Lancaster Zoning Overview

Lancaster is a city in Lancaster County, Pennsylvania, and the county seat of one of the most productive agricultural counties in the United States. With a population of approximately 63,069, Lancaster is the economic and cultural hub of the Lancaster County region. The city has a rich history dating to 1730 and served briefly as the capital of the United States in 1777. Lancaster has undergone a significant urban renaissance, with its downtown and surrounding neighborhoods attracting new residents, businesses, restaurants, and cultural institutions.

The city's zoning is managed by the Department of Community Planning and Economic Development. Lancaster's land use reflects its compact urban form, with a walkable downtown centered on Penn Square, dense residential neighborhoods of rowhouses and detached homes, commercial corridors, and mixed-use areas. The city has been recognized nationally for its urban planning and revitalization efforts.

Key Zoning Districts

Lancaster's zoning code includes residential districts R-1 (Low Density, 5,000 sq ft minimum lots), R-2 (Medium Density, 4,000 sq ft minimum lots), and R-3 (Multi-Family). The MU (Mixed Use) district supports Lancaster's emphasis on walkable, mixed-use development. Commercial districts include C-1 (Neighborhood Commercial) and C-2 (General Commercial). The I (Industrial) district accommodates manufacturing and warehousing.

ADU Regulations

Lancaster allows accessory dwelling units (ADUs). Pennsylvania has no statewide ADU mandate, so Lancaster's ADU provisions are entirely local. Property owners interested in building an ADU should contact the Department of Community Planning and Economic Development for specific requirements regarding size, setbacks, parking, and other standards.

Development Process

The Department of Community Planning and Economic Development processes development applications and building permits. The Zoning Hearing Board handles variances and special exceptions. The Planning Commission reviews subdivisions and land development plans. Lancaster has a significant historic district with design review requirements administered by the Historical Commission and Historical Architectural Review Board (HARB). All construction must comply with the PA Uniform Construction Code (UCC).
