- Build To Suit (BTS)
- A real estate arrangement in which a developer constructs a commercial building to a specific tenant's requirements in exchange for a long-term lease commitment.
- Rent Commencement Date
- The contractually defined date on which the tenant's obligation to pay base rent begins, typically tied to a certificate of occupancy or substantial completion milestone.
- Substantial Completion
- The point at which construction is complete enough for its intended use, even if minor punch-list items remain — the trigger for most rent commencement clauses.
- Tenant Improvement Allowance (TIA)
- A dollar amount the landlord or developer agrees to contribute toward finishing or customizing interior spaces to the tenant's specifications.
- Triple Net Lease (NNN)
- A lease structure in which the tenant pays base rent plus all operating expenses — property taxes, insurance, and maintenance — in addition to any build-out costs.
- Punch List
- A list of minor incomplete or defective construction items identified at substantial completion that the developer must remedy before the lease obligation fully commences.
- Construction Specifications
- Detailed technical documents describing the materials, dimensions, systems, and standards to which the building must be constructed.
- Force Majeure
- A clause that excuses a party from performance obligations when construction delays are caused by events outside their control, such as natural disasters, labor strikes, or material shortages.
- Guaranteed Maximum Price (GMP)
- A contractual ceiling on total construction cost, above which the developer — not the tenant — bears the cost overrun risk.
- Certificate of Occupancy (CO)
- A document issued by the local building authority confirming that a structure meets applicable building codes and is safe for its intended use.
- Estoppel Certificate
- A signed statement by the tenant confirming the current status of the lease — commencement date, rent amount, and absence of defaults — often required by lenders financing the project.
