Still unanswered

We looked and could not find an official answer yet. Silence is not permission; ask Dallas or Polk County directly.

• Minimum dwelling size — Single-family residential districts inside Dallas city limits.
• Minimum lot size — Single-family residential districts inside Dallas city limits.
• Setbacks — Single-family residential districts inside Dallas city limits.
• Lot coverage — Single-family residential districts inside Dallas city limits.
• Building height — Single-family residential districts inside Dallas 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.
