Quick Answer: A tenant improvement is any modification to a leased commercial space to fit your business needs, while a build-out typically involves more extensive construction of a raw space. Most costs are covered by a landlord's tenant improvement allowance, with anything beyond that your responsibility. Terms are highly negotiable.
Commercial build-outs and tenant improvements are the construction and finishing work that turn a raw or generic commercial space into one ready for your specific business. This guide answers the questions Franklin business owners and investors ask most often when negotiating leases, planning renovations, and budgeting for a new space in 2026.
A tenant improvement (TI) is any modification made to a leased commercial space to fit a specific tenant's needs — things like walls, flooring, lighting, plumbing, and HVAC adjustments. The term covers everything from a fresh coat of paint to a full interior reconstruction, depending on what your business requires.
In practice, the terms overlap, but "build-out" usually describes more extensive work — taking a shell space and constructing the interior from scratch. Tenant improvements often refer to modifications of an already-finished space. Many Franklin leases use both terms interchangeably, so always read the lease for the actual scope defined.
It depends on what you negotiate. Landlords commonly offer a tenant improvement allowance, a set dollar amount (often quoted per square foot) they'll contribute toward the work. Anything beyond that allowance typically comes out of your pocket, so the size of the allowance is one of the most important lease terms to negotiate.
A tenant improvement allowance is the amount a landlord agrees to contribute toward customizing your space, usually expressed as a per-square-foot figure. If you're leasing 2,000 square feet with a $30 per square foot allowance, that's $60,000 toward your build-out. Understanding exactly what the allowance covers — and what it doesn't — prevents surprises later.
A turnkey build-out means the landlord delivers the space fully finished to agreed specifications, and you walk in ready to operate. With turnkey arrangements, the landlord manages the construction and absorbs cost overruns, but you typically have less control over finishes and timing. It's a popular option for busy professionals who'd rather not manage a project.
Timelines vary widely based on scope, but most build-outs run anywhere from a few weeks for cosmetic work to several months for major construction. In Franklin, the permitting and inspection process through the City of Franklin or Williamson County adds time you'll want to plan for. We always recommend building a schedule buffer, because permit reviews and contractor availability can shift.
Most build-outs that involve structural changes, electrical, plumbing, or mechanical work require permits through the City of Franklin's building department. Even some cosmetic projects may trigger requirements depending on occupancy type and code. You can review building and permitting requirements through the City of Franklin's official website. When in doubt, confirm before any work begins.
A shell space is delivered with the basic structure — exterior walls, roof, and sometimes rough utilities — but no interior finishes. A finished or second-generation space already has interiors from a previous tenant. Shell spaces give you full design freedom but require more build-out investment, while second-generation spaces can save money if the existing layout fits your needs.
Second-generation space is a commercial unit that was previously occupied and built out by another tenant. If a former restaurant space already has plumbing, grease traps, and a hood system, a new restaurant tenant can save significantly by reusing that infrastructure. We often steer clients toward second-gen spaces when the prior use closely matches their business.
Start with the allowance the landlord offers, then get bids from licensed contractors for your specific scope. Beyond construction, budget for design, permits, signage, furniture, fixtures, and equipment — these "soft costs" add up and aren't always covered by an allowance. Building in a contingency of 10 to 15 percent helps absorb the unexpected.
Yes — build-out terms are some of the most negotiable parts of a commercial lease. The allowance amount, who controls the construction, free rent during build-out, and ownership of improvements at lease end are all on the table. Our team helps Franklin tenants and landlords negotiate these terms so the responsibilities and costs are clear before anyone signs.
In most cases, permanent improvements — walls, built-in fixtures, flooring — become the landlord's property when the lease ends. Removable items like furniture and certain equipment usually stay yours. Your lease should spell out exactly what you can take, what you must leave, and whether you're responsible for restoring the space to its original condition.
It depends on the lease structure. With a turnkey deal, the landlord typically handles the contractor. With an allowance arrangement, you often have the freedom to hire your own licensed contractor, which gives you more control over quality and cost. Always confirm whether the landlord requires approval of your contractor selection.
Lock down your scope early, choose an experienced contractor familiar with Franklin's permitting process, and submit permit applications as soon as plans are ready. Delays most often come from late design decisions, change orders mid-project, and permit backlogs. Clear communication between you, your landlord, and your contractor keeps the project moving.
