California Commercial Tenant Improvement.
Commercial TI across LA — office, retail, restaurant, light industrial. We work with tenant architects or recommend our regulars. LADBS commercial permit track, MEP/T-24/ADA scope built in.
Bay Area TI — SF, Oakland, Peninsula office and retail. Code compliance, accessibility, and seismic considerations on every project.

How we think about commercial tenant improvement.
Commercial TI lives or dies on schedule. Every day past handover is rent collected at zero or paid at full. We sequence to the closing date, not the construction-comfort date. That means stocked materials before demo starts, off-hours utility cuts, and weekend inspections where the city allows.
ADA + Title 24 non-residential compliance are where most landlords get blindsided. A $40K painting + flooring scope can trigger $120K of bathroom + parking ADA upgrades under the 20% rule. We pull the disabled-access checklist before signing any TI contract — every time.
The schedule, written out.
Week 0
LOI to lease execution
Test-fit + cost certainty for tenant + landlord negotiation.
Week 1–4
Design + permit set
Architectural, MEP, ADA, structural where needed; building department intake.
Week 4–10
Plan check + procurement
City review, long-lead orders (electrical gear, HVAC RTUs).
Week 10–14
Demo + rough
Demo, framing, MEP rough, fire-sprinkler relocation, ceiling grid.
Week 14–18
Finish + close-out
Drywall, paint, flooring, fixtures, signage, final inspections, CofO.
Materials & assemblies.
| Component | Default spec | Why |
|---|---|---|
| Ceilings | Acoustic tile (NRC ≥ 0.70) on 15/16" grid, or open-plenum painted black with acoustic clouds | Open plenum saves vertical but doubles paint cost. |
| Flooring | LVT (10 mil+ wear layer), polished concrete, or carpet tile | LVT is the workhorse — 15-year warranty, swappable. |
| Lighting | LED 2x4 troffers + dimmable controls + occupancy sensors (T-24) | T-24 controls are no longer optional on commercial. |
| HVAC | Rooftop unit (RTU) sized per ASHRAE 62.1, demand-controlled ventilation | DCV pays back via reduced makeup air during low occupancy. |
| Restrooms | ADA-compliant fixtures, grab bars at correct heights, accessible route, signage | Every fixture must hit exact heights — the inspector measures. |
Hidden costs we flag up front.
| Line item | Range | When it hits |
|---|---|---|
| ADA path-of-travel upgrades (20% rule) | $15K–$120K | TI cost triggers proportional accessibility upgrades |
| Fire-sprinkler reconfiguration | $6K–$40K | new walls cross existing sprinkler heads |
| Electrical gear lead time | 20–40 wk lead | new switchgear or large transformer |
| Title 24 lighting controls | $3K–$18K | old fluorescent retrofit triggers full controls upgrade |
cheaper alternatives
What we'd consider — and what we wouldn't.
As-is leasing (no TI)
Cheaper for landlord but extends vacancy and lowers achievable rent.
Build-to-suit with allowance + overage
Best alignment when tenant credit + lease term support amortization.
pitfalls — takeover-job patterns
Mistakes to avoid.
- Signing a TI contract before the ADA path-of-travel cost is known
- Ordering electrical gear after permit — 30+ week lead times now standard, kills the schedule
- Demoing before fire-sprinkler shop drawings are approved — re-pipe ends up rushed
- Assuming the existing CofO covers the new use — change of occupancy almost always triggers new compliance

In short.
- What does LA office TI cost?
- $80–$180/sqft typical for mid-tier office. Restaurant buildouts $200–$280/sqft.
- How long does an LA TI take?
- 2–6 months. Restaurants on the longer side because of hood + grease trap.
- Bay Area TI cost?
- $110–$280/sqft office; $250–$380/sqft restaurant.
- Does SF TI trigger seismic upgrades?
- On older buildings, often yes — path-of-travel + parapet bracing common.
