Service areas, enrollment and eligibility are set by each administrator and change over time. For ESA, start with the page of the utility that serves your building. Federal tax rules also change; check the IRS pages for the current rules.

Eligibility by property type

  • Market-rate apartments: regional energy network programs are the usual starting point, where your building is in their area.
  • Condominiums and HOAs: some programs treat common areas and individual units differently. Ask how ownership affects eligibility.
  • Income-qualified and deed-restricted housing: the ESA and CSD programs are aimed at these properties and usually need proof of resident income or a regulatory agreement.
  • Federal tax incentives: 179D and 45L each have their own building-type and project rules. Check the IRS pages with your tax adviser.

Affordable and income-qualified tracks

Affordable housing owners often have more options, but also more conditions: income documentation, procurement rules and coordination with lenders and regulators. See affordable housing retrofits for how to turn a capital needs assessment into a scope these programs can fund.

Using programs in a retrofit plan

Treat any incentive as a separate assumption until it is reserved in writing. Keep a version of the plan that works without it. For which building to start with, see California energy benchmarking.

Questions before you begin

Can I combine programs on one project?

Sometimes. Each program sets its own rules on combining with other funding, eligible measures and procurement. Confirm with every administrator before you assume two offers stack.

Does this list cover every California program?

No. It lists whole-building multifamily programs and federal tax incentives. Some local governments, community choice aggregators and municipal utilities run their own programs, so ask the utilities that serve your building too.

Free, no-obligation assessment

Check which programs may apply

The assessment is free and comes with no obligation. Tell us about the buildings and the upgrades you are weighing; two short steps, and engineering records can come later.

  1. We review the buildings, systems and timing you describe.
  2. We check which incentive programs may be open for the property.
  3. With your consent, a qualified California contractor partner contacts you to arrange the free assessment and a quote.
