If a Cedar Rapids, Iowa sewer tap book and plumbing card show different dates, first ask which side of the service line and which event each date describes. The City’s sanitary service research procedure distinguishes the public tap connection from private-side plumbing records. It says a private-side permit can follow the tap by as much as about a year, while an old tap-book entry may record a later replacement. Neither date alone establishes when the entire present line was installed.
Match the date to the record
- Tap Books (roughly 1910s–1990s): Ask for the handwritten tap entry, any replacement notation, and the lot or cross-street reference used before today’s address.
- SanTap (roughly 1990s–2015): Ask for the service tap entry and its event date, and whether it overlaps an older book entry.
- Building Services plumbing card (roughly 1960s–2015): Ask for the private-property-side permit or card date and the work it actually authorized.
- EnerGov (roughly 2015 onward): Ask whether the later permit or service record describes a new connection, private work or replacement.
These are the City procedure’s research eras, not promises that every address has a record in each system or that the public can search them. The document is a staff procedure with internal links. Do not treat those links as a public portal. For a newer building-permit clue, the separate public Building Permit Viewer searches by permit number, address, contractor and status. Its results are limited to 50 records, so narrow the criteria if the page reaches that limit. The viewer is a preliminary permit search, not a public Tap Book, SanTap or plumbing-card index. Our permit lookup by address guide explains why a historical lot description may matter when a current address fails.
Ask for the underlying record, not just a date
Give the City the present address, any former address or lot description, approximate work period, and the two dates or record references that conflict. Ask it to identify the original tap entry, any replacement entry, and the private-side plumbing card or permit, including what each date means. The procedure cautions that a replacement can change an old book’s displayed date and that a corner-lot service may be filed under a cross street. Ask the custodian to search those keys if the first address returns nothing.
For a Building Services plumbing card or permit file, the department publishes a Public Information Request form with an Address and/or File # field and a listed email submission route. For Public Works tap-book or SanTap material, use the City’s My CR inquiry entry under Sewer & Storm Water to ask which custodian can provide historical sanitary-service records and how to make that records request. My CR explicitly permits an inquiry without creating an account; it is not itself proof that an archival tap record will be supplied online. Name the records and dates you need so the two offices can route the question instead of assuming one file contains all four eras.
Reading a plumbing permit in the City’s viewer
The viewer sorts each permit into one of five statuses: Pending Review, Issued, Expired, Closed or Void. For a sewer-line question they mean different things:
- Closed: the City’s file on that permit is finished. Ask whether a final inspection is recorded before you read it as approval.
- Issued: work was authorized, but the permit was still open when the data was pulled.
- Expired: the permit lapsed. It shows that work was authorized at one point, not that it was inspected.
- Void: the permit was cancelled. Don’t count it as evidence that the work happened.
- Pending Review: an application not yet issued.
Filter by the plumbing contractor’s name when you know who did a repair; it often finds a permit faster than an address that changed. Building Services answers permit questions at (319) 286-5831 (option 1, then 1), Monday through Friday from 7:30 a.m. to 4:30 p.m.
What the comparison can and cannot settle
A tap entry and a plumbing card may document different parts of the same job, but a later date can also reflect a replacement. Record any notation about the work, the mapped lot or cross street, and whether the date is an installation, permit, update or replacement. If the City cannot locate a card in its period of coverage, ask which other source it checked before concluding the work lacked authorization. Our no-result guide covers that evidence limit. If you need to know whether a permit was finalized, request the inspection outcome separately; a plumbing-card date alone does not show final approval.
The historical records do not establish today’s pipe material, location or condition. The City procedure points to field investigation such as CCTV for condition questions, which are different from a paper-history request.
