Anchorage, AK zoning map & districts

Anchorage is a unified home-rule municipality — city and borough government merged into one — so its Title 21 land-use code applies areawide, with no separate city-versus-borough zoning split to navigate. Title 21 was comprehensively rewritten and adopted in 2014, consolidating zoning, subdivision, and design standards into a single integrated code administered by the Planning Division of the Office of Community Planning and Development.

How zoning works in Anchorage

The district table runs from a dozen-plus graduated residential classes (R-1 through R-10, with letter suffixes distinguishing lot size and housing type) through neighborhood and general business districts, a dedicated three-tier Downtown district set (DT-1 through DT-3), and light/heavy industrial classes, plus special districts for public lands, airport, and watershed areas reflecting Anchorage's mix of urban core and undeveloped municipal land. Anchorage permits ADUs under its residential-district use tables, subject to lot and owner-occupancy standards that vary by district.
