An office build-out in LA costs 150 to 250 dollars per sqft. A 3000 sqft office runs 450K to 750K. Open floor plans cost less than private offices due to fewer walls and doors.
Open plan: 100-150 sqft per workstation (desk + chair + circulation). Private offices: 120-200 sqft each. Conference rooms: 25 sqft per seat. Break room/kitchen: 200-400 sqft. Reception: 150-300 sqft. Server/IT room: 50-100 sqft. Restrooms: per code based on occupancy. Plan for 20% growth — you'll fill the space faster than expected.
Activity-based design: different zones for different work types (focus, collaborate, socialize). Phone booths ($3K-$8K each): small enclosed spaces for calls and video meetings. Wellness rooms: quiet space for meditation, nursing mothers, or decompression. Biophilic design: plants, natural materials, maximized daylight. These features attract and retain talent.
HVAC: modify existing building system or add supplemental units. Budget: $15-$30/sqft. Electrical: power and data to every workstation, server room dedicated circuit, LED lighting with controls. Budget: $10-$20/sqft. Plumbing: break room sink, restroom modifications if needed. Budget: $5-$10/sqft.
Required for all commercial spaces. Key requirements: 36-inch minimum door widths, accessible restroom (60-inch turning radius), accessible route throughout the office (no steps without ramp), counters at 34-inch maximum height, visible fire alarms in addition to audible. Non-compliance = failed LADBS final inspection + potential ADA lawsuits.
Design: 2-4 weeks. LADBS plan check: 4-8 weeks. Construction: 6-12 weeks depending on scope. Total: 3-6 months from lease signing to move-in. Pro tip: start design during lease negotiation, submit to LADBS on lease signing date, begin construction when permits are issued. This overlapping approach saves 4-8 weeks.
