ADU rules in Lawrenceville, GA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Lawrenceville does not broadly allow detached ADUs by right in single-family zones. Accessory apartments/in-law suites typically require Special Use Permit. Georgia has no statewide ADU mandate.
Lawrenceville UDO limits single-family residential zones to one principal dwelling unit. In-law suites inside the main home are generally allowed if they share utilities and do not create a separate dwelling unit under the building code. Detached ADUs over garages or in backyards typically require rezoning or Special Use Permit approval by City Council with public hearing. Townhome (R-TH) and multi-family zones may have different allowances.
Unpermitted second dwelling: stop-use and potentially removal. Renting out unpermitted ADU: Code Enforcement action.
