Local pricing, permitting and delivery for the Boise market. Researched estimates, not a quote form.
Boise is served out of our Boise logistics lane. Working figure for modular buildings in the Boise market is $335 per square foot for a Signature build before site work, with freight running around $17,000 per module over roughly 2,500 loaded miles. A metro population near 795 thousand means subcontractor availability for the site scope is generally workable, which matters more to your schedule than most buyers expect.
What the jurisdiction requires. Boise falls under Idaho Residential Code based on IRC. Boise is among the fastest-growing metros in the country and modular supply is tight. Before we quote, we confirm the zoning district, setbacks, whether the parcel sits in a flood zone, and whether the local authority has a defined pathway for factory-built structures. In Idaho, that answer is usually available in a single phone call, and it changes the design if you get it late.
In Boise the practical constraint is usually placement rather than permitting. We look at where the truck can stop, how far the crane has to reach from there, and whether utilities can be trenched a short distance or a long one. Those three answers move the site number more than any finish upgrade.
We watch the Boise queue closely because it moves. Steel and finish material lead times tightened this year and seasonal demand compresses the calendar going into spring. The window we quote you is what the line can actually hold today, which is why it is a range rather than a promise.

A production line orders in bulk, cuts to optimized lengths, and recycles offcuts across dozens of units. Site-built framing typically sends fifteen to twenty percent of delivered material to a dumpster you paid to rent and paid again to haul. Lower waste is part of why the per-square-foot number comes in lower, and it is the part nobody puts in the brochure.
The trade shortage is the single biggest schedule risk in construction right now. Factory production concentrates skilled labor in one facility where crews repeat the same operations daily instead of assembling a new subcontractor roster for every project. You are not waiting three weeks for an electrician to have an opening.
A module has to be structurally sound enough to be lifted by crane, hauled at highway speed, and set without racking. That requirement forces heavier framing, more fasteners and engineered connections than code minimum for a comparable site-built structure. The transport requirement quietly produces a stronger building — which is exactly why factory-built performs well under high wind loads.
The reason site-built budgets drift is that the price is discovered as the work proceeds. Factory pricing is set when the design is locked, because the production cost of a known module is known. The variable that remains is site work — foundation, utilities, access — which is why we quote that separately and in the open instead of burying it.
We start with what the site will actually allow: zoning, setbacks, utility availability, flood zone, access width for a truck and crane, and whether the jurisdiction has a defined modular pathway. This is where projects get saved or killed, and it costs nothing to find out.
Layout, finish level and options are locked, and the price for the building is set at that point. Site work is priced separately and transparently, because that is the number that varies with your specific lot and the one most suppliers hide until you are committed.
Plans go to the state modular program or local authority while the site work begins. Running these concurrently rather than sequentially is where most of the schedule advantage lives.
Your unit enters the line. Framing, envelope, mechanical rough-in, insulation, drywall, finish, fixtures and cabinetry happen at successive stations with inspection at each. You get progress documentation rather than guesses.
Foundation is poured or set, utilities are trenched and stubbed, access is prepared for the delivery truck and crane. This runs while your unit is in production.
Modules are transported and craned onto the foundation. For a single-module building this is typically a matter of hours, not days — the set itself is the fastest part of the entire project.
Marriage lines are joined, mechanicals and utilities are connected, exterior finishes are completed at the seams, final inspection is called, and you get your certificate of occupancy along with documentation.
Module dimensions are constrained by what can legally travel a highway, which is roughly sixteen feet wide per module before special permitting. That constrains module width, not building design. Combine modules, stack them, add site-built connective elements, and the layout freedom is closer to conventional construction than most people expect.
Conventional, FHA, VA and USDA products all finance modular construction on a permanent foundation. What differs is the draw structure: factories require deposits at order and progress payments during production, which does not match a standard construction draw schedule. That mismatch is a paperwork problem, and lenders who do this regularly have products for it.
The cost advantage comes from process — bulk purchasing, reduced waste, no weather delays, concentrated labor — not from thinner materials. Transport loads actually require heavier framing than code minimum. If someone is selling you a low number by reducing specification, that is a supplier problem, not a modular problem.
