Woodbury, MN Building Setbacks & Zoning: Lot Coverage Limits (2026)

Woodbury's zoning ordinance regulates lot coverage through "maximum building coverage" rather than a single citywide impervious-surface standard. Section 24-132(f)(10) caps building coverage at 35 percent in the R-1 urban reserve district, section 24-133(f)(10) sets the same 35 percent ceiling in the R-2 single-family estate district, and section 24-134(f)(10) applies it again in the R-4 urban residential district, the city's primary platted single-family zone. The standard is measured against the footprint of principal and accessory structures on the lot, not landscaping or driveways, and it is checked by city staff during building permit and site plan review.

A separate, tighter impervious surface limit applies only to nonconforming lots of record inside the shoreland overlay district near Woodbury's lakes, streams and wetlands: section 24-33(b)(1)c and (b)(2)c caps impervious surface, defined in the code as any constructed hard surface that prevents water from entering the soil, at 25 percent of the lot for those shoreland parcels, and requires a Type 1 sewage treatment system or public sewer connection before that reduced coverage is allowed. Outside the shoreland overlay, commercial and institutional districts such as B-1 office park and MC medical campus use a more permissive 70 percent impervious surface coverage standard, so a homeowner should not assume the commercial figure applies to a house lot.

Any proposal that would push a residential lot over its 35 percent building coverage cap needs a variance from the board of adjustments and appeals, which requires proof of a practical difficulty unique to the property, not simply a desire for a larger addition or garage.
