Test a Rear-Load Small-Bay Building on Your Parcel
Start from one rear-load small-bay building that sizes itself to your parcel, with storefront offices on the street and a truck loop to the rear docks. You see the building area before the LOI.

Will a Rear-Load Small-Bay Building Fit My Site?
TestFit is real estate feasibility software that generates site plans on your parcel and calculates what they yield. For a single rear-load small-bay building, the answer comes down to three things that are hard to judge from a parcel map.
Trucks have to get behind
With docks on the back, trucks need a route around the building to reach them. A perimeter truck loop does that, and it takes a ring of land off the site.
Two faces, two jobs
The front needs office storefronts and car parking facing the street, and the back needs a truck court. On a shallow parcel, both faces come out of the building's depth.
Size follows the parcel
On a smaller parcel, setbacks and frontage decide whether the building lands near 37k sf or reaches 57k sf. That swing changes the leasable area.
From Your Parcel to a Deal You Can Underwrite
Start from the rear-load small-bay building your team would build, tune it to your standards, and finish with one model for the site, plan, tabulation and pro forma.

Your parcel and its constraints
- Site boundary: pick the parcel from built-in parcel data with current owner info, draw it, enter metes and bounds, or import a KML/KMZ file
- Setbacks and frontage: front, side and rear setbacks set to the parcel edges
- Zoning: FAR, building and impervious coverage, height limits and parking ratios, pulled in for your parcel so you don't have to dig through the zoning code
- Easements: areas the layout keeps buildings out of
- Site conditions: flood zones, wetlands and topography from Site Intelligence
Every layout starts inside your site's real constraints.

Your product, fine-tuned on the site
- Product: 1 rear-load small-bay building, 28 ft clear, flexible size from 37k to 57k sf
- Site layout: office fronts and car parking facing the street, rear truck court, perimeter truck loop
- Your edits: building size, units, docks, court, parking and circulation
You see the building your team would propose, on your parcel.

A source of truth for the deal
- Site plan geometry: buildings, courts, parking and drives drawn to the parcel
- Tabulation for this product: building sf, dock doors, trailer and car stalls against what's required, site coverage and FAR
- Earthwork: cut and fill for the layout
- Financials: the geometry turned into development costs, revenue and returns
- Shareable results: a link or PDF report for your team, partners and other stakeholders
You know whether the deal works, with numbers to back it.

Rear-Load Small-Bay Site Planning FAQ
What is a rear-load small-bay industrial building?
A shallow multi-tenant building with office fronts facing the street and dock doors on the back. Tenants get a clean storefront and loading stays out of sight.
How is this different from the rear-load park with a truck court?
This layout tests one building that flexes to fit a smaller parcel, with a loop to reach the rear docks. The park layout places several buildings back to back around a shared court on a larger site.
How much land does a rear-load small-bay building need?
Enough for street-facing parking in front, a truck court behind and a drive connecting the two. Frontage and depth matter more than acreage. Load your parcel in TestFit with this layout to see the building size it supports.
Why does a rear-load building use a truck loop?
Trucks have to reach docks on the side away from the street. The loop carries them around the building and back out without crossing the customer parking in front.
Can I change the layout after it generates?
Yes. Start from this layout, then edit the building, units, docks, parking and circulation in TestFit. The site plan and yield recalculate as you go.
