizes and window well dimensions. Wells deeper than 44 inches need a ladder.
- SystemsThe electrical, plumbing and mechanical layout, including smoke and carbon monoxide detectors.
- InsulationA minimum of R-13 in exterior walls.
The handout also summarizes the code minimums it checks: a 5.7 sq ft egress opening at least 24 inches high and 20 inches wide with a sill no higher than 44 inches, 9 sq ft window wells, 7-foot ceilings (6 ft 4 in under beams and ducts), interconnected smoke alarms, CO alarms, fireblocking and treated sill plates.
Inspections and fees
Layton's handout lists three inspections: a four-way rough, insulation and final, each with at least 24 hours' notice. The city's fee schedule, effective July 1, 2026, sets the permit fee from valuation:
| Project valuation | Permit fee |
|---|---|
| $2,001 to $25,000 | $69.25, plus $14.00 per additional $1,000 |
| $25,001 to $50,000 | $391.75, plus $10.10 per additional $1,000 |
Residential plan check adds 40% of the permit fee, and re-inspections are $50. Larger valuations follow the same schedule.
Basement apartments and ADUs in Layton
Layton requires a permit for every accessory dwelling unit. Its ADU handout, updated May 2026, says:
- ADUs are permitted in all single-family residential zones, one per lot;
- the owner records an agreement to live on the property and not rent both units;
- one parking stall is required in addition to the home's required parking;
- rentals must be 30 consecutive days or longer, and short-term rentals aren't allowed;
- a basement ADU keeps interior access unless the fire department approves other egress, and any separate entrance goes on the side or rear;
- the city lists no size limit for internal units, and permits are reviewed within 14 business days.
In September 2026 the city council took up ADU code amendments (Ord. 26-27) for new state law, mainly affecting detached units. The handout may not yet reflect them, so confirm current rules, including entrance location, before designing around a unit. See basement apartments and ADUs.
Hillside areas
Parts of Layton sit on slopes, and the Utah Geological Survey has documented landslides there, including one in 2001 that damaged six homes. That rarely affects interior basement work, but it matters if your plan adds a new exterior opening or walkout. Ask the city what review applies. See walkout basements.
