Graywater systems are regulated by state water and plumbing rules, not by one national law. California (Water Code section 14875) and Arizona (Revised Statutes section 49-204) are the clearest verified examples: California's chapter governs construction, installation, or alteration of graywater systems, and Arizona provides that a city, town, or county may not limit residential graywater reuse by rule or ordinance unless conditions are met. Local permits, plumbing codes, and HOA rules may still apply.

In most states, recorded covenants and association rules usually control and a clothesline ban may be enforceable — but Florida and Utah have verified statutes that protect clotheslines, and Hawaii's frequently cited statute covers solar devices only.

Usually yes: an association may regulate where and how owners compost through the governing documents and architectural review, and the official sources reviewed for California and Vermont did not identify a specific protection for backyard composting. Municipal organics programs such as Seattle's required food-and-yard collection and California's SB 1383 obligate cities and properties to arrange collection, not to permit a personal bin.

The federal sources reviewed do not identify a residential landscaping protection. Protection depends on your state: Colorado, Texas, Florida, and Nevada are verified examples that restrict HOA bans, while each still allows design review, aesthetic standards, and some limits.

Drainage and mosquito control around a home are mostly the property owner's job: water that falls on your roof and yard is yours to manage, overflow from rain barrels and gutters must be directed away from buildings, and standing water that breeds mosquitoes is something health agencies expect you to eliminate. The exact rules come from local drainage codes and health departments, with a few state laws like Colorado's residential rainwater collection statute.

Read three documents in order — the declaration (CC&Rs), the bylaws, and the board's rules — and remember that state statutes can override all of them. Request current copies in writing, then check architectural review, exclusive-use areas, common elements, maintenance, and insurance provisions.

Colorado homeowners may collect rooftop precipitation in up to two rain barrels with a combined capacity of 110 gallons or less, used for outdoor purposes on the property where collected — no permit is required. The water cannot be used for drinking or indoor household purposes, and common interest community associations may not prohibit such barrels, though placement and aesthetic rules may still apply.

Colorado law bars HOAs and other common interest communities from prohibiting xeriscape, nonvegetative turf grass, or drought-tolerant landscapes as ground cover — for attached single-family homes under C.R.S. 38-33.3-106.5(1)(i)(I)(A) and for detached single-family homes under the broader (1)(i.5) — while still allowing design guidelines, review, and reasonable limits. Rain barrels are protected separately.

The official sources reviewed for Texas identify a state-level statute, agency, or utility source relevant to water-saving landscaping. That does not by itself approve the project: the exact section, property type, local authority, utility process, and governing documents still have to be checked.

Texas Property Code §202.007 generally prevents a property owners' association from banning or restricting an owner's rain barrel or rainwater harvesting system. The protection is conditional: location, visibility, color, materials, common property, local rules, plumbing, drainage, and the association's statutory exceptions still matter.
