Rainwater laws / Alabama
Is it legal to collect rainwater in Alabama?
Checked at Alabama's own statutes and agencies, November 2026. Not legal advice.
No state law found
We found no Alabama law about collecting rain from your roof, so no state rule limits a rain barrel for the garden.
What we checked
We searched Alabama Code and Administrative Code, ADEM and ADECA sites for anything on collecting rain from a roof and found nothing. That means no state rule we could find limits a rain barrel, not that none exists.
Before you buy a big tank
State law is only one layer. Cities and counties can set their own rules, especially for tanks plumbed into the house, and an HOA can limit where a barrel sits. Drinking rainwater needs treatment everywhere. For a barrel or two on a downspout for the garden, the state rule above is usually the one that matters.
