Base-building work for owners: renovation of existing commercial and mixed-use buildings, major repairs and upgrades to common areas and systems. We plan the work around tenants, residents and the building's ongoing use.
Tell us about the project and a project manager will follow up.
What sets the plan, the estimate and the schedule for this kind of project.
We plan work around tenants, residents and deliveries, with protection of occupied areas.
Regular written updates and budget and change-order tracking give owners and lenders a clear view.
Structural and envelope work follows an engineer's design and the permit, with inspections at each stage.

Building-level work is different from a tenant improvement. It involves systems that serve every tenant, structure that carries the whole building and common areas everyone uses. The work is phased around the people in the building, and an owner usually has lenders, tenants and the city all watching the schedule.
We work from your architect and engineer's drawings, price the scope in writing, and phase construction to keep the building running where it can.

Building-level work usually needs a permit and engineering, and the scope can trigger accessibility and life-safety upgrades beyond the area you are renovating. Older commercial buildings may also be screened for historic significance, which affects exterior and street-facing work.
Seismic and structural upgrade scopes, and repair of fire, water or foundation damage, are evaluated on request. Bring the building, any engineer's report and the problem you are trying to solve, and we will tell you the next step.
See the full process page for what you receive at each step.
We walk the building with you, review engineer findings and drawings, and put a written estimate in your hands, with assumptions stated.
We coordinate with your architect and engineer and run permits through SF DBI and Planning, and phase the work around occupants.
Regular walkthroughs and written updates during the build, punch-list resolution before final payment, and a closeout package.
Commercial Building Renovation & Repair come up in many San Francisco neighborhoods. These pages cover housing stock, permits and typical projects in each area. We work in every neighborhood in the city, listed or not.

Other commercial work
Commercial work runs on leases, landlord approvals and fixed dates. See the other build types we take on, or the commercial overview.
Anything else, ask in the form at the top of the page.
Often, with phasing, protection and agreed hours. We plan the sequence around tenants and residents and call out the points where services are interrupted.
Yes. Mixed-use projects involve both commercial and residential rules and occupants, which we plan around.
Structural and seismic scopes are evaluated on request, project by project. Tell us what the engineer has recommended and we will tell you the next step.
We provide regular written updates and budget and change-order tracking during construction.
