Contractor shops & flex buildings
Pole buildings, service garages, shop-and-office combinations and small flex space — usually with gravel or paved yard storage that drives the stormwater design more than the building does.
Home / Small Commercial
Projects under five acres — our core commercial work
Putting up a shop, store or office? We’ll get it approved.
A shop, a storage building, an office, a fire hall addition, a barn becoming a business. These projects still have to clear zoning, land development review, erosion control and stormwater — the same gauntlet as a shopping center, on a fraction of the budget. That is the work we are built for.
01 — Project types
What we work on.
Most are between a quarter-acre and five acres of disturbance. Small enough that a large firm's minimum fee doesn't make sense — complicated enough that they genuinely need an engineer.
Self-storage & mini-storage
Nearly all impervious, so stormwater is the whole project. Phased build-outs need a plan that approves the full footprint once instead of returning to the township every two years.
Retail, office & professional
Small storefronts, medical and professional offices, salons, veterinary clinics. Parking counts, accessible routes and access management usually decide whether the layout works.
Churches, fire halls & community buildings
Additions, pavilions, expanded parking and new social halls for organizations running on donated money. Fee certainty matters as much as the design.
Warehouse & equipment storage additions
An addition to an existing building often triggers full land development review for the first time — and brings the whole site, not just the new slab, up to current stormwater standards.
Farm-to-commercial conversions
A shop building rented to a contractor. A barn turned into an event venue or retail. Equipment storage leased out. The change of use brings requirements the structure never had to meet as a farm building, and usually land development review with it. We handle both sides — often we designed the building →
02 — What applies to you
Which approvals your project triggers.
Four independent tracks. A project can trip one, or all four. Knowing which before you buy the ground is worth more than anything else we do.
| Trigger | Threshold | What it means |
|---|---|---|
| Erosion & sediment controls | Any earth disturbance | BMPs must be implemented and maintained on every project, regardless of size. |
| Written E&S plan | 5,000 sq ft or more | A written Chapter 102 erosion and sediment control plan must be prepared and available at the site. |
| NPDES permit coverage | 1 acre or more | Permit coverage through PA DEP or your county conservation district. Between one and five acres you may qualify for the PAG-01 general permit for small construction; larger or ineligible projects use PAG-02 or an individual permit. |
| Post-construction stormwater | Varies by municipality | PCSM obligations under Chapter 102 plus whatever your municipal stormwater ordinance requires — frequently the stricter of the two. |
| Land development plan | Set by local ordinance | Most municipalities require plan review for a new principal building, an addition, added parking, or a change of use. Many offer a shorter "minor" track for small projects. |
| Highway occupancy permit | Access to a state road | A PennDOT HOP is required for any new or altered driveway onto a state route. Township roads are permitted by the municipality. |
| Sealed construction documents | Commercial buildings | Required for the building itself, and produced by your architect. We do the site. |
The one that catches people out
One acre of earth disturbance is not the same as one acre of building. It includes the whole area you grade — driveways, stockpiles, staging, the strip you regrade for a swale, and the disturbed ground around the structure. A 12,000 sq ft building routinely disturbs well over an acre once the yard and access are counted, and that single number decides whether you need an NPDES permit at all.
Before you sign an agreement of sale
The cheapest hour you will ever spend on a project is the one before you own the ground. Zoning that doesn't permit your use, no sewage capacity, a floodplain clip, or an access point PennDOT won't approve are all things we can check quickly — and they are all things that are effectively unfixable afterwards.
03 — Scope
What you get.
Quoted as a fixed fee, by task, so you can see what you are paying for and what you are not.
Design
- Existing conditions and boundary information, from our survey or from yours
- Site layout — building placement, parking, loading, circulation and setbacks tested against the zoning ordinance
- Grading and earthwork, balanced where the site allows it
- Utility layout and coordination; on-lot sewage where public sewer is not available
- Erosion and sediment control plan and details
- Stormwater analysis and post-construction BMP design sized to the governing ordinance
Submission & approval
- Municipal land development or minor plan submission, with the applications, fees and escrow forms compiled
- County planning commission review submission
- County conservation district / PA DEP NPDES package where required
- PennDOT highway occupancy permit application where access is onto a state route
- Written responses to every review comment, through to approval
- Attendance at planning commission and supervisors' meetings as the project needs it
After approval
- Record plan execution and recording coordination
- Contractor questions during construction answered by the people who drew it
- As-built and PCSM completion certification to close the permit out
04 — Timeline
How long it takes.
Most of a small commercial schedule is review time, not drafting time. Knowing that changes how you plan the build.
01
Feasibility
1–2 weeks
Zoning, sewage, access and earth-disturbance check. Enough to know whether the project works and roughly what it will take.
02
Survey & design
4–8 weeks
Field survey, layout, grading, stormwater modeling and E&S design. Longest single stretch we control.
03
Review cycles
2–5 months
Municipal, county and conservation district review run partly in parallel. The Municipalities Planning Code gives the governing body 90 days from the first eligible meeting to act.
04
Approval & build
ongoing
Recording, pre-construction meeting, contractor support, and PCSM certification to close the permit.
How to lose four months
Miss a submission deadline and your plan waits for the next planning commission meeting — typically a month. Submit an incomplete package and it isn't accepted at all, so the clock never starts. Most of the schedule risk on a small commercial project is calendar management, which is exactly why we compile the package rather than handing you a drawing and a list.
05 — Questions
Questions we get asked.
Do I need a site plan for a small commercial building?
Almost always. Nearly every municipality wants a site plan showing boundaries, setbacks, grading, parking and stormwater before it issues a building permit — that site plan is our work.
The building’s own construction documents are a separate thing: Pennsylvania's Uniform Construction Code requires those to be signed and sealed by a PA-licensed architect or professional engineer, and they come from your architect or building designer, not from us.
Separately — and this is the part that surprises people — most municipalities require a full land development plan when you add a principal building, expand parking, or change the use of a property. That is a public review process with its own submissions, fees and meetings, and it runs well beyond the building permit.
My project is small. Can I skip the engineer?
Sometimes, for genuinely minor work — a small addition inside an existing paved area with no new disturbance may need nothing more than a building permit. Below 5,000 square feet of earth disturbance you have no written E&S plan obligation, though you still have to control erosion.
The honest answer is that it depends on numbers we can check in an hour. We would rather tell you that you don't need us than sell you a plan you didn't have to buy.
Can I convert a farm building to commercial use?
Often, yes — and it is a growing share of our work as farms diversify their income. Two things are worth knowing before you sign a lease.
The change of use usually triggers land development review even when you aren't constructing anything, because parking, access, stormwater and sometimes sewage obligations all change with the use.
The building itself may have to meet requirements it never did as a farm structure — commercial occupancy, accessible routes and exiting among them. Worth establishing early, because it can decide whether the conversion is worth doing at all.
Neither makes it a bad idea. Both make it something to price properly first. We handle the farm side as well, so the whole picture gets looked at once rather than twice.
We already have a plan that stalled in review. Can you take it over?
Yes, and it happens more than you would think. Send us the latest review letter and the current plan set. We will tell you honestly whether the fastest route is responding to the comments as drawn or redesigning the part that keeps drawing them.
Got a site and an idea? Let's talk.
Tell us about it and we’ll outline the permits it needs and what work like this generally runs.
