General Contractor in Syracuse, Utah

For an accessory dwelling unit, Section 10.30.020(E) of the Syracuse Municipal Code, last amended by Ordinance 25-30 on July 8, 2025, sets conditions that include these, in its own order.

• An ADU inside, attached to, or detached from the principal dwelling, on a lot where a single-family home exists, in the residential zones the section lists
• An owner occupant living on the property, in the principal dwelling or the ADU, apart from a bona fide temporary absence of three years or less for an activity such as military service, a temporary work assignment, a sabbatical, or voluntary service, or a stay in a hospital, nursing home, assisted living facility, or similar place providing regular medical care, retirement facilities and communities excluded
• A deed restriction stating the owner occupancy requirement, on a form the City Attorney approves, filed with the county recorder before the city issues the ADU's building permit and running with the land until the ADU is discontinued, abandoned, or revoked
• One ADU per single-family residential lot
• The underlying zone's rules for a principal building unless the section provides otherwise, with an existing accessory structure that misses the setbacks in those rules convertible to an ADU if it grows no more noncomplying, and new construction outside the main house held to the standards for accessory structures and to fire separation requirements
• A single-family dwelling on the lot, already standing or built with the ADU
• A lot meeting the zone's minimum size for an internal or attached ADU, and at least 10,000 square feet for a detached one
• No separate utility connections for an internal ADU
• No nightly or weekly rental of either unit
• Minor and major A home occupations in an ADU only for businesses with no client visits to the property
• An internal unit in a basement or attic, or an attached one, of no more than 50 percent of the principal dwelling's gross square footage; a detached unit no larger than the main house's footprint or 1,500 square feet of gross living area, whichever is smaller; and every ADU at least the size the adopted building code requires
• No separate sale or subdivision of the ADU
• No more residents than the code allows for a family
• One more on-site, off-street parking space, never tandem, for an internal ADU or an attached or detached studio or one-bedroom unit, and two more, tandem allowed, for an attached or detached ADU with two or more bedrooms, its parking kept independent of the household's spaces
• An internal or attached ADU allowed to use an existing entrance on the home's street-facing front facade, any new street-facing access for it at least 20 feet behind that facade, and the same distance for a detached unit's street-side door
• Height and setbacks under the accessory building standards of Subsection (F)
• A minor conditional use permit, with a Land Use Administrator's denial appealable to the Planning Commission
• A building permit for every ADU, however it is created, and no one living in it before the owner holds that permit and a certificate of final occupancy from the city

As of October 22, 2026, Syracuse had adopted no amendment to Section 10.30.020 after Ordinance 25-30. Utah's ADU statutes apply in Syracuse as well, as our ADU page explains.
