Full Breakdown
Under Waltham Zoning Ordinance, fences in residential front yards cannot exceed 4 feet in height, while side and rear yard fences can reach 6 feet without a special permit. Corner lots have additional sight-triangle rules at intersections. Fences taller than 6 feet require a building permit and may need Zoning Board approval. Decorative arbors and pergolas attached to fences may be exempt if spaced properly. Brandeis and Bentley campus edges often exceed these limits through institutional exemptions. Commercial and industrial zones along the 128 corridor permit taller security fencing up to 8 feet with permits.
