Licensed electricians • Same-day service available • No obligation
Tenant improvement projects move fast and every trade on a TI job depends on the others staying on schedule. When the electrician falls behind on rough-in, the drywall crew waits. When rough-in isn’t inspected and approved on time, everything downstream shifts. When the final electrical trim-out runs long, the certificate of occupancy gets delayed and your tenant can’t open. The cost of a slow or disorganized electrical subcontractor on a TI project isn’t just an inconvenience. It’s real money lost by every party involved.
Saiyan Electric approaches tenant improvement electrical work with the same discipline that the best general contractors expect from their trade partners. We show up when we say we will. We complete rough-in on the schedule the project requires. We coordinate proactively with inspectors so approvals don’t become bottlenecks. And we communicate clearly with the GC and ownership throughout so everyone knows exactly where the electrical scope stands at every stage of the project.
Whether you’re a general contractor looking for a reliable electrical subcontractor, a property owner managing your own TI, or a business owner building out your first commercial space, Saiyan Electric delivers the professionalism and quality workmanship that keeps your project moving toward its opening date.
In older commercial buildings, what's in the walls doesn't always match what's on the as-built drawings if as-builts exist at all. We assess existing conditions before committing to a scope and communicate discrepancies early so the project team can adjust plans before they become problems mid-construction.
Many TI projects reveal that the space's existing electrical service isn't adequate for the new tenant's equipment and occupancy. We identify this during initial assessment and provide panel upgrade solutions that integrate cleanly with the overall TI scope and timeline.
TI electrical work happens alongside framing, plumbing, HVAC, and finish trades often in a compressed timeline. We coordinate our rough-in, inspection, and trim-out milestones with the GC's overall schedule so we're never the reason the project sits idle.
The electrical code requirements for a restaurant are different from those for a medical office, which are different from those for a retail store. We understand the specific requirements for each occupancy type and build them into the scope from the start so the inspector doesn't surface requirements mid-project that weren't planned for.
Tenant decisions change during construction. A wall moves. A piece of equipment gets added. The break room shifts to the other side of the building. We stay flexible and communicate the cost and schedule impact of changes clearly and promptly so everyone can make informed decisions without derailing the overall project.
Saiyan Electric provides complete electrical services for tenant improvement projects across all commercial space types.
We safely remove existing wiring, fixtures, devices, and panels that are no longer needed for the new tenant's layout, properly capping, labeling, and documenting everything that's being retained and everything that's being removed.
We run all new branch circuit wiring, conduit, and junction boxes per the approved electrical plans, working in coordination with framing and other rough-in trades to meet the inspection milestones the project schedule requires.
We add circuits to existing panels, install sub-panels, or perform full panel upgrades as required by the tenant's electrical load. All panel work is permitted, inspected, and coordinated with the utility when service upgrades are involved.
We install all lighting per the reflected ceiling plan recessed fixtures, track lighting, pendant fixtures, surface-mount fixtures, under-cabinet lighting, and any specialty lighting the tenant's design requires. We also handle dimmer installation, lighting controls, and integration with smart building systems.
We install all outlets, switches, dimmers, USB receptacles, dedicated circuits, and specialty devices per the electrical plans and any tenant-specific requirements, ensuring placement that's both code-compliant and practical for the tenant's actual use of the space.
We install code-required emergency lighting and exit signs throughout the tenant space, ensuring compliance with fire and building safety regulations before the certificate of occupancy is issued.
We provide conduit and rough-in infrastructure for data, communications, security, AV, and other low-voltage systems, coordinating with the low-voltage contractor or IT vendor who will complete the terminations and installations within that infrastructure.
We install all required GFCI and AFCI protection per current NEC requirements for the occupancy type: kitchens, bathrooms, wet locations, bedrooms in mixed-use spaces, and any other areas where arc fault or ground fault protection is required by code.
Here’s how we handle tenant improvement projects from planning with property managers and contractors to full system installation, delivering electrical setups tailored to each tenant’s needs.
We review the architectural and electrical plans, walk the existing space, assess current electrical conditions, and develop a detailed scope of work. We identify any discrepancies between plans and existing conditions early and communicate them to the project team before construction begins.
We prepare and submit the electrical permit application, respond to any plan check comments, and obtain permit approval before rough-in begins. We keep the GC and ownership informed of permit status throughout this process.
We complete all rough-in wiring, conduit, and box installation per the approved plans and coordinate the rough-in inspection with the city. We schedule inspections proactively to keep pace with the project schedule, not reactively after delays have already occurred.
We complete all above-ceiling conduit, wiring, and junction box work before ceiling grid or drywall closes, coordinating with the HVAC and low-voltage trades to avoid conflicts in shared ceiling and wall cavities.
As construction finishes, we install all devices, fixtures, cover plates, and panels, and make all final equipment connections. We coordinate trim-out timing with the GC to match the overall construction completion sequence.
We schedule and attend the final electrical inspection, address any correction items immediately, and provide the GC and ownership with documentation of final approval supporting the overall certificate of occupancy process so your tenant can open on time.
TI electrical costs vary considerably based on space size, occupancy type, existing electrical conditions, and the complexity of the tenant’s requirements. Here are typical ranges to help with budget planning:

“Tenant improvement projects are where electrical work gets real. You’re coordinating with other trades, working to someone else’s schedule, and delivering a finished product that a business owner is counting on to open their doors. We take that responsibility seriously and we’ve built our process around being the kind of electrical contractor that GCs call back on the next project.” — Owner, Saiyan Electric

As early as possible, ideally during pre-construction planning before permit submittal. Early electrical contractor involvement allows us to identify panel capacity issues, flag existing condition problems, and provide accurate pricing before construction begins. Last-minute electrical scoping leads to budget surprises and schedule pressure that’s avoidable with early coordination.
We can work from architectural plans with electrical notes for straightforward TI projects. For larger, more complex spaces or occupancies with specific engineering requirements like medical offices or industrial facilities, engineered electrical drawings provide the detail needed for accurate scoping and permit approval. We can advise on what level of drawing is appropriate for your project.
Most TI electrical work in Downey requires a building permit with an electrical sub-permit. The permit application requires a description of work and, depending on scope, electrical plans. We handle the entire permit process, including responding to any plan check comments that arise during review.
We plan work sequences carefully to isolate our work from live areas of the building. Work that requires touching shared electrical infrastructure like the main panel, shared feeders, or building common areas is scheduled during off-hours. We coordinate with the property manager and GC to ensure neighboring tenants are notified of any planned interruptions in advance.
This is one of the most common issues that surfaces during TI scoping. When we identify a capacity shortfall, we provide panel upgrade options as part of the overall TI scope including cost, timeline, and any utility coordination required. It’s always better to discover this before construction begins than after the tenant’s equipment is already on-site.
Yes. We provide documentation of the completed electrical work, including circuit schedules, panel labeling, and permit records. This documentation is valuable for the property owner, future tenants, and any subsequent electrical work performed in the space.
We provide conduit rough-in and infrastructure for low-voltage systems as part of the TI electrical scope. For the termination and installation of data, AV, and security systems themselves, we coordinate with the appropriate low-voltage contractor. If you need a referral to a trusted low-voltage partner, we’re happy to provide one.
The earlier you bring Saiyan Electric into your TI project, the smoother the electrical scope will go. Whether you're a general contractor putting together a bid, a property owner planning a buildout, or a business owner preparing to open a new location, we're ready to walk the space, review the plans, and give you a clear picture of the electrical scope and cost.
From the first plan review to the final inspection sign-off, Saiyan Electric delivers tenant improvement electrical work that keeps your project on schedule and your tenant ready to open. Let’s talk about your project.
