Do I need a permit to replace a worn-out breaker in Vallejo?

Not if the new breaker is of the required capacity and goes in the same location; the city's residential exemptions list that swap. A new or upgraded service panel, or a subpanel, is a different matter. The Building Division lists both among projects that need a permit and an inspection.

We live on Mare Island. Is PG&E our electric utility?

No. Pittsburg Power Company, a California joint powers authority, operates the island's electric and gas distribution system under the name Island Energy. PG&E's part is the 115 kV line that brings the power to the island. For a service upgrade or a new meter on Mare Island, Island Energy is the utility your contractor coordinates with.

Does rewiring a Heritage District Victorian need the landmarks commission's approval?

Not for the wiring inside, unless the house is a designated landmark. The municipal code exempts interior alterations in historic districts otherwise. Exterior changes visible from the street are another matter: they go to the Architectural Heritage and Landmarks Commission after a 14-day notice. The city's interactive zoning map shows whether a property carries a designation.

Permits and local rules

The permits and reviews behind Vallejo electrical work

What needs a permit, and what does not
The city says most electrical installations, repairs and replacements require permits, naming electrical service and subpanels, HVAC systems and wall heaters among typical projects. The residential code's exemptions cover listed cord-and-plug temporary decorative lighting, reinstalling receptacles but not the outlets for them, replacing branch-circuit overcurrent devices of the required capacity in the same location, and equipment running under 25 volts and 50 watts. Homeowners doing their own work can apply as owner-builders after filling in the city's form.

Section 16.614.09: certificate of appropriateness
Before construction, alteration or an addition to any structure in a historic district or on a landmark property, Vallejo requires a certificate of appropriateness. Ordinary maintenance and upgrading that does not significantly change the designated structure is exempt, and so are interior alterations unless the building is a landmark. Exterior alterations visible from the street are reviewed by the Architectural Heritage and Landmarks Commission after a 14-day notice, measured against the Secretary of the Interior's standards for historic properties.

Instant permits and the eTRAKiT portal
Contractors and homeowners applying for residential solar or energy storage permits under SB 379 can get instantaneous issuance through Symbium, the Building Division says. Other permits run through eTRAKiT, the city's online permitting system, which new users register for before applying. Inspections are requested there or by phone, assigned a four-hour morning or afternoon window, and the permit card has to be printed and on site when the inspector arrives.

Who supplies the power and who delivers it
MCE replaces only the generation of electricity; PG&E continues to provide gas service, electricity delivery, billing and power line maintenance, and every MCE customer remains a PG&E customer. MCE counts 88 percent of Vallejo's electricity accounts on its service. Mare Island sits outside that arrangement: Pittsburg Power Company operates the island's electric and gas distribution as Island Energy, with power arriving over a 115 kV PG&E line from the Western Area Power Administration.

State license for this work: C-10 Electrical. Look up a contractor's license on the CSLB website (cslb.ca.gov).

The work

From fuse-era circuits to rooftop batteries

New service panels and subpanels
Vallejo's Building Division puts electrical services and subpanels on its list of projects that need a permit, while swapping a branch-circuit breaker of the required capacity in the same spot is exempt. A panel change also involves the utility, since MCE only buys the electricity: PG&E still handles delivery, meter reading and power line maintenance for MCE customers. On Mare Island that conversation is with Island Energy instead. Applications filed after January 1, 2026 are checked against the 2025 California codes.
Rooftop solar and battery storage
Under SB 379, Vallejo issues residential rooftop solar and battery storage permits instantly through a Symbium portal, beginning with a check that the address lies inside city limits. Systems that do not fit that path go through regular plan review, for which the city keeps a separate photovoltaic and solar checklist. Either way, the wiring, inverter and battery connection are work for a contractor holding the C-10 Electrical class, and the system still has to pass the city's inspection.
Rewiring inside a historic house
Interior work in St. Vincent's Hill or the Architectural Heritage District needs no certificate of appropriateness unless the house itself is a designated landmark, so replacing old circuits behind plaster is a building-permit matter. What shows outside is another question. The code sends exterior alterations visible from the street to the Architectural Heritage and Landmarks Commission with a 14-day notice, so a relocated meter, a new service mast or conduit run up a front wall is worth raising with the Planning Division before the work is drawn.
A circuit for an EV charger
State law under AB 1236 requires every California city to offer an expedited, checklist-based permit process for EV charging stations. In its 2022 response to the Solano County Civil Grand Jury, Vallejo said chargers faced no discretionary review and were handled as ordinary building permit requests, while an ordinance and checklist were being drafted. A home charger still needs an electrical permit, and a load calculation shows whether the existing service can carry it or the panel has to grow first.
Grounding checked after blue-green stains
Vallejo treats its water to keep it from leaching copper, and the Water Department notes that copper corrosion inside a home can instead come from the electrical system being grounded to the plumbing. Blue-green staining at fixtures is the sign it describes. A plumber looks at the pipes, while a C-10 contractor can check the grounding and bonding of the service, and whether a stretch of plastic pipe from a later repair broke a path the system relied on.

The houses here

Wiring from Victorian blocks to a shipyard power plant

Old electrical work in Vallejo turns up in houses as different as the shingled 1868 Italianate farmhouse at 639 Virginia Street, Will Jones's brown-shingle homes of the late 1800s and early 1900s on Georgia Street, and Craftsman bungalows built in groups where shipyard workers lived. St. Vincent's Hill's period of significance runs from 1868 to 1947, so a single block can hold wiring from many decades. Mare Island had its own grid early: Building B-121, its 1918 central power plant, fed electricity out to the shop buildings, and the island's distribution still belongs to a separate utility. Newer subdivisions such as Northgate and Hiddenbrooke are another job entirely.

Part by part

Where Vallejo's electrical paperwork changes

Mare Island
Island Energy delivers gas and electricity to more than 600 customers here, about 380 of them residential, so service upgrades and meter questions go to it rather than PG&E. Work touching contributing buildings in the historic district also follows the Mare Island Specific Plan and its design guidelines.
St. Vincent's Hill
Roughly bounded by Mare Island Way and Butte Street, Marin Street, Quincy Alley and Florida and Carolina streets, with houses from 1868 to 1947. Rewiring inside is a building-permit job, but new equipment on a street-facing wall can bring the landmarks commission in.
Architectural Heritage District
Centered on Georgia Street between Sutter and Monterey streets, with Victorians going back to the 1850s. The same certificate rules apply, and inside a designated landmark even interior changes need one; the city counts 82 landmarks and maps them online.
East Vallejo, ZIP 94591
The Energy Commission's ZIP code list assigns 94591 to Title 24 climate zone 12, while the city's other three ZIP codes sit in zone 3. Energy code compliance for a heat pump or cooling upgrade is checked against the zone, so the address matters.

Before you hire

Questions to put to a Vallejo electrician

Is the house on PG&E service or, on Mare Island, Island Energy, and who will arrange the utility side of a panel change?
Will a load calculation show whether the present service can take an EV charger, heat pump or induction range?
In a historic district, will any meter, mast or conduit change be visible from the street, and has the Planning Division seen the plan?
For solar or batteries, does the system qualify for the city's Symbium instant permit or does it need regular plan check?
Is the C-10 Electrical license current on cslb.ca.gov, and will the permit be pulled in the contractor's name through eTRAKiT?

Still deciding?

How quickly can a Vallejo rooftop solar permit be issued?

For residential rooftop solar or battery storage that fits the state's SB 379 path, the city offers instantaneous permit issuance through Symbium, after checking that the address is inside city limits. The installation still has to be inspected, and the Building Division recommends requesting inspections at least three business days ahead because of its workload.

How do electrical inspections get scheduled in Vallejo?

First come, first served, through eTRAKiT or the city's phone line. Online requests must be in by 3 p.m. the day before, and the city suggests asking at least three business days ahead. You get a window of 8 a.m. to noon or noon to 4 p.m., and the printed permit card must be on site.
