Basement finishing in Mapleton

Thinking about a Mapleton basement apartment?

Mapleton updated its accessory apartment code in June 2026. Internal apartments, like a finished basement unit, are allowed in all residential zones except SDP-1 and R-2-B. The lot has to be at least 6,000 square feet.

The owner has to live in the house or the apartment, as shown on the Utah County tax rolls. The apartment door has to be on the side or the back of the home. It also can't change the look of the house as a single-family home.

Those rules decide where your stairs, door, and window wells go. We sketch the layout with them in mind, even if you only want a family room today. That keeps the rental option open for later.

Census data shows about 6 in 10 Mapleton homes were built in 2000 or later. If yours is one of them, Dakota can walk the basement and price both options.

Mapleton basement rules

Parking, address, and air in a Mapleton basement.

These come from Mapleton City Code 18.84.410, the city's inspection guide, and state radon data. We confirm the current rules with the city before your permit goes in.

One extra parking stall

A Mapleton home with an apartment needs one more off-street stall, paved, just for the apartment. It can only be in the garage if two other garage stalls stay free for the main house.

No new address

Mapleton will not give the apartment its own address. The code says to use the house address, with A for the main home and B for the apartment.

Book inspections online

Mapleton books inspections through the MGO Connect portal, up to three days ahead. If the work is not ready, the city charges a $55 re-inspection fee. We book each one only when the work is ready.

Check the radon level

The state's environmental quality office reports high radon in one of every three homes in Utah. The EPA says to act at 4 pCi/L or more. A low-cost test before framing helps you decide on a radon system.

Good questions

Mapleton basement finishing questions.

Can I put an apartment in my Mapleton basement?
In most cases, yes. Mapleton allows internal accessory apartments in all residential zones except SDP-1 and R-2-B, on lots of 6,000 square feet or more. The owner must live on site, and you apply for an accessory apartment permit first.
Do the apartment rules apply if my family lives downstairs?
No. Mapleton's code says the apartment rules do not apply when only family members live in the home. A basement for your own kids or parents is a regular basement finish with a building permit.
Where can a basement apartment entrance go in Mapleton?
On the side or the back of the house. Mapleton code says the apartment can't change the home's look as a single-family house. We plan a side or rear stairwell to meet that.
How do I schedule basement inspections in Mapleton?
Through the MGO Connect portal, where Mapleton takes permits and inspections. You can book up to three days ahead. We book each inspection and meet the inspector.
What does the Mapleton insulation inspection check?
Mapleton's inspection guide says it confirms that insulation, doors, windows, and heating and cooling equipment meet the current energy code. It comes after framing and rough-ins are checked.
