Setback (Building Setback)
The minimum distance a building must be from a property line, road, easement, or other boundary as required by local zoning ordinances. Decks, porches, and outbuildings have their own setback requirements.
In Detail
Typical residential setbacks: front 25–35 feet, side 5–10 feet, rear 20–30 feet — but these vary dramatically by municipality and zoning district. Detached structures (sheds, garages) often have reduced setbacks. Decks may or may not be subject to setback requirements depending on height and local rules. Always check the property survey and local zoning before planning any structure. Setback variances require a formal application, public hearing, and board approval.
