> Landlord delivers the space fully fit out per tenant spec.

## TL;DR

- Landlord delivers the space fully fit out per tenant spec.
- Landlord designs, permits, and constructs the entire fit-out, then hands keys to the tenant.

# Turn-key build-out

*Construction · US*

## Short definition

Landlord delivers the space fully [fit out](/topics/fit-out-capex) per tenant spec.

## Full definition

Landlord designs, permits, and constructs the entire [fit-out](/glossary/fit-out), then hands keys to the tenant. The tenant's [TI allowance](/topics/us-tia-strategy) becomes a build-out cap; overruns are tenant's cost.

## Why this matters for Class A leasing

Turn-key build-out is part of the construction vocabulary that institutional [Class A](/glossary/class-a) occupiers, landlords, and advisers use across US markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the US definition alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
