Bay Area attic insulation rebate programs, checked one by one

Where things stand on October 23, 2026

If you were hoping for an attic insulation rebate that covers part of the job, here's the plain answer first: for a typical Bay Area homeowner paying for insulation on its own, there isn't one right now. The money that does exist is tied to heat pumps, and it depends on which utility sends your bill.

Every amount on this page comes from the program's own website, checked on the date next to each row. We left out anything we couldn't confirm there, so if a program you've heard of is missing, that's why. Rows group into three piles: open only with a heat-pump project, no insulation rebate open to every customer, and ended. Income-qualified programs are outside this page.

The open rebates, read closely

San José Clean Energy's EcoHome rebate lists attic insulation as add-on equipment that "must be paired with a HP-HVAC rebate." A heat pump water heater alone doesn't unlock it. The program wants your rebate application approved before installation begins, photos before and after with a ruler showing depth, and proof of final permitting. On contractors, the program's FAQ says you can choose any contractor, as long as no labor violations have been filed against them in the last three years.

City of Palo Alto Utilities pays its attic and roof insulation rebate only "with a core appliance rebate," which on the Rebate Hub means a heat pump water heater, heat pump HVAC system or induction cooktop or range. The order matters: you reserve funds before installing, then send invoices and proof of permit inspection within 90 days of the final inspection.

One detail is easy to miss. Palo Alto's rebate asks for R-30 in an attic, but the rebate's minimum isn't the code's. Palo Alto and San Jose are both in climate zone 4, where the 2025 Energy Code asks for R-49 when an attic ceiling is altered, unless an exemption applies. Our Title 24 page has the zone 4 rules.

Silicon Valley Clean Energy (Cupertino, Milpitas, Mountain View, Sunnyvale)

SVCE's Full-Service Home Upgrades page lists an "Electrical & Efficiency Improvements" rebate of up to $2,000 alongside its heat pump rebates, for single-family homes up to a fourplex with existing gas equipment that install at least one heat pump. The page doesn't say which measures that line covers, and it doesn't mention insulation. It also says "all participants must use an SVCE partner contractor." Because we can't confirm from SVCE's own page that attic insulation counts, it isn't in the table. Ask SVCE directly before planning around it.

Silicon Valley Power (Santa Clara)

Santa Clara's city-owned utility lists an "Insulation Add-on rebate: $1.00/sq.ft. up to $5,000" on its Residential Heat Pump HVAC Rebate Rules page. Like the others, it rides on a heat pump: the main rebate requires replacing an existing gas, propane, oil or wood furnace, or electric resistance heat. The add-on asks for attic insulation of R-44 or more, with the rating on the receipt, and proof of the building permit final, and the application is due within 60 days of that final. SVP's rules also say DIY installs aren't eligible and the installation must be done by a licensed contractor. SVP says its measures and amounts are subject to change, so confirm with SVP before you buy or install anything.

Ended: the two programs people still quote

BayREN's insulation rebate was the regional standby for years. BayREN's own page now says: "This rebate is no longer available as of August 2024." Its broader Home+ program followed: "As of October 18th, all incentives and Energy Advisor services through the Home+ program are no longer available," BayREN announced on October 21, 2024.

Plenty of pages still advertise the old per-square-foot figure. If a quote or an article promises it, it's describing a program that closed two years ago.

No insulation rebate for most customers: PG&E and the community energy providers

PG&E's rebates page has nothing for attic insulation. The community choice energy providers we checked put their rebate money into heat pumps, induction, EVs, e-bikes and batteries instead. We checked Ava Community Energy, CleanPowerSF, MCE, WestLight Energy (formerly Peninsula Clean Energy) and Sonoma Clean Power, and none lists an attic-insulation rebate open to every customer. MCE and Sonoma Clean Power also list eligibility-based programs that can include insulation; this page doesn't cover those. In the city of Alameda, Alameda Municipal Power's residential rebates cover heat pumps, panels, EV and e-bike items and more, and none is for insulation.

Federal money

Neither of the federal home-energy rebate programs pays for attic insulation in California right now. The Energy Commission's page says HEEHRA rebates for single-family homes are "fully reserved statewide" as of February 24, 2026, and that they cover heat pumps replacing other heating, not insulation. The same page says the Department of Energy "has not yet approved California to offer HOMES rebates."

The federal tax credit for insulation is a different program, and it ended for work completed after 2025. Our insulation tax credit page quotes the IRS on exactly when.

Before you sign anything

A rebate is the program's promise, not the contractor's. Before you sign a contract that counts on one, confirm with the program that the work and the contractor will qualify. What that looks like here:

• Palo Alto: reserve funds first, then keep the invoices and the permit inspection record.
• San Jose: get the rebate application approved before installation begins, and keep the ruler photos and the final permit.
• Santa Clara: SVP's rules call for a licensed contractor, with the license number on the invoice, a receipt that shows the insulation's R-value, and the permit final. Apply within 60 days of that final.
• SVCE territory: the program says every participant uses an SVCE partner contractor, so start with SVCE, not with a contractor.

Attic WISE isn't a partner of any program on this page, and we don't decide whether a job qualifies; the program does. What we can do is put the R-value, the square footage and the depth in writing on your quote, which is the information these programs ask for. If a heat pump is in your plans, our heat pump guide covers why the attic usually goes first, and the cost page has Bay Area market ranges for the insulation itself.
