Commercial Construction in Los Angeles

What does commercial construction actually cost in LA in 2026?

Commercial construction and tenant improvements in Los Angeles cost $40 to $950 per square foot in 2026 depending on project type. Office build-outs run $50-$150/sqft, retail and showroom $75-$200, restaurant and bar $200-$500, and medical office $375-$950. LADBS commercial plan check averages 2 to 3 months for full tenant improvements. Title 24 2026 standards require heat pump expansion for commercial HVAC, ASHRAE Guideline 36 controls, enhanced indoor air quality ventilation, and electric-ready commercial kitchens. California ADA standards exceed federal (2 accessible parking spaces per 25 vs 1 per 25; 96-inch van aisles vs 60-inch federal). NP Line Design (CSLB #1105249) provides design-build commercial construction with LADBS permit management, Title 24 compliance, and ADA accessibility under one contract.

How does the process work?

1. 01

3. 03
   LADBS permit management via ePlanLA - express, counter, expanded counter, or full plan check (same-day to 3 months)
4. 04
   Multi-trade construction coordination (electrical, plumbing, HVAC, fire, data/low-voltage) with daily construction management
5. 05
   LADBS final inspection and Certificate of Occupancy, post-construction warranty and maintenance guide

What drives the price?

• ·Office build-out: $50-$150/sqft

• ·Restaurant/bar: $200-$500/sqft (kitchen equipment 40-70% of budget)
• ·Medical (primary care): $375-$500/sqft; specialty/surgery $500-$950
• ·Warehouse-to-office conversion: $75-$200/sqft plus seismic retrofit 20-30% of budget
• ·Industrial/warehouse TI: $40-$100/sqft
• ·HVAC $35-$60/sqft, electrical $6-$34/sqft on typical commercial

What LA rules actually apply?

Specific LADBS, Title 24, and California code citations — not generic advice.

• LADBS commercial plan check averages 2-3 months for full TI via ePlanLA digital submission (paper phased out 2025)
• Express permits same-day for minor alterations/MEP only ($150-$500); counter plan check 1-2 weeks for simple TI ($500-$2,000)
• Title 24 2026 (effective Jan 1, 2026): heat pump expansion for end-of-life rooftop units, ASHRAE Guideline 36 controls, enhanced IAQ ventilation, electric-ready kitchens - non-compliance $500-$2,000/day/violation
• California ADA: 2 accessible parking spaces per 25 (vs 1 per 25 federal), 96-inch van aisles (vs 60-inch federal)
• Restaurants require Type I hood system, grease interceptor, LA County Health Dept plan check, fire suppression
• Medical offices require medical gas $15K-$25K per treatment room, positive/negative pressure HVAC, lead-lined walls for radiology, HCAI compliance if hospital-associated
• Plan check fees 65-80% of permit fee on top of base application cost

What do homeowners miss that costs them money?

• ⚠Kitchen equipment represents 40-70% of restaurant build-out budget - value engineering must happen before design lock
• ⚠Warehouse-to-office conversions trigger seismic retrofit adding 20-30% to budget; 1,500+ LA County warehouses fit this profile
• ⚠Medical office infection control during construction is a separate scope with negative-pressure containment, not a line item to compress
• ⚠Inadequate drawings, unresolved structural issues, ADA violations, missing Title 24 calcs, and incomplete fire/life safety plans are the top five plan check rejection causes
• ⚠Restaurants and medical offices are highly variable by equipment scope - early equipment selection drives entire MEP design

How long will it take?

Industrial/warehouse TI 4-8 weeks. Office build-out 6-12 weeks. Retail/showroom 6-12 weeks. Restaurant/bar 12-24 weeks. Medical primary care 16-30 weeks. Medical specialty/surgery 24-40 weeks. Add 2-3 months for LADBS plan check on full commercial TI.

Questions LA homeowners actually ask

• What does a commercial construction project cost in Los Angeles in 2026?

  For a well-scoped project, $100K–$2.0M is the realistic LA range we see across NP Line Design's active book. Baily narrows that to your specific neighborhood, lot, and scope inside the chat — typically in 3–5 questions.

• How long does commercial construction usually take?

  12–50 weeks on site for a typical LA project, not counting permit and design phases. Baily gives you a phase-by-phase timeline from scope lock to final inspection.

• Are permits required?

  Almost always — LADBS has jurisdiction across most of Los Angeles. Baily flags the exact permits your scope needs (structural, electrical, plumbing, T24 energy), the review path (standard plan-check vs. express), and realistic LADBS timelines.

• Can Baily handle Title 24, HPOZ, hillside, or coastal commission rules?

  Yes — that's the whole point of an LA-native AI. Baily knows Title 24 energy compliance, HPOZ preservation rules for historic zones, the hillside ordinance, and the coastal commission permit path. Tell Baily your ZIP and lot and it flags what applies.

• Who actually builds my project?

  NP Line Design — a licensed LA general contractor (CSLB #1105249, BBB A+) and the team that built Baily. One builder, not a lead pool. You'll speak with Netanel Presman (RMO) directly once your scope is locked.
