Full Breakdown

There is no countywide height cap in Montgomery County because Pennsylvania counties do not zone. Under the PA Municipalities Planning Code, each municipality may regulate the size, height and bulk of structures, so maximum building heights appear in your borough or township zoning code by district. Typical suburban residential districts cap principal buildings around 35 feet or two and a half stories, with lower limits for accessory structures like sheds and detached garages, but the exact figure is a municipal choice. Height is usually measured to the mean roof level or ridge as defined locally. Confirm the maximum height for your zoning district and structure type with your township zoning officer.

Violations & Fines

Exceeding the local height limit without a variance is a municipal zoning violation, enforced with a stop-work order, withheld occupancy approval, daily fines, and possible required alteration.
