Antioch solar: one utility, real heat, a $316 permit

East Contra Costa's no-CCA island

The map is genuinely odd. MCE's member list for Contra Costa County includes Concord, Danville, El Cerrito, Hercules, Lafayette, Martinez, Moraga, Oakley, Pinole, Pittsburg, Pleasant Hill, Richmond, San Pablo, San Ramon, Walnut Creek and the unincorporated county. Antioch is absent. The CalCCA statewide service-area document does not list Antioch under any CCA either, and PG&E's own CCA page confirms the pattern. Antioch households buy both generation and delivery from PG&E.

Why should a solar shopper care? Because MCE attaches real money to exports for its customers: a Solar Bonus Credit, an Energy Export Bonus Credit, CARE and FERA solar credits, storage credits. Those programs are available a few miles away and unavailable at an Antioch address. Any proposal that quietly imports CCA credit assumptions from a neighboring city is wrong on arrival. In practice we see this exact error in template-driven quotes more often than you would expect.

The flip side is simplicity. One company, one bill, one set of tariffs. For a homeowner comparing quotes, that removes an entire category of confusion that Richmond and Pittsburg customers have to untangle.

$316 to the City, and a lane you have to stay inside

Antioch's adopted fee schedule lists the residential solar photovoltaic permit at a flat $316.00, effective July 1, 2025. That sits comfortably under the $450 statutory cap that Government Code 66015 sets for systems up to 15 kW. Note the stacking, though: the SolarAPP+ platform adds its own $35 processing fee, plus $25 more when a battery is included. A quote that says the permit costs $316 and stops there is understating the government cost. The Master Fee Schedule and the City's Solar Permits page hold the line items.

The workflow runs through two systems, and the distinction matters. SolarAPP+ performs the plan review and issues the approval documents. The City's Citizen Access portal takes the payment and issues the actual permit. Once documents are uploaded and fees are paid, the Instant Solar permit issues automatically and the job card prints from the portal. That is the fast lane the state pushed cities toward under Government Code 65850.52, which reaches residential systems up to 38.4 kW AC. The CEC's tracking workbook records Antioch as a SolarAPP+ Platform jurisdiction with an $80,000 CalAPP award from May 2023, and Antioch appears in NREL's availability table.

Three lane rules that catch people. First, the instant path is for registered contractors only; owner-builders go through the standard Building Division submittal. Second, projects outside the City's eligibility checklists fall out of the automated lane entirely. Third, and this one causes avoidable repeat visits: if the printed SolarAPP+ Inspection Checklist, single-line diagram and permit card are not physically on site at inspection, the inspection automatically fails. Inspections book in Citizen Access with AM and PM windows, 9 to noon and noon to 3.

One more sequencing trap from the City's own FAQ: a re-roof on a house with existing panels needs two permits, a re-roof permit plus a solar removal and reinstallation permit. Roofers and solar crews who have not coordinated before the tear-off are how that job becomes a saga.

Exports here follow the state tariff, with nothing added

New Antioch interconnections fall under the Net Billing Tariff, adopted in CPUC Decision D.22-12-056 and applied to applications submitted on or after April 15, 2023. Export compensation under that framework is not the retail rate. The CPUC's program page carries the statewide rules, and our California page covers them at length, so we will not repeat the mechanics here.

What is specifically true in Antioch: there is no CCA layer to sweeten exports. No Solar Bonus Credit, no Energy Export Bonus Credit, no CCA storage credit. The design consequence is direct. Oversizing a system to farm export credits is a weaker strategy here than almost anywhere in Contra Costa County. Size to the household's consumption, weight the evening peak, and let exports be a byproduct rather than the plan. For context, PG&E's average residential price across 2024 was 39.617872 cents per kWh in EIA's bundled sales data, which is the scale of what self-consumed solar avoids.

Who actually bids Antioch jobs

Much of the installer base serving Antioch operates out of Brentwood next door. That is normal for East County and not a red flag. What you should verify per bidder: an active CSLB license, whether the design fits Antioch's SolarAPP+ eligibility checklist, and who eats the cost if a battery or layout change pushes the job into standard plan review.

One sorting question that separates crews quickly: ask how they handle the printed-document requirement at inspection. An installer who knows Antioch answers in one sentence. An installer who has never worked here asks what you mean.
