Denver's Zoning Code limits lot coverage (the percentage of a lot covered by buildings and structures) based on zone district. Lot coverage limits help preserve open space, manage stormwater, and maintain neighborhood character. CPD reviews lot coverage during building permit review.
Typical lot coverage limits in Denver: Single Unit (SU) zones allow 37.5-50% lot coverage depending on the specific zone, Two Unit (TU) zones allow 37.5-50%, and multi-unit zones vary. Lot coverage is calculated as the total footprint of all buildings and covered structures (including garages, carports, and covered patios) divided by the total lot area. Uncovered decks, swimming pools, and pervious pavers may not count toward coverage depending on the zone district. The DZC's Form Standards chapter specifies coverage calculations for each building form. Accessory structure footprints count toward total lot coverage.
Exceeding lot coverage limits results in building permit denial. Unpermitted construction that pushes lot coverage over limits may require removal. Lot coverage violations discovered during permit applications for additions or renovations must be resolved before new permits are issued. Variances require Board of Adjustment approval.
