Title 24 planning in Marin County
Preparation guidance for energy compliance documentation on projects in Marin County. Requirements are set by the Energy Code and enforced by your local building department.
Hypothetical example / Marin County
Remodel where electrification rules may apply
Consider a substantial remodel where the owner prefers to keep a gas range but replace the furnace. Some local jurisdictions have adopted ordinances affecting fuel choices in certain projects. The first step is to ask the reviewing agency whether any local reach code applies to the scope, and at what thresholds. Equipment decisions should follow that answer rather than precede it. Keeping a short written record of the reviewer's answer, with the date, helps if questions resurface at plan check or if the team changes during the project.
Illustrative scenario only; not a statement about local projects, climate or permit rules.
Scenario checklist
- Describe remodel scope and square footage
- Ask about local reach codes and thresholds
- List appliances to keep or replace
- Delay purchases until requirements are confirmed
