Anchorage could shrink its minimum lot size by two-thirds under a pending ordinance

The smallest lot Anchorage allows in its single-family zone is 6,000 square feet. Under an ordinance before the Assembly, it could be 2,133. Buildings could cover 70 percent of a lot instead of 40 percent. The public hearing is Sept. 15.

One limit shapes how far that reaches. A lot already sitting at the 50-foot minimum width could not be subdivided, so the change would apply to oversized lots rather than to the standard one.

Inside the overlay's boundaries, height would be capped at 40 feet, or 30 feet in the single-family zone. There would be no front setback requirement, side setbacks of five feet or none at all along a shared lot line, and no rules on private open space or on stepping buildings down next to shorter neighbors. Where the overlay and existing zoning conflict, the more permissive of the two generally wins.

Assembly Members Erin Baldwin Day of Midtown and George Martinez of East Anchorage sponsored what they call the Missing Middle Housing Opportunity overlay. The Assembly introduced it unanimously on June 9. A work session is set for Sept. 11, four days before the hearing.

The city's own planning staff have objections to this version. Long-range planning manager Daniel Mckenna-Foster wrote in June that carving out special rules for particular underlying zones undermines the overlay, and recommended dropping the 30-foot exception for single-family areas. The hearing text keeps it. Baldwin Day has defended that, pointing to shadow concerns raised during an earlier overlay debate.

Earlier drafts set a density target of 35 or 36 dwelling units per acre. This version names no number at all.

The proposal has a longer history than its June introduction suggests. It started as a planning commission case, and the commission voted 6-2 in October 2025 to recommend approval — while its chair said the ordinance was not expected to pass without more work, and its vice chair questioned whether the recommendation would hold up to public scrutiny. Graham Downey, deputy chief of staff to Mayor Suzanne LaFrance, said the process would then pause for talks about building 10,000 homes in 10 years.

The planning department has not worked on it since that vote. The text now before the Assembly closely resembles the sixth draft of the paused version, and the current planning commission has not reviewed it. The department's June memo counts 21 projects and inquiries that would use the overlay, up from at least six a year ago, and recommends aligning the proposal with the comprehensive plan or amending the 2040 Land Use Plan instead.

Two things are hard for a resident to find out before the hearing. Whether a given block falls inside the overlay appears only in an exhibit map. And 39 people testified at the 2025 commission hearings, but the minutes do not record what any of them said.
