Quick answer: JLL's U.S. and Canada Office Fit Out Cost Guide puts a medium-quality office fit-out at a $295 per square foot national average for 2026, with a typical range of $230 to $375 and style-based ranges spanning roughly $170 to $425. Florida's Gulf Coast generally prices below the national benchmarks, which lean toward corporate space in gateway metros. Your written estimate after a walkthrough is the real number.
The 2026 national benchmarks
The most rigorous published source for office fit-out pricing is JLL's annual U.S. and Canada Office Fit Out Cost Guide. The 2026 benchmarks put the average medium-quality corporate fit-out at $295 per square foot, with a typical range of $230 to $375. JLL also breaks the numbers out by office style, which matters more than any other single choice you will make.
| Office style | Baseline | Medium | High | Full market range |
|---|---|---|---|---|
| Open and agile (mostly open plan) | $255/SF | $275/SF | $310/SF | $170 to $380/SF |
| High spatial variety (mixed) | $275/SF | $295/SF | $340/SF | $180 to $405/SF |
| Structured, traditional (mostly private offices) | $285/SF | $310/SF | $355/SF | $190 to $425/SF |
Where these numbers come from. We publish benchmarks from named sources instead of hiding pricing behind a form. The table above is JLL's U.S. and Canada Office Fit Out Cost Guide, 2026 benchmarks; the prior edition averaged $280 per square foot nationally. JLL's model skews toward corporate fit-outs in major metros and includes more than hard construction, and JLL notes the South and Midwest are the most competitive regions, so many Sarasota and Bradenton suites land below these figures. The written estimate we prepare after walking your space is the real number, and it is free.
What pushes the number up or down
- Private offices and conference rooms. Walls, doors, glass fronts and the HVAC and electrical that serve each enclosed room are the biggest cost lever. That is why JLL's traditional layouts average $30 to $45 per square foot more than open plans at the same quality level. Law firms and financial practices, which want the most private offices, sit at the top of the national spread.
- The condition you start from. A second-generation suite that already has ceilings, HVAC distribution and restrooms costs far less to adapt than a raw shell. Our shell conditions guide explains grey shell, warm shell and white box in plain language.
- Finish level. JLL's baseline-to-high spread within each style runs $55 to $70 per square foot. Flooring, millwork, lighting and glass are where quality shows and where money goes.
- Mechanical and electrical reality. An older building with tired HVAC or a panel at capacity adds cost no finish choice can hide. We check both at the walkthrough, before you commit.
- Plan review and code items. Commercial permits in Sarasota and Manatee counties include fire and accessibility review. Renovations can also trigger accessible path-of-travel upgrades; our ADA and accessibility guide covers the 20 percent rule that governs them.
The allowance gap: what the landlord pays vs what the space costs
Tenants are often surprised that the tenant improvement allowance in the lease covers only part of the buildout. CBRE's survey of roughly 3,900 office leases across 12 major markets put the average office TI allowance at $94.69 per square foot in the first half of 2024, the first decline in four years, alongside an average of 9 months of free rent. JLL's broader national series ran near $75 per square foot in 2024. Set either figure against a $230 to $375 typical fit-out and the difference is the tenant's to fund or negotiate. Our TI allowance guide explains how allowances are structured and what landlords expect in the work letter.
What a Gulf Coast office buildout typically includes
Our office buildout service covers the scope these benchmarks describe: demising walls, framing and ceilings, HVAC distribution and controls, electrical, lighting and data rough-in, glass-front offices and conference rooms, restrooms built to accessibility requirements, millwork, flooring and paint. Our completed work includes a 4,900 square foot white-box-to-move-in buildout on 8th Street West in Bradenton, delivered while the building stayed operational.
How to use these numbers
- Pick your style honestly. Count the private offices you really need. Each one you remove moves you down the table.
- Ask what every number includes. A benchmark with furniture and fees in it will always look worse than a construction-only quote. Compare like with like.
- Get the delivery condition in writing. The same suite can cost wildly different amounts depending on what the landlord delivers. The lease exhibit, not the listing, is the truth.
- Price before you sign. A written scope and estimate before lease signature turns the TI allowance negotiation into arithmetic instead of argument.
Office buildout cost questions
What does an office buildout cost per square foot in 2026?
JLL's U.S. and Canada Office Fit Out Cost Guide puts the national average for a medium-quality office fit-out at $295 per square foot for 2026, with a typical range of $230 to $375 and style-based national ranges running from about $170 at the low end of open-plan layouts to $425 at the top of traditional private-office layouts. Those benchmarks skew toward corporate space in major metros, and JLL notes the South prices below the coastal gateways, so many Sarasota and Bradenton suites land below them.
Why do open-plan offices cost less to build than private offices?
Walls are the expensive part. Every private office adds framing, drywall, a door, glass, dedicated HVAC distribution, more lighting circuits and more data drops. JLL's 2026 national averages show the spread: open and agile layouts average $255 to $310 per square foot depending on quality, while structured traditional layouts with mostly private offices average $285 to $355.
Does the tenant improvement allowance cover a full buildout?
Usually not. CBRE's survey of about 3,900 office leases in 12 major markets put the average tenant improvement allowance at $94.69 per square foot in the first half of 2024, while JLL's broader national series ran near $75. Compare either number with a $230 to $375 typical fit-out range and the gap is the tenant's to fund, which is why the written scope matters before the lease is signed.
Are Sarasota office buildouts cheaper than the national average?
The published benchmarks point that way: JLL notes that coastal gateway markets like New York and San Francisco sit at the top of the range while the South and Midwest are the most competitive. No one publishes a Sarasota-specific per-square-foot survey, so we do not invent one. We price each suite from a walkthrough and a written scope.
What is included in a buildout price per square foot?
It varies by source, which is why comparing quotes to benchmarks goes wrong. JLL's figures include more than hard construction, such as furniture and professional fees in parts of their model. A contractor's quote usually covers construction only: walls, ceilings, HVAC distribution, electrical, data rough-in, finishes. Always ask what a number includes before comparing it to another number.
