MINOR

This bill expands the types of water heating systems that qualify for building permits in new single-family homes by adding heat pump water heaters alongside solar water heaters. The change allows homeowners to use more efficient electric heat pump technology as an alternative to solar systems, providing greater flexibility while still promoting energy efficiency. The effective date remains July 1, 3000, which appears to be a placeholder date.

Scope change

The bill's scope remains focused on new single-family residential construction, but the eligible water heating technologies have been expanded to include heat pump water heaters in addition to solar water heaters.

ELIGIBILITY

Added heat pump water heaters as an eligible alternative to solar water heaters for new single-family residential construction permits
