Book a callAccessory Dwelling Units (ADUs) are becoming increasingly popular across the United States, offering homeowners and real estate investors alike a unique opportunity to maximize their property's value and utility. Salt Lake City, with its bustling urban development and scenic landscapes, is no exception. But, can you legally build an ADU in Salt Lake City? This blog post dives into the nitty-gritty of ADUs in this vibrant city, from zoning laws to potential returns on investment.
Accessory dwelling units, also known as mother-in-law apartments or granny flats, are secondary living spaces built on the same lot as an existing single-family home. These units offer a promising solution to the housing crunch, providing additional housing options while preserving the scale and character of established neighborhoods. By allowing for more density without dramatically altering the neighborhood's streetscape, ADUs present a balanced approach to addressing the growing demand for housing. The rise in ADU popularity is largely due to their versatility, offering additional living space for family members, a source of rental income, or both.
In Salt Lake City, the movement toward more flexible housing options has seen significant strides. Recent changes in zoning laws have made it simpler for homeowners to add ADUs to their properties. However, there are still guidelines and restrictions to be mindful of. For instance, ADUs must meet certain size and height requirements, and the property must have sufficient parking. The permitting process involves submitting detailed plans and obtaining approvals from the city planning department, a step crucial for ensuring your project aligns with local regulations.
Building an ADU in Salt Lake City can offer tangible financial benefits, such as additional rental income and increased property value. They are an excellent way to leverage your property to generate passive income.
ADUs can help address the housing shortage in urban areas by providing affordable living options. They also allow homeowners to keep aging family members close or provide living space for caregivers.
Smaller in size, ADUs typically require less energy to heat and cool than traditional homes, contributing to a reduced carbon footprint. Also, by increasing housing density in urban areas, ADUs can help limit urban sprawl.
ADUs, whether attached or detached, must comply with all accessory building requirements related to yard setbacks, bulk, and height limitations. Any additions to the primary dwelling must also meet the bulk requirements applicable to the principal structure.
ADUs are permitted on properties located within residential zoning districts.
Only one ADU is allowed per residential lot, and it cannot be sold separately from the primary dwelling.
If the property has a single-family dwelling, either the main house or the ADU must be occupied by the owner or an immediate family member.
Properties situated within designated Historic Districts require a Certificate of Appropriateness from the Historic Landmark Commission.
The Commission can modify certain lot and building standards to ensure compatibility within the historic neighborhood.
Building Coverage Limits
ADUs must comply with the maximum building coverage requirements specified by the underlying zoning district or applicable overlay district, whichever is more restrictive.
The rear yard is defined as the area between the primary dwelling's rear wall and the rear property line.
In single and two-family residential districts (R-1, R-2, and SR), accessory buildings, detached garages, sheds, and ADUs combined cannot cover more than 50% of the rear yard area.
The ADU's size cannot exceed the primary dwelling's size, with a maximum allowance of 1,000 square feet, whichever is smaller.
At least one additional parking space must be provided on the property, which can be accommodated in the existing driveway. However, this requirement may be waived if the property is located within a quarter-mile radius of a public transit stop or within a half-mile radius of a designated bike path.
While zoning regulations do not specifically govern the location of ADU entrances, building and fire code requirements must be met.
Specific guidelines apply to window placement on the second story of detached ADUs to maintain privacy for neighboring properties. These include restrictions on window locations adjacent to side or rear property lines, unless certain conditions are met, such as clerestory windows, windows facing the principal building, or windows facing commercial or non-residential zones.
Decks and patios associated with detached ADUs are subject to height and setback regulations. Rooftop patios are prohibited, while covered patios are allowed with size limitations. Balconies on ADUs are permitted, provided they do not extend into required setbacks and meet specific dimensional requirements.
If a detached ADU is located within 15 feet of a public alley, additional requirements may apply to promote alley activation and safety. These may include exterior lighting, a pathway from the alley to the ADU entrance, and gate provisions if fencing is present.
It is essential to consult with the city's planning department and review the specific zoning regulations applicable to your property before undertaking an ADU project. Compliance with these regulations is crucial to ensure a successful and code-compliant ADU construction.
