Permit & Policy Shortcuts

  • Use expedited permitting pathways for projects meeting resilience standards (pp. 18–19, 26–27).
  • Bundle rainwater/greywater and PV+storage in one submission; request fee waivers for survivors.
  • Coordinate early with mutual water companies for tank tie-ins and hydrant accessibility.

Tank Sizing Estimator

Calculate recommended water tank capacity for rainwater harvesting, firefighting, and domestic use.

Rule of thumb: gallons harvested ≈ roofArea × rainIn × 0.623 × efficiency. Add fire + domestic reserves.

House / ADU Wildfire Safety Tester

Answer these quick questions about your house or ADU. You’ll get a 1–10 wildfire safety rating (1 = less safe, 10 = safest) and an informal “approval” style status. This is a heuristic tool only; always confirm with local codes.

This tool gives an approximate rating only and does not replace a WUI code review, local fire department inspection, or guidance from a wildfire specialist.
