Full Breakdown

10(7) of the City of Middleton Municipal Code lists the Density, Intensity, and Bulk Regulations table for the SR-L Single-Family Residential Low Density district, the City's standard single-family zone with a target density of six units per acre. The table sets a Minimum Front Setback of 20 feet, a Minimum Street Side Setback of 20 feet on corner lots, a Minimum Side Setback of 8 feet for interior lots, and a Minimum Rear Setback of 25 feet. Two additional dimensional rules interact with the yard setbacks: a front-loaded attached garage cannot project more than 5 feet in front of the plane of the principal structure, and any porch built in a front or street-side yard on a corner lot gets a reduced 8-foot setback rather than the full 20-foot yard minimum, encouraging usable front porches without pushing the whole house back.

A separate pavement setback applies to driveways and other paved surfaces: 2 feet from side and rear lot lines and 10 feet from any street right-of-way, distinct from the building setback. 10, cross-references directly, requiring all structures to comply with the requirements listed for each zoning district in Article II. Other residential districts in Middleton carry different numbers under their own Article II sections; for example, some of the City's higher-density single-family zones use tighter 15-foot front setbacks with alley-served rear setbacks as low as 3 feet, so a homeowner must check the table for the specific zoning district before assuming SR-L's figures apply to a different lot.

Violations & Fines

Building or fencing an addition, garage, or other structure into the required front, side, or rear setback without an approved variance from the Board of Zoning Appeals is a Zoning Ordinance violation, enforceable by the Zoning Administrator under Section 10.10.60, and can require the structure to be relocated or removed to restore the required yard.

Frequently Asked Questions

What is the front yard setback in Middleton's SR-L district?
20 feet, under City of Middleton Municipal Code Section 10.02.10(7). Corner lots also carry a 20-foot minimum street-side setback, while the interior side setback is 8 feet and the rear setback is 25 feet.
Can I build a porch closer to the street than the setback in Middleton?
Yes, within limits. Section 10.02.10(7) sets a reduced 8-foot minimum porch setback for front and street-side yards on corner lots in the SR-L district, smaller than the full 20-foot building setback.
Do all Middleton residential districts use the same setbacks?
No. Each zoning district has its own Density, Intensity, and Bulk Regulations table in Article II. SR-L requires a 20-foot front setback, while some of the City's higher-density districts allow front setbacks as low as 15 feet with alley-served rear setbacks down to 3 feet.
