Vestavia Hills, AL Building Setbacks & Zoning: Lot Coverage Limits (2026)

2 govern every R-1 lot, and that table lists a Max. Building Area figure expressed as a percent of lot, set at 30 percent for R-1. That cap sits alongside a 20,000 square foot minimum lot area and a 115 foot minimum lot width, so a typical R-1 lot at the minimum size can carry roughly 6,000 square feet of building footprint before it trips the coverage limit. The same 30 percent figure recurs in the R-2 and R-3 tables that follow in Article 5, even though those districts allow smaller minimum lots (15,000 and smaller), so the percentage ceiling, not a flat square footage, is what constrains building footprint district by district.

2(1) reinforces the intent behind the cap by limiting each separately-owned lot of record to one main structure and its accessory buildings, which keeps a property owner from spreading multiple structures across a lot to approach the coverage ceiling piecemeal. 3 separately limits any accessory building to one story or 16 feet, so an addition, garage, or accessory dwelling has to be checked against both the accessory height rule and the parent lot's 30 percent building-area ceiling before a building permit can issue.
