Planning a construction or renovation project in Pennsylvania often involves more than hiring a contractor and starting the work. Depending on the type and location of the project, you may need building permits, engineering drawings, structural calculations, and other documents before construction can begin.
NEC Solutions LLC provides structural and civil engineering services for residential, commercial, and industrial projects throughout Pennsylvania, New York, Delaware, and Texas — working with homeowners, contractors, architects, developers, and property managers to prepare professional documents for permit submission.
What Is a Building Permit?
A building permit is an approval from the appropriate local authority that allows certain construction or modification work to proceed. Requirements depend on the type of project, the property location, and the local municipality. Projects that often require permits include new home construction, additions, structural modifications, load-bearing wall removal, retaining walls, tenant improvements, deck construction, and solar installations.
When Do You Need an Engineer for a Building Permit?
Not every building permit requires the same documentation. Some projects require professionally prepared structural drawings, calculations, or a PE-stamped drawing package before a municipality can review or approve the project — which is why it's useful to involve an engineer early in the planning process. An engineer can review your project and help identify what documents may be required.
PE-Stamped Drawings for Pennsylvania Building Permits
A Professional Engineer's stamp and signature certify that the engineer has reviewed and taken professional responsibility for the engineering work. NEC Solutions provides PE-stamped drawings and engineering documents for qualifying projects, and currently holds an active Pennsylvania PE license along with licenses in New York, Delaware, and Texas.
Common Pennsylvania Projects That Need Engineering
Load-bearing wall removal — a structural engineer determines whether a wall is load-bearing and designs the required beam or post support. See our Load Bearing Wall Removal services.
Home additions — a new room, second-story addition, or garage can change the structural loads on an existing building, and engineering drawings are often required as part of the permit process.
Retaining walls — depending on height, location, and local requirements, retaining walls can require engineering. See our Retaining Wall Design page.
Solar installations — installing solar panels adds load to a roof, and a structural engineer may need to evaluate the roof and prepare documentation for the permit process. See Solar Structural Engineering.
Commercial construction & renovations — office renovations, retail buildouts, warehouse projects, tenant improvements, and change-of-occupancy projects can all involve more detailed engineering and permitting requirements.
What Information Does an Engineer Need?
You don't necessarily need a complete permit package ready before contacting an engineer. For an initial project review, we typically ask for the property address, project location, a description of the proposed work, existing architectural drawings (if available), site photographs, and any building department requirements already provided.
Can NEC Solutions Help With Permit Revisions?
Yes. If a building department reviews our engineering drawings and issues reasonable plan-review comments requiring revisions, we address those comments promptly at no additional charge — engineering support doesn't end when the drawings are submitted.
How the Building Permit Engineering Process Works
- Submit your project information — property address, project description, photos, and any building department correspondence
- Project review — our team reviews the information and determines what engineering services are required
- Receive a quote — an itemized project quote, generally within 24 business hours
- Engineering and drawings — calculations, drawings, and details are prepared for your project
- PE review and stamp — completed documents are reviewed, signed, and PE-stamped
- Permit submission — the completed package is ready for your local building department
Full permit packages generally take around 7–10 business days, although more complex projects can require additional time — providing complete project information up front helps avoid unnecessary delays.
