Anchorage Title 21 zoning controls house size through floor-area ratio, lot coverage, height, and setback rules rather than a single mansionization ordinance, with stricter standards in established neighborhoods like Turnagain and South Addition.
Title 21 districts each set maximum lot coverage (often 35-50% in residential), height limits (typically 35 feet in R-1 and R-2), and setback envelopes that effectively cap home size on a given lot. Several neighborhood overlays add further controls to preserve character, including limits on second-story additions or front-facing garages. The 2013 Title 21 rewrite consolidated these tools, and amendments continue. There is no Los Angeles-style anti-mansionization ordinance with a hard floor-area ratio cap, but the cumulative envelope works similarly.
Permit denial for over-bulk plans, stop-work orders, mandatory redesign or removal of noncompliant additions, and code-enforcement fines until brought into compliance.
