Commercial
Tenant improvements, office build-outs and ground-up commercial work across Los Angeles and Ventura Counties, scheduled around the reality that your business still has to operate.
Commercial construction runs on a different clock than residential work. There is a lease commencement date, a rent obligation that starts whether or not the space is ready, and usually a landlord whose approval is required before anything is touched. The constraint is rarely what to build. It is how to build it inside a fixed date and an occupied building.
The Oak Development delivers commercial projects across Los Angeles and Ventura Counties, including medical and professional offices, fitness facilities, restaurants and retail. We work to the same standard as our residential work, sequenced around business operating hours where the site requires it.
We are a licensed, bonded and insured California general contractor, license #1094201, and we can provide the certificates of insurance and documentation that landlords and property managers require before work starts.
Every project is scoped in writing before it begins. The items below are the elements we most commonly deliver on commercial construction projects.
Converting or upgrading leased space to suit an incoming tenant, from partial refits to full interior reconstruction.
Workstation areas, private offices, conference and huddle rooms, reception and break areas, delivered with the data and power infrastructure they need.
Build-outs with the additional planning that treatment and exam rooms require, including specialised plumbing, power and equipment coordination.
Front and back of house, including kitchen infrastructure, ventilation, grease management and the health department coordination the work involves.
Storefronts, display and fixture installation, lighting design and the accessibility compliance retail entrances have to meet.
Reinforced flooring assemblies, ventilation sized for occupancy load, and locker and shower facilities.
New commercial structures from site work and foundation through to finished shell and interior.
Accessible routes, restrooms, entrances and parking brought to current code as part of the scope rather than discovered at final inspection.
The same sequence on every project, so you always know what happens next and who is responsible for it.
We walk the space with you and, where relevant, your broker or landlord, and establish what the build requires and what the lease and building rules will allow.
Construction documents are developed and priced against a defined scope, so the number can be compared against a tenant improvement allowance line by line.
We work through landlord approval and building department plan check in parallel where possible, since these are usually the two things that determine whether the opening date holds.
Work is sequenced around the building's rules on hours, access, freight and noise, and around adjacent tenants who are still trading.
Building, fire and, where applicable, health department inspections are coordinated through to certificate of occupancy or final sign-off.
We hand over the completed space along with close-out documentation, warranties and as-built information.
Most commercial work we do happens in buildings that never fully close. Adjacent suites are occupied, there are rules about when noisy work can happen, freight elevator time has to be booked, and the parking structure cannot be blocked during business hours.
None of that changes what gets built. It changes how the schedule is constructed. Demolition and other high-noise work gets planned into permitted windows, deliveries are staged around building access rules, and the trades are sequenced so that a restricted window is never the thing that idles the whole crew.
The same applies to the approval path. Landlord approval and municipal plan check are frequently the longest items on a commercial schedule and they are largely outside a contractor's control. We start both as early as the drawings allow and keep you informed on where each one stands, because a date that depends on an approval nobody has chased is not a date.
The Oak Development is based in Calabasas and takes on commercial construction projects throughout Los Angeles and Ventura Counties, including:
Yes, and we price against a defined scope so the quote can be compared to the allowance line by line. Where the scope exceeds the allowance we identify that early rather than at the end, so you can make decisions while there is still time to adjust.
Yes. Many of our commercial projects involve evening or weekend work, either because the building requires it or because the tenant needs to keep trading. We plan those windows into the schedule from the start rather than treating them as an exception.
Yes. We prepare and submit the documentation both require and manage the process through approval. These two items are usually the longest lead on a commercial project, so we start them as early as the drawings allow.
We have completed medical buildings, gyms, restaurants and retail spaces, covering ground-up construction, tenant improvements, office build-outs and interior and exterior renovations across Los Angeles and Ventura Counties.
Yes. We are licensed, bonded and insured under California license #1094201 and can supply certificates of insurance naming the required additional insureds before work starts.
