Title 24 planning in Mariposa County
Preparation guidance for energy compliance documentation on projects in Mariposa County. Requirements are set by the Energy Code and enforced by your local building department.
Hypothetical example / Mariposa County
Vacation rental built from a kit
Imagine an owner assembling a kit home intended as a short-term rental. Kit suppliers sometimes provide energy figures, but those may not reflect the site, orientation or current code cycle. Gather the manufacturer specifications for wall panels, roof panels and windows, and have documentation prepared for the actual installation. Ask the supplier for tested assembly values where available. If the rental will have separate owner storage, mark whether it is conditioned, and confirm hot water and heating sizing reflects realistic occupancy rather than guesswork.
Illustrative scenario only; not a statement about local projects, climate or permit rules.
Scenario checklist
- Collect kit wall, roof and window specs
- Request tested assembly values
- Confirm site orientation
- Do not rely on generic supplier energy claims
