Knob-and-tube is the blocker—and BayREN’s 2026 rebate helps

Many Willow Glen homes still have knob-and-tube wiring. Insulating over active K&T is a fire risk, so the first step is an electrician’s assessment—not a rushed blow-in.

BayREN’s 2026 EASE Home program offers limited-time help: up to $2,000 to remediate active knob-and-tube wiring, and $300 for certification that wiring is inactive. Rebates apply to qualifying EASE Home projects; you’ll need an electrician’s invoice and inactivity certification submitted to BayREN.
