Understanding TI Allowances

How tenant improvement dollars work in commercial leasing.

What Is a TI Allowance?

A TI (Tenant Improvement) allowance is the dollar amount per square foot a landlord contributes toward customizing a commercial space for a new tenant. The landlord typically amortizes this cost into the rent over the lease term. Higher TI = higher rent, but a better-fitted space.

Typical TI Ranges

Office (second generation): $20–$45/SF. Office (new/build-to-suit): $50–$100/SF. Retail: $15–$40/SF. Medical/dental: $60–$120/SF. Industrial: $5–$20/SF. The range depends on existing condition, market competition, and lease length.

TI vs Turn-Key vs As-Is

TI allowance: landlord gives you a budget, you manage construction. Turn-key: landlord builds to your specs. As-is: no improvements, lowest rent. TI gives the most control over quality and design. Turn-key is simplest but you may not control costs.

Negotiating TI Allowances

Longer lease = more TI leverage. Landlords amortize TI over the lease term, so a 10-year lease may justify 2x the TI of a 5-year lease. Credit-worthy tenants get better TI packages. In soft markets, TI allowances increase as landlords compete for tenants.

  3. 3
    One advisor, start to finish. No handoffs. No vanishing acts. One person who knows your deal.
