Full Breakdown
Texas actively promotes rainwater harvesting, and Galveston County imposes no county permit or ban on residential systems. State law protects installations: Property Code 202.007(a) prohibits an HOA from enforcing any covenant that bars a property owner from installing rain barrels or a rainwater harvesting system, and any such provision is void. An HOA may still set reasonable rules on size, type, and location if they do not prevent an economical installation. Equipment is also exempt from state sales tax under Tax Code 151.355. Large systems tied into a public water supply must follow Health & Safety Code Ch. 341 backflow rules.
Violations & Fines
There is no county penalty for harvesting rainwater. An HOA that enforces a flat ban acts on a void provision. Improper cross-connections to city water can be cited by the utility under state plumbing rules.
