Alpharetta FAQ
Is there a statewide maximum building height in Georgia?
Yes, indirectly. The state-adopted International Building Code caps height by construction type and occupancy. Wood-frame residential is generally limited to about 60 feet.
Can a Georgia city allow taller buildings than the state code?
No. The State Minimum Standard Codes set ceilings cities cannot exceed without alternate engineering. Cities may, however, set lower height limits through zoning.
Roswell FAQ
Can I build a 3-story house in Roswell?
Generally yes if the overall height stays at or below 35 ft to mean roof level. Tall third stories with steep roof pitches sometimes hit the cap.
Why does Roswell have an angular-plane rule?
The 30-degree angular plane projected from a 35-ft reference height at the side and rear setback lines prevents very tall structures from looming over neighbors even when the footprint is in compliance.
