Tenant Improvement Electrical in Santa Rosa, CA
Tenant improvement electrical is the electrical scope required to adapt a leased commercial space for a specific tenant's use — new circuits, dedicated equipment lines, lighting design, panel or subpanel work, and low-voltage rough-in for data and communications. J&J Electric handles TI electrical work throughout Santa Rosa for property managers, general contractors, and business tenants, and we document scope and payment responsibility in writing before work starts, not after.
- We'll tell you plainly who typically pays for what. Panel upgrades in particular are often a landlord-funded item even when the rest of the scope is tenant-funded — we'll help you understand what your lease's work letter actually says.
- “Just changing some lights” can still trigger Title 24 compliance. California's lighting energy code applies to TI alterations inside existing buildings, not just new construction — we'll flag it before it becomes a failed inspection.
- We schedule around your operations, not the other way around. After-hours, weekends, or planned downtime for disruptive work — so your business, and your neighbors' businesses, keep running.

What Is Tenant Improvement Electrical?
Tenant improvement electrical is the electrical work needed to adapt a leased commercial space for a specific tenant's use, including new circuits, dedicated equipment lines, outlet placement, lighting design and fixtures, panel or subpanel work sized to the space, and low-voltage rough-in for data and communications. The scope varies significantly by tenant type: an office suite needs outlet density and lighting controls; a restaurant needs dedicated, often higher-amperage circuits for kitchen equipment; a medical office needs isolated grounding and backup power; a retail tenant needs display lighting and point-of-sale circuits.
This work matters for property managers, general contractors, and tenants alike, because the building's existing electrical infrastructure sets the ceiling on what's possible. A space with an undersized panel or a service entrance already near capacity may need a panel upgrade before any tenant-specific work can even start — a different budget line and permit process than the interior build-out itself, and often the single biggest source of confusion in a TI project.
Our Tenant Improvement Electrical Process
Here's how we typically scope and execute a TI electrical project:
- Site Visit & Load Assessment — We see the existing panel, understand the current load profile, and review the space in person — a quote without a site visit is an estimate, not a scope.
- Scope & Payment Documentation — We put the electrical scope and payment responsibility in writing, including who's responsible for any panel or service upgrade, before work starts.
- Permit Coordination — We pull the required electrical permit and confirm Title 24 lighting compliance where applicable, even for alterations inside your existing space.
- Build — We sequence the work correctly — any building-level panel or service upgrade is inspected and approved before interior TI work proceeds on top of it — and schedule disruptive work to minimize impact on your operations and neighboring tenants.
- Final Inspection & Documentation — We coordinate final inspection and provide itemized, documented invoicing suitable for TI allowance reimbursement submissions.
How Much Does Tenant Improvement Electrical Cost?
TI electrical costs vary enormously by tenant type, existing infrastructure, and scope .A simple office suite fit-out on adequate existing electrical infrastructure is a modest project; a restaurant build-out requiring a panel upgrade first is considerably larger.
A few things move the cost more than anything else:
- Tenant type. A restaurant or medical office needs meaningfully more specialized electrical scope than a standard office suite.
- Whether a panel or service upgrade is needed. If the building's existing infrastructure can't support your load, that's a separate, often larger budget line.
- Your tenant improvement allowance. How much of the electrical scope your TIA covers, versus what falls to you directly, depends on your lease's work letter.
- Equipment specifications. Restaurant, medical, or manufacturing equipment amperage and voltage requirements can shift the electrical design and cost if finalized after the initial quote.

Who Actually Pays: Landlord, Tenant, or the TI Allowance?
Payment responsibility for TI electrical work is determined by your lease's work letter, not by any default rule. Most commercial leases include a tenant improvement allowance (TIA) — a dollar amount, often quoted per square foot, that the landlord contributes toward the build-out. Whether electrical work is covered by that allowance, billed separately, or split between landlord and tenant depends entirely on what the work letter specifies.
Panel upgrades are the most common point of dispute. Because a panel upgrade adds long-term value to the building and typically outlasts any single tenant, it's frequently negotiated as landlord-funded or landlord-shared, even when the rest of the electrical scope is tenant-funded. The cleanest approach is defining this in writing in the work letter before signing — we can provide a written electrical scope early enough to inform that negotiation, rather than after the lease is already final.

FAQ
Frequently Asked Questions
Who pays for tenant improvement electrical work, the landlord or the tenant?
Payment responsibility is determined by the lease's work letter, not by any default rule. Most commercial leases include a tenant improvement allowance, and whether electrical work is covered by that allowance, billed separately, or split between landlord and tenant depends entirely on what the work letter specifies.
What is a tenant improvement allowance?
A tenant improvement allowance (TIA) is a dollar amount, usually quoted per square foot, that a landlord contributes toward building out a leased space. It typically covers permanent improvements like walls, flooring, HVAC modifications, and electrical work.
Does tenant improvement electrical work require a permit in California?
Yes. TI electrical work requires a permit and inspection from the local building department whenever it involves new circuits, new wiring, or changes to the distribution system, regardless of how small the space or scope seems.
Can a landlord be held liable for electrical work they didn't hire the contractor for?
Potentially, yes. Under California's mechanics lien law, an unpaid contractor or subcontractor can record a lien against the property where tenant-authorized work happened, even if the landlord never signed the contract. A landlord can protect against this with a Notice of Nonresponsibility under California Civil Code § 8444, which must be posted and recorded within 10 days of learning about the work.
Does Title 24 apply to tenant improvement projects, or only new construction?
Title 24 applies to TI projects inside existing buildings, not just new construction. California's Building Energy Efficiency Standards govern lighting power density and controls, and alterations that modify lighting circuits trigger compliance even when the rest of the building shell is untouched.
Who is responsible for a panel upgrade during a TI project?
It's determined by what the lease's work letter specifies. Because panel upgrades add long-term value to the building, they're frequently negotiated as landlord-funded or landlord-shared, but that split needs to be stated explicitly rather than assumed.
How long does a TI electrical build-out typically take?
It depends heavily on scope. A single-suite office fit-out on adequate existing electrical infrastructure might take days to a couple of weeks, while a project that also requires a panel or service upgrade will take longer, since that upstream work generally needs to be inspected and approved first.
What should I ask before hiring a commercial electrician for a TI project?
Ask for a realistic timeline that accounts for permitting, inspections, and material lead times. Ask which parts of the work involve subcontractors, and confirm they're properly licensed and insured. Ask about warranty terms, and confirm whether the contractor can work after-hours or weekends without disrupting your operations.
How is TI electrical work different for a restaurant vs. an office tenant?
A restaurant typically needs dedicated, often higher-amperage circuits for kitchen equipment, while an office tenant generally needs outlet density, lighting controls, and possibly a server closet circuit. The scopes aren't interchangeable.
Can you work around our other tenants and avoid disrupting their businesses?
Yes. We isolate affected circuits and schedule disruptive work — panel swaps, main feeder changes, significant circuit additions — for after-hours, weekends, or planned downtime, coordinated directly with your property manager.
