Opening or expanding a business location in Los Angeles involves a construction project — whether you call it a tenant improvement, a fit-out, or a build-out. The terminology varies, but the challenge is consistent: you have a lease that starts on a specific date, a budget that feels tight, and a city permitting system that doesn't move on your schedule.
This guide is written for business owners who are navigating a commercial build-out in Los Angeles for the first time — or for the second time after the first one didn't go as planned.
What Is a Commercial Build-Out?
A commercial build-out or tenant improvement (TI) is the construction work required to transform a raw commercial space (or an existing space left by a previous tenant) into a space configured for your specific business. The scope varies enormously:
- Second-generation space: The previous tenant left it in good condition, you're making modest changes — new paint, flooring, a few walls — to adapt it to your use. Lower cost, faster timeline.
- First-generation/white box space: Raw shell space with concrete floors, exposed ceilings, and only base building mechanical (HVAC, electrical main panel) provided. Requires full build-out. Higher cost, longer timeline.
- Full gut: Existing buildout from a prior tenant that doesn't work for your use and needs to come out. Somewhere in between.
What Does a Commercial Build-Out Cost in LA?
Commercial build-out costs in Los Angeles in 2026:
Office space (second-gen, modest modifications): $40–$80/sq ft. New flooring, paint, minor demo, tech infrastructure, lighting updates.
Office space (first-gen/full fit-out): $80–$160/sq ft. Full partitioning, ceiling tiles, HVAC distribution, electrical, lighting, flooring, restroom upgrades, break room.
Retail space: $80–$200/sq ft depending on use. A clothing boutique needs different infrastructure than a coffee shop; a coffee shop needs different infrastructure than a medical spa.
Restaurant: $200–$500+/sq ft. Commercial kitchens, Type I hood systems, grease interceptors, elevated electrical loads (208V three-phase service), plumbing for multiple sink stations — restaurants are among the most expensive spaces to build per square foot.
Medical/dental office: $150–$350/sq ft. Medical gas, specialized plumbing, electrical for equipment, lead-lined walls (dental X-ray rooms), ADA compliance requirements.
The Landlord TI Allowance
Most commercial leases in LA include a Tenant Improvement (TI) allowance — a dollar-per-square-foot contribution from the landlord toward the cost of your build-out. Common TI allowances in current LA market:
- Lower-quality or challenging locations: $20–$50/sq ft
- Mid-range office or retail: $50–$100/sq ft
- Premium office in strong submarkets: $100–$150+/sq ft
The TI allowance is typically structured as a reimbursement after construction is complete and the tenant has provided lien waivers from all contractors. It is not a credit applied at lease signing.
Key negotiating point: The TI allowance amount is negotiable. In the current leasing market, there's often room to negotiate a larger allowance, especially if you're committing to a longer lease term.
Permitting a Commercial Build-Out in Los Angeles
Commercial construction in LA involves more regulatory touchpoints than residential:
Building Permits (LADBS or local jurisdiction)
Required for any structural work, new partitions, changes to egress (exits), plumbing, electrical, HVAC. For most commercial build-outs, plan check is required before permits are issued. LADBS commercial plan check currently takes 6–12 weeks for over-the-counter submittal; expedited review is available for a fee.
Fire Department Review
The LA Fire Department reviews plans for sprinkler systems, fire alarm systems, and egress compliance. This is a parallel review process to LADBS and may add time to the approval sequence.
Health Department (for food service)
Any food service operation — restaurant, café, commercial kitchen, even certain food retail — requires review and approval from the LA County Department of Public Health (or city equivalent). Health department approval is separate from and in addition to building permits.
ADA Compliance (Title III)
Any commercial space open to the public must comply with ADA accessibility requirements. Key areas: accessible entrances, accessible restrooms, accessible paths of travel within the space, accessible service areas. For tenant improvements, the "path of travel" requirement means that if you're doing significant work inside the space, you may need to upgrade the accessible path from the parking lot to your entrance as well.
Non-compliance with ADA is not just a permit issue — it creates civil liability exposure. ADA compliance lawsuits against California businesses are common. Don't build a space that isn't compliant.
The Lease Commencement Trap
The most common mistake business owners make in commercial build-outs: signing a lease with a fixed commencement date before the build-out is designed, permitted, and contracted.
The sequence that leads to disaster: sign lease → start design → submit for permits → discover plans need revision → permits delayed → construction starts late → lease commencement arrives → construction isn't done → you're paying rent on a space you can't occupy.
The sequence that works: have a detailed scope and preliminary design complete before lease signing → negotiate a permitting contingency or a free-rent period of sufficient length → get permits before construction starts → build to your actual timeline.
If a landlord won't give you adequate free-rent or permitting contingency protection, that's risk you're accepting. Price it accordingly.
Finding a Commercial Contractor in LA
Commercial construction is a different discipline from residential. Your kitchen remodeler — however good — isn't the right contractor for your commercial build-out. Look for:
Commercial GC experience. Ask for a list of completed commercial projects with contact references. Call those references.
Familiarity with LADBS commercial permitting. The commercial permitting process at LADBS has specific requirements that differ from residential. An experienced commercial contractor knows how to submit plans correctly, respond to corrections efficiently, and keep the schedule moving.
Bonding. Commercial landlords typically require contractors to be bonded. Make sure your contractor can provide a payment and performance bond if required.
Schedule transparency. Get a construction schedule as part of your bid. A contractor who can't provide a schedule before construction starts can't commit to a completion date.
