In Howard County's common R-20 residential district, principal structures must sit at least 20 feet from the front lot line, 10 feet from side lines, and 30 feet from the rear. Larger setbacks apply along arterial or collector roads.
Howard County zones all unincorporated land, so district bulk tables set building setbacks countywide. In the R-20 (Residential: Single) District, minimum setbacks from lot lines are 20 feet in front (30 feet for pipestem lots facing the project boundary), 10 feet on each side, 30 feet at the rear for a principal structure, and 10 feet for accessory structures. Setbacks measured from an arterial or collector public street right-of-way rise to 40 or 50 feet, and from other public streets 30 or 50 feet. Other districts (R-12, R-SC, RC, RR) have their own tables in the Zoning Regulations.
Structures built inside a required setback violate the Zoning Regulations; DILP can deny permits, issue violations, or require alteration. A variance from the Hearing Examiner is needed to encroach.
