Modernizing outdated electrical equipment in a 16-unit apartment building

This Gough Street project involved a full service modernization for an older San Francisco apartment building with 16 units. The property had outdated Zinsco panels and a house panel that needed to be replaced with modern service and distribution equipment.

Max Electric retained the existing underground electrical service where it made sense, then relocated the electrical equipment to a new code-compliant location. The project included electrical panel replacement and service equipment upgrades, distribution panels, and construction of a dedicated electrical room.

The goal was not only to replace old equipment, but to create an organized system that could serve all 16 units safely, fit within the building’s physical limitations, and remain practical for future service and maintenance.

Project Scale

What the building needed from the electrical upgrade

The project required new distribution equipment, a dedicated electrical room, careful conduit routing, and a layout that could serve 16 apartment units from a limited service area.

16 Apartment units

The electrical modernization was planned around service and distribution needs for all 16 units.

$68K Project value

The scope included panel replacement, new service equipment, distribution pathways, and electrical room work.

UG Underground service retained

The Challenge

Fitting 16-unit distribution pathways into a tight San Francisco building

One of the biggest challenges was space. The garage entry area provided very limited room for service conduits and distribution pathways, yet the new system still had to serve all 16 apartment units and the house panel in a clean, code-compliant way.

The project required careful layout planning before installation. Every conduit route, equipment location, and bend had to be planned around the existing building conditions so the final electrical room would remain organized, accessible, and serviceable.

01

Available space reviewed

The team planned the electrical room layout around the narrow garage entry, existing structure, and underground service conditions.

02

Conduit pathways organized

Distribution routes were designed to serve 16 units while keeping the installation clean and readable.

03

Equipment relocated properly

The electrical equipment was moved to a new code-compliant location without abandoning the existing underground service.

Electrical Room

A dedicated electrical room designed for clean service access

The new electrical room became the core of the modernization. It allowed the service equipment, distribution panels, meters, and conduit pathways to be organized in one dedicated area rather than being squeezed into an outdated or non-compliant layout.

Because the building had limited space, the layout had to be compact without becoming messy or difficult to service. Max Electric planned the conduit runs, bends, and equipment placement to maximize the available area while maintaining a professional installation.

Organized service equipment New panels and meters were grouped into a dedicated electrical room for better long-term access.
Clean conduit routing Conduit pathways were routed carefully to keep the installation readable and serviceable.
Code-compliant relocation Electrical equipment was moved into a better location while preserving the existing underground service.

What the new electrical room supports

The completed layout gave the apartment building a cleaner electrical foundation for unit service, house loads, maintenance, inspections, and future electrical work.

Our Process

How the modernization was handled

The project required careful planning around existing underground service, equipment relocation, limited space, and distribution needs for a 16-unit apartment building.

Existing service reviewed

We evaluated the existing underground service, old Zinsco equipment, and available building space before finalizing the layout.

New layout planned

The service equipment was relocated to a code-compliant area with a dedicated electrical room and organized pathways.

Equipment installed

New service equipment, distribution panels, meter bank, house panel, and conduit routes were installed for the 16-unit building.

Final organization completed

The finished installation was arranged for cleaner access, professional appearance, and long-term maintainability.

The result: a cleaner electrical system for a 16-unit apartment building

Max Electric completed the Zinsco panel replacement and service modernization for the Gough Street apartment building, replacing outdated panels and building a new electrical room that could support the property’s current service needs.

The finished installation retained the existing underground service, relocated equipment to a code-compliant location, improved the organization of service conduits, and created a more professional electrical layout for all 16 units and the house panel.

Outdated Zinsco panels replaced

The old equipment was replaced with modern service and distribution equipment.

Underground service retained

The existing underground service was preserved while the electrical equipment layout was improved.

Clean electrical room completed

The new electrical room improved service access, organization, and long-term maintainability.
