    About Tenant Finish & Build-Outs

    Tenant finish electrical is a project-management job as much as an electrical one. Landlord requirements, building department reviews, inspector schedules, HVAC and plumbing coordination, and your own equipment vendors all have to line up so the space is ready for occupancy on the date you told your customers.

    We work with restaurants, retail storefronts, offices, medical and dental suites, salons, coffee shops, and light-industrial tenants across Franklin County and Greater St. Louis. Typical scope: distribution panel, lighting layout, receptacle plan, emergency and egress lighting, exit signs, equipment circuits (walk-ins, ovens, autoclaves, servers, dental chairs), and low-voltage rough-in for data, POS, and A/V.

    We'll work directly with your general contractor or run the electrical scope directly for you if you're managing the build. Either way, we own the electrical timeline and communicate proactively when anything on our side would affect your open date.

    Frequently Asked Questions

    Do you work directly with landlords or only through GCs?+

    Both. We often work directly with tenants who are managing their own build, and we're a regular sub for GCs handling tenant improvements. Either way we'll coordinate with the landlord's requirements.

    Can you handle restaurant equipment hookups?+

    Yes — walk-in coolers, hood systems, ovens, dishwashers, fryers, and refrigeration are all standard scope for us. We coordinate hookup with your equipment vendor's install schedule.

    What about medical or dental suites?+

    Yes. Dedicated equipment circuits, isolated ground receptacles where required, and coordination with medical/dental equipment vendors are all part of the scope.

    How far ahead should I schedule?+

    Ideally 4–6 weeks before your target rough-in date so we can review plans, verify the shell service, and lock in inspector timing.

    Do you install emergency lighting and exit signs?+

    Yes — egress lighting, exit signs, emergency circuits, and any life-safety items required by your local code and your occupancy type.
