The PG&E Step That Holds Up More ADUs Than Framing Does

An ADU budget usually covers the parts a homeowner can picture. Framing, windows, drywall, tile, and the inspections along the way.

What almost nobody plans for is the stretch of calendar that belongs to the electric utility. I have seen projects in Salinas, Seaside, and out toward Prunedale sit at 95 percent complete waiting on a meter set. The crew is finished, the site is clean, and the power is still off.

So this is the utility side of an ADU in plain language. What the electric service application actually is, when to file it, how the meter decision moves both cost and timeline, and what the state changed in 2024.

Every ADU Has Two Clocks, and You Only Control One

The first clock is the build. That one runs on my schedule, the subcontractors, material lead times, and the local inspector. When it slips, it is usually something I can explain and something I can push on.

The second clock is the utility. A new or upgraded electric service is its own application with its own queue, and it moves at the pace of utility engineering and crew availability. No contractor sets those dates.

One homeowner said it better than I can in a review after a garage conversion in Salinas: “The project took a little longer than expected, but this was due to PG&E’s scheduling and availability.” (Blanca B.)

That project was not slow because of the crew. It was finished and waiting. And this is the single most common reason a Monterey County ADU misses its original completion date.

So when you compare bids and someone hands you a tidy month count with no mention of the utility, ask where that step sits in their schedule. A contractor who has built here knows the answer.

What the PG&E Side of an ADU Actually Looks Like

This is the part no local contractor content explains, so here it is start to finish. The service application is separate from your city or county building permit, and filing one does not start the other.

The general path looks like this:

• You submit a service application describing the new or upgraded service
• Utility engineering reviews the site and designs the connection
• You receive a cost letter or contract to sign and pay
• Customer-side work gets built, meaning trenching, conduit, panel, and meter socket
• The local building inspector signs off on the electrical work
• The utility schedules an energization visit to set the meter and turn it on

The practical trigger point is usually plan approval plus an address assignment for the new unit. That is when you have the numbers the utility needs.

Submitting then, instead of waiting until framing is up, is the biggest schedule lever a homeowner has on an ADU. It costs nothing and it can save weeks or months.

The path also depends on what you are building. A detached backyard unit, a garage conversion in Seaside or Marina, and an attached addition in south Salinas can each follow a different service route.

The Meter Question: Separate Service, Submeter, or Shared

This question drives both cost and timeline, so it belongs in the first conversation, not month four.

California law limits what a local agency can require of an ADU when it comes to separate utility connections. But the utility still sets its own technical service requirements, and those are a different rulebook. Homeowners should confirm both with their jurisdiction and with the utility rather than assuming one answer covers the other.

In practice there are three real options:

• A separate metered service for the ADU, with its own account and its own bill
• A submeter behind the existing meter, where the main account pays and usage gets tracked privately
• Shared service with the main house, where the ADU simply draws off the existing panel

How you plan to use the unit usually decides it. A homeowner building for aging parents on a half acre in Salinas often does not care about billing separation at all.

Someone renting a 450 square foot studio in Watsonville cares a lot. Clean separation keeps the tenant relationship simple and keeps you out of the business of splitting a bill every month.

Comparing the Three Meter Paths

Here is how the three options tend to play out on real Monterey County and Santa Cruz County projects. Specifics vary by site, so treat this as orientation rather than a rule.

The Utility Track, Step by Step

This is the sequence the utility side follows on a typical ADU, and where the waiting usually happens.

Older Salinas Homes and the Load Problem Nobody Priced In

A lot of housing stock in Salinas, Gonzales, and Prunedale was built decades ago on modest main service. That was plenty for the original house.

Then you add a full second dwelling with heat pump space conditioning, a heat pump water heater, and induction cooking, and the whole property can land past what the existing panel and service drop can carry.

That turns into a load calculation, which is the math that tells you whether your service holds. Sometimes it points to a service upgrade. Sometimes it points to utility-side work like a new transformer or a longer trench, and that is where the timeline really stretches.

Cost is site specific, and I will not pretend otherwise. The factors that move the number most are:

• Distance from the nearest transformer
• Overhead versus underground service
• Trench length and what the trench has to cross, like driveway or hardscape
• Engineering and design fees on the utility side
• Whether a second service is involved instead of a shared one

Only a site-specific review gives a real figure. If you are still building a rough budget, our breakdown of what an ADU actually costs in Monterey County gives you the wider picture, but the utility line item is the one that varies most from lot to lot.

What Changed in 2024: The State Put Targets on the Utility

This part is genuinely useful and almost nobody in this market talks about it.

Under the state legislation known as the Powering Up Californians Act, the California Public Utilities Commission adopted a decision in September 2024 that set average and maximum target timelines for the energization steps the large electric utilities control. It also added reporting requirements and a process for customers to report energization delays. The CPUC published a plain summary in its energization fact sheet.

Let me be honest about what that does and does not mean. Targets are not guarantees. Utility workload, crew availability, and any upstream capacity upgrades still drive the real-world date on your lot.

What it does mean is that the process now has published expectations and a complaint path. That is worth knowing before a project stalls, not after.

Running the Tracks in Parallel Is the Whole Job

One Salinas homeowner planning a 1,200 square foot unit told us they needed someone “handling all the pre construction permits and everything else associated with it.” That is really a request for someone to run several tracks at the same time.

On a typical ADU here, the parallel tracks look like this:

• Local plan review with the city or county building and planning departments
• Utility service application filed as soon as plans and address are set
• Environmental health and water review on rural parcels, which matters on lots near San Juan Bautista or Hollister

When those run one after another, you add months for no good reason. When they run side by side, the utility queue overlaps with construction instead of sitting on the end of it.

Requirements vary by jurisdiction and by utility, and the specifics change. Verify current requirements with your local agency before anyone counts on a date. If you are in San Benito County, the rules differ from Salinas in ways that affect this sequencing directly, and permit clocks themselves have shifted under recent state law.

The reason I lean on coordination rather than craftsmanship claims is simple. At Aldridge Construction we run the agency sequencing and the utility paperwork on the same schedule as the build, and homeowners hear about issues as they come up rather than after the fact. On ADU work, where one step sits outside anyone’s direct control, honest updates are the only thing that keeps expectations real.
