Anchorage residential setbacks in R-1 zones are typically 25 feet front, 5 feet side, and 10 feet rear. Setbacks vary by zoning district and may be relaxed for infill under 2023 Title 21 reforms.
AMC Title 21 governs zoning setbacks. Standard R-1 single-family setbacks are 25 feet front, 5 feet side, 10 feet rear. R-2A duplex districts allow 20 feet front setbacks. Title 21 was overhauled in 2013 and amended through 2023 to encourage infill and ADU development; several districts now permit reduced setbacks for compliant accessory units. Corner lots have dual front setbacks on both street frontages. Variances are available through the Planning and Zoning Commission with published findings.
Setback encroachments: stop-work, removal of encroaching structure, or after-the-fact variance (not guaranteed).
