The 17036 Regulatory Split

The 17036 ZIP code covers properties in Hummelstown Borough, Derry Township, and South Hanover Township. Your mailing address does not determine your permit authority. Your parcel does.

Setbacks, structural review triggers, and impervious coverage limits all change depending on which municipality governs the property.

We confirm the jurisdiction before the pergola footprint is designed. Applying Borough setback rules to a Derry Township property, or vice versa, is one of the more common ways pergola projects stall mid-review.

Hummelstown Borough Pergola Rules

Hummelstown Borough gives tighter lots more placement flexibility. Freestanding pergolas can use a 2-foot side setback and 3-foot rear setback under § 27-807, which lets homeowners place a structure closer to the usable edge of a compact backyard than many expect.

The Borough also caps total impervious lot coverage at 40% in Residential-Cluster overlays under § 27-808. A pergola’s patio base, concrete pad, or louvered roof can count toward that figure, so we calculate existing and proposed coverage before finalizing the layout.

Derry Township and Hershey-Area Pergola Rules

Derry Township and Hershey-area projects go through the local building code administration under Ordinance 114.

The exact setback and structural requirements depend on the zoning district, which we verify from the parcel data before any design work begins. We do not carry Borough setbacks over to Derry Township properties.

Freestanding vs. Attached: The Permit Difference

This choice affects the permit path more than any other design decision.

Freestanding Pergolas

A freestanding pergola stands on its own posts and footings, with no connection to the house's wall system.

It still needs proper placement within setbacks, frost-depth footings, and local zoning review, but it avoids the structural addition classification that comes with attaching to the home.

Freestanding designs often move through review faster.

Attached Pergolas

An attached pergola connects directly to the house. Under Pennsylvania's Uniform Construction Code, that connection qualifies as a structural addition.

That triggers:
Structural site plans
Ledger-board connection inspections
Flashing review
Water management requirements

The ledger is the part most homeowners underestimate. Once the pergola ties into the home's wall system, the load path runs through the framing and siding assembly, and every piece of that connection has to be inspected.

Attached designs suit homeowners who want a direct indoor-outdoor transition off a rear door or existing deck and are willing to plan for the longer review path.

We help choose before the design is committed.

Why Frost Depth Matters More for Louvered Pergolas

Permanent pergolas in Central Pennsylvania need concrete footings poured to at least 36 inches below finished grade.

Clay-heavy soils move through winter freeze-thaw cycles. Shallow supports can lift, settle, and shift, which shows up as twisted posts, pulled connections, and a frame that is no longer square.

Open-Beam Pergolas vs. Motorized Louvered Pergolas

For a rough cedar open-beam pergola, minor seasonal movement is a nuisance.

For a motorized louvered pergola, it can become a mechanism failure. Adjustable aluminum louvers operate on tight tolerances. If one column settles or tilts, the louver panels can bind, drag, or stop sealing against rain.

The motor works harder, the frame stresses the hardware, and the waterproofing gap that opens at the low side defeats the purpose of the system.

Foundation Planning for Motorized Pergolas

Foundation planning for motorized pergolas accounts for:

Column loads
Existing slab thickness where posts anchor into hardscape
Patio conditions
Drainage movement around the piers
Long-term frame alignment

The louver system's performance five years out depends on decisions made before the first post goes in.

Rough Cedar Pergolas

Rough cedar suits traditional homes, garden spaces, and patio areas where the texture and warmth of exposed wood matter.

Design options include:

Exposed beams
Decorative rafter tails
Heavier post profiles
Stained or sealed finishes

The details that determine how cedar ages in humid Pennsylvania summers are the ones less visible: fastener selection, post base design, water contact points, and drainage control at the base of each column.

Metal and Aluminum Pergolas

Metal and aluminum systems work for homeowners who want cleaner architectural lines and less seasonal upkeep.

Staining, checking, and moisture management that come with wood are not factors. Corrosion-resistant coatings and hardware protect the structure through wet seasons and winter exposure.

Material Options

Pergola material selection affects the structure’s look, maintenance needs, and long-term performance in Pennsylvania weather.

Motorized Louvered Pergolas

Motorized louvered pergolas give direct control over sun, shade, airflow, and rain.

Our project gallery includes a completed 10×16 VDB Miami Pergola installation featuring:

Adjustable louvers
Integrated drainage
Powder-coated galvanized steel
Built-in power access
Three outlets
Three USB charging ports

The structure is rated for up to 3,100 pounds of load, 12 inches of snow, and wind speeds up to 100 mph.

Pre-Design Pergola Checklist

We check:

Municipality
Parcel zoning district
Impervious coverage where it applies
Freestanding vs. attached classification
Footing depth
Setback rules
Structural review triggers
Inspection path

What Gets Checked Before Design Is Locked In

Every pergola project starts with the same sequence. Style and material choices come after the property, permit, and structural requirements are resolved.

Hummelstown Borough Design Review

For Hummelstown Borough projects, we calculate the 2-foot side setback, 3-foot rear setback, and existing plus proposed coverage against the 40% impervious cap.

Derry Township Design Review

For Derry Township projects, we pull the current permit forms, verify the structural review triggers under Ordinance 114, and coordinate the inspection path before framing begins.

A pergola designed around the wrong setback rules, or installed on footings that do not reach the frost line, creates problems that show up months or years after installation day.

We plan for the property that exists, not the one the mailing address implies.
