Retail Tenant Improvement: What Business Owners Need to Know

You've found the space. The location is right, the square footage works, and you're ready to sign. But before you do — do you understand what it will actually take to turn that empty shell into a functioning retail location?

Tenant improvement (TI) construction is one of the most misunderstood processes in commercial real estate. Business owners routinely underestimate the cost, the timeline, and the complexity. At Artisan & Co., we've built out retail spaces across Los Angeles — restaurants, boutiques, salons, fitness studios, medical offices, and more. Here's what you need to know.

Tenant improvement (TI) refers to the construction work done to customize a leased commercial space for a specific tenant's use. This can range from minor cosmetic updates (paint, flooring, lighting) to a full gut buildout (new walls, plumbing, electrical, HVAC, storefront).

The scope depends on:

• The condition of the space (vanilla shell, warm shell, cold shell, or second-generation)
• Your specific business requirements
• What the landlord is willing to contribute

Before you can estimate your buildout cost, you need to understand what you're starting with.

Cold Shell (also called "gray shell"): The most basic condition. Four walls, a roof, a concrete floor, and utilities stubbed to the space — but nothing finished. No HVAC, no interior walls, no plumbing beyond a stub, no electrical beyond a panel. Expect the highest buildout costs.

Vanilla Shell: A step up from cold shell. Typically includes finished ceilings, basic HVAC, electrical panel with some circuits, restroom rough-in, and sometimes basic lighting. Still requires significant work to make retail-ready.

Warm Shell: More finished — may include HVAC, lighting, restrooms, and sometimes flooring. Common in newer retail centers.

Second-Generation Space: A previously occupied space. May have existing improvements you can reuse (plumbing, HVAC, some walls) which can significantly reduce buildout costs — or existing improvements you need to demo, which adds cost.

Always ask the landlord for a detailed description of what's included in the shell condition before signing. Vague lease language about "vanilla shell" has cost many tenants tens of thousands of dollars in unexpected buildout costs.

Most commercial leases include a Tenant Improvement Allowance — money the landlord contributes toward your buildout. It's typically expressed as a dollar amount per square foot (e.g., "$50/SF TI allowance").

How TI allowances work:

• The landlord pays up to the allowance amount toward your approved buildout costs
• You pay anything above the allowance
• Allowances are typically disbursed as reimbursements after work is complete and invoices are submitted
• Some landlords pay contractors directly; others reimburse the tenant

Negotiating your TI allowance: TI allowances are negotiable. In a tenant-favorable market, landlords may offer $50–$100/SF or more for desirable tenants. In a tight market, you may get nothing. The allowance is often tied to lease length — longer leases typically come with larger allowances.

Important: A TI allowance is not free money. It's typically amortized into your rent. A higher allowance often means a higher base rent. Understand the full economics before negotiating.

Retail buildout costs in LA vary enormously based on the type of business, shell condition, and finish level. Here are realistic ranges:

Example: A 1,500 SF boutique retail space built out from vanilla shell at $100/SF = $150,000 total buildout cost.

What drives cost up in retail:

• Commercial kitchen equipment and hood systems (restaurants)
• Plumbing-intensive uses (salons, spas, medical)
• High-end finishes (custom millwork, stone, specialty lighting)
• ADA compliance upgrades
• Structural modifications (removing columns, raising ceilings)
• Fire suppression system upgrades

Before signing, have a contractor walk the space with you. A 30-minute site visit can reveal:

• The true shell condition vs. what the landlord described
• Existing plumbing and electrical locations
• HVAC capacity and condition
• Any structural limitations
• Potential code compliance issues

This information directly affects your buildout budget and your TI allowance negotiation. Don't sign without it.

Work with an architect or designer to produce:

• Floor plan showing your layout (sales floor, back of house, restrooms, storage)
• Reflected ceiling plan (lighting, HVAC registers, sprinklers)
• Elevations (storefront, feature walls, millwork)
• Mechanical, electrical, and plumbing plans

Landlord approval: Most leases require landlord approval of your plans before construction begins. Budget 2–4 weeks for this process.

Commercial tenant improvements in Los Angeles require permits from LADBS. The permit process for commercial work is more involved than residential:

• Building permit (structural and architectural)
• Electrical permit
• Plumbing permit (if adding or moving plumbing)
• Mechanical permit (HVAC modifications)
• Fire/sprinkler permit (if modifying fire suppression)
• Health department permit (restaurants and food service)

Commercial permit timelines in LA: Plan for 8–16 weeks for permit approval on a standard retail buildout. Restaurants and food service take longer due to health department review.

This is the most common reason retail buildouts run behind schedule. Start the permit process as early as possible — ideally before you sign the lease if the landlord allows it.

Once permits are in hand, construction begins. A typical retail buildout sequence:

1. Demo — Remove existing improvements not being reused
2. Rough framing — New interior walls, soffits, ceiling framing
3. Rough MEP — Plumbing, electrical, HVAC rough work; inspections
4. Insulation and drywall
5. Flooring — Concrete polishing, tile, LVP, carpet
6. Millwork and cabinetry — Display fixtures, checkout counter, shelving
7. Storefront and signage rough-in
8. Finish MEP — Fixtures, outlets, HVAC registers
9. Paint and finishes
10. Final inspections and Certificate of Occupancy

Before you can open for business, the city must issue a Certificate of Occupancy (C of O) confirming the space meets all code requirements. This requires passing all final inspections.

Do not open without a C of O. Operating without one can result in fines, forced closure, and insurance complications.

From lease signing to opening day:

• Simple cosmetic buildout: 6–10 weeks
• Standard retail buildout: 3–5 months
• Restaurant or complex buildout: 5–9 months

The permit timeline is the biggest variable. Experienced TI contractors know how to navigate the LA permitting process efficiently — this is one of the most valuable things a good contractor brings to a commercial project.

Not every contractor is equipped for commercial tenant improvement work. Look for:

Commercial experience: Ask specifically about retail TI projects. Residential contractors often underestimate the complexity of commercial code requirements, ADA compliance, and landlord coordination.

Permit expertise: Your contractor should handle all permit applications and have established relationships with LADBS plan checkers. Ask how many commercial permits they've pulled in the past year.

Subcontractor relationships: Commercial buildouts require licensed commercial electricians, plumbers, and HVAC contractors. Ask who they use and verify those subcontractors' licenses.

References from similar projects: Ask for references from retail clients with similar business types. A contractor who has built out 10 salons understands salon-specific requirements in a way a general contractor doesn't.

Signing the lease before getting a buildout estimate. Your buildout cost directly affects whether the deal makes financial sense. Get a contractor's assessment before you commit.

Underestimating the timeline. Most first-time retail tenants assume they'll be open in 60 days. In Los Angeles, with permitting, 4–6 months is more realistic for a standard buildout. Plan your lease start date accordingly.

Not reading the lease's TI provisions carefully. Some leases have strict requirements about who can do the work, what approvals are needed, and how the allowance is disbursed. Have an attorney review the TI provisions before signing.

Choosing the lowest bid. Commercial construction is not the place to cut corners. A contractor who can't navigate LA's commercial permitting process will cost you far more in delays than you saved on the bid.
