Enacted legislation or regulation · St. Louis only (local rule)

In effect This instrument is recorded as currently in effect as of the dataset date.

Scope

City of St. Louis Ordinance 72181 (Board Bill 49, 2026-2027 session), recommended by the Planning Commission, amends the Zoning Code to add Section 26.77, which the City's official ordinance record describes as comprehensive zoning regulations for data centers. The Board of Aldermen passed it on third reading on 11 September 2026, the Mayor approved it on 17 September 2026, and the City records its effective date as 17 September 2026. It applies only in the City of St. Louis. The specific standards in Section 26.77 are not restated because the ordinance text PDF was not opened.

Summary

The City of St. Louis adopted Ordinance 72181, from Board Bill 49, which adds Section 26.77 to the Zoning Code with zoning regulations for data centers. The Planning Commission approved the proposal on 10 June 2026, the Board of Aldermen passed it 13-0 on 11 September 2026, and the Mayor approved it on 17 September 2026, the effective date the City records. This record rests on the City's official ordinance and board bill pages; the ordinance text itself was not opened, so its specific standards are not described.

What this does not establish

  • The ordinance and bill text PDFs on stlouis-mo.gov are excluded by the site's robots.txt (Disallow /*.pdf$) for automated retrieval and were not opened. The record relies on the City's official ordinance page and board bill page (summary, legislative history and effective date), so no definition, threshold, district or standard in Section 26.77 is stated here.
  • The stored adoption day is the Mayor's approval day; the Board passed the bill on third reading on 11 September 2026.
  • Ordinance 72182 (tax incentive prohibition) was passed the same day and is a separate record.

Unresolved questions

  • Which districts permit data centers and what standards Section 26.77 imposes.

Relationships

Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
