Summary
Single-family lots in Parker cap total building footprint at 20% of lot area under City Code § 156.32(C)(2), and accessory buildings alone cannot exceed 10% of the lot. On the district's 2-acre minimum lot, that ceiling works out to 17,424 square feet of above-ground structure.
(2) Maximum lot coverage. The maximum lot coverage by all above ground structures shall be no more than 20%. For a 2-acre lot, this is a maximum of 17,424 square feet. (3) Nonresidential structures; maximum lot coverage. No more than 10% of the total lot area may be accessory buildings.
Full Breakdown
32(C)(1). 32(C)(2) limits the combined footprint of all above-ground structures, house plus every accessory building, to no more than 20% of the lot; the code itself does the math for the standard lot, putting the ceiling at 17,424 square feet for a 2-acre parcel. 32(C)(3) restricts nonresidential accessory structures, such as detached garages, barns and storage buildings, to no more than 10% of the total lot area. Both limits are measured against the same lot area, so a homeowner building a large accessory building has to leave room for the primary residence to still fit under the overall 20% ceiling.
The Building Official reviews site plans against these coverage limits before issuing a building permit, and the standards apply uniformly to every lot in the SF district regardless of when the parcel was platted.
Violations & Fines
Building beyond the coverage limits, or without an approved plan showing compliance, is a misdemeanor under § 156.99(B)(1), punishable by a fine of up to $2,000 per offense, with each day the violation continues counted as a separate offense.
