Pennsylvania has one of the most geographically diverse permit markets in the northeastern United States. From dense urban centers like Philadelphia and Pittsburgh to small townships with minimal permit infrastructure, requirements vary significantly across the state’s 67 counties and 2,560+ municipalities.
I’m Engineer Wasim of Site Plans Online USA. We serve Pennsylvania homeowners, contractors, and developers across the entire state. This guide explains what Pennsylvania building departments typically need.
Homeowners beginning the application process can first review how to get a site plan for a permit and understand the property information required before drafting begins.
Pennsylvania Building Code Structure
Pennsylvania operates under the Uniform Construction Code (UCC), administered by the Pennsylvania Department of Labor & Industry. Key aspects:
- Municipalities can opt in to enforce the UCC locally or have the state enforcer handle it
- Philadelphia has its own comprehensive building code system entirely separate from the UCC
- Pittsburgh follows Allegheny County with city-specific additions
- Some small townships still operate under pre-UCC local codes
- Pennsylvania has no single statewide digital permit portal; submission methods vary by municipality
What a Pennsylvania Permit Site Plan Requires
For most residential permits across Pennsylvania:
Universal Elements
- Property boundaries with dimensions
- Tax parcel number (Pennsylvania’s property identifier, visible on PA county tax assessment websites)
- Legal description matching assessment records
- Property address and adjacent street names
- North arrow
- Scale and graphic scale bar (1″=20′ standard)
- All existing structures with dimensions
- Proposed project labeled and dimensioned
- All setback dimensions from property lines
- Impervious surface calculation for most project types
- Easements if recorded on the property
- Title block with owner, preparer, APN, date, scale
For pools, fences, sheds, decks, additions, and other home projects, our residential site plan services provide scaled property drawings prepared according to the applicable municipal requirements.
Pennsylvania Residential Setbacks — General Standards
Pennsylvania setbacks are set at the township/borough level, not statewide. Typical residential standards across PA:
- Front setback: 25–30 ft (most municipalities)
- Rear setback: 15–25 ft
- Side setback: 5–10 ft
- Accessory structures (sheds, garages): typically 5–10 ft rear and side
- Pool to property lines: typically 5–10 ft, depending on municipality
Always verify your specific municipality. We research the applicable code for every order.
Why Municipal Requirements Must Be Verified
Because permit administration is handled locally, the first step is confirming the correct city, borough, township, or county department for the property. A mailing address alone may not identify the department responsible for reviewing the application.
Applicants should verify zoning, setbacks, impervious-surface limits, flood or historic overlays, accepted sheet sizes, required forms, and the submission method before drafting. This reduces the risk of preparing a plan for the wrong department or omitting information requested by the local checklist.
Our permit drafting services account for available parcel information, local zoning requirements, setbacks, property conditions, and submission standards before the drawing is finalized.
This verification helps ensure that residential, accessory-structure, pool, addition, and commercial applications are formatted for the municipality that will actually review them.
Major Pennsylvania Markets
Philadelphia
Philadelphia’s L&I (Department of Licenses and Inspections) handles all permits through the eCLIPSE portal.
- Plans must be uploaded as PDFs with specific file naming
- Philadelphia has strict documentation requirements compared to suburban PA
- FEMA flood zones: significant portions of Philadelphia are in AE flood zones along the Schuylkill and Delaware Rivers
Allegheny County / Pittsburgh
- City of Pittsburgh: Bureau of Building Inspection (separate from county)
- Allegheny County unincorporated: County Building Inspection
- Pittsburgh has many historic districts with additional overlay requirements
Philadelphia Suburbs (Chester, Montgomery, Bucks, Delaware Counties)
- These are PA’s fastest-growing residential permit markets
- Each of the 100+ municipalities in these counties has independent zoning codes
- Requirements vary township by township, and we research each individually
Central PA — York, Lancaster, Harrisburg Area
- Generally follows standard UCC requirements
- Lancaster County: particularly active residential construction market
- Many rural townships have minimal permit requirements
Lehigh Valley (Allentown, Bethlehem, Easton)
- Active residential and commercial market
- Two-county area (Lehigh and Northampton) with independent municipal codes
Pennsylvania Commercial Site Plans
For commercial permits in Pennsylvania:
- Parking layout with ADA spaces required
- PE stamp required for most commercial construction
- Drainage plan may require separate engineering
- Philadelphia: additional review for ADA compliance and historic properties
Projects involving parking, accessibility, fire access, utilities, drainage, and site-development calculations should use professionally prepared commercial site plans.
A licensed review may be required for commercial, structural, grading, or drainage work. Our PE stamp services support eligible projects that require signed and sealed drawings.
For straightforward residential projects that only require a clear property layout and zoning-compliance drawing, non-certified site plans may be accepted. Final acceptance depends on the project scope and the reviewing Pennsylvania municipality.
How We Prepare Pennsylvania Permit Site Plans
Before drafting begins, we review the property address, project type, available parcel records, assessment data, and municipal requirements. The drawing is then prepared to show existing conditions, proposed work, setbacks, easements, access, and relevant calculations.
The final plan should be checked against the local application checklist so the dimensions, labels, title block, and supporting documents remain consistent before submission.
Frequently Asked Questions (FAQs)
What does a Pennsylvania permit site plan include?
A Pennsylvania permit site plan normally includes property boundaries, parcel information, existing structures, proposed work, setbacks, easements, adjacent streets, a north arrow, drawing scale, and a title block. Some municipalities also request impervious-surface, drainage, or parking calculations.
Do site plan requirements vary across Pennsylvania?
Yes. Pennsylvania municipalities use different zoning codes, setbacks, forms, submission portals, and review procedures. Requirements in Philadelphia may differ from Pittsburgh, Lancaster, York, suburban townships, or rural boroughs, so the correct municipality must be confirmed before drafting.
Do I need a survey for a Pennsylvania site plan?
Not always. Many residential plans can be prepared using county assessment records, parcel maps, GIS data, and available property documents. A licensed survey may be required when boundaries are uncertain or the municipality specifically requests certified property information.
Does a Pennsylvania residential site plan need a PE stamp?
Most simple residential projects do not automatically require a PE stamp. Structural, commercial, drainage, grading, or engineered work may require licensed review. Learn when non-certified site plans may be suitable for permit submission.
What are typical residential setbacks in Pennsylvania?
Pennsylvania has no single statewide setback standard. Front, rear, side, pool, and accessory-structure setbacks are normally established by the local township, borough, or city. The property’s zoning district should always be verified before preparing or submitting the plan.
How are Philadelphia permit site plans submitted?
Philadelphia permits are generally handled through the Department of Licenses and Inspections and its eCLIPSE system. Applicants should confirm PDF formatting, file naming, required forms, and additional flood-zone, historic, zoning, accessibility, or project-specific documentation before submission.
What should a Pittsburgh site plan show?
A Pittsburgh site plan should clearly show property boundaries, existing buildings, proposed construction, setbacks, access, easements, and required calculations. Historic districts, steep sites, drainage concerns, or structural work may trigger additional city review or professional documentation.
What information is needed for a Pennsylvania commercial site plan?
Commercial site plans commonly show parking, ADA spaces, access points, fire lanes, drainage, utilities, landscaping, and building locations. Complex developments may also require coordinated engineering, architectural, stormwater, accessibility, or structural documents before the municipality accepts the application.
Why do Pennsylvania site plans receive corrections?
Common correction reasons include missing setbacks, incorrect parcel information, omitted structures, unclear scale, missing easements, incomplete impervious-surface calculations, or the wrong submission format. Local zoning rules and portal requirements should be checked before the drawing is finalized.
How do I start a Pennsylvania permit site plan?
Start by confirming the property’s municipality, zoning district, project type, and required documents. Then review how to get a site plan for a permit before collecting parcel records, measurements, photographs, and existing correction notices.
