Takoma Park, MD Building Setbacks & Zoning: Lot Coverage Limits (2026)

Montgomery County Zoning Ordinance limits lot coverage in R-60 residential zones to 35 percent of the total lot area. Coverage includes the footprint of the principal dwelling, garage, accessory structures, driveways, walkways, patios, and other impervious surfaces. Pervious pavers and green infrastructure may receive partial credit toward reducing the calculated lot coverage depending on the material type and installation method. The county's stormwater management regulations under Chapter 19 of the County Code require that any project adding more than 5,000 square feet of impervious surface submit a stormwater management plan. Takoma Park has adopted additional environmental standards encouraging rain gardens, permeable materials, and tree canopy preservation. Properties seeking to exceed the 35 percent coverage limit must obtain a variance from the Montgomery County Board of Appeals, which requires demonstrating that strict compliance creates an undue hardship. The city's Community Development Department can advise on local requirements before a county application is filed.
