Commercial Build-Out Guide

What does a
commercial build-out cost?

Office renovations, retail build-outs, and tenant improvements all follow the same playbook. Here's a clear, no-pressure look at how commercial pricing works — so you can plan your space with confidence.

The Starting Point

Cost per square foot

Most build-outs fall into one of three tiers. The biggest driver is how much of the space already exists — and the level of finish your brand calls for.

Basic
$20 – $35/ sq ft
  • Open-plan layout
  • Standard finishes & lighting
  • Minimal partitions
  • Reuse of existing systems
Most CommonMid-Range
$35 – $59/ sq ft
  • Private offices & conference rooms
  • Upgraded flooring & millwork
  • New HVAC distribution
  • Branded reception & finishes
High-End
$59 – $98+/ sq ft
  • Custom, design-forward space
  • Premium finishes & fixtures
  • Specialized MEP & technology
  • Commercial kitchens or labs
Real Numbers

Example budgets by size

Multiply your square footage by the tier rate and you get a working build-out budget. Here's how that looks across common suite sizes.

Suite SizeBasicMid-RangeHigh-End
2,000 sq ft$40K – $70K$70K – $118K$118K+
4,000 sq ft$80K – $140K$140K – $236K$236K+
6,000 sq ft$120K – $210K$210K – $354K$354K+

Figures are construction estimates only and exclude furniture and equipment. Every space is different — actual costs vary by condition, use, and finishes.

What Moves the Number

Factors that affect cost

Two suites of the same size can land at very different prices. These are the levers that explain the gap.

Space Condition

A first-generation shell needs everything — restrooms, HVAC, electrical, ceilings. A second-generation space with existing improvements can cut your build-out budget substantially.

Mechanical & Electrical

HVAC distribution, panel upgrades, data, and plumbing are often the largest line items in a build-out — especially for restaurants, medical, or high-occupancy uses.

Layout & Partitions

Every wall, door, and private office adds framing, finishes, and often additional mechanical work. Open plans build faster and cost less per square foot.

Finish Level

Flooring, ceilings, millwork, glass fronts, and lighting span a wide range. Finishes are where a branded, design-forward space separates from a basic one.

Time Is Money

Every week of delay is rent without revenue

On a commercial project, the schedule is part of the budget. The faster we open the doors, the sooner the space starts earning. We plan permitting, long-lead items, and inspections up front to keep your project moving forward.

Tight scheduling and transparent communication mean fewer surprises and a firm date you can plan your opening around.

Design & drawings
2 – 4 weeks
Permitting & review
3 – 8 weeks
Construction
6 – 14 weeks

Typical ranges; overlapping phases and early ordering can shorten the overall timeline.

Plan Ahead

Costs that are easy to overlook

The per-square-foot number rarely tells the whole story. Build these line items into your budget early so they don't become surprises.

Ways to control your costs

A few decisions up front protect both your budget and your opening date.

1

Start with a second-generation space

Leasing a space with existing offices, restrooms, and HVAC already in place can save tens of thousands compared to building out a raw shell.

2

Negotiate a tenant improvement allowance

Landlords often contribute toward build-out costs. A clear scope and estimate up front strengthens your position at the lease table.

3

Lock the design before permitting

Changes after drawings are submitted mean redesign, re-review, and lost time. Finalizing the plan early keeps the schedule — and the budget — intact.

The Payoff

Why work with one contractor?

One point of contact from plans to punch list
Tight scheduling that protects your opening date
Transparent, itemized estimates with no surprises
Coordination with your landlord and architect
Local crews who know the parish permit offices
A single team accountable for the finished space
