Call (844) 430-7681Request an estimateWestminster began as a church settlement, not a suburb. The city's history page says the Reverend Lemuel P. Webber founded it as Orange County's second Presbyterian temperance colony and named it for the Westminster Assembly of 1643; Wikipedia puts the founding in 1870. Farming kept the town small for decades. After the Second World War many servicemen who had trained in Southern California stayed, and the population went from about 2,500 in 1942 to nearly 10,800 in 1956.
Incorporation came in 1957, when voters approved a new city joining Westminster and Barber City by 1,096 votes to 1,008; Midway City was part of the original plan but pulled out and is still unincorporated. Growth kept going after that: census counts show 33,663 residents in 1960 and 60,076 in 1970. A house built during that run was wired for a much smaller list of appliances than a household runs today.
Infinity Electrical Inc. (CSLB #1100231) works with Westminster homeowners, landlords, mobile home owners and shopkeepers. Each estimate starts with the existing service, the panel and the loads the customer is planning, and the city permit and Edison's part of the job are coordinated where the work needs them. Customer assistance is available in English and Spanish.
Areas we cover in Westminster
Good to know
4.9★ from 232 Google reviews across our service area · Licensed C-10 #1100231 · Free estimates on eligible work
Westminster is a dense city of about 91,000 people in close to 28,000 households, split almost evenly between owners and renters: Census Bureau estimates for 2019 to 2023 put the owner-occupied rate at 52.2 percent, with about 3.2 people per household.
Westminster (ZIP codes 92683 to 92685) issues its own building permits. The Community Development Department is responsible for building construction regulation, and its Building Division issues building permits and has plan check and inspection staff. Unincorporated Midway City sits mostly inside Westminster's boundaries, so a property can be surrounded by the city without being in it; the parcel, not the mailing address, decides which office issues the permit.
Westminster Build. The city runs permit work through an online portal it calls Westminster Build, described as a one-stop shop for development and permit applications. Applicants can check plan and permit status, pay invoices and see the day's inspection schedule, and the public can search existing permits, plans and inspections. The Building Division's application forms page also points to the fee schedule the City Council adopted for Community Development, in effect since September 1, 2025. For a job that needs a permit, the application, fees and inspection are coordinated as part of the work.
Chargers for businesses and apartments. Westminster publishes an eligibility checklist for expedited electric vehicle charging station permits at non-residential buildings. When a project meets every item, plan review starts the day after submittal and takes up to 3 business days; other charging projects take up to 10 business days. The checklist asks for a load calculation, a site plan signed off by the Planning Division, a separate electrical plan with a single-line diagram, and the existing panel's amperage, location and spare breaker space, and it requires the electrical plans to be stamped and signed by a California electrical engineer or a C-10 contractor. It also states that approval is not subject to a homeowners association.
Solar is on its own track. Under state law Westminster offers automated permitting for eligible rooftop solar on homes through SolarAPP+ and the city's permit software, as its solar permit page explains. Infinity Electrical does not install solar; on a house that already has panels on the roof, a panel change, charger or new circuit is planned around the existing system.
Edison's part. Southern California Edison serves Westminster and owns the lines and the meter. SCE takes panel upgrade and meter spot requests for an existing service through its Building, Renovation and Project Planning Portal, so a panel replacement or service upgrade has an Edison step as well as a city inspection, and the two are lined up in order. A new circuit or fixture that fits on the panel the house already has stays on the customer's side of the meter.
The permits and utilities guide explains the whole picture for the three counties we serve.
Westminster is boxed in by other jurisdictions. Garden Grove wraps around its north and east sides and shares Little Saigon with it; Huntington Beach and Fountain Valley lie to the south, and Seal Beach to the west. Each of those cities runs its own building department. Midway City, in the middle of Westminster, is unincorporated county land with no city government of its own, so its permits do not come from Westminster at all. Santa Ana is a short distance east, past a narrow strip of Garden Grove. Before writing an estimate near any of these lines, the jurisdiction is checked against the parcel.

No phone quotes and no guessing. A written estimate after we've seen the job, then permitted, inspected work.
Call or send the form. A photo of the panel or the problem helps us come prepared.
We come to your home or business and look at the panel, wiring or site.
Scope, price and timeline in writing before you decide anything.
We pull the permit, coordinate your utility when needed, and finish with the inspection.
The City of Westminster Building Division, part of the Community Development Department, issues electrical permits and inspects the work. Applications, status checks and invoice payments go through the city's Westminster Build portal, and the permit and inspection are coordinated as part of the job.
Only if the parcel is inside Westminster's city limits. Midway City is an unincorporated community surrounded mostly by Westminster, and building permits there come from OC Development Services, part of OC Public Works, so two houses on the same street can have different permit offices. The jurisdiction is confirmed from the parcel before the estimate.
Up to 3 business days of plan review, starting the day after submittal, if the project meets every item on the city's expedited checklist for non-residential charging stations; otherwise review can take up to 10 business days. The checklist needs a load calculation, a site plan signed off by the city's Planning Division and a single-line diagram, with the electrical plans stamped and signed by a California electrical engineer or a C-10 contractor, all of which go into planning a commercial EV charger installation here.
No, Westminster is not listed among the authority's member cities, so Southern California Edison supplies and delivers the power. Fountain Valley, next door, is a member with service starting in 2027. Either way, Edison owns the meter, so a panel upgrade involves an SCE request alongside the city permit.
Yes, Infinity Electrical takes on repairs, added circuits and panel work for mobile home owners, residents and park operators in Westminster. Because a park's electrical system is partly shared, the line between the home's equipment and the park's is confirmed first, along with the inspecting agency. Details are on the mobile home electrical page.
Yes, tenant improvements for restaurants, bakeries, salons and stores along Bolsa Avenue are part of the commercial work done in Westminster. The job starts with what the existing service can supply, since kitchen equipment and some HVAC units need dedicated or three-phase circuits; the commercial electrical page covers that kind of tenant work.
