California Electrical & Panel Upgrades.
LA electrical — 200A panel upgrades for ADUs + EV, full home rewires, sub-panels, Tesla Wall Connectors. LADBS permit + LADWP coordination.
Bay electrical — older knob-and-tube + cloth-wire homes need full rewires. PG&E coordination, panel upgrades, EV chargers, solar interconnect.
Los Angeles
$3.5K – $25K
EV charger bottom; full rewire + panel top.
Timeline — 1 day EV charger; 1–2 weeks full rewire.
Los Angeles Electrical & Panel Upgrades →San Francisco Bay Area
$4.5K – $35K
PG&E coordination and SF rewire complexity lift cost.
Timeline — 1–2 days EV; 2–3 weeks full rewire (older homes).

Permits look different in LA vs the Bay.
Los Angeles — permit notes
- LADBS permit + LADWP service.
- Load calc per CEC.
- EV charger separate permit.
- Inspection before energization.
Bay Area — permit notes
- City permit + PG&E.
- Load calc per CEC.
- Solar + battery interconnect separate.
- PG&E lead time 4–12 weeks.
How we think about electrical & panel upgrades.
Structural work is the most expensive thing you can do badly and the cheapest thing you can do right. A correctly engineered shear wall, hold-down, or beam costs a few hundred dollars more than the wrong one and protects the building for its remaining life. We refuse to deviate from a stamped engineer's calc — the engineer's stamp is what protects the homeowner in a claim, not the contractor's experience.
California's seismic code has changed dramatically since 2010 and again since 2020 — most homes built before 1980 carry latent risk we can correct in a single retrofit pass. We treat foundation, framing, and shear as one system, never as separate trades.
The schedule, written out.
Week 0
Engineering site visit
Licensed structural engineer reviews existing, soils, slope, snake-camera at foundation cracks.
Week 1–4
Engineering + plans
Stamped calcs, framing plan, hold-down + shear schedule, foundation detail.
Week 4–8
Permit
City structural review — usually faster than full ADU plan check.
Week 8–10
Foundation + shear access
Selective demo, crawlspace prep, excavation if underpinning.
Week 10–14
Install
Anchor bolts, hold-downs, shear panels, cripple-wall bracing, structural framing, beam install.
Week 14–15
Inspection
Inspector verifies every hold-down and shear-nail pattern — common rejection point if subs cut corners.
Materials & assemblies.
| Component | Default spec | Why |
|---|---|---|
| Anchor bolts | 5/8" Simpson Titen HD or equivalent epoxy-set, 7" embed minimum | Old square-washer ½" bolts are not enough; full retrofit upsizes them. |
| Hold-downs | Simpson HDU or PHD with stamped placement at all shear-wall ends | Placement is the failure mode — wrong stud or wrong end = no hold-down at all. |
| Shear panels | 15/32" structural-1 sheathing, 8d common nails @ 4"/12" or per calc | Air nails at the wrong PSI under-drive — every nail must be flush, not over. |
| Beams (LVL / PSL) | Engineered lumber per calc, with stamped connection hardware | Field-fabricated steel saddles are a frequent failure point — only use stamped connectors. |
| Foundation repair | Helical piles, push piers, or wide footings depending on soil + load | Choice is geotech-driven, not contractor-preference. |
Hidden costs we flag up front.
| Line item | Range | When it hits |
|---|---|---|
| Soils / geotech report | $4K–$12K | hillside, expansive clay, or new addition load |
| Excavation + shoring | $8K–$40K | underpinning a settled foundation |
| Plumbing + electrical re-route | $2K–$10K | foundation work cuts through existing services |
| Temporary support | $2K–$8K | interior shoring for beam install |
cheaper alternatives
What we'd consider — and what we wouldn't.
Brace-only retrofit (no bolt-down)
Half the cost but only addresses cripple-wall, not sill movement — incomplete protection.
Carbon-fiber wall repair
Works for crack stabilization but doesn't add capacity for new load.
Owner-permit structural work
Not legal in most CA jurisdictions for residential — requires licensed contractor + engineer.
pitfalls — takeover-job patterns
Mistakes to avoid.
- Pulling a permit without an engineer's stamp — almost every city now requires it for shear / beam / foundation
- Cutting a notch in a joist or beam to fit plumbing — single most common code failure on rough inspection
- Skipping the cripple-wall bracing on a pre-1980 raised foundation — biggest cost-to-benefit retrofit available
- Believing 'the inspector will catch it' — the inspector verifies what's exposed, not what's already buried

In short.
- Cost to upgrade to 200A in LA?
- $3.5K–$6.5K typical. $8K+ if mast or meter relocates.
- EV charger install cost?
- $1,200–$2,500 with permit. Tesla Wall Connector + 60A breaker.
- 200A upgrade cost in the Bay?
- $5K–$9K. PG&E coordination adds 4–12 weeks.
- Cost to rewire a 1920 SF home?
- $20K–$35K depending on access and wall finish.
