Benefits  Provide a variety of housing options  Enable self-sufficiency for individuals  Promote opportunities for extended family living  Implement a creative strategy for infill housing development

Existing ADU policies  Within the Multi-Modal Transportation District (MMTD): a single ADU, attached or detached, may be placed on any single-family or duplex parcel. Non-residential uses may have an attached ADU.  Outside of the MMTD: permitted in all zoning districts attached to or within principal structure, or within an existing detached garage.  City-wide: cannot exceed one-third (1/3) the area of the principal use and is limited to a maximum of 750 square feet when accessory to a residential use, or 1,000 square feet when accessory to a non-residential use.

Challenges  Scaling of size restrictions  Geographical limitations for detached ADUs Analysis and Observations  Within the MMTD at least half of the parcels analyzed would be limited to an ADU of less than 500 square feet under current code maximum of 33 percent of the principal structure.  Outside of the MMTD at least half of the parcels analyzed would be limited by the current code maximum of 750 square feet.  Increasing the size restriction to 40 percent of the principal structure allowed for more than half of the homes within the MMTD to be eligible for at least a 500 square foot ADU.

Policy Considerations/Staff Recommendations  Revise language to use the term “accessory dwelling unit” rather than “accessory apartment” for consistency  Allow detached accessory dwelling units with single-family residences city-wide  Allow for accessory dwelling units to be up to 40 percent the square footage of the principal structure  Allow for single-family homes to be eligible for a 500 square foot ADU, regardless of principal structure size  Increase the maximum ADU size to 800 square feet (consistent with the current Leon County Zoning Code)
