Full Breakdown
16, the county's highest-density residential zone, allows 60 feet. Height is measured under the Section 101 definition of Building Height as the vertical distance from the highest point of the structure down to the horizontal projection of the closest point at exterior grade, and where fill has artificially raised the grade, the measurement instead runs from the natural or surrounding finished grade. 16 Zone is capped at 30 feet if the lot exceeds four acres, the property boundary lies within one mile of a public school operating above 105 percent of its State-rated capacity, and the site sits in or within 1,000 feet of a Tier II growth area, a restriction added by Bill No.
54-2019 to slow density-driven crowding near strained schools. The Department of Permits, Approvals and Inspections checks proposed height against these tables when it reviews a building permit application, and Section 504 allows the County to adopt higher standards for greater building heights only through the Comprehensive Manual of Development Policies process, not by administrative waiver.
Violations & Fines
Building without a permit or constructing above the applicable height limit is enforced as a zoning violation under BCZR Section 503.1, which makes any violation of the zoning regulations a misdemeanor punishable by a fine of up to $100.00, imprisonment of up to 30 days, or both. Each day the violation continues counts as a separate offense, so an unpermitted structure left standing above the limit can generate a new charge daily until it is brought into compliance or removed.
