Gilbert's Building Setbacks & Zoning: The Rules That Matter

Every city handles building setbacks & zoning a little differently. In Gilbert, Arizona, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Lot Coverage Limits

Gilbert's Land Development Code limits lot coverage by zoning district. Residential districts typically limit building coverage to 40-50%. Impervious surface limits are important due to stormwater retention requirements in the desert environment. Pool decks, patios, and driveways count toward impervious surface calculations. Desert landscaping helps minimize impervious coverage.

Exceeding lot coverage: correction required. May need to remove impervious surface. Fines $200 to $1,000.

Setback Rules

Gilbert's Land Development Code establishes minimum setback requirements by zoning district. Residential districts typically require front setbacks of 20-25 feet, side setbacks of 5-10 feet, and rear setbacks of 15-20 feet. Any building 200 square feet or larger requires a building permit. HOA CC&Rs in many Gilbert subdivisions may impose additional setback requirements beyond the town code.

Structure Height Limits

Gilbert's Land Development Code sets maximum building heights by zoning district. Single-family residential districts generally limit structures to 30 feet or 2 stories. The Heritage District and commercial areas may allow greater heights. Building height is measured from finished grade to the highest point of the roof. HOAs may impose additional restrictions.
