Delaware County Building Permit Guide (2026)
A Homeowner’s Guide to Remodeling Permits in Delaware County, PA
Planning a home renovation in Delaware County? One of the first questions many homeowners ask is: “Do I need a permit?” The answer depends on the type of project you’re planning—and understanding the permitting process before work begins can save you time, money, and unnecessary headaches.
At Cumming Construction, we’ve helped homeowners throughout Havertown, Springfield, Media, Newtown Square, Broomall, Upper Darby, Marple Township, and surrounding Delaware County communities successfully navigate home remodeling projects for more than 25 years. While every municipality has its own permitting requirements, this guide explains what homeowners should know before starting a renovation.
Whether you’re remodeling a kitchen, finishing a basement, building an addition, or replacing a deck, this resource will help you understand how building permits work in Delaware County.
Quick Answer: Do You Need a Permit?
For many home improvement projects, yes.
Generally speaking, permits are commonly required when work involves:
- Structural changes
- Electrical work
- Plumbing modifications
- HVAC installation
- New additions
- Deck construction
- Roof framing changes
- Finished basements
- Major bathroom remodels
- Major kitchen remodels
Smaller cosmetic updates like painting, flooring, or replacing cabinets in the same layout often do not require permits—but there are exceptions.
The best approach is to verify permit requirements with your local municipality before beginning work.
Why Building Permits Matter
Some homeowners view permits as an inconvenience, but they’re designed to protect both homeowners and future buyers.
Permits help ensure:
- Construction meets current building codes
- Electrical work is safe
- Plumbing systems function properly
- Structural changes are properly engineered
- Homeowners are protected during inspections
- Future home sales proceed without permit-related issues
Skipping required permits can lead to:
- Stop-work orders
- Costly corrections
- Difficulty selling your home
- Insurance complications
- Municipal fines
Obtaining permits upfront is almost always the smarter—and less expensive—choice.
Common Remodeling Projects That May Require Permits
Below are some of the most common home improvement projects homeowners ask us about.
Kitchen Remodeling
Many cosmetic kitchen updates can be completed without permits.
However, permits are often required when your project includes:
- Moving plumbing
- Relocating electrical outlets
- Installing new circuits
- Removing walls
- Structural modifications
- Gas line work
If you’re simply replacing cabinets in the same locations or installing new countertops, permit requirements may be different than a complete kitchen renovation.

Bathroom Remodeling
Bathroom remodel permits often depend on whether plumbing or electrical systems are being modified.
Projects that frequently require permits include:
- Relocating plumbing fixtures
- Installing new shower plumbing
- Electrical upgrades
- Ventilation changes
- Structural repairs
Simple fixture replacements may not require permits depending on local regulations.
Basement Finishing
Finished basements commonly require permits because they often involve:
- Framing
- Electrical work
- HVAC
- Insulation
- Egress requirements
- Smoke detectors
Basement permits help ensure finished spaces meet current safety codes.
Deck Construction
New decks almost always require permits.
Requirements may include:
- Footing inspections
- Structural framing inspections
- Guardrail compliance
- Stair requirements
Deck safety has become an increasing focus of local building departments.
Home Additions
Home additions are among the most heavily regulated residential projects.
Typical permits involve:
- Building
- Electrical
- Plumbing
- Mechanical
- Zoning approval
Multiple inspections typically occur throughout construction.
Roofing
Not every roofing project requires the same approvals.
While simple roof replacements may have different requirements than structural roof modifications, homeowners should always verify local regulations before beginning work.
Window & Door Replacement
Many homeowners are surprised to learn that replacing windows or exterior doors may require permits in some municipalities—particularly if the size of the opening is changing.
Delaware County Municipalities Have Different Requirements
One important thing to understand is that Delaware County does not issue one countywide building permit.
Instead, permits are generally administered by individual boroughs and townships or their designated third-party code officials.
Some of the communities we frequently work in include:
- Havertown (Haverford Township)
- Springfield Township
- Marple Township
- Upper Darby Township
- Media
- Newtown Township
- Radnor Township
- Ridley Township
- Nether Providence Township
- Middletown Township
- Aston Township
- Brookhaven
- Swarthmore
- Glenolden
- Prospect Park
Because permit procedures, fees, submission requirements, and inspection schedules can vary, it’s important to work with a contractor familiar with your municipality’s process.
What Does the Permit Process Usually Look Like?
Although each municipality is different, the process generally follows these steps:
1. Project Planning
Determine the scope of work.
This includes:
- Measurements
- Material selections
- Layout
- Budget
- Engineering (if needed)
2. Construction Drawings
Many permits require plans showing:
- Existing conditions
- Proposed changes
- Structural details
- Electrical layouts
- Plumbing modifications
3. Permit Application
Applications typically include:
- Permit forms
- Construction drawings
- Contractor information
- Estimated project cost
Some municipalities allow online submissions, while others require in-person applications.
4. Plan Review
The municipality or third-party code official reviews the plans to verify code compliance.
Review times vary depending on project complexity.
5. Permit Approval
Once approved, work can begin.
Most municipalities require the permit to remain visible at the job site during construction.
6. Inspections
Depending on the project, inspections may include:
- Footings
- Framing
- Electrical
- Plumbing
- Mechanical
- Insulation
- Final inspection
Inspections help verify work complies with applicable building codes.
How Long Does It Take to Get a Building Permit?
Permit timelines vary depending on:
- Municipality
- Project size
- Completeness of application
- Seasonal demand
- Engineering requirements
Smaller residential permits may be processed relatively quickly, while additions or structural renovations often take longer because additional reviews may be required.
Planning ahead helps avoid unnecessary project delays.
Can Homeowners Pull Their Own Permit?
In many municipalities, homeowners may be allowed to obtain permits for work performed on their own residence.
However, contractor-performed work is often handled through the licensed contractor, depending on local requirements.
Before deciding who should obtain the permit, it’s worth discussing the process with both your contractor and your local building department.
What Happens If You Remodel Without a Permit?
This is one of the most common questions we hear.
Potential consequences include:
- Stop-work orders
- Required demolition
- Additional permit fees
- Delayed home sales
- Failed inspections during resale
- Insurance claim complications
In many cases, obtaining permits before work begins is far easier than correcting permit issues later.
Tips for a Smooth Remodeling Project
Homeowners can make the permitting process much easier by following a few best practices:
Plan Early
Don’t wait until materials have been ordered to begin discussing permits.
Hire Experienced Contractors
Experienced remodeling contractors understand local permitting procedures and can help guide you through the process.
Avoid Unpermitted Work
Even if someone suggests “you don’t need a permit,” it’s always worth verifying with your municipality.
Budget for Permit Costs
Permit fees are typically a small percentage of the overall project and help protect your investment.
Keep Copies of Your Documentation
Maintain copies of permits, inspection reports, and approved plans for future reference.
