A.R.S. 33-1801: Plumbing Responsibility in an Arizona Planned Community

The Planned Communities Act applies to planned communities: neighborhoods where owners hold separately owned lots, and a homeowners association owns and manages the shared common areas. The Act defines that structure. It states its reach plainly:

This chapter applies to all planned communities.

The key point for plumbing is ownership. In a planned community, an owner typically owns the entire lot and the home on it, all the way down. That means the water and drain lines serving only that house, from inside the walls out to where they meet the shared system, are almost always the owner's responsibility, not the association's. The HOA maintains the common areas it owns, such as shared landscape irrigation, a community pool's equipment, or a common drainage feature. This is a real contrast with a condominium, where the association often maintains building-wide plumbing because owners only own the airspace of their unit.

Picture a homeowner in a gated subdivision whose main water line springs a leak in the front yard, between the house and the street. Because the owner owns the lot, that service line is generally the owner's to repair, not the HOA's, even though it runs under "the neighborhood." Compare that to the same leak in a condo, where a shared line would likely fall to the association. The lot-ownership model is why planned-community owners carry more of the plumbing burden themselves.

The controlling detail, as always, is the recorded declaration. The Act lets each community's declaration and CC&Rs assign maintenance duties, and those documents override the general model. A declaration can, for instance, put a shared private street's drainage on the association or hand a specific responsibility to owners.

If you live in a planned community, assume the plumbing that serves only your home is yours to maintain, then check your declaration and CC&Rs to confirm, because they control. Do not assume the HOA covers a buried service line just because it sits outside your walls. In a condo, where owners hold only their unit's airspace, the split follows a different statute; see A.R.S. 33-1247 condo plumbing responsibility. For the related question of responsibility between a commercial tenant and landlord, see commercial plumbing tenant vs landlord, or who is responsible for the sewer line to your home.
