- $20,000 per-project
- About the amount
- Up to $20,000 per home for energy-related work; up to $4,000 for health and safety on DCEO's page (DOE-funded draft plan states a $2,000/unit health-and-safety cap and $700 incidental-repair limit — say 'up to' since the figures conflict by funding source).
- Housing rules
- Renter households qualify with a landlord consent form; the state rental agreement freezes rent and bars eviction-without-cause for 12 months. Mobile homes eligible; non-stationary campers/trailers without a mailing address are not.
- How long it takes
- Assessment typically within 3 months of approval; contractor work 1-5 days; up to 1 year total from qualifying to finished.
- How to apply
- Pre-apply online through ILogin, or in person at your county's Local Administering Agency.
- Does not pay for
- No roof replacement (limited patching only if budget allows); windows are rarely included. No ramps, grab bars, walk-in showers, or home care.
