Commercial Buildout Terms, Defined

Money the landlord contributes toward buildout costs, negotiated per square foot as part of the commercial lease.

A landlord-provided sum to cover the cost of constructing or improving a commercial space for a tenant's use.

A commercial space delivered with basic infrastructure in place — power, HVAC, plumbing stub-outs — but no tenant-specific finishes.

A step above white box — commercial space delivered with finished restrooms, upgraded HVAC, and move-in-ready common infrastructure.

A bare commercial space with only the building structure — no HVAC, no electrical distribution, no plumbing. The tenant installs everything.

A building delivery condition where the developer completes the structural frame, envelope, and central systems but leaves individual tenant floors unfinished.

An arrangement where a landlord or developer constructs or retrofits a commercial space specifically to a tenant's requirements before the lease begins.

A commercial lease where the tenant pays base rent plus property taxes, building insurance, and maintenance costs on top.

A buildout arrangement where the landlord constructs the space to the tenant's specifications and delivers it ready to open — no construction management required from the tenant.

The landlord's standard building systems delivered to a tenant suite — typically the structural shell, HVAC capacity, electrical service to the suite, and building-standard restrooms.

Alterations made to a leased commercial space to customize it for a tenant's use — and the accounting term for those improvements as depreciable assets on the tenant's balance sheet.

The licensed professional who manages the entire construction project — hiring subs, pulling permits, and delivering the finished space.

A project delivery method where one entity handles both architectural design and construction under a single contract.

A written authorization modifying the original construction contract's scope, cost, or schedule after work has begun.

A final list of unfinished items or deficiencies that must be corrected by the contractor before the project is considered complete.

The phase of construction where plumbing, electrical, and HVAC systems are installed inside walls and floors before surfaces are closed up.

The partition wall that separates one tenant's leased space from an adjacent tenant's space or from the building's common area.

A written document describing exactly what work will be done, by whom, and to what standard in a construction project.

The process of reducing project costs by substituting materials, methods, or specifications without compromising core function or quality.

The complete set of drawings and specifications issued for permit and contractor bidding — the final, buildable version of the design.

The direct construction expenses in a buildout — labor, materials, and equipment installed permanently into the space.

Professional fees, permits, and non-construction expenses that support a buildout without being physically built into the space.

A budget reserve — typically 10–20% of hard costs — set aside for unexpected costs, scope changes, and unforeseen conditions during a commercial buildout.

A document signed by a contractor or supplier releasing their right to file a mechanic's lien against a property in exchange for payment.

Mechanical, Electrical, and Plumbing — the three core building systems that make a commercial space functional.

A commercial exhaust hood with grease filters and fire suppression required over all cooking equipment that produces grease-laden vapors.

A plumbing device that captures fats, oils, and grease before wastewater enters the municipal sewer system.

An automatic system that detects and extinguishes fires, required in most commercial spaces and mandated over cooking equipment in food service.

Heating, ventilation, and air conditioning — the mechanical system that controls temperature, humidity, and air quality in a commercial space.

A government-issued document confirming a building or commercial space has been inspected and meets code for its intended use.

Meeting the accessibility requirements of the Americans with Disabilities Act for commercial spaces open to the public.

The maximum number of people permitted in a commercial space at one time, calculated by the building code based on use type and square footage.

The building department's review of construction drawings to verify code compliance before a building permit is issued.

A government authorization required before starting construction, alteration, or demolition work on a commercial space.

The path of travel from any point in a building to a safe public area outside — exits, corridors, and doorways that allow emergency evacuation.
