Summary
Allen County's Zoning Ordinance defines lot coverage as the portion of a lot covered by buildings but does not set a numeric maximum coverage percentage for single-family residential lots. Buildable area is controlled through yard setbacks and minimum lot size instead.
Lot Coverage: That portion of a lot that is covered by buildings.
Full Breakdown
The Allen County Zoning Ordinance defines "lot coverage" as that portion of a lot covered by buildings. Unlike many jurisdictions, the county's residential districts (such as R1) do not cap coverage with a maximum percentage; instead, how much of a lot you can build on is governed by the required front, side, and rear yard setbacks, minimum lot area, and accessory-structure rules (an accessory structure's total square footage must be less than the primary building). In practice, the setback envelope and minimum lot size determine buildable area. Confirm your parcel's zoning and any overlay-district requirements with the Fort Wayne-Allen County Department of Planning Services before building.
Violations & Fines
Building into a required yard or exceeding accessory-structure size limits is a zoning violation enforced by DPS; a variance may be required.
