Project planning resources
Houston’s infrastructure transition depends on the submission record.
Houston’s revised notice says public/private projects submitted for initial review on or after June 1, 2026 must meet the 2026 Infrastructure Design Manual requirements. This is a city infrastructure-review update.
For projects subject to Houston Public Works infrastructure review. This is not a blanket change to every building permit or a Harris County-wide rule.
Request a project reviewCheck the submission record before changing course
The revised City notice distinguishes new submissions from substantially complete plans submitted earlier.
Keep the completeness evidence
The notice retains 2023 requirements for substantially complete plans submitted for initial review before June 1, 2026. Confirm that your record meets those conditions.
Resolve the consequences of switching
The City describes cancellation and a new submission to elect the 2026 requirements for an earlier project, with new fees and no refunds. Ask the City and your design team before taking that step.

Is an older announcement enough to choose the edition?
No. Read the revised notice and confirm the actual project dates and conditions. A cached headline can omit a later transition clarification.
