Do You Need Permits for Egress Windows or Bilco Door Work This Winter?

A New Year project that boosts safety is always a smart move—especially in the basement. If you’re planning egress window installation, a Bilco door replacement, or a PermEntry stairway in January, you’re probably wondering about permits and inspections. The good news for homeowners in Spring City and across Berks, Bucks, Chester, Delaware, Lancaster, Lehigh, Montgomery, and Northampton counties: winter often means shorter municipal queues and quicker approvals, provided your application is clear and code-ready.

People Also Ask: Do I need a permit for an egress window or Bilco door?

In most Pennsylvania municipalities, yes. A building permit is typically required when:

You cut a new opening in a foundation wall for an egress window

You enlarge a window to meet egress size requirements

You install a new egress window well or deepen/alter an existing well

You add a PermEntry precast stairway and bulkhead

You modify structure, headers, or lintels, or change drainage around the foundation A straightforward, like-for-like Bilco door replacement may still require a permit if framing, stairs, or openings are altered. Township code cycles and processes vary, and Egress Systems, Inc. confirms requirements before work begins.

What inspectors look for on egress and bulkhead projects

Inspections focus on life safety, structure, and weather protection. Expect verification of:

Net clear opening and sill height that meet IRC-based egress window standards

Operability from the inside without keys, tools, or special knowledge

Window well size, required ladder/steps if depth exceeds 44 inches, and cover operability

Drainage: gravel base, drain tie-in to footing drain or sump to manage snowmelt

Flashing, sealing, and water-resistive barriers at the window-to-foundation interface

For PermEntry/Bilco: stair rise/run, headroom, handrails/guards, anchorage, and weather seals

Final grading and slope that move water away from the well and bulkhead

Winter timelines, fees, and inspection cadence

January can be a strategic time to submit. Many townships process residential permits faster in winter, and inspection schedules are often more flexible. Most single egress window projects receive:

One permit review (with drawings and product cut sheets)

A rough/open-excavation check as needed

A final inspection after installation and weather sealing Permit fees vary by municipality and scope; we outline expected costs in your proposal and build them into your project plan so there are no surprises.

Who pulls the permit—and what paperwork is needed?

Egress Systems, Inc. typically pulls permits on behalf of homeowners and coordinates inspections. Submittals often include a simple site plan, a foundation wall detail, and manufacturer specifications for the products we install—Wellcraft or Rockwell wells, Jeld-Wen egress windows, and Bilco doors or PermEntry assemblies. Before excavation, we also coordinate PA One Call (811) utility markings to keep the site safe and compliant.

Checklist to speed approval in southeastern Pennsylvania

Define the room’s intended use (sleeping, rec space) to size the opening properly

Provide clear drawings showing header sizing, sill height, and well dimensions

Include product cut sheets for windows, wells, covers, and bulkhead doors

Verify drainage strategy and downspout routing on your site plan

Confirm HOA approvals where applicable before submitting

Allow access windows for inspections and weather, especially around freeze-thaw cycles

When is a permit not required?

Minor maintenance—like replacing a deteriorated well cover with a comparable, operable model—may not trigger a building permit. However, anything that affects structure, egress sizing, or drainage typically does. Because rules vary, we always check your township’s requirements and advise the best path forward.

Why winter is a smart season for code-compliant upgrades

Freeze-thaw cycles in southeastern Pennsylvania demand precise drainage and sealing. Our crews set wells on washed gravel bases, tie drains where appropriate, use cold-rated sealants, and verify operability in cold conditions. For bulkhead doors, we specify weatherstripping, anti-lift hardware, and reinforced frames to reduce drafts and increase security—details that help your project pass inspection and perform through winter.
