Still unanswered

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

• Owner-builder exemption — Owner-built residences inside Athens city limits.
• Certificate of occupancy — New or altered buildings inside Athens city limits.
• Minimum dwelling size — Dwellings inside Athens city limits.
• Minimum lot size — Residential lots inside Athens city limits.
• Lot coverage — Lots inside Athens 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.
