Where this page applies
This page covers Tempe addresses in 85284, including Hamilton Homes Tempe, Sierra Tempe and Estate La Colina. These neighborhood names and ZIP associations are listed by ZIP Data Maps; association and postal boundaries can change. Confirm the property address when requesting service.
Hamilton Homes, Sierra Tempe and Estate La Colina
South Tempe's 85284 ZIP includes Hamilton Homes Tempe, Sierra Tempe and Estate La Colina. Warner Ranch is another well-known south-Tempe community. Neighborhood names help orient a service-area search, but a ZIP address does not establish pipe age, material or condition.
Landscaping and long yard runs can complicate a sewer diagnosis. Ask where the cleanout is and whether the camera reached the connection toward the main. A technician should locate any defect before recommending excavation, lining or a change to the yard.
Buying a home in south Tempe
A normal home inspection may not include a sewer camera pass. If a seller reports repeat drain service, ask for records and consider a separate sewer scope during the inspection period. Request the video, the accessible length inspected, and a written explanation of any section the camera could not reach.
Confirm your utility jurisdiction
ZIP boundaries are postal boundaries, not a map of city wastewater responsibility. At an edge-of-city address, check the utility bill or ask the utility which agency owns the public main. Tempe's homeowner guidance applies to property served by Tempe's wastewater system; do not assume another jurisdiction follows the same rules.
Private line or city main?
The City of Tempe says homeowners are responsible for the sewer service line running from the home to the city main. If several nearby properties back up together, notify the utility as a public-main issue may be involved. See the service-line responsibility guide and the city's homeowner information. For an individual backup, stop using water and note which fixtures are affected before calling.
Next steps for a 85284 property
- Explain whether one fixture or several are affected and whether water is entering living space.
- Find any accessible cleanout, and share prior cleaning or repair records.
- Ask for a clear finding, the proposed scope and price before approving repair.
For urgent symptoms, read what to do during a sewer backup. If problems recur, a camera inspection may help identify the location and cause.
