Harrisburg Zoning Overview

Harrisburg is the capital city of Pennsylvania, located along the Susquehanna River in Dauphin County. With a population of approximately 50,099, the city serves as the center of state government and a regional hub for south-central Pennsylvania. Harrisburg's economy is anchored by state government, healthcare (Penn State Health), and logistics due to its central location along major transportation corridors including Interstate 81 and the Pennsylvania Turnpike.

The city's zoning is managed by the Department of Building and Housing Development. Harrisburg's land use reflects its role as a state capital, with a dense downtown core of government buildings, a mix of rowhouse and detached residential neighborhoods, commercial corridors, and industrial areas. The city has invested in revitalization efforts including its riverfront park system and Midtown district.

Key Zoning Districts

Harrisburg'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 relatively small minimum lot sizes reflect Harrisburg's dense urban grid of rowhouses and twin homes. The CBD (Central Business District) covers the downtown government and commercial core. Commercial districts C-1 and C-2 serve neighborhood and general commercial needs, and the I (Industrial) district accommodates manufacturing and warehousing.

ADU Regulations

Harrisburg does not currently have confirmed ADU (Accessory Dwelling Unit) provisions. Pennsylvania has no statewide ADU mandate. Property owners interested in adding a secondary dwelling unit should contact the Department of Building and Housing Development to discuss available options under the city's zoning ordinance.

Development Process

The Department of Building and Housing 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. Harrisburg has several historic districts that may require additional review by the Historical Architectural Review Board (HARB). All construction must comply with the PA Uniform Construction Code (UCC).
