You signed the lease. The keys are in your hand, and your opening date is on the calendar. Then the plan reviewer asks for a load calculation, and the panel in your suite is half the size you need. That is how many electrical tenant buildouts in Houston go off track. The wiring is seldom the problem. The problem is that the big electrical questions get asked too late. This guide shows you what the work includes, what the city expects, and how to keep your opening date safe.

What Is an Electrical Tenant Buildout?

An electrical tenant buildout is the electrical work that turns a bare or outdated commercial space into one your business can use. It covers lighting, outlets, dedicated circuits for your equipment, and panels sized to your load. A licensed electrician installs it to code, pulls the permit, and passes inspection before you open.

What Does the Work Usually Include?

Every space is different, but most projects cover these items:

• Panels and sub-panels sized for your equipment and your future growth
• Lighting layout, controls, and exit and emergency lighting
• Outlets and dedicated circuits for ovens, medical devices, servers, or shop tools
• Wiring that follows the National Electrical Code and local rules
• Coordination with your general contractor, designer, and property manager

Restaurants, retail shops, medical offices, and industrial spaces all need different setups. A dental office needs clean power for its chairs. A restaurant needs heavy circuits for the kitchen. Tell your electrician what you plan to run before the drawings are final.

Does Your Space Have Enough Power?

Many tenants assume that "power is available" means "power is enough." It does not. A suite can have service and still fall short of what your business needs.

Before you sign, take these steps:

• Ask the landlord for the panel schedule and the amp rating of the service to your suite.
• Have an electrician walk the space and run a load calculation.
• Get the delivered capacity written into the lease.
• Ask who handles the work if the building needs a bigger service. Base building upgrades often fall to the landlord, while circuits made just for your business usually fall to you. Your lease decides.

If the numbers come up short, you want to learn that during lease talks, not after the walls are closed.
