Commercial Tenant Improvement in Los Angeles — Costs, Process & 2026 Guide

A commercial tenant improvement (TI) is any construction work done to customize a leased commercial space for a specific tenant’s use. Whether you are a business owner building out a new office, a restaurateur fitting out a kitchen, or a retailer creating a custom store environment, a tenant improvement project in Los Angeles requires a licensed general contractor, building permits, and careful coordination between your lease terms, your landlord, and the building department. APLA Construction (CA Lic #1136359) handles commercial tenant improvements throughout Greater Los Angeles for small businesses and property owners.

The TI Permit Process in Los Angeles

All commercial tenant improvements in Los Angeles that involve structural, electrical, plumbing, or mechanical work require building permits. The permit process for commercial TI in the City of LA goes through LADBS and typically involves:

  1. Architectural drawings and MEP plans prepared by licensed design professionals
  2. Plan check submission to LADBS — 4–10 weeks for standard commercial TI
  3. Landlord approval — most leases require the landlord to approve drawings before permit submission
  4. Health department approval (for restaurants and food service businesses)
  5. Fire department review (for occupancies with fire suppression or egress changes)
  6. Construction inspections at rough framing, MEP rough-in, and final

ADA Compliance in LA Commercial TI Projects

California has some of the strictest ADA and accessibility requirements in the United States. When a tenant improvement exceeds 20% of the building’s replacement cost, ADA upgrades to restrooms, parking, path of travel, and building entrance may be required — even if those areas are outside the TI scope. APLA evaluates ADA compliance requirements at the project scoping stage so there are no surprises mid-construction.

Frequently Asked Questions — Commercial Tenant Improvement Los Angeles

How much does a commercial tenant improvement cost in Los Angeles?

Commercial TI costs in Los Angeles range from $40/sq ft for a basic office refresh to $400/sq ft for a full-service restaurant build-out. A 2,000 sq ft office TI at mid-range finishes runs $160,000–$300,000. Restaurant TI for a 1,500 sq ft space typically runs $300,000–$600,000 due to commercial kitchen, ventilation, and health department requirements.

Do I need a permit for a commercial tenant improvement in Los Angeles?

Yes. Any commercial TI involving structural changes, electrical, plumbing, or mechanical work requires a building permit from LADBS (for City of LA properties) or the applicable city building department. Unpermitted commercial work creates liability, can invalidate your Certificate of Occupancy, and creates problems with inspections and lease renewals. APLA handles all permit coordination.

How long does a commercial TI permit take in Los Angeles?

Standard commercial TI plan check at LADBS takes 4–8 weeks for a complete submittal. Restaurant and medical office submittals that require health department or fire department review add 2–4 weeks. Expedited plan check is available at LADBS for an additional fee and can reduce review time to 2–3 weeks.

What is a TI allowance and how do I negotiate one?

A TI (tenant improvement) allowance is money the landlord contributes toward your build-out costs, expressed as a per-square-foot amount. In the current Los Angeles market, allowances for Class B office space typically run $40–$80/sq ft. To negotiate effectively, get a preliminary construction cost estimate before signing the lease — APLA provides these at no charge — so you know the real cost and how large an allowance to push for.

Can APLA help with both the build-out and the permit process?

Yes. APLA manages the full TI process — design coordination, permit submittal, construction, inspections, and final Certificate of Occupancy — under one contract. We have experience with LADBS, health department approvals for restaurants, and the landlord approval processes common in LA commercial leases.
