Montgomery County sets no lot-coverage limit. Maximum building and impervious-surface coverage are set by each borough and township zoning code under the PA Municipalities Planning Code, varying by zoning district.
Maximum lot coverage, the share of your parcel that buildings and paving may cover, is a municipal standard, not a county one. Pennsylvania counties do not zone, but the PA Municipalities Planning Code authorizes each municipality to regulate the areas and dimensions of land to be occupied by uses and structures and the intensity of use. Your borough or township zoning code therefore sets both building coverage and total impervious coverage percentages by district; denser districts allow higher coverage than large-lot residential zones. These limits, often paired with stormwater management rules, cap how much you can build or pave. Check your parcel's zoning district in your municipality's code for the exact maximum coverage.
Exceeding the district's coverage or impervious limit without relief is a municipal zoning violation, enforced with permit denial, a stop-work order, daily fines, and possible required removal of excess paving or structures.
