House OIG
Documented here as an active federal OIG office, even though it is not a CIGIE member office.
Research methods
How this site classifies, sources, and dates OIG profiles.
InspectorGeneral.net is a public scholarly reference for the federal Inspector General system. This page explains the site-wide rules used for counts, classification, sources, dates, leadership, vacancy measures, and law enforcement authority.
Count and roster reviewed: September 26, 2026
Method summary
A public count, not an internal roster.
InspectorGeneral.net uses an active standing OIG count for its headline number, not an internal government roster. Historical offices, temporary special IGs, special-purpose designations, and oversight-system institutions are documented separately. When sources disagree or provide only approximate dates, the uncertainty is described rather than hidden.
What counts and what does not
The headline number is an active standing OIG count.
| Category | Short definition | Counted? | Examples |
|---|---|---|---|
| Active standing OIG office | A current Office of Inspector General with ongoing institutional existence. | Yes | NASA OIG, USDA OIG, TIGTA, House OIG. |
| Historical OIG office | A former OIG office that no longer operates as a separate office. | No | FEMA OIG, CDFI Fund OIG, USIA OIG. |
| Temporary or special IG office | A special-purpose office created for a limited program, conflict, emergency, or recovery effort. | No in the active standing count | SIGAR, SIGIR, SIGTARP, SIGPR. |
| Special-purpose IG role or designation | A role or designation tied to existing IG structures rather than a permanent standalone OIG office. | No | SIGOAR. |
| Oversight-system institution | A council, committee, data platform, integrity mechanism, or training body that supports the IG community. | No | CIGIE, PRAC, PCIE, ECIE, Oversight.gov, Integrity Committee. |
| Pending or proposed office | A proposed office that has not yet been enacted and operationalized. | No unless enacted and operational | Proposed IG for Fraud, Accountability and Recovery. |

Historical cohorts
Original 1978 offices are identified by the IG Act's named list.
The original 1978 cohort means the twelve departments and agencies named in the Inspector General Act of 1978. Pre-1978 statutory offices, including HHS OIG and DOE OIG, are treated as predecessor or cohort-adjacent offices rather than as offices newly created by the 1978 Act.
Combined offices are counted once. Historical, transferred, abolished, merged, and sunset offices are documented in the directory when they matter to the system's history, but they are not included in the active standing count. Source counts may differ because statutory lists, CIGIE membership lists, directories, and historical inventories count different things.
Legacy offices
FEMA OIG and CDFI Fund OIG are historical or statutory legacy entries, not active standalone offices.
Institutions and special roles
PRAC, CIGIE, and SIGOAR are important to oversight history, but are tracked outside the office count.

Evidence and source limits
Profiles use public sources, strongest first.
Primary legal authority
Public laws, U.S. Code, Statutes at Large, regulations, executive orders, presidential messages, Senate records, and agency orders.
Official OIG or agency records
OIG websites, semiannual reports, biographies, press releases, budget justifications, archived pages, and official histories.
Governmentwide oversight and research sources
CIGIE, Oversight.gov, CRS, GAO, OPM, congressional committee materials, and Federal Register notices.
Contemporary reporting
Used for recent removals, resignations, disputes, nominations, and events not yet reflected in official records.
When sources conflict, the site favors the strongest available source and explains discrepancies when they affect classification, dates, or counts.
Profiles are built from public statutes, U.S. Code text, official OIG and agency records, public congressional materials, governmentwide oversight records, public reporting, and publicly released or declassified materials. They do not rely on classified material, non-public internal records, unpublished investigative records, sources-and-methods information, or operational details.
Dates and uncertainty
| Date type | Meaning |
|---|---|
| Exact date | A full date supported by the cited source. |
| Approximate date | A month, year, or other partial date where the full date is not known. |
| Inferred date | A date derived from related records, such as a successor start date or vacancy report. |
| Statutory date | The date legal authority was enacted or became effective. |
| Operational date | The date an office appears to have begun operating. |
Approximate or inferred dates are labeled rather than presented as exact.
Statutory establishment, operational start, first verified leader, vacancy denominator, and dissolution or transfer dates may differ. Profiles explain those differences when they affect how a specific office is interpreted.
Leadership and vacancy calculations
Confirmed leadership and acting service are tracked separately.
For PAS OIG vacancy metrics, acting, interim, and performing-duties periods usually count as vacancy periods because the office lacks a Senate-confirmed Inspector General. Acting officials are still recorded in leadership tables so readers can see who led the office during those intervals.
Profile vacancy snapshots normally show two cards: the share of elapsed days without a Senate-confirmed Inspector General and the longest vacancy period. Current or ongoing vacancy details are documented in the leadership table or profile methodology notes unless a profile-specific reason calls for a different display.
DFE and non-PAS offices use different appointment and vacancy logic. Those profiles explain office-specific denominator choices, appointment records, or calculation caveats when the general PAS rule does not apply cleanly.
Law enforcement authority
Law enforcement authority is separate from investigative responsibility.
OIGs may investigate without having independent firearm, arrest, or warrant authority. The site codes law enforcement authority by controlling source: direct statutory authority under 5 U.S.C. § 406(f)(3), Attorney General-authorized authority under § 406(f)(1)-(2), separate statutory authority, special statutory authority, or no identified independent authority.
Successor-office authority is not automatically applied backward to historical predecessor offices. Profiles explain law-enforcement classification issues only when the office-specific record requires more than the site-wide rule.
Oversight institutions and non-OIG entities
System institutions are documented outside the OIG count.
Some entities are central to the IG system but are not Offices of Inspector General. InspectorGeneral.net documents councils, committees, data systems, integrity mechanisms, and training institutions separately because they shape how the IG community operates. They are not included in the active standing OIG count.
Directory display
Directory cards are filed by substantive agency name.
The OIG directory is sorted alphabetically by filing name. Leading generic qualifiers such as Department of, Department of the, United States, and U.S. are ignored. Integral lead words such as Federal, National, Securities, and Small Business are retained.
Dated office roster · September 26, 2026
71 active standing federal OIG offices.
As of September 26, 2026, InspectorGeneral.net identifies 71 active standing federal Offices of Inspector General under its office-count rules: 33 establishment OIGs, 30 designated federal entity (DFE) OIGs, and 8 other standing OIGs. This numbered roster preserves that dated population; linked profiles carry their own review dates.
The unit is the office, not its leader or the number of agencies it oversees. An office with an acting leader or a vacant IG position still counts. Combined offices, including the Federal Reserve Board/CFPB OIG, count once. The House OIG is included even though it is outside CIGIE membership.
Why the site previously showed both 71 and 72: the old Active filter included SIGOAR, the Special Inspector General for Operation Atlantic Resolve. That is an additional role carried through existing IG offices, not a separate standing OIG. The headline and the Active standing OIGs filter now both exclude it. SIGOAR remains in All and Special; historical offices, temporary special IG offices, proposed offices, and cross-IG institutions are also outside this standing-office roster.
Source cross-check, September 26, 2026: the CIGIE Inspectors General Directory lists 70 offices that correspond to the roster below. Adding the separately documented House OIG gives 71. CIGIE lists the defense office as Department of War; this site uses Department of Defense for that same office. The FY 2026 Operation Atlantic Resolve oversight plan documents the SIGOAR designation and participating OIGs. The list is alphabetized by office shorthand; each office link opens its profile and supporting sources.
