  • Attached or detached deck less than thirty inches high needs a building permit and zoning permit.

Step 5: Inspections & Final Approval

Once work begins, you must schedule inspections (often you can do this through your contractor). 

  • Footing Inspection – Scheduled before concrete is poured, this inspection ensures your deck's footings are deep enough (typically 36 inches), properly spaced, and set on solid ground for a safe and stable foundation.
  • Framing Inspection – This inspection is conducted after the frame is built but before decking is installed, ensuring that joists, ledger boards, and hardware are correctly installed and meet code requirements for strength and safety.
  • Final Inspection – Once everything is complete, the inspector checks railings, stairs, flashing, and the overall construction to confirm that your deck is safe and up to code, then issues your Certificate of Use.

Local Zoning, Design & Code Requirements

Here’s where you’ll thank us for being detail-obsessed. Considering the following details before you begin your project will pay off in the long run. NOT thinking about them may result in some major headaches and delays. 

Setbacks & Lot Placement

Setback rules can vary depending on the lot size and location. Most residential decks must remain: 

  • 30–40 ft from road rights-of-way
  • 10 ft from property lines
  • At least 10 ft from septic tanks or drainage fields

Refer to Section 320-75 of the Zoning Code for specifics. 

Deck Height & Guardrails

  • Decks 30 inches or higher require railings.
  • Railings must be at least 36 inches tall and able to resist 200 pounds of outward force, per UCC safety standards.

Approved Materials

  • Use pressure-treated lumber, cedar, composite decking, or other code-approved materials.
  • Ledger boards must be properly flashed with corrosion-resistant materials to prevent water damage.
  • Use hot-dipped galvanized or stainless steel fasteners—essential for preventing rot and rust in Pennsylvania’s seasonal climate.

Structural Requirements

  • Joist spacing: typically 16″ on center, unless using upgraded composite boards.
  • Posts must be anchored to concrete footings at least 36 inches deep to reach below the frost line.
  • Use approved hardware connectors (like Simpson Strong-Tie) for beams, joists, and hangers.
Posts must be anchored to concrete footings at least 36 inches deep to reach below the frost line.

Stormwater Considerations

If your deck has an impervious surface (any surface that prevents water from seeping into the ground), you’ll need to:

This is to ensure that the impervious surface of your deck doesn’t cause runoff that results in flooding, erosion, or water pollution.

Inspections: What to Expect

Once your permit is approved, you’re still not quite done. Conestoga Township requires multiple inspections during the construction process:

  1. Footing Inspection: Before concrete is poured—checks for frost depth and placement.
  2. Framing Inspection: After ledger and joists are installed, checks structural elements and fastening.
  3. Final Inspection: Once railings, stairs, and all details are finished. Ensures your deck is safe and ready to use.  

Failed inspections may require a re-inspection fee, so it’s worth getting everything right the first time.

What Happens If You Build Without a Permit?

Thinking of building without a permit? We don’t recommend that. That is where things get messy—and expensive:

  • Double fees: Starting work without a permit may lead to double charges on your application (Fee Schedule).
  • Stop Work Orders: You could be legally forced to pause all construction.
  • Fines & Demolition: In extreme cases, decks may need to be altered or removed entirely.
  • Resale Issues: When selling, unpermitted decks can delay closings or reduce the value of your home.
