Title 24 planning in San Mateo County
Preparation guidance for energy compliance documentation on projects in San Mateo County. Requirements are set by the Energy Code and enforced by your local building department.
Hypothetical example / San Mateo County
Remodel adding a heat pump water heater
Suppose a remodel replaces a gas water heater with a heat pump water heater in a garage. Considerations include space, airflow, condensate and electrical capacity. Ask the reviewer about local requirements affecting water heater choices and whether forms are needed for the replacement. Some heat pump water heaters need a dedicated circuit, a certain room volume or ducted air, and the garage location should allow service access. Writing these requirements down before choosing a model avoids a mismatch between the documentation and what physically fits.
Illustrative scenario only; not a statement about local projects, climate or permit rules.
Scenario checklist
- Measure the installation space
- Check electrical capacity
- Plan condensate disposal
- Ask about local requirements
