Michigan places no statewide restriction on collecting rainwater, and Ottawa County has no rule against it. Residents may harvest rooftop rainwater in barrels or cisterns for lawn and garden use. No county permit is required for typical residential rain barrels.
Unlike some western states, Michigan does not restrict rainwater capture, and neither Ottawa County nor its townships regulate residential rain barrels. Homeowners commonly collect rooftop runoff for irrigating gardens and lawns, which also supports the county's stormwater and water-conservation goals. There is no county rule here; any limits would come only from a subdivision or HOA covenant, or from your city if a large cistern needs a plumbing or structural permit. Do not connect harvested rainwater to your potable plumbing without a cross-connection review. For large-scale or drinking-water use, consult Ottawa County Public Health.
None for ordinary residential rain barrels. Improper cross-connection to potable plumbing can violate the state plumbing code and be ordered corrected by the local building department.
