Electrician in Pomona

Infinity Electrical Inc. (CSLB #1100231) is a licensed electrical contractor working on houses, mobile homes, apartments and businesses in Pomona, from panel upgrades and EV charger circuits to rewiring and repairs. Pomona is a little different from most Edison cities: the city runs its own power supply program, Pomona Choice Energy, while SCE keeps the wires and the meter, and the city's Building and Safety Division schedules its regular inspections Monday through Thursday.

Working in Pomona

Infinity Electrical works on panel and service upgrades, car charger circuits, troubleshooting, rewiring, lighting and mobilehome electrical work across the City of Pomona. Most of the city's houses went up in or before the 1960s, so the usual Pomona question is whether an older service and panel can take on an EV, a heat pump or an ADU, and the answer is worked out with a load calculation before anything is bought.

Pomona incorporated on January 6, 1888, and took the name of the Roman goddess of fruit, chosen in an 1875 naming contest. By the 1920s it was known as the Queen of the Citrus Belt. The orchards are long gone, but the city they built is still visible in its historic districts, its downtown and the blocks of postwar houses that filled in around them.

Pomona had an estimated 147,807 residents in July 2025, by the Census Bureau's count, on about 23 square miles of land. Its biggest employers, according to a 2018 report cited by Wikipedia, include Pomona Valley Hospital Medical Center, the Pomona Unified School District, Cal Poly Pomona and Fairplex, home of the Los Angeles County Fair. About 64% of residents age 5 and up speak a language other than English at home, and our office offers customer assistance in English and Spanish.

What's common in Pomona homes

Pomona's 2021-2029 housing element, using 2019 Census survey figures, counted 40,846 housing units: 25,692 single-family detached houses (62.9%), 2,612 attached homes (6.4%), 10,832 units in multi-unit buildings (26.5%) and 1,622 mobile homes (4%). The same appendix says 85.9% of the city's homes were more than 30 years old in 2019, and the Census Bureau now puts the owner-occupied rate at 54.0% for 2020-2024, with an average of 3.37 people per household.

  • The 1950s city. One in four Pomona homes, 25.1% in the housing element's chart, was built in the 1950s, and another 14.9% in the 1960s. Houses of that era were wired for far fewer appliances than today's households run, and some still carry their original service. A panel upgrade is often the step that makes room for central air, an induction range or a charger, and the guide to heat pumps, induction and the panel explains how that capacity is worked out.
  • Lincoln Park and Wilton Heights. Pomona has five historic districts on the city's preservation page, among them Lincoln Park, Wilton Heights and Hacienda Park. Lincoln Park, designated locally in 1998 and listed on the National Register in 2004, lies between Garey and Towne avenues; the city counts 802 properties in the local district, and the National Register listing covers about 230 acres, mostly houses from the 1890s through the 1940s in Victorian, Craftsman and Revival styles. Wilton Heights, designated in 1999, has 534 properties dating from the late 1800s to the 1950s. Houses this old can still have knob-and-tube runs, ungrounded receptacles or a fuse panel; see rewiring.
  • Exterior changes in a district. Pomona uses Certificates of Appropriateness for alterations in its historic districts; a 2004 city notice, for example, covered one for modifying a porch and a garage. Moving a meter, a service mast or a panel to a street-facing wall on a district house is worth asking the Planning Division about first, before the electrical permit is drawn up.
  • Phillips Ranch. Pomona's newest neighbourhood grew from the 1980s on the hills between downtown and Diamond Bar and is almost entirely residential. The housing element puts 15.2% of the city's homes in the 1980s and only about 14% after 1989, so a Phillips Ranch house is usually younger than the rest of Pomona's stock, and EV chargers, garage subpanels and lighting updates are likelier questions there than knob-and-tube.
  • Mobile homes. The housing element counts 1,622 mobile homes in Pomona, about 4% of all units, and says mobile homes make up about 6% of owner-occupied housing in the city. California's Department of Housing and Community Development inspects mobilehome parks wherever the local government has not taken over enforcement, so the inspecting agency is confirmed before work on a park space begins; see mobilehome electrical.
  • Rentals and apartments. Renters occupied about 47% of Pomona's occupied homes in 2019, and more than half of renter households lived in multi-unit buildings, the housing element reports. In those buildings the work usually starts at the meter bank or the house panel, whether the owner wants chargers in the carport or a unit keeps tripping.
  • Hospital, campus and fairground. Cal Poly Pomona's campus lies partly inside the city limits, southwest of the junction of the 10 and the 57, and Fairplex hosts the county fair. The shops, restaurants and offices that serve students, patients and fairgoers bring their own lighting, signage and tenant-improvement work.

Permits and power in Pomona

The City of Pomona (ZIP codes 91766, 91767 and 91768) sits at the eastern edge of Los Angeles County. San Dimas lies to the northwest, La Verne and Claremont to the north, Diamond Bar and Chino Hills to the south, Walnut, South San Jose Hills and the City of Industry to the southwest, and Montclair and Chino to the east; Chino Hills, Montclair and Chino are across the line in San Bernardino County. The 10 and the 57 freeways meet near the city's west side, by Cal Poly Pomona.

Permits come from City Hall, four days a week. Building permits, plan review and inspections in Pomona come from the Building and Safety Division of the city's Development Services Department, which also includes the Planning and Code Compliance divisions. The division's inspection request page schedules inspections Monday through Thursday only, because City Hall is closed on Fridays, and notes that a requested slot depends on how many inspections are already booked. A request for a Monday inspection therefore has to be in by Thursday. On a main panel replacement, Edison generally reconnects the meter only after the city's inspection release, so a Pomona panel job is planned around that short week from the start.

Pomona buys its own power. Unlike Claremont, which is a member of the regional Clean Power Alliance, Pomona runs its own community choice program, Pomona Choice Energy, which the city describes as locally managed and not for profit. The CPUC's 2021 status report lists it as active in Edison territory since October 1, 2020, and SCE's current joint comparison table for the two suppliers shows two products, Pomona Choice and Pomona Choice 100% Renewable. According to SCE's community choice page, Edison still delivers the electricity and handles meter reading, billing, maintenance and outage response for every CCA customer. So the name on the generation line of the bill has no bearing on the wiring; meter work for a panel upgrade is still arranged with SCE.

Edison's side of the job. SCE lists panel upgrades and meter spots on an existing service on its building, renovation and planning projects page, and it takes calls for equipment relocations and overhead-to-underground conversions by phone. A new circuit, a fixture or a charger that fits on the panel a house already has stays on the customer side of the meter, so most smaller Pomona jobs involve only the city inspection.

Less hillside fire zone than the neighbours. The State Fire Marshal's 2025 local responsibility area maps put about 2,157 acres of Pomona in moderate, high or very high fire hazard severity zones, and only 24 acres of that in the very high class. Diamond Bar, next door, has 3,433 acres of very high zone and Claremont 3,188, according to the same tables, so the hills around Pomona carry more of that designation than the city does.

The permits and utilities guide explains the whole picture for the three counties we serve.

Around Pomona

Each city around Pomona sets its own permit process, and the power supplier changes at the line as well. Claremont, to the north, is a Clean Power Alliance member, so Edison delivers there but CPA supplies the energy, not Pomona Choice Energy. La Verne, San Dimas, Diamond Bar and Walnut are not on CPA's member list, and none of them is part of Pomona's program, so a house there normally buys its power straight from Edison. South San Jose Hills and the Walnut Islands, to the southwest and west, are unincorporated county land, where building services come from Los Angeles County Public Works. Montclair and Chino, on Pomona's east side, and Chino Hills, to the south, are in San Bernardino County, which is outside the Los Angeles, Orange and Ventura counties that Infinity Electrical serves; they are named here only to mark where the county line runs.

Questions people ask

Who issues electrical permits in Pomona?

The City of Pomona does, through the Building and Safety Division of its Development Services Department. That division checks plans, issues permits and performs inspections, which run Monday through Thursday because City Hall is closed on Fridays. Los Angeles County Public Works issues permits for unincorporated neighbours such as South San Jose Hills, not for addresses inside Pomona.

Why does my Pomona electric bill show Pomona Choice Energy?

Because Pomona runs its own community choice program, which has supplied generation for enrolled customers since October 1, 2020. Southern California Edison still delivers the power, reads the meter, sends the bill and restores outages, so a panel upgrade or meter change is still coordinated with SCE, not with the city's energy program.

Is Pomona part of Clean Power Alliance like Claremont?

No. Pomona is not on CPA's member list; it has its own program, Pomona Choice Energy, which offers a standard product and a 100% renewable option according to SCE's joint comparison table. Claremont, next door, is a CPA member, so two neighbouring houses on either side of the city line can have different suppliers on the same Edison lines.

My house is in the Lincoln Park Historic District. Does that change electrical work?

Inside the walls, usually not; the work is permitted and inspected by Building and Safety like any other house. Outside is different: Pomona has required a Certificate of Appropriateness for exterior work as small as a porch and garage change, so a new meter location or a service mast on a visible wall is raised with the Planning Division first. Many Lincoln Park homes date from the 1890s to the 1940s; see rewiring and reading the electrical notes in a home inspection.

Can a 1950s Pomona house take an EV charger without a new panel?

Sometimes, and a load calculation is how to find out. About a quarter of Pomona's homes date from the 1950s, and some still have a small original service; others have been upgraded since and have room. A load-managed charger can help where capacity is tight; see EV charger installation.

I own a mobile home in Pomona. Who inspects electrical work on my space?

Often the state: California's Department of Housing and Community Development inspects mobilehome parks wherever the local government has not taken over enforcement, so the inspecting agency is confirmed before work begins. Ask park management too whether the job touches park-owned equipment such as the pedestal. Pomona has 1,622 mobile homes by the housing element's count; see mobilehome electrical.

Can I get a Monday inspection in Pomona?

Yes, but the request has to go in by the Thursday before, since City Hall is closed on Fridays and inspections run Monday through Thursday. The city also notes that a requested slot depends on how many inspections are already booked, so a panel job is scheduled with that in mind.
