Summary
Rainwater harvesting is fully legal in Tarrant County. Texas Property Code 202.007 prohibits HOAs from banning rainwater systems, though HOAs may set reasonable aesthetic standards. State sales tax exemption applies.
Sec. 202.007. CERTAIN RESTRICTIVE COVENANTS PROHIBITED. (a) A property owners' association may not include or enforce a provision in a dedicatory instrument that prohibits or restricts a property owner from: (1) implementing measures promoting solid-waste composting of vegetation, including grass clippings, leaves, or brush, or leaving grass clippings uncollected on grass; (2) installing rain barrels or a rainwater harvesting system; (3) implementing efficient irrigation systems, including underground drip or other drip systems; or (4) using drought-resistant landscaping or water-conserving natural turf. (b) A provision that violates Subsection (a) is void.
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.
