Eagan, MN Building Setbacks & Zoning: Setback Rules (2026)

City Code Sec. 11.60, Subd. 5(E) sets the R-1 bulk standards table: minimum lot area of 12,000 square feet, minimum lot width of 85 feet, a 30-foot setback from any public right-of-way, a 10-foot side yard setback for the principal structure, a 5-foot side yard setback for a garage or accessory structure, a 15-foot rear yard setback for the principal structure, and a 5-foot rear yard setback for an accessory structure. Subd. 5(F) adds that in all residential districts, every one of those minimum setbacks grows by three feet for each foot a building's height exceeds 35 feet, so a taller custom home pushes its own setback lines outward.

Separate from the interior lot-line setbacks, Subd. 5(G) layers on road-based setbacks along any interstate, state highway or thoroughfare: 50 feet or 125 feet from the right-of-way centerline (whichever is greater) along a Principal or A Minor Arterial, and lesser distances along Minor Arterials and Collectors. Sec. 11.40, Subd. 4 lists what does not count as an encroachment: air conditioners, chimneys, sills and similar features projecting less than 30 inches into a required yard, and decks or patios extending no more than 30 inches above grade and limited distances into front, side or rear yards.

The Community Development Department's building permit review checks proposed footprints against this table before a permit issues, and any structure sited closer to a lot line than these standards allow needs a variance from the city council sitting as the board of adjustments and appeals.
