Full Breakdown

Tarrant County does not regulate rainwater harvesting on private property. Texas Property Code Section 202.007 explicitly preempts HOA bans on rainwater collection systems and solar devices, meaning HOAs cannot prohibit residential rain barrels or cisterns. HOAs may impose reasonable screening and aesthetic standards such as requiring barrels to match the house color or be hidden from street view, but they cannot outright ban them. Texas Tax Code Section 151.355 exempts rainwater harvesting equipment from state sales tax when purchased for on-site collection. Systems used for potable (drinking) water must comply with Texas Health and Safety Code Chapter 341 and require TCEQ oversight, including first-flush diverters and disinfection. Non-potable landscape use systems need no permit. Contact the Texas A and M AgriLife Extension in Fort Worth for design assistance.

Violations & Fines

No county rainwater harvesting violations exist. HOA overreach beyond TX Prop Code 202.007 limits can be challenged civilly by the homeowner. Unapproved potable systems may violate TCEQ rules.
