Digging from the back of the sidewalk into the road, or connecting to a city utility, takes an excavation permit. Public Works inspections are scheduled through the Public Works office.

One accessory apartment per lot
An internal accessory apartment in any residential zone except the SDP-1 and R-2-B zones, on a legal lot of record of 6,000 square feet or larger

A detached unit's front wall at least 10 feet behind the front wall of the house
The accessory building rules of Section 18.84.230 for a detached unit, among them accessory buildings that together cover no more than 20 percent of the rear yard, no reflective roof material such as unpainted metal, and all roof drainage kept on site
At least one off-street parking stall for the apartment beyond the home's required parking, inside a garage only where at least two other garage stalls are available for the home, and never directly behind one of the home's required stalls
No more than one of the apartment's designated stalls in the front yard setback or in a side yard setback next to a street
Each designated stall paved with asphalt or concrete, or with another hard surface material that will not generate dust or allow mud to be tracked onto city streets
An accessory apartment permit application to the Community Development Department before construction or occupancy
No new address, with the home addressed "A" and the apartment "B"

What Homeowners Ask

Mapleton Remodeling and Permit Questions

Can I build a detached accessory apartment in Mapleton?

Yes, on a property of at least 11,000 square feet, a minimum that Ordinance 2026-09 lowered from half an acre on June 3, 2026. The full-time resident owner lives in the house or the apartment, and the unit's interior floor area is capped by lot size, from 1,000 square feet up to 1,400 square feet on three acres or more.

Does a second kitchen need a building permit in Mapleton?

Yes. Section 18.84.415 of the city code requires a building permit for each new kitchen added to an existing home or accessory building. A new home or accessory building needs only one permit when every kitchen is shown on its drawings.

What does building in Mapleton's CE-1 zone require?

Under Chapter 15.45 of the city code, amended in March 2026, every proposal in the CE-1 Critical Environment Zone to grade, fill, or excavate land, or to erect a structure for human habitation, goes to the City Engineer. The site plan goes in with a geotechnical and geology report whose site-specific investigation includes trenching as well as boring, a soils report, and a fire protection report, each certified by an engineer licensed in Utah. It also goes in with footing and foundation plans certified by a structural engineer licensed in Utah and approved by the City Engineer, among the other technical plans the chapter lists.

How far ahead are Mapleton inspections requested?

The city's Building Inspection Summary asks for requests up to three days in advance when a specific date or time is preferred. Every inspection can be scheduled through MGO Connect.
