Los Angeles FAQ
Can I install a gas range in a new house?
No. The LA all-electric ordinance bans new natural-gas plumbing in residential and most commercial occupancies; induction cooktops and heat-pump appliances are required substitutes.
Does the rule cover renovations?
It applies to new buildings and additions creating a new dwelling unit. Like-for-like replacements and renovations under existing permits remain on prior code.
Norwalk FAQ
Does CALGreen apply to small remodels?
Most mandatory measures apply only to new construction and additions over 1,000 sq ft. Minor kitchen and bath remodels need only the low-flow fixture replacement when fixtures are changed under CALGreen 4.303.
Has LA County adopted an electrification reach code?
Several unincorporated areas adopted reach codes requiring all-electric new construction or solar-ready provisions beyond CALGreen. Check Title 31 amendments and LACoDPW reach-code guidance for the specific community before designing gas appliances.
