Tenant improvement (TI) allowances are one of the most common negotiating points in a new commercial lease, and one of the most operationally involved parts of onboarding a new tenant. Here's how they work and what good coordination looks like.
What a TI allowance is
A TI allowance is a dollar amount (often expressed per square foot) that the landlord contributes toward a tenant's build-out costs — fitting out a raw or previously-occupied space to suit the incoming tenant's needs. It's typically negotiated as part of the lease and can be structured as a direct payment, a rent credit, or a reimbursement against submitted contractor invoices.
What the allowance can and can't be used for
Lease language should specify exactly what qualifies — permanent improvements like flooring, walls, and fixtures typically qualify, while a tenant's furniture, equipment, or signage often don't. Ambiguity here is a common source of disputes mid-project, so this should be nailed down at lease signing, not during construction.
The coordination work behind a TI project
- Scope definition — working with the tenant to finalize drawings and a detailed scope of work before any contractor is engaged
- Contractor bidding — sourcing multiple bids from vetted contractors to ensure competitive, accurate pricing
- Budget tracking — monitoring actual costs against the allowance in real time, since overages need to be flagged to the tenant early, not discovered at project completion
- Permit and compliance coordination — ensuring any required permits are pulled and inspections scheduled
- Timeline management — TI delays often push back a tenant's opening date, which has real revenue consequences for them and can affect rent commencement terms
Where TI projects most often go wrong
- Unclear allowance terms leading to disputes over what's reimbursable
- No independent project oversight, leaving the tenant's contractor effectively unsupervised on landlord-funded work
- Poor documentation of invoices and change orders, making it hard to reconcile actual spend against the allowance
- No clear process for allowance overages — who pays, and how it's resolved, should be defined before it becomes a live problem
Why active project management matters here specifically
TI projects sit at the intersection of construction management, lease compliance, and tenant relations — a rare combination that benefits directly from formal project management discipline: clear scope, tracked budget, and a defined critical path from lease signing to tenant move-in.
