What to provide
Have the property address, parcel number, owner name, and approximate installation year if known. Older records may be indexed differently or may not be digitized.
Use records as a starting point
A historical sketch can help locate components, but field conditions may have changed. For a purchase or construction project, confirm the actual system location and condition.
What to verify locally
Permitting, inspection, setbacks, acceptable system types, professional licensing, and design requirements are controlled by state and local authorities. If your question affects construction, a property purchase, a repair, or drinking-water safety, confirm the answer with the local health/environmental department.
