We pull electrical permits in Manhattan Beach often enough that the counter at 1400 Highland Ave knows the crew. Most of the calls we get are not new construction. They are homeowners west of Sepulveda who want a Level 2 EV charger, a heat pump, or an induction range, and the 100A panel from 1978 is not going to carry it.
Salt air also matters here. The corrosion on meter sockets and service masts west of Sepulveda is real, and the inspector will flag a rusted weatherhead before they sign off a panel swap. This post walks through what to file, when to file it, and how to keep the Edison side from blowing up the schedule.
The permit you actually need
A like-for-like panel swap, a new branch circuit, a sub-panel, or an EV charger circuit all need a permit. The fee schedule the city publishes lists an electrical panel upgrade at "$220 + inspection," which is what we see on the receipts. Single device replacement (one outlet, one switch) does not need a permit. Anything beyond that does.
For Manhattan Beach, the Building and Safety division runs out of 1400 Highland Ave, Mon through Thu 7:30am to 5:30pm with alternate Fridays. Phone is (310) 802-5500. Over-the-counter is possible for straightforward panel work if your load calc and single-line are clean.
A remodel that touches electrical as part of a larger scope gets bundled into the building permit. The city's plan-check range for full submittals runs 6 to 10 weeks, and the electrical sheets ride that same clock.
Load calculation drives everything
The main breaker rating on the existing panel is not the same as available capacity. CEC Article 220 sets the load calc, and that calc is what the plan checker uses to approve or reject a panel.
We run the numbers before we promise anything. A 100A panel with an existing electric dryer, electric range, and central AC often has no room for a 40A EV circuit plus a future heat pump. The honest answer in that case is service upgrade to 200A, which is what CEC Article 230 expects for new construction and most additions.
400A services show up on the larger Hill Section custom homes, especially when there are two EV circuits, a pool, and all-electric kitchens. We size for the actual load, not the wish list.
Edison is the long pole
Here is the part that surprises homeowners. The city permit is the short timeline. The Edison side is the long one.
Edison panel-upgrade lead time runs 8 to 14 weeks from application to energization in our recent experience. Service drop coordination, transformer capacity checks, and underground feed routing all fall under Edison Rule 16. If your block is on overhead service and you want to go underground, add time.
We file the Edison Service Planning application the same week we submit to the city. That parallel track is the only way to keep a panel upgrade from holding up drywall or finish.
EV-ready and Title 24
New residential construction in Manhattan Beach has to comply with Title 24 Part 6 §150.0, which requires at least one EV-ready space per dwelling. That means a dedicated 240V circuit raceway and panel capacity, not just a future "we will deal with it" note on the plans.
For commercial work, §140.10 sets EV charging infrastructure thresholds based on parking count. We have run those numbers on a few mixed-use jobs in the South Bay, including coordination with the structural and finish trades on Raymond Estate where the service entrance had to be sized for the full electric load up front.
The mistake we see on remodels is treating the EV circuit as an afterthought. If the panel cannot carry it, you are looking at a service upgrade, an Edison application, and a second inspection cycle.
Older homes, knob-and-tube, and aluminum branch wiring
Sand Section and Tree Section have plenty of pre-1970 houses. When we open walls on these, we sometimes find knob-and-tube or aluminum branch-circuit wiring still energized.
Insurance carriers do not like either one. The inspector will flag it during a remodel, and the scope can grow from a kitchen circuit to a partial rewire fast. We tell clients up front: if the house is older than 1970 and we are opening more than one wall, budget time for discovery.
The fix is copper THHN/THWN-2 conductors on the branch circuits, properly terminated, with GFCI and AFCI protection per current CEC where required. That means kitchens, baths, garages, bedrooms, and outdoor receptacles.
Inspections and sequencing
A typical panel-upgrade job runs a rough inspection before the meter is set and a final after Edison energizes. For a remodel with new branch circuits, you also get a rough-in inspection at the framing stage before insulation.
Our typical timeline for electrical-only scopes runs 1 to 6 weeks from permit issuance to final, depending on whether Edison is involved. Panel swaps with no service upgrade are on the short end. Anything touching the service drop pushes to the long end or beyond, governed by Edison's schedule.
We coordinate the city inspection request the day Edison confirms the cut-in date. Doing it the other way around adds a week every time.
FAQ
Do I need a permit to install a Level 2 EV charger? Yes. A new 240V circuit is a permitted scope. If your existing panel has capacity, it is a straightforward filing. If not, you are looking at a panel or service upgrade first.
Can I file electrical permits over the counter in Manhattan Beach? For simple scopes like a panel swap with a clean load calc and single-line diagram, often yes. Anything bundled into a larger remodel goes through the standard 6 to 10 week plan check.
How long does an Edison service upgrade actually take? We see 8 to 14 weeks from application to energization. Underground conversions and transformer capacity issues can push longer. File early and in parallel with the city permit.
What is the permit fee for a panel upgrade? The city publishes "$220 + inspection" for an electrical panel upgrade. That is the city side only. Edison fees and the contractor scope are separate.
Is my 100A panel enough for an EV charger and a heat pump? Usually no, especially with an existing electric range or dryer in the load. CEC Article 220 load calc gives the real answer. We run it before we quote the work.
