The City is updating its Accessory Dwelling Unit (mother-in-law apartment) regulations. What do you think of the proposed changes?
The Salt Lake Council and Mayor's Administration have been working for years to improve City regulations for Accessory Dwelling Units (ADUs). ADUs are small apartments that share a lot with a single-family home. ADUs can be entirely separate buildings (figure 1 below), above and inside garages (figure 3), or basement apartments (figure 2). Currently, permits for new ADUs are only available for properties located a half mile or less from a fixed rail transit stop for Front Runner, TRAX, or the S-Line, and only 25 permits can be issued per year.
Below are the major amendments the Council will soon consider. (Find more information and details on our current proposals page:
Allowing ADUs citywide – instead of only within certain boundaries.
- ADUs would be a conditional use in the FR (Foothill Residential District) and R-1 (Single Family Residential) zoning districts. These are the zoning districts that only allow detached single family dwellings.
- ADUs would be a permitted use in all other residential zoning districts that already allow duplexes, triplexes, and multi-family as permitted uses. (SR-1, SR-3, R-2 RMF-30 RMF-35, RMF-45, RMF-75, RB R-MU-35, R-MU-45, R-MU, and RO).
- Eliminating the permit limit of 25 new ADUs per year in the City.
- Requiring properties with ADUs to have a deed restriction stating that an owner must occupy the property.
Why is the Council considering these changes?
Allowing more residents to have ADUs on their properties can be beneficial. ADUs, when designed and managed responsibly, can:
- Create new housing units
- Provide more housing options in residential areas
- Allow more efficient use of existing housing stock
- Support affordable housing options
- Support transit oriented development and reduce automobile dependency
- Support economic viability of historic structures
- Support aging in place for older residents
ADUs can also present challenges, including:
- Impacting the character of single-family residential neighborhoods through increased density
- Increasing traffic and parking issues
- Enforcing the ordinance and monitoring for these impacts
The Council wants your feedback on the latest proposed changes. Public Hearings will be held October 2 and October 16 at 7 p.m. in room 315 of the City & County Building, 451 south State Street, Salt Lake City, Utah.
