Inside the Athens city limits, you pull a permit before the first nail

Athens draws a clear line: a building permit is required for all new construction and most changes to existing structures, and you can't break ground or swing a hammer until the permit is actually issued. A weekend deck or a new commercial slab alike starts at the same place, the permit desk, not the lumber yard.

The city moved its whole permitting system online. Applications and inspection scheduling both run through MGOconnect (the My Government Online portal), so you set up an account, submit, and book inspections from your phone rather than standing in line. The Development Services office that backs it up sits at 501 US Hwy. 175 W in Athens, and there's a help line for the portal itself if it gets stubborn.

The part that catches newcomers is jurisdiction. This city process only applies inside the Athens limits. If your lot is out in the unincorporated county, common around Cedar Creek Reservoir or the rural roads between towns, the city has no say, and you'd deal with Henderson County's development and floodplain office instead. Knowing which side of the line you're on saves a wasted trip.
