Rainwater Collection Laws In Nevada
Nevada legalized rooftop collection in 2017, and kept it deliberately small: a single-family dwelling, non-potable domestic use, and a de minimis amount the statute never puts a number on.
Statute text checked September 2026. Next review March 2027.
Allowed, with limits worth reading Where the state stands
None Permit needed
No cap Residential volume limit
Not permitted Drinking it
What you can use it for
- Non-potable domestic use at a single-family dwelling
Drinking it: not permitted. Treatment is a separate question from legality, and the answer is on Is Rainwater Safe To Drink?.
Your homeowners association
Nevada has no statute limiting what an association can do about rain barrels, so the covenant you signed is the rule that applies.
The general case is on HOA Rules And Rain Barrels.
What surprises people
- The exemption is limited to the rooftop of a single-family dwelling. Apartments and commercial roofs are not covered by it.
- Use is limited to non-potable domestic use, so drinking it is outside the exemption.
- The statute says de minimis and never defines a gallon figure, which is unusual and means there is no number to point at if anyone asks.
- Nevada is a prior appropriation state, which is the reason a specific exemption had to be written at all. Before 2017 there was no clear authority to capture rain.
- No state limit on rooftop collection
- Allowed, with limits worth reading
- Real restrictions on ordinary collection
