Douglas County's residential zoning does not set a single percent lot-coverage cap. Building bulk is controlled through setbacks, the 35-foot height limit, gross density, and detached-garage size caps (one garage up to 1,000 sq. ft. on lots under 1 acre).
Rather than a fixed impervious-coverage percentage, the Zoning Resolution manages residential building bulk through required setbacks, the 35-foot height limit, minimum lot area, and maximum gross density (for example, one dwelling per 2.5 acres in Estate Residential). Accessory buildings are limited directly: on lots under 1 acre a maximum of one detached garage of no more than 1,000 sq. ft. is permitted; on lots 1 acre or greater up to two detached garages totaling no more than 3,000 sq. ft. are allowed. Individual planned developments, subdivision plats, and HOA covenants may impose their own coverage or floor-area limits.
Exceeding accessory-building size caps or building beyond setback/density limits is a zoning violation that can block permits or require removal.
