Pomona, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Sec. A, Building Height, defines height as the vertical dimension of a building measured from average grade in feet and stories, adopted to provide adequate light, air and safety and to protect neighborhood character. It applies to all lots: no building, portion of a building, or structure may exceed the maximum height in feet or stories allowed in its zoning district, except as listed in Sec. 5. Height in feet is measured from average grade to the mid-point of the roof for roofs pitched greater than 4:12, to the top of the roof deck for roofs pitched 4:12 or less, and to the topmost point for all other structures.

5 feet, or if dormers do not exceed 50% of the building's front, rear or side length. Average grade is calculated by averaging the highest and lowest sidewalk elevation along the primary street-facing facade, or within 5 feet of that facade where the sidewalk sits farther away; large or sloped sites may calculate average grade separately for each stepped building module. Top plate height, measured from average grade to the building's top plate, cannot exceed the district's maximum height in feet. Sec. 5 allows specific rooftop and architectural elements, such as roof-mounted mechanical equipment, architectural elements, vertical circulation, safety barriers, unenclosed structures, flatwork and vegetation, to encroach above the height limit within defined setbacks from the roof edge that scale with the building's Form Module height tier, while signs face no height-limit encroachment cap under Sec. 630.
