Tenant improvements &
office build-outs.

Commercial tenant improvement contractor in Los Angeles, serving West LA and the Westside — office, medical, and retail tenant improvements and build-outs delivered on time, including work in occupied buildings.

Tenant improvements — also called build-outs or leasehold improvements — are the heart of what we do. As a commercial tenant improvement contractor in Los Angeles, we handle office, medical, and retail tenant improvements across West LA and the Westside. Whether a landlord is repositioning vacant space for a new tenant or a business is fitting out a suite to match how it works, ASEP delivers build-outs that are planned precisely, permitted properly, and completed on schedule.

Office, medical & retail build-outs

From open-plan offices and medical suites to retail tenant spaces, we handle the full scope of commercial tenant improvement work across West LA and the Westside. One accountable team manages design coordination, construction, and finishes.

Built for occupied buildings

Much of LA's TI work happens in buildings that are still in use. We sequence and stage work to keep neighboring tenants operating, manage noise and access, and meet building-management requirements without slipping the schedule.

LADBS permitting handled

We manage LADBS permitting and code compliance end to end. Because commercial plan check in Los Angeles can take time, we plan for it from day one so approvals don't become the bottleneck.

Common Questions

Good to know.

What's the difference between a tenant improvement and a build-out?

They're essentially the same thing. “Tenant improvement” (TI) is the term used more often by commercial real estate agents and landlords, while “build-out” is more common in the construction industry. “Leasehold improvement” means the same as well. All describe interior work to make a commercial space fit a tenant's needs.

What affects the cost of an office build-out in LA?

Cost depends on the size of the space, the existing condition, the level of finishes, and how much the layout and systems (electrical, HVAC, plumbing) need to change. Medical and specialty spaces cost more due to added requirements. We provide a clear, itemized estimate so there are no surprises.

Do you handle the permitting?

Yes. We manage LADBS permitting and code compliance for your project end to end, and we plan around plan-check timelines so they don't delay your move-in.

Can you work while my business stays open?

Yes. We routinely work in occupied buildings, sequencing the work to keep you and neighboring tenants operating with minimal disruption.

Are you licensed, bonded, and insured?

Yes. ASEP Contractors holds California license CSLB #1093086 and is fully bonded and insured. Our work is led by a licensed professional, and we're happy to provide verification on request.

How do you keep projects on budget?

We provide a clear, itemized estimate up front and manage scope, schedule, and change orders closely throughout. If something needs to change, we flag it early with pricing before any work proceeds — no surprise costs at the end.

Repositioning or fitting out a space?

On time, on budget, and communicated every step of the way.
