Still unanswered

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

• Owner-builder exemption — Owner-builder permit exemption inside Ames city limits
• Inspections — Building inspections for new homes inside Ames city limits
• Certificate of occupancy — Certificate of occupancy for new homes inside Ames 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.
