Alameda County Code §17.52.430 limits residential fences in Castro Valley to 4 feet in the required front yard, 6 feet in side and rear yards, and 2 feet within 30 feet of a street intersection (visibility triangle).
Section 17.52.430 of Title 17 (Zoning) sets fence heights for unincorporated Alameda County: within the required front yard, fences/walls/hedges shall not exceed 4 feet; within the required interior side yard, no more than 6 feet; within the required rear yard, no more than 6 feet; outside required yards, no more than 6 feet. §17.52.440 provides discretionary exceptions up to 12 feet via a conditional use or variance approval. §17.52.450 measures height upward from natural ground level. Castro Valley's hillside Chapter 17.51 provisions can layer additional view/scenic standards.
Building Department can require an over-height fence to be cut down or removed if no variance was obtained; failure becomes a Ch. 6.65 nuisance. Construction without a permit (fences over 6 ft typically need a building permit) carries a doubled-fee penalty.
