General Contractor in Eagle Mountain, Utah

Chapter 17.70 of the Eagle Mountain Municipal Code, amended most recently by Ordinance O-56-2025 on December 2, 2025, and the land use table in Section 17.25.030 set conditions for an ADU that include these.

• One ADU per residential lot, in an owner-occupied single-family home or in a detached accessory structure associated with a single-family home
• The owner living in the home or the ADU, apart from bona fide temporary absences
• Occupancy of the ADU limited to people related to one another by blood, marriage, or adoption, or else to no more than two unrelated individuals living as a single housekeeping unit, with no sublease of any part of the unit
• An ADU inside or attached to the home in any single-family zone, RA1 through RC, and a detached ADU in the RA1, RA2, RD1, RD2, FR, R1, and R2 zones, or in the R3 and RC zones on a lot of at least 8,000 square feet
• Every ADU entrance on the side or rear of the building, including the separate exterior entrance a basement ADU needs, with no internal connection to the home required
• The home's setbacks for an ADU built as an addition
• A height of no more than 35 feet for a detached ADU, with a standalone unit limited to two stories
• A detached ADU with 400 to 1,200 square feet of living space and no more than two bedrooms, on a site-built permanent foundation, with permanent utility connections
• The home's front, side, and rear setbacks for a detached ADU, and a separation of at least 6 feet from the home
• At least 70 feet of street frontage for a detached ADU, or less where the approval authority finds the lot's configuration or the home's size or location unique and the impacts on neighbors and the street substantially similar to those of a 70-foot-wide lot
• An exterior that keeps, to the degree reasonably feasible, the look of a single-family home, with a detached ADU's style, materials, and colors consistent with the home, or matching the garage for a unit above a detached garage
• Separate utility meters allowed for a detached ADU, with all municipal utilities in the owner's name
• Off-street parking for two vehicles on a hard surface for the ADU's tenants, with driveway space in front of a garage counted only when the ADU is in that garage and the home's required enclosed garage parking is provided elsewhere on the property, and with no occupant parking on the street along a neighboring property's frontage
• The home's address number for the ADU, labeled unit B, posted where it is visible on the street side of the home
• No rental for less than 30 consecutive days
• An ADU permit from the Planning Department for every new ADU and for any existing unit the city never permitted, in addition to every required building permit, including one for a basement finished earlier without a permit
• An ADU application with the owner's signed agreement to occupy the home or the ADU, apart from bona fide temporary absences, and to meet the chapter's standards; a site plan showing the required off-street parking and the utility meters; a floor plan labeling the use of each room; and evidence of the building permit
• Exceptions to the chapter's standards only by Planning Commission approval after a public hearing, and none for the number of units, owner occupancy, permanent utility connections, permanent foundations, building permit requirements, exterior appearance, off-street parking, addressing, or short-term rentals
• An ADU permit that stays valid through a sale or transfer of the home while the unit complies with the city's ordinances and conditions of approval

The Planning Department asks for an ADU permit when the unit will be rented to someone who is not related to you, and for a recorded Second Kitchen Agreement when it will not be rented. The department takes ADU applications online. Each one includes a site and parking plan, a floor plan, and an ownership affidavit. The department's ADU Checklist states that ADUs are allowed only in single-family homes and are prohibited in townhomes, duplexes, and all other multifamily dwellings. The checklist's site plan items include the location and dimensions of the two off-street parking spaces, the utility meter locations, and a 36-inch-wide unobstructed path from the ADU exit to the street or sidewalk. The floor plan items include the kitchen sink and the 220-volt outlet or gas line for the stove.

Chapter 17.69, adopted by Ordinance O-33-2024 on July 16, 2024, covers any added kitchen or kitchenette, in the home or in an accessory structure, that is not part of an ADU and has at least a water connection and a 220-volt outlet or gas connection. The chapter sets these conditions.

• One front entrance, one address, and one of each utility meter for the home
• Interior access kept open to every part of the home, with no keyed or deadbolt lock between the added kitchen and the rest of the house
• An added kitchen in the home or in an accessory structure only where no second dwelling unit or ADU is established in either
• Residents allowing city staff, on request and within reasonable hours, to inspect the home and any accessory structure with an added kitchen
• An agreement, signed by the owner and recorded with the Utah County Recorder before the building permit is issued, that the home and any accessory structures on the property will not be converted into two or more dwelling units except as the city's land use title allows
• Family occupancy only, for present and future owners alike, apart from live-in help such as a nanny or an in-home nurse
• Construction to the adopted building code, with a city building permit before the work begins where one is required

If the owner later receives an owner-occupied ADU permit, the agreement's limits become void.

Utah's ADU statutes apply in Eagle Mountain as well, as our ADU page explains.
