Full Breakdown
Setbacks (required yards) are a core municipal zoning power in Pennsylvania. Section 603 of the MPC lets municipalities regulate the areas and dimensions of land to be occupied and the yards and open spaces to be left unoccupied. Chester County's Planning Commission advises but does not set setbacks. Each district in your municipality's zoning ordinance lists minimum front, side and rear yards, which vary by lot size and use. To find your numbers, look up your parcel's zoning district on your township's ordinance or ask the zoning officer before designing an addition, deck or new structure.
Violations & Fines
Building within a required yard without a variance can result in a zoning citation, fines, and an order to remove the encroaching structure; relief requires a Zoning Hearing Board variance.
