Hypothetical example / Contra Costa County
Kitchen remodel that relocates the water heater
Suppose a kitchen remodel moves the water heater from the garage to an interior closet and considers switching to a heat pump water heater. Relocation and fuel change can raise questions about venting, condensate, electrical capacity and documentation. Before choosing a model, ask the contractor about space and airflow requirements for the unit and ask the reviewer which water heating forms are expected. Kitchen lighting may also be part of the alteration scope.
Illustrative scenario only; not a statement about local projects, climate or permit rules.
Scenario checklist
- Note existing and proposed water heater locations
- Check panel capacity for electric options
- List new kitchen lighting fixtures
- Ask which forms cover water heating changes
