Vallejo is Solano County's largest city, with historic homes near Old Town and newer neighborhoods farther out. HAXX handles HVAC, electrical and appliance work under one license.
The Heritage District holds Victorians built mostly from 1860 to 1890, and St. Vincent's Hill grew as housing for Mare Island shipbuilders. Exterior changes there may need a Certificate of Appropriateness.
Older homes often have small services and wiring added over decades. Vallejo requires permits for electrical service, sub-panels and most electrical installations.
MCE supplies electricity in Vallejo and lists its own heat pump rebates; confirm eligibility with MCE. Air District rules limit new gas water heater sales from 2027.

For most homes. Vallejo's mild winters suit heat pumps, and the same system cools during heat waves. Older homes without ducts often use mini-splits.
MCE has served Vallejo electricity customers since 2021. MCE lists heat pump rebates with its own eligibility and contractor rules, so confirm directly with MCE.
A load calculation answers that. Many homes have room; others need load management or a service upgrade, which requires a Vallejo permit.
Permits are applied for online through eTRAKiT or at the Central Permit Center at City Hall, 555 Santa Clara Street. HVAC, water heaters and electrical service work all need one.
