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

Section 1004.09(c) of the Roseville City Code regulates lot coverage in the Low Density Residential (LDR) district through an improvement area limit. The improvement area includes paved surfaces, the footprints of principal and accessory buildings, and other structures like decks, pergolas and pools, and it is limited to 50 percent of the parcel area. The stated purpose is to allow rather liberal construction on a residential property while preventing over-building. Subsection (c)(1) excludes yard ornaments, fences, retaining walls, gardens, planting beds and other landscaping from the term improvements.

A second, tighter cap sits inside the first. Subsection (c)(2) limits impervious surfaces to 25 percent of the area within a shoreland management overlay district, or within the stormwater management or wetland protection overlay districts regulated in title 8, to mitigate surface water impacts caused by excess stormwater runoff. Subsection (c)(3) limits impervious surfaces to 30 percent of the parcel area for all other parcels, a limit meant to prevent problems caused by excess stormwater runoff.

The 30 percent figure is not absolute. It can be exceeded, within the allowed improvement area, by receiving approval from the city engineer, who reviews a technical analysis of building materials, soils, slopes and other site conditions showing that the runoff from additional hard surfaces is mitigated. The 25 percent figure in overlay districts carries no such exception in the text.

The Low to Medium Density Residential (LMDR) district in section 1004.10(c) uses the same structure with larger numbers: a 60 percent improvement area limit, the same 25 percent cap in the shoreland, stormwater and wetland overlays, and a 35 percent impervious cap for all other parcels. Section 1011.05 separately requires lots to be used consistently with the zoning district and says yard requirements follow the district in which the lot sits.
