Commercial Construction Cost Guide

Cost is usually the first question an owner asks and the hardest one to answer honestly before there is a real scope to price. This guide explains how commercial construction actually gets priced, so you can read a number and know how much weight it deserves.

Why per-square-foot is a starting point, not an answer

Cost per square foot is a way to compare projects at a glance, not a formula you plug a number into and get a budget out of. The same square footage can price very differently depending on finish level, site conditions, and the mechanical, electrical, and plumbing systems the building needs. A warehouse shell and a medical office of the same size are not the same project, and a per-square-foot figure that fits one will be well off for the other. Treat any single number you find online as a rough gut check for whether a project is in the right order of magnitude, and nothing more.

General industry ranges by building type

The figures below are broad general industry ranges, not a quote and not our prices. They exist only to set expectations at the order-of-magnitude level. Your real number depends on your scope, your site, and current material and labor conditions, and it can land outside these ranges in either direction.

Warehouse and basic shell space: commonly in the lower per-square-foot tiers, because the finish scope is minimal. Retail and restaurant build-outs: a wide range, driven mostly by kitchen loads, storefront work, and how far the brand finish departs from a plain interior. Office and professional space: a middle range that climbs with finish level and density of walls and systems. Medical, dental, and specialized clinical space: among the higher ranges, because of specialty mechanical, electrical, plumbing, and equipment coordination. Use these only to sense-check a concept, never to set a budget you plan to hold a design or a lender to.

Hard costs versus soft costs

Hard costs are the physical construction: site work, structure, envelope, interior build-out, and the trades that put the building together. Soft costs are everything else the project needs to happen: architecture and engineering fees, permits, testing and inspections, insurance, and financing costs. A number that only covers hard costs looks smaller than the real all-in cost, and the gap tends to surface at the worst time, right when a lender or partner asks why the total moved. Build both into your thinking from the start.

What drives the number up or down

Finish level is usually the biggest lever, followed closely by site conditions. A flat, already-graded lot with utilities at the curb is a different project than one that needs earthwork, drainage, or utility extension before the building itself starts. Mechanical, electrical, and plumbing scope is the piece owners underestimate most, because it is largely invisible in a walkthrough but can be a large share of total cost. On top of all that, the market matters: material and labor availability shift over time, so the same building can price differently a year or two apart.

Why a real number needs drawings

A real estimate comes from real scope: a set of drawings or at least a documented program, a defined finish level, and a walk of the site or a real understanding of its conditions. From there a contractor can price the trades that will actually be on your job and account for the site work your specific lot requires. That is the difference between an estimate and a guess dressed up as one, and it is the number that holds up when a lender, a partner, or a board asks where it came from.

We are a licensed and insured general contractor with over 20 years of combined experience building across the greater Houston area, and we self-perform many of the trades that most often move a budget once construction starts. If you are working through an early budget, we are glad to look at your scope and give you a real number instead of a rule of thumb.
