Tenant Improvement & Commercial Build-Out Electrical Wiring in Fort Worth, TX

Tenant improvement electrical wiring also called commercial build-out or finish-out electrical work is the installation, rerouting, and upgrading of electrical systems in a leased commercial space to meet the specific operational needs of the incoming tenant.

It transforms a raw shell space, a second-generation space left by a prior tenant, or an existing space being repurposed into a fully functional, code-compliant environment with the right outlets in the right locations, lighting designed for the specific use, properly sized circuits for the actual equipment, and a panel that can support the total electrical load of the business.

For Fort Worth businesses leasing commercial space, offices, retail stores, restaurants, daycares, medical practices, salons, etc... the electrical build-out is one of the highest-stakes components of the project. Done right and on schedule, it puts you in business on time. Done wrong or late, it delays your opening, triggers permit corrections, and costs significantly more to fix than it would have cost to do correctly the first time.

S&M Electric handles tenant improvement electrical wiring for businesses from West Fort Worth to Weatherford coordinated with your general contractor, permitted through the City of Fort Worth, and installed to NEC commercial standards.

Why Electrical Is the Most Critical Trade in a

Commercial Build-Out

Every other trade in a commercial build-out has flexibility. Walls can be moved. Flooring can be replaced. Paint can be redone.

Electrical cannot be easily undone after walls are closed. The decisions made at rough-in; where circuits go, how they're sized, where the panel is located, how much capacity is built in, define the operational capability of the space for the entire lease term.

The Rough-In Window Is the Only Efficient Time to Build It Right

When walls are open and ceilings are exposed, adding circuits costs a fraction of what they cost after drywall is installed. A business that opens with insufficient outlets or undersized circuits pays for every addition at finished-wall rates, cutting open, patching, repainting rather than rough-in rates.

Electrical Delays Are Project-Ending Delays

The City of Fort Worth requires a rough-in electrical inspection before walls can be closed. If the electrical rough-in fails inspection for wrong wire gauge, missing conduit, incorrect circuit sizing, missing GFCI protection, etc... the inspection has to be rescheduled. That delay cascades through every downstream trade: drywall, ceiling, flooring, millwork. A single failed electrical inspection can push an opening date back by weeks.

The Electrical Budget Often Gets Underestimated

Commercial build-out electrical work in Fort Worth typically runs $8 to $25 per square foot depending on the complexity of the space and its electrical requirements. A restaurant or commercial kitchen is at the high end. A simple office or retail space is at the lower end. Most project budgets that blow out on electrical do so because the electrical scope was estimated before the equipment list was finalized — and the actual load was significantly higher than assumed.

What S&M Electric Handles in a Commercial Build-Out

Pre-Construction Electrical Planning

Before a wire is pulled or a permit is submitted, we review your space layout, your equipment list, and your operational requirements. We then create a load calculation and electrical plan that sizes every circuit correctly for what you're actually putting in the space. This prevents the most common and most expensive build-out electrical mistake: discovering mid-project that the panel can't support the load.

Panel Assessment and Upgrade Coordination

In second-generation spaces and older Fort Worth commercial buildings, the existing panel is often undersized for a new tenant's electrical demands, particularly for restaurants, medical practices, daycares with commercial HVAC, or any business with significant equipment loads. We assess the existing panel before the project starts and identify upgrade requirements that need to be budgeted and permitted as part of the build-out.

Electrical Rough-In

The rough-in phase is completed before walls are closed and includes running all conduit, pulling all wire, installing all boxes, and connecting all circuits to the panel. This is where the entire electrical infrastructure of the space is built. We coordinate the rough-in schedule with your general contractor to ensure the electrical inspection is ready when it needs to be not after the project schedule has already slipped.

Fort Worth Permit Coordination

Commercial tenant improvement projects in Fort Worth require electrical permits from the City of Fort Worth Development Services Department. The building permit must be issued before permits can be applied for. Fort Worth commercial permit review typically runs 2 to 4 weeks for standard tenant improvement projects. We submit permit applications with complete, correction-ready documentation to minimize review time and avoid the corrections that add weeks to the process.

Specialty Circuit Installation

Different business types have different specialty electrical requirements:

Restaurants and commercial kitchens — dedicated circuits for commercial ovens, fryers, refrigeration, walk-in coolers, hood systems, and dishwashers; all properly sized for commercial kitchen load profiles
Daycares and schools — circuits for HVAC, commercial kitchen or break room equipment, security systems, and emergency lighting in compliance with Texas childcare facility requirements
Medical and dental offices — isolated ground circuits for sensitive equipment, dedicated circuits for X-ray and imaging systems, emergency lighting and backup power considerations
Retail spaces — flexible outlet placement for display fixtures, POS systems, and security equipment; lighting circuits for retail-specific fixtures and controls
Office spaces — dedicated circuits for server rooms or data closets, conference room AV systems, kitchen equipment, and workstation power density

Lighting Installation

Commercial lighting in a build-out involves more than putting fixtures in ceilings. We install lighting circuits matched to the lighting design whether that's LED troffers in an office, track lighting on a retail floor, code-required task lighting in a commercial kitchen, or emergency egress lighting required by occupancy classification.

Final Trim and Testing

After walls and ceilings are closed, we install all devices; outlets, switches, cover plates, breakers, etc... and test every circuit before the final electrical inspection. We coordinate the final inspection with the City of Fort Worth and address any required corrections before your certificate of occupancy process begins.

The Hidden Electrical Costs in DFW

Tenant Improvement Projects

The Fort Worth commercial real estate market has specific conditions that create electrical budget surprises for tenants who don't do their due diligence before signing a lease:

Federal Pacific and Zinsco Panels

Many older DFW commercial buildings, particularly those built in the 1960s through 1980s still contain Federal Pacific or Zinsco electrical panels with documented failure rates. When discovered during the permit process, Fort Worth inspectors require panel replacement as a condition of approval. Cost: $3,000 to $8,000 plus code-required grounding upgrades. This is a landlord-responsibility question that needs to be negotiated before lease signing, not discovered after permits are submitted.

Aluminum Branch Circuit Wiring

DFW's 1980s commercial construction boom produced thousands of spaces wired with aluminum branch circuits. Aluminum wiring remediation is required before new electrical work can safely extend from or connect to existing aluminum circuits. Identify this before the build-out budget is finalized.

Insufficient Existing Service Capacity

A second-generation space leased from a prior tenant with lighter electrical demands may have a panel that cannot support your operation. A restaurant moving into a former office space, or a salon moving into a former retail space, almost always needs a panel upgrade and that upgrade requires Oncor coordination that adds lead time to the project.

Change of Use Permitting

Converting a space from one occupancy classification to another (IE: retail to restaurant, office to medical, storage to daycare,etc...) triggers a change-of-use permit that requires the electrical system to meet the code requirements of the new occupancy, not just the old one. This can include emergency lighting, additional GFCI protection, dedicated circuits for new equipment classes, and fire alarm integration.

Working With Your General Contractor

Commercial build-out electrical work requires tight coordination with the general contractor managing the project.

The typical electrical coordination sequence:

Pre-construction — Electrical plan review, load calculation, panel assessment, permit application submission
Demo and framing — Electrician on-site during framing to confirm box locations before walls go up
Rough-in — All conduit, wire, and boxes installed; rough-in inspection scheduled
Rough-in inspection — City of Fort Worth electrical inspector; walls cannot close until this passes
Mechanical and insulation coordination — Electrical must coordinate with HVAC ductwork before ceilings close
Trim-out — Devices, fixtures, breakers installed after drywall and paint
Final inspection — All circuits tested; certificate of occupancy process begins

We communicate directly with your GC throughout the project providing inspection-ready work on schedule and flagging any conditions that affect the project timeline before they become delays.

Tenant Improvement Electrical FAQs — Answered Straight

How much does commercial build-out electrical wiring cost in Fort Worth?

Tenant improvement electrical wiring in Fort Worth typically runs $8 to $25 per square foot for the electrical scope alone not including the panel upgrade if one is required. A 2,000 square foot office build-out might run $16,000 to $30,000 in electrical. A restaurant build-out of the same size with commercial kitchen circuits, hood system power, walk-in refrigeration, and dedicated equipment circuits, runs significantly higher. We provide a specific written proposal after reviewing your space, equipment list, and layout. National cost averages are not reliable for DFW commercial projects.

How long does the electrical permit process take in Fort Worth?

A Fort Worth commercial electrical permit review averages 2 to 4 weeks for standard tenant improvement projects. Projects requiring change-of-use review, fire department sign-off, or more complex documentation take longer. Permit applications with incomplete or incorrect documentation are returned for correction adding additional weeks. We submit correction-ready permit packages to avoid this delay.

Who is responsible for the electrical build-out — the landlord or the tenant?

In most Fort Worth commercial leases, the landlord provides a base building electrical service to the space with a panel of a certain amperage at a specific location. Everything within the leased space, the circuits, outlets, lighting, specialty equipment wiring is the tenant's responsibility, funded either out of pocket or through a tenant improvement allowance (TIA) negotiated in the lease. If the base building panel is inadequate for your operation, that's a negotiation point with the landlord before signing, not a surprise after you've committed to the space.

What is a tenant improvement allowance and how does it affect the electrical budget?

A tenant improvement allowance (TIA) is a dollar contribution from the landlord toward build-out costs typically expressed as a per-square-foot amount. In Fort Worth currently, TIA rates for office and retail space commonly range from $20 to $50 per square foot. For most businesses, the TIA covers a portion of the total build-out cost; tenants fund the gap. The electrical scope should be fully estimated before the TIA is negotiated, so you know how much of the allowance is consumed by electrical alone and how much remains for other build-out elements.

Do I need a separate electrical permit for a tenant improvement in Fort Worth?

Yes. The City of Fort Worth requires individual trade permits including an electrical permit for commercial tenant improvement projects. The building permit must be issued first; trade permits are applied for after the building permit is in place. We handle the electrical permit application as part of the project; you don't navigate the Fort Worth Development Services Department on your own.

What happens if the electrical rough-in fails inspection?

A failed rough-in inspection stops wall closure until the deficiencies are corrected and a re-inspection is scheduled. Common failure reasons include wrong wire gauge, incorrect conduit type, missing GFCI protection in required locations, insufficient neutral wire in multi-wire circuits, and improper box installation. Each re-inspection adds time to the schedule which delays every downstream trade. We submit rough-in work that passes inspection the first time.

How early should I involve an electrician in a commercial build-out?

Before you sign the lease ideally. An electrician who reviews the space before lease execution can identify existing electrical conditions (panel capacity, wiring type, available service) that affect your build-out budget and timeline. Discovering that the space needs a $15,000 panel upgrade after signing a five-year lease is a fundamentally different situation than knowing it during lease negotiation and pricing it into the deal or requiring the landlord to address it as a lease condition.

The Right Electrical Build-Out Opens Your Business on Time.

A build-out that passes rough-in inspection the first time. Walls that close on schedule. A space that's wired for what your business actually needs, not what the last tenant needed. That's what S&M Electric delivers on every tenant improvement project.
