Existing Building Reach Codes Working Group: Implementation and Enforcement
- Hybrid: In-Person: Room 101, 455 County Center, Redwood City Virtual: Zoom
Please join San Mateo County, Rincon Consultants, and TRC on Thursday, July 31 at 11am for a working group for building officials, contractors, and city staff. During this working group and webinar, TRC will facilitate a workshop on compliance strategies for three new policy options for existing buildings: • AC to Heat Pump: A policy focused on air conditioning unit replacement. Homeowners choose either to replace an AC unit with a heat pump or an AC unit alongside efficiency measures. • Electric Readiness: A policy that adds wiring near gas appliances during renovations. This allows homeowners to easily electrify gas equipment in the future • Single Family FlexPath: A policy that requires a set of efficiency improvements during substantial renovations. Homeowners choose the efficiency improvements from a menu of options.
