What commercial electrical work involves in Riverside

Three RPU commercial classes

Riverside Public Utilities (RPU) is the city’s own electric utility, so SCE business rate plans do not apply here. RPU sorts commercial customers by demand.

• Schedule A, flat rate. For commercial accounts at or under 20 kW in any two of the previous 12 months.
• Schedule A, demand basis. For 20 kW up to 150 kW.
• Schedule TOU. For new service designed for 150 kW or more, or existing customers at or above 150 kW in any two of the previous 12 months.

New commercial customers are placed by the demand level the utility determines, and a customer who exceeds or falls below a class is transferred. For a small business, the line to watch is 20 kW. A restaurant adding a walk-in cooler and a second oven, or a shop adding chargers, can cross it. The bill then adds a demand charge, and the electrician’s load calculation should show the number before the order goes in. The panel and service upgrades page explains how to read that calculation.

A discount for growth, with a high bar

RPU has an Economic Development and Expansion rate for businesses relocating or expanding in Riverside. A new RPU customer needs at least 500 kW of minimum demand. An existing customer needs new load of at least 150 kW of monthly demand or 20 percent of existing load, whichever is higher. The rate also names research, development and technology companies and green technology or manufacturing firms, defined by industry codes. The discount is 40 percent per month in the first year and 20 percent in the second, on a 4-year contract. Most small shops will not qualify, but a manufacturer or lab planning a new line should call RPU’s account managers at 951-826-5485 before ordering equipment.

Rebates for lighting and chargers

RPU’s business lighting incentive pays by energy saved over one year. Level 1, standard efficient fixtures, pays $0.06 per kWh. Level 2 adds daylighting or occupancy sensors and pays $0.08. Level 3 covers projects with HID replacement or a combination of fixtures, controls and daylight harvesting, and pays $0.10. Caps are $25,000 for flat rate customers, $50,000 for demand customers and $100,000 for time-of-use customers, and a rebate cannot exceed 50 percent of project cost. Lighting has to be approved by RPU and installed at the service address. See LED lighting retrofits for how the energy code treats a fixture change.

For chargers, RPU’s business program reimburses equipment up to $5,000 per public-access station, and up to $10,000 per station for schools, qualified affordable housing, or DC fast sites with two or more ports, with a limit of five stations per location. A separate infrastructure rebate covers up to 50 percent of grid-side upgrade costs, up to $50,000, and RPU designs that work. The chargers must be new Level 2 or faster, open to the public in business hours, and installed by a licensed contractor with a city electrical permit. Applications are due within 180 days of installation, and the offer is first come, first served until funding is spent. The commercial EV charging page covers the design side. The city utility rebates guide covers household programs.

City permit lines for commercial work

The city’s fiscal year 2026/27 fee schedule, effective July 1, 2026, has commercial lines that differ from the home lines. A commercial EV charger is $164 each, against $66 for a residential one. Commercial lighting standards are $45 each, wall-mounted illuminated signs $94 each and monument signs $205 each. A 14 percent surcharge applies to items marked in the schedule. In the fire section, a tenant improvement fire sprinkler system with 1 to 199 sprinklers is $389 and a tenant improvement hood system plan check is $264. The city’s permits page says some permits are issued same day over the counter, but its examples are residential, and other projects may need plan review. Other agencies such as Planning, Public Works or Fire may have to approve first. Call the permit counter at 951-826-5800 for the path your job takes. The tenant improvement electrical page lists typical scope.

Historic downtown

For designated or eligible historic properties, such as buildings in the Mission Inn area downtown, the city says all exterior alterations, additions and repairs need a Certificate of Appropriateness, even when no building permit is required. The Cultural Heritage Board or historic preservation staff reviews the application. A new blade sign, an exterior conduit run or a moved meter on a downtown storefront can fall under that. Interior wiring is not the issue. Ask the Planning Division before the sign or exterior work is ordered.

What to send

Commercial electrical work in Riverside is available through the partner electrician. Send the building type, the address, whether you are the tenant, the owner or the property manager, and what is wrong or planned. A photo of the main panel and the RPU meter helps. Start from the commercial hub, the Riverside residential page or the county overview.
