Commercial tenant improvements across California: the Bay Area, Los Angeles, Orange County, San Diego and Sacramento
About California Tenant Improvement
We build out leased commercial space across California, with one team responsible for design coordination, permits, every trade and closeout.
Focused on tenant improvements
Tenant improvements are different from ground-up construction. They happen inside occupied buildings, on lease-driven schedules, with landlords, property managers and neighbors to respect. That is the work we focus on: offices, medical and dental practices, retail stores, restaurants, warehouses, hospitality spaces and schools.
How we work
- Walk the space with you before you commit.
- Give you a clear, written, trade-by-trade estimate.
- Run permits and inspections with the right local agency.
- Keep you and your landlord informed every week.
- Close out with complete documents, warranties and allowance paperwork.
