Commercial Interior Renovation

Wiring Your Renovation

for Code, Function, and the Future

When your commercial space undergoes an interior renovation, whether it’s a minor refresh or a full gut, your electrical system needs to evolve too. From moving outlets and lighting to completely rewiring for new layouts, Bierlein-Trombley Electric is your trusted partner in getting it done safely, cleanly, and to code.

We work with business owners, property managers, general contractors, and tenants across Mid-Michigan and Traverse City to deliver reliable, well-planned electrical solutions for all types of interior commercial renovations.

When Do You Need an Electrician for a Renovation?

Most interior renovations affect electrical systems in some way. You may need us if you’re:

Adding or relocating outlets or switches
Installing new lighting or controls
Creating new offices or reworking open spaces
Replacing or upgrading panel space
Running new dedicated circuits for equipment or HVAC
Updating electrical to meet current code
Adding low-voltage systems (data, security, etc.)
Bringing old wiring up to modern standards

If your renovation touches the walls or ceiling, it’s time to call an electrician.

Common Questions About Commercial Interior Renovation

Q. Do I need a permit for interior electrical work?

ANSWER: Yes. In most cases, commercial renovations require permits and inspections, especially when circuits are added, modified, or panels are touched. We handle all permitting and inspection coordination for you.

Q. Can you phase the work so we can stay open during renovations?

ANSWER: Yes. We frequently phase electrical work so your business or tenants can remain operational during renovations. Whether that means working in specific zones, coordinating with your schedule, or sequencing tasks around active areas, we’ll develop a step-by-step plan that minimizes disruption and keeps the project moving forward.

Q. How do you coordinate with other trades during a renovation?

ANSWER: We work seamlessly with GCs, carpenters, HVAC, and other trades to keep the schedule moving and avoid rework. Good communication is one of our core values.

Q. What about code compliance?

ANSWER: Renovations are a chance to correct old code issues and bring systems up to modern safety standards. We’ll advise you if any wiring, grounding, panel work, or clearances need updating, and we’ll fix it right the first time.
