Planners urged cutting the overlay's R-1 height break. The sponsors kept it.

The Anchorage Planning Department asked in June that the Missing Middle Housing Opportunity Overlay drop its height exception for R-1, the zone that requires 6,000-square-foot lots. The sponsors have not dropped it. Property owners along Anchorage Bowl transportation corridors could opt in to building duplexes, triplexes, fourplexes, cottage courts and townhomes under the measure, AO 2026-85, which Assembly members Erin Baldwin Day and George Martinez introduced June 9. An overlay lets owners inside a mapped area opt in to standards that depart from their zone, without changing standards for other properties.

The sponsors' third headline element promises neighborhood-compatible height limits of 30 feet in R-1 and 40 feet elsewhere, unless the underlying zone allows taller buildings. Five days before introduction, the Planning Department finished a 14-page review recommending the department "remove the special dispensation for lower heights in R-1 sections of the overlay," writing that differing rules by zone "undermines the function and effectiveness of the overlay." The memo, dated June 4, runs from Long Range Planning Manager Daniel Mckenna-Foster to Planning Director Melisa R. K. Babb.

The department's numbers: an R-1 property today may cover 40 percent of its lot; under the overlay, coverage would rise to 70 percent. Minimum lot standards of 6,000 square feet and 50-foot width would fall to 2,133 square feet and 26.6 feet.

The department states it has not worked on the Transit-Supportive Development Overlay since that effort paused in October 2025, and that the Missing Middle proposal is "substantially similar to version six" of it, which the Planning and Zoning Commission recommended for approval with amendments on October 6, 2025, before the Assembly paused the broader effort. A comparison table tracks the retreat across versions: maximum height from 75 feet to 40, lot coverage from 100 percent to 80 and then 70, and minimum lot size from 1,400 square feet to none and then to the subdivision standard. Downtown Anchorage was dropped from the map after an earlier commission recommendation.

The department attaches a table of 21 projects it says the reform would have affected, drawn from October 2025 commission testimony and later comments and pre-application meetings. Six planned projects yielding more than 100 units were on the list a year ago. Several entries record developers taking slower paths instead, such as a duplex project off Hacienda Drive routed through a rezone from R-5 to R-2D. One institutional partner looked at a fire-damaged eight-plex with federal funding, could not wait for a non-conforming determination, and passed on the project, the memo states. One unnamed developer states that "rezones take over a year to complete and have a risk of not being approved even after a very expensive process."

The memo also floats an alternative the Assembly has not debated publicly: amending the 2040 Land Use Plan to allow the denser R-2M, R-3, R-4 or R-4A zones as implementing zones in the Transit Supportive Development designation. It says that since October 2025 the department has heard from residents both against zoning reform and for it, and names no one on either side.

The sponsors took the measure to the Assembly's Community and Economic Development Committee after an August 5 economic forecast on military housing demand, and their presentation still lists 40-foot heights "except in R-1." Which streets fall inside the overlay remains unclear, since the map is Exhibit A and the municipal agenda system hosting the ordinance and six of seven exhibits returned no data across repeated attempts September 1 and 2. The Assembly's housing page carries the memo itself and a summary of the ordinance. The Assembly holds a work session September 11 with no public comment; testimony opens at the hearing four days later, which the municipality says sponsors intend to continue to October 6.
