Read the Fine Print Before the Build-Out: Making Tenant Improvement Allowances Stretch in South Texas

Signing a commercial lease in South Texas often comes with a number attached that seems like a gift: the tenant improvement allowance. Landlords in McAllen, Corpus Christi, and San Antonio routinely offer these TI dollars to help tenants customize their space. But anyone who has watched an allowance evaporate halfway through a build-out knows the number on the lease and the number on the contractor's estimate rarely match. Understanding how TI allowances are calculated — and what they quietly exclude — is one of the most important financial steps a tenant can take before committing to a space.

How Landlords Arrive at That TI Number

Tenant improvement allowances are not arbitrary, but they are not tailored to your plans either. Most landlords calculate TI based on dollars per square foot, typically ranging from $20 to $50 per square foot in South Texas markets, depending on the age of the building, the strength of the tenant's covenant, and the length of the lease term. A ten-year lease from a well-capitalized tenant will command a richer package than a three-year term from a startup.

The critical thing to understand is that the allowance is usually benchmarked to what the landlord considers a "standard" build-out — essentially carpet, paint, and modest modifications. If your vision involves anything beyond that baseline, the gap comes out of your pocket.

What TI Dollars Typically Don't Cover

This is where budgets break. The most commonly excluded items are often the most essential:

• HVAC upgrades. Landlords frequently treat rooftop units as building infrastructure. If your restaurant or medical office needs additional tonnage or dedicated zones, expect to fund it separately.
• Electrical panel work. Expanding a panel or bringing service up to modern capacity is usually classified as a capital improvement to the building, not a tenant improvement.
• Code compliance corrections. If bringing your space up to current ADA, fire, or accessibility standards requires upgrades to the base building, the lease language determines who pays — and landlords rarely volunteer for that responsibility.
• Exterior signage and façade work. Many tenants assume signage is included. It frequently is not.

Before negotiating, ask the landlord's broker for a list of items the allowance excludes. That list is more valuable than the allowance figure itself.

Running Real Numbers in South Texas Markets

Build-out costs vary significantly across the region. In McAllen and the Rio Grande Valley, competitive bidding among local trades can keep costs moderate, though specialized work such as medical build-outs commands a premium. Corpus Christi's coastal environment adds requirements — corrosion-resistant materials and wind-rated components — that inflate budgets relative to inland markets. San Antonio's rapid commercial growth has pushed labor and material costs upward, particularly for electrical and mechanical work.

A practical exercise: before signing the lease, engage a general contractor to produce a preliminary budget for your intended build-out. Compare that number against the offered allowance, then negotiate the difference in one of three ways — a higher allowance, additional months of rent abatement, or landlord-funded base building improvements completed before handover.

Negotiation Leverage Tenants Overlook

Tenants often assume the first TI offer is final. It rarely is. Consider these approaches:

1. Trade allowance for term. Landlords value longer leases. Extending a term by two or three years in exchange for $10 more per square foot in TI is often an easy trade.
2. Convert dollars to abatement. If the landlord won't move on allowance, additional rent-free months can fund the same gap.
3. Split the scope. Ask the landlord to handle base building items — panel upgrades, restroom modernization, code work — outside the allowance while your TI covers finishes and layout.
4. Clarify the mechanics. How are TI funds disbursed? Monthly reimbursements against invoices are standard; lump sums at completion are rare. Confirm whether unused allowance is forfeited or credited.

Bring Your Contractor to the Table Early

The single most effective step a tenant can take is involving a contractor during lease negotiation, not after. A contractor can review the letter of intent, flag exclusions, and give the landlord's team realistic cost figures — which strengthens your request for additional allowance. Landlords respond to documentation, not assertions.

A tenant improvement allowance is a negotiating starting point, not a finished budget. South Texas business owners who treat it that way — running real numbers, reading exclusions closely, and leveraging term for dollars — consistently end up with spaces that match their vision without a second round of surprise spending. The clock starts when the lease is signed; the smartest work happens before it is.
