Finding official records

Responsibility questions get resolved by documents far more often than by argument. The documents are usually held by two or three offices, and asking for them by name works considerably better than asking whose problem it is.

What this page cannot establish

records may be incomplete or absent, especially for older connections
a record shows what was documented, not the current condition
no record found does not establish that no record exists
interpreting a recorded interest is a legal question

Records worth asking for by name

Not every office holds every one of these, and some hold none. Asking specifically tells you quickly which apply.

the connection record or tap card for the address
system mapping showing the main and, if held, the service connection
the published rule or ordinance describing the responsibility boundary
the permit history for the address
any prior inspection or work record the authority holds
the recorded plat and any easements affecting the parcel
the property disclosure from the most recent transaction

What to do with what you get

Record who supplied it, when, and in what form. A responsibility argument two months later turns on exactly that: not what someone said, but what office said it, on what date, and whether it is written down.

Record what you were told does not exist, too. "The authority holds no connection record for this address, confirmed by name and date" is itself useful evidence, and it is different from not having asked.

What each record can carry

Utility map or responsibility document

A record from an operating authority showing routes or stating responsibility.

Reliably shows: what the authority’s own record shows, as of its date. This is the document that can move a responsibility question from unknown toward established. Nothing a contractor says substitutes for it.

Cannot establish: the precise position of a buried pipe; that the record is complete or current; a boundary for any other address.

Permit record

An official record that work was permitted.

Reliably shows: that a permit was issued for a described scope on a date. Permit records are held by an office rather than by a contractor, which makes them durable in a way that private paperwork is not.

Cannot establish: that the work matched the permitted scope; that the work was performed well; that no other work occurred without a permit.

Municipal or utility notice

A letter or notice issued by an operating authority.

Reliably shows: what the issuing office stated in writing on a date. The exact wording governs. Summaries of notices — including a contractor’s summary — regularly differ from what the notice says.

Cannot establish: that the notice is correct as applied to your property; what the consequences of the deadline are; that the described work is your responsibility.

Property disclosure

A statement made during a transaction about known property conditions.

Reliably shows: what was stated at the time of the transaction. A disclosure records what was known and said at a point in time, which can matter well after the transaction closes.

Cannot establish: that the statement was complete; the condition of the line; that undisclosed work did not occur.

What would change the answer

your address and, where relevant, the parcel identifier
the identity of the body operating your sewer system
any prior permit or work records you already hold

What to do next

Asking for specific records by name produces better results than asking a general question.
