Commercial Construction
Lee & Company Construction takes on commercial construction and tenant improvements for business owners, property owners, and developers across Southern California. From interior build-outs to full commercial remodels, we coordinate the planning, the permitting, the construction, and the handover, and what we hand over is a space built for the way a business actually runs. Whether you are opening a new location, upgrading one you already have, or preparing a property for an incoming tenant, you get practical field experience, clear communication, and one team keeping oversight of the job from start to finish.
- 01
Walk-through & scope
We walk the space with you, and with building management where there is a lease, so the scope matches what your landlord and the city will both sign off on.
- 02
Plans, permits & ADA review
We coordinate drawings and city submittal, including the accessibility upgrades a commercial permit usually triggers: path of travel, restrooms, door clearances, ramps, and signage.
- 03
Build-out
Demolition, framing, electrical, plumbing, HVAC, ceilings, and flooring, sequenced so the trades follow each other cleanly and the schedule holds to your opening date.
- 04
Staying open while we work
If you are trading through the job, we phase it around your hours and keep the work area sealed and clean, so your customers see a business that is open rather than a building site.
- 05
Final inspections & turnover
Finishes, fixtures, signage coordination, and the final inspections and sign-offs you need before you can open the doors.

Office & Retail Build-Outs
Suites, private offices, conference rooms, reception areas, storefronts, and showrooms, built around how your team and your customers actually use the space.
Commercial Remodeling
Layout changes, finishes, restrooms, ceilings, flooring, and lighting, upgraded without keeping you closed any longer than the work honestly needs.
Ground-Up Commercial Construction
New commercial buildings taken from site preparation all the way through to completion and final sign-off.
Additions & Expansions
Expanding the building you are already in, with the layout planning and structural coordination that an addition on a working site demands.
ADA Compliance Upgrades
Restroom updates, path of travel corrections, door clearances, ramps, and signage, handled as part of the permit rather than as a surprise at final inspection.
