Start with the complaint date. Buffalo’s Public Data inventory lists one 311 dataset for July 2008 through May 2024 and another for May 2024 to the present. Because both labels include May 2024, check both periods for a request from that month. Preserve the request’s date, type, agency, and identifier before looking for a later inspection or violation.
The City says DPIS answers 311 requests with the Housing type. A Housing request records a complaint pathway. It does not by itself prove that an inspection occurred, a Code Violation was issued, or a building permit was required.
Keep the two 311 periods visible
Use the official older July 2008–May 2024 dataset and the current May 2024–present dataset as separate sources. The City identifies them as whkc-e5vr and 3tj7-3tdz.
The City’s instructions describe an Actions Query Search using a street address. Search each dataset separately for a request from May 2024.
For each row you actually find, copy:
- Dataset period and dataset identifier.
- Street address exactly as displayed.
- Request date and record type.
- Responding agency.
- Request or case identifier.
- Status or outcome wording exactly as shown.
Do not merge two similar rows until their identifiers, dates, and record types support the match.
Complaint, inspection, and violation are separate records
The same City page describes General Inspections separately from issued Code Violations. A General Inspection can carry its own outcome, including no action, a letter, or a referral. The Code Violations dataset covers issued violations from March 28, 2016. That date belongs to the violation dataset, not to all complaints, inspections, or permits.
Build one line for each object:
- 311 Housing request: what was reported and when the request entered the service system.
- General Inspection: the inspection event and its recorded outcome.
- Issued Code Violation: the separate violation record, when one exists.
- Building permit: the construction authorization and status in the permit record.
The Buffalo building-permit guide explains the permit dataset and its publication lag. If a complaint or inspection supplies a permit number, keep that identifier in the issuing system with the permit-number lookup guide.
What each Buffalo dataset covers
The Public Data page and the City's open data guide give each record family its own span and fields:
- 311 requests: July 2008 to May 2024, then May 2024 to the present, in two datasets.
- Code Violations: issued violations from March 28, 2016, updated every two weeks. Each row carries a case number, date, case type, address, SBL (the parcel identifier), the code section violated and an active or closed status.
- Permits: all permits issued from January 2, 2007 to the present, minus the most recent two weeks.
The code section and status fields are the most useful for a complaint question. A closed violation with a code section tells you what the City cited and that the case ended, without saying how it was fixed; for that, look for a permit in the same period or ask for the case file.
For a one- or two-family rental, check one more record. The City's rental registration page says all non-owner-occupied single- and two-family homes must register, a program that began in January 2005, and that certificates of occupancy are denied where a lead paint hazard exists. A housing complaint at a rental often leads to that registration file.
Reconcile a May 2024 mismatch without inventing a join
Imagine a fictional Housing request dated in May 2024. It appears in one 311 period, while a General Inspection under the same address appears later with a letter outcome. No issued violation identifier is shown, and a separate permit record predates both.
Record those four facts as four rows. The address and sequence make a relationship worth checking, but they do not create an automatic database join. Ask whether the inspection record names the 311 request, whether a violation number was issued, and whether the permit concerns the same work.
This approach also handles duplicate-looking May records. Keep both until the request identifier or agency record shows whether one is a migrated copy, a continuation, or a different complaint. Do not presume any of those outcomes before the identifiers settle it.
Ask for the exact missing object
To file a new complaint rather than research an old one, call 311 inside city limits or 716-851-4890, or use the online self-service portal on the 311 Call & Resolution Center page. The Department of Permit & Inspection Services is in City Hall, 65 Niagara Square; its department page lists 716-851-4972, a FOIL line at 716-851-4921 and Rental Registration at 716-851-5621, and says Tuesday and Thursday permitting visits have been by appointment since October 1, 2025.
If the appropriate dataset does not supply the needed record, use Buffalo’s linked FOIL request route for a named existing record. Provide the street address, approximate date, request or case number if known, record class, and the exact missing item: the 311 request, General Inspection outcome, issued Code Violation, or related permit reference.
A blank or unavailable public result does not establish that no complaint, inspection, violation, or permit record exists.
A complaint record does not prove permit issuance, inspection approval, occupancy approval, or present property condition. An inspection outcome is not automatically an issued violation, and an issued violation is not a permit final. Keep the objects separate until their dates and identifiers connect them.
