Still unanswered

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

• Building code adopted — Buildings inside Denison city limits.
• Certificate of occupancy — Building occupancy inside Denison city limits.
• Minimum dwelling size — Residential dwellings inside Denison 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.
