Multi-Family and Mixed-Use Electrical in the Denver Metro
Unit wiring, house power, and ground-floor commercial space in one building, on one schedule.
Multi-family work is production wiring. The same unit repeats floor after floor, so the first stack sets the pattern for panel location, homerun routing, and box heights, and any mistake in it repeats too. Dwelling units bring their own rules for arc-fault protection, tamper-resistant devices, receptacle spacing, and kitchen and bath circuits. Inspections happen unit by unit instead of in one pass, which shapes how crews are staged across the building.
Mixed-use adds a second building on top of the first. Metering gets sorted early: individual unit meters, a house meter for corridors, garage, elevator, and site lighting, plus separate service for ground-floor commercial tenants whose build-outs may not be designed yet. Common-area scope looks commercial rather than residential, including egress and exit lighting, garage lighting on controls, EV conduit under the parking slab, and feeders sized for retail spaces still sitting as shells.
How is electricity metered in a mixed-use building?
Typically each dwelling unit has its own meter, a house meter covers corridors, garage, elevator, and site lighting, and ground-floor commercial tenants are metered separately. Meter stack location, utility clearances, and the service entrance path have to be locked in during design, not after framing.
What is different about wiring apartments versus a commercial tenant space?
Repetition and dwelling-unit code. Apartments follow residential rules for receptacle spacing, arc-fault and tamper-resistant protection, and unit panels, and they are inspected one unit at a time. A commercial space is a single open area with a load schedule driven by whatever the tenant is installing.
When should EV conduit go into a multifamily garage?
Before the slab is poured. Sleeves, stub-ups, and spare conduit to future stall locations cost very little while the ground is open, and panel space plus feeder capacity can be reserved at the same time. Adding it later means cutting finished concrete in an occupied garage.
