Every garage and two-story structure needs township-approved plans. We work with a licensed structural designer to prepare your plan set — and for many of our standard designs, the plans are already done and included at no extra cost.
Cost depends on whether we already have plans for your design and what your township requires.

Below is a sample 24x24 two-story garage plan set. Watermarked previews shown — full engineering plans are provided with your order.

Full dimensional layout with stair details, beam locations, and code compliance information.

Upper level layout showing guardrail placement, floor joist spacing, and opening locations.

CMU block layout with frost footing details, anchor bolt spacing, and rebar specifications.

Joist layout, beam sizing, and structural connection details for the subfloor system.

Every plan set references IRC 2021 residential code with site-specific loading data — snow loads, wind speeds, seismic category, and frost line depth. Your township sees exactly what they need.
Simpson Strong-Tie hardware is called out at every critical connection — post-to-beam, rafter-to-plate, and post-to-concrete. No guesswork for the inspector.
Frost footing specs, CMU block layout, anchor bolt spacing, rebar requirements, and slab construction details are all drawn and dimensioned. Ready for your concrete contractor.
Plans are drawn by Hallowing Run Structures, a professional structural design firm. Each set is project-specific — not generic templates — customized to your exact size and configuration.
Most townships in Chester County and surrounding areas require a “plot plan” or “site plan” as part of your permit application. Here’s the good news: it’s simpler than you think.
A plot plan is a simple overhead drawing of your property that shows where your existing house sits, where the proposed structure (your new garage or shed) will go, and the distances to property lines (called setbacks). It helps the township verify your project meets local zoning requirements.
Important: A plot plan is NOT the same as a professional land survey. Most townships accept a hand-drawn or printed sketch — you do not need to hire a surveyor.
Property Lines & Dimensions
Show the outline of your lot with approximate measurements. Your deed or county GIS map will have these.
Existing Structures
Mark your house, driveway, any other buildings, septic, and well locations if applicable.
Proposed Structure Location
Draw your new garage or shed in the planned position with its footprint dimensions (e.g., 24’ × 32’).
Setback Distances
Measure and label the distance from your proposed structure to each property line. Your township’s zoning ordinance specifies minimum setbacks.
Send us your address and we can pull your property info from the county GIS system. We’ll help you fill it in — no charge.
