Site plans and permit drawings in Delaware County, PA.

Permitting in Delaware County, Pennsylvania

Pennsylvania permitting in Delaware County is municipality-specific. The city, borough or township where the property is located controls zoning and usually administers the UCC itself or through a certified third-party agency; county government is not a universal building-permit office.

Dense suburban and urban development makes zoning district, lot coverage, parking, stormwater and existing-condition documentation especially important. Historic districts, narrow lots and older buildings can add review layers in some municipalities.

For a property near Media or elsewhere in the county, the same project type can follow a different zoning ordinance, setback table, floodplain procedure or submission checklist. We verify jurisdiction before drafting rather than assuming countywide rules.

What we verify before drafting

• Municipality and UCC agency: the city, borough or township that controls zoning and the office or certified agency handling building-code review.
• Zoning district: setbacks, lot coverage, height, accessory-structure limits, parking and use restrictions.
• Survey and site data: property lines, easements, existing structures, proposed work and dimensions.
• Floodplain and drainage: FEMA/PEMA mapping, local floodplain ordinance, stormwater and drainage where applicable.
• Road access: municipal road versus state highway and possible PennDOT Highway Occupancy Permit coordination.
• Sewage: public sewer or on-lot sewage requirements under the municipality’s Act 537 program.

Permit drawing services in Delaware County

We prepare site plans, plot plans, architectural permit drawings, structural plans and calculations, MEP plans, grading and drainage plans, as-built drawings and permit-correction packages. The package is based on the project and reviewing municipality, not a generic county template.

Common work includes additions, garages, decks, porches, patio covers, sheds, pools, fences, retaining walls, remodels, new homes, metal buildings, accessory dwellings where allowed and commercial tenant improvements. Some projects need only a site plan; others need coordinated architectural, structural and MEP sheets.

State-highway, floodplain and sewage checks

A new or altered driveway on a state highway can require a PennDOT Highway Occupancy Permit. Sites near rivers, creeks or mapped floodplains may need local floodplain approval, and stream or wetland impacts can trigger Pennsylvania DEP or federal review. Where public sewer is unavailable, local agencies and Sewage Enforcement Officers administer on-lot sewage permitting and Act 537 planning.
