Anchorage R-1 maximum lot coverage is typically 35 percent for the principal structure. Impervious surface and accessory structures add additional limits. Larger lots may have lower percentages.
AMC Title 21 caps lot coverage in R-1 single-family zones at approximately 35 percent of lot area for all buildings combined. R-2 and R-3 allow higher coverage up to 50 percent. Accessory structures like sheds and detached garages count toward total coverage. Impervious surface rules administered by the stormwater program can further limit driveways and patios, especially in sensitive watersheds like Campbell Creek. Pervious pavers and green stormwater controls can offset some impervious area.
Over-coverage requires variance or structure removal.
