Is Your Electrical Panel Big Enough for a Modern LA Remodel 2026?

Many LA homes still run on 100 amp panels. Modern remodels with heat pumps, EV chargers, and induction ranges often require 200 amp upgrades.

Why this matters in December

Homeowners plan electrical upgrades now to avoid summer overloads and permit delays.

Why Panels Are Failing Modern Remodels

Electrification changed everything.

Common additions:

• Heat pump HVAC

• Induction cooking

• EV chargers

• Electric water heaters

Old panels were not designed for this load.

What 100 Amp Panels Can Handle

Typically:

• Basic lighting

• Gas appliances

• Limited HVAC

Add modern systems and capacity is exceeded.

How Load Calculations Work

Electricians calculate:

• Existing loads

• Proposed equipment loads

• Demand factors per code

If total exceeds panel rating, upgrades are required.

Title 24 and Electrification Pressure

California encourages electric systems. Permits increasingly flag undersized panels during plan review.

Panel Upgrade Options

• 125 amp upgrade in limited cases

• 200 amp standard upgrade

• Subpanels when service allows

Utility coordination is often required.

Cost Ranges With Assumptions

Assumptions: Single-family home, accessible service.

• Panel upgrade: $4,000–$9,000

• Service upgrade with trenching: $8,000–$15,000

Hillside lots and older neighborhoods increase cost.

Neighborhood Notes

• Pasadena: Older services common

• Sherman Oaks: EV demand rising

• Irvine: HOA coordination required

FAQ

Can I keep a 100 amp panel?

Sometimes, but many remodels exceed capacity.

Does Title 24 require upgrades?

Indirectly, yes when electrification increases load.
