Navigating Deck Permits in Derry Township, PA

TL;DR — Deck Permits in Derry Township, PA

  • You need two permits: For almost any deck project, you will need both a Zoning Permit from Derry Township and a UCC Building Permit managed by the Township's third-party agency, Bureau Veritas.
  • The 30-inch rule: A full building permit is required if the walking surface is over 30 inches above grade, but all decks require a zoning review.
  • The process involves two offices: You’ll submit plans to the Township office for zoning approval and apply to Bureau Veritas for the structural permit.
  • Specific codes are mandatory: Derry Township enforces the PA Uniform Construction Code (UCC), which includes strict rules for frost-depth footings, corrosion-resistant fasteners, ledger board connections, and railing height/spacing.
  • Don’t skip the permit: Building without one can lead to fines and expensive hourly penalty fees if the Township catches the unpermitted work.

Do You Need a Permit to Build a Deck in Derry Township?

The short answer is: Yes, you will almost certainly need two separate permits.

Derry Township, like most municipalities in Pennsylvania, operates under the Uniform Construction Code (UCC) and portions of the International Residential Code (IRC), which requires strict oversight of new construction to ensure public safety.

Here is the key distinction for your project:

  1. Zoning Permit: Required for the erection, construction, improvement, or alteration of any structure. This permit primarily deals with the placement of your deck on your property, ensuring it respects setbacks and property lines.
  • UCC Building Permit: This is the structural permit. It is required if the walking surface of your deck is more than 30 inches above the adjacent finished grade. Even if your deck is lower than 30 inches, we always recommend contacting the Township, as their accessory structure rules often still require a UCC check, or a formal statement of exemption.

You must obtain both the Zoning Permit and the Building Permit before you start construction.

Navigating the Deck Permit Application Process

Derry Township utilizes a third-party agency, Bureau Veritas North America (BVNA), to handle the Uniform Construction Code (UCC) plan review and inspections. This means your application journey involves two main steps:

Step 1: Gather Your Documents

This is where careful planning becomes important. You will need to prepare two sets of documents for submission:

  • Completed Application: You need to complete the UCC Building Permit Application.
  • Construction Drawings: Two (2) copies of complete plans and specifications are required. For a deck, this must clearly show framing details, lumber type/species, spacing, spans, railing details, and how the deck attaches to the house.
  • Site Plan (Survey): This drawing of your property shows the exact location and size of the proposed deck, along with the dimensions of all property lines (setbacks). This can sometimes be hand-drawn, but it must be to scale.
  • Workers Compensation Waiver/Certificate: Required if you are acting as the builder or hiring a contractor.

Step 2: Submission and Review

  1. Zoning Review: First, you typically submit your application and site plan to the Derry Township Office. They will review the placement of your deck against local zoning rules and issue a Zoning Permit.
  2. UCC Review & Permit Issuance: Once zoning is approved, the documents are sent to the third-party agency, Bureau Veritas. They review the structural plans against the PA UCC.
  • Timeline: For residential applications, the Township aims to process permits within 15 working days of receiving a complete application. Incomplete applications will be rejected.
  • Cost: The fee for your deck permit is split between the Township (for Zoning) and Bureau Veritas (for the UCC permit/plan review/inspections).
    • Zoning Fee: Approximately $50.00.
    • UCC Building Permit Fee (Deck/Alterations): This fee is based on the estimated value of the construction. As of their current fee schedule, the rate is often calculated as: $77.00 for the first $1,000.00 of work + $12.00 per each additional $1,000.00 of work thereafter, with a minimum fee of $200.00.

Specific Zoning and Code Requirements in Derry Township

Here’s where it gets tricky—but don’t worry! These are the specific, structural details that ensure your deck is safe and passes inspection. Derry Township enforces codes largely based on the International Residential Code (IRC) via the PA UCC.

Zoning & Setbacks

Decks are considered accessory structures and must adhere to the setbacks for your zoning district. Since zoning districts vary, you must confirm yours, but a common rule for accessory structures in Derry Township’s residential areas is:

  • Front Yard: Decks and accessory uses are generally not permitted in the principal front yard setback.
  • Side Yards: Minimum 10 feet from the property line.
  • Rear Yard: Minimum 5 feet from the property line.

Caption: Decks are considered accessory structures and must follow zoning setbacks, which in Derry Township residential areas generally prohibit decks in the front yard and require at least 10 feet from side property lines and 5 feet from the rear property line.

Here’s what that means for you: You must measure accurately from your property markers to the closest point of your proposed deck. If you are close to a property line, always call the Township Zoning Officer to confirm.

Materials and Structural Integrity

The materials and connections must meet high standards for safety and resistance to weather.

  • Footings (Foundation):
    • Footings must extend below the established frost line in Pennsylvania, which is typically a minimum of 36 inches deep to prevent shifting during freeze/thaw cycles.
    • Footings must be concrete and properly sized based on the deck’s load and soil-bearing capacity (usually rated for 40 pounds per square foot live load).
  • Lumber & Treatment: All wood used for structural components (posts, beams, joists) must be pressure-treated lumber (Southern Pine, grade #2 or better) to resist rot and insects.
  • Fasteners and Hardware (The Specifics!): This is a key failure point for many DIY jobs, so pay close attention.
    • Corrosion Resistance: All connectors, fasteners, bolts, and nails must be corrosion-resistant. This means they must be hot-dipped galvanized (meeting ASTM A 153) or stainless steel. Aluminum or improperly coated fasteners will fail inspection.
    • Nails: Any nails used must be threaded to prevent them from popping out as the wood expands and contracts.
  • Ledger Board Connection: If your deck is attached directly to your home's rim joist (the ledger board), it must be securely fastened with lag screws or through-bolts, not just nails. Proper flashing is mandatory above and behind the ledger board to prevent water from penetrating your home's structure.
  • Lateral Load Connectors: The deck must be positively anchored to the house using structural tie-down or hold-down devices (known as lateral load connectors) to resist lateral movement and prevent the deck from pulling away from the dwelling in high winds or high traffic.

Railings (Guardrails) and Stairs

  • Guardrails: Required if the deck surface is 30 inches or more above the adjacent grade.

  • Height: The top rail must be at least 36 inches high, measured from the deck surface.
  • Baluster Spacing: Balusters (vertical pickets) must be spaced so that no opening will allow a 4-inch sphere to pass through. This rule applies to the space between the deck surface and the bottom rail as well.
  • Stairs:
    • Maximum riser height is 7.75 inches.
    • Minimum tread depth is 10 inches.
    • Handrails are required for any stair flight with more than four risers.

Inspection Requirements

The permit process isn't done until you've passed the final inspection! Inspections ensure that the structure you built matches the approved plans and meets code at critical stages.

For a new deck in Derry Township, you will typically need to schedule the following inspections through Bureau Veritas (717-242-0992):

  1. Footing Inspection: This must be done after the holes are dug to the proper depth (36 inches) and diameter, but before any concrete is poured. The inspector verifies depth and placement.
  2. Framing Inspection: This takes place after all structural components are complete (posts, beams, joists, ledger board connections, lateral connectors) but before any decking, railings, or stairs are installed. The inspector confirms beam/joist sizing and hardware.
  3. Final Inspection: This is done when the deck is 100% complete, including decking, railings, steps, and handrails. They check the railing height, baluster spacing, and overall compliance.

The Consequences of Building Without a Permit

We understand the temptation to skip the paperwork, but the Township of Derry and Bureau Veritas are strict about enforcement. Per the Official BVNA Fee Schedule and Township Code:

  • The Hourly Penalty: If you are caught building (or have already finished) without a permit, you aren't just hit with a fine. BVNA reserves the right to charge a $77.00 per hour enforcement fee to process your late application.
  • Daily Fines: Each day your deck remains unpermitted can be considered a separate violation, with fines reaching up to $1,000 per day plus legal costs.
  • The "Uninsurable" Deck: Building without a permit is considered "negligent" by most insurance carriers. If an accident happens, your policy may not cover the liability, leaving your family and investment at risk.
  • Mandatory Demolition: In extreme cases where a deck violates setbacks or structural codes, the Township has the legal authority to declare it a Public Nuisance and require its full removal at the owner's expense.

It’s truly not worth the risk to your family or your investment!
