Every Boston electoral ward has a different ZBA track record. Ward 4 approves at roughly 95%, among the highest in the city, while Ward 7 sits near 81%, among the toughest. These differences reflect zoning patterns, development pressure, and neighborhood dynamics specific to each ward.

Ward-level rates are useful context but not a substitute for a parcel-specific read — two properties in the same ward can face very different odds depending on zoning district, lot size, and abutters. Verdwise reports both.
