Signing a Commercial Lease in California? Read This Before You Commit.

Signing a lease on a commercial space? The tenant improvement process can make or break your budget and your opening date.

Here is what we see trip up business owners most — and why the time to address it is before you sign, not after.

Underestimating Scope

That move-in ready space may still need code upgrades, ADA path-of-travel work, or mechanical changes the moment you pull a permit. Cosmetic improvements almost always trigger a review of existing conditions. What looks like a paint-and-carpet job can become a code compliance project before your first inspection.

Accessibility Triggers

In California, a tenant improvement can trigger required accessibility upgrades beyond your suite — restrooms, parking, entrances, and the accessible route connecting them. Many owners find out mid-project when the plan checker flags it and the budget has already been committed.

This is not optional. California Building Code Chapter 11B requires path-of-travel upgrades up to 20% of the primary construction cost any time a primary function area is altered. The scope of your remodel determines the scope of your compliance obligation.

TI Allowance Gaps

The landlord's allowance rarely covers everything — especially when accessibility upgrades, permit fees, and code compliance items are added to the scope. Knowing the real construction cost before you sign gives you negotiating power. Knowing it after gives you a problem.

Permit Timelines

Plan review times vary widely by city and jurisdiction. In some Central Valley cities, over-the-counter approvals are possible for simple scopes. In others, plan check can take weeks. Your rent often starts before your doors open, and every week of delay costs money.

The Solution
