• Building code adopted — Construction inside Watertown city limits.
• Minimum dwelling size — Residential zoning districts inside Watertown city limits.
• Minimum lot size — Residential zoning districts inside Watertown city limits.

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
