Commission adopts updated downtown single-family overlay: reduced front- and side-yard setbacks, discretionary alley relief

The Planning & Zoning Commission on Oct. 27 approved an ordinance package to repeal an older subsection of the zoning code and readopt a revised downtown single-family overlay as a standalone code section (405.43).

Staff said the amendment responds to several property- and lot-configuration issues in the older downtown neighborhoods where narrow historic lots and unimproved "paper" alleys prevent homeowners from making modest additions or adapting older houses. Under the adopted changes, front-yard setbacks for inhabitable building space (living rooms, bedrooms) within the overlay would be reduced from 25 feet to 15 feet; garage/front-of-driveway requirements remain at 25 feet to preserve on-street pedestrian and sidewalk clearance. Side-yard setbacks would be reduced from 7.5 feet to 5 feet. The amendment also creates a formal route for the commission to grant setback relief (including reduction to zero) on a case-by-case basis for lots that back to alleys, vacated streets or unapproved easements.

Proponents said the changes are intended to allow modest additions and to reduce the need for costly street-alley vacation proceedings. Commissioners asked staff to ensure the revised section appears prominently in the city code index and that the map boundary describing the overlay be clear; the commission voted to repeal the old subsection and to adopt the new section.

The commission—s action was procedural; formal ordinance adoption will move through the Board of Aldermen process. If approved at the aldermanic level, the change will allow property owners within the overlay to seek smaller setbacks for living space and to request limited relief where alleys or easements create practical lot-configuration obstacles.
