The Cf 1R Alt 02 form is a compliance tool that California requires for residential alteration projects involving heating, cooling, and duct systems. It applies to specific climate zones (1, 3, 4-7, and 16) and covers a range of energy-related modifications. Before starting your project, check that this is the correct version for your climate zone and the type of work you plan to complete.
This certificate of compliance includes sections for general project information, HVAC system specifications, duct system alterations, and HERS verification protocols. Each section requires accurate data about the equipment being installed, the method of installation, and the energy performance measures in place. A single error can delay your permit approval, so review each field before submission.
If your project involves non-duct HVAC work or falls in a different climate zone, you may need the Cf 1R Alt form or the Cf 1R Alt HVAC form instead. For duct testing documentation, see the duct test form. You can also browse our certificate of compliance forms for other state and local compliance needs.
