How long does an ADU basement conversion take in Roswell in 2026?

Construction time for a basement ADU conversion in Roswell depends on the scope of work, contractor scheduling, and how many inspections the project needs for egress, electrical and plumbing changes, none of which follows a fixed schedule from project to project. A conversion that only needs cosmetic updates moves faster than one requiring a new egress window or full utility separation. A licensed contractor familiar with Roswell and Fulton County permitting can give a realistic schedule once plans are drawn.
