Food service projects:
The Williamson County and Cities Health District (WCCHD) also must review plans for any projects involving food service (including restaurants, bars, food trucks, convenience stores, day care facilities, etc.). The food establishment permit application and food establishment plan review application forms are posted on the WCCHD website with instructions.
Permit review procedure:
After your application is received it will be distributed to all applicable review staff. The reviewers will email their comments directly to the primary contact identified on the application. Responses to the comments should be emailed back directly to the reviewer. Paper redlines may be picked up at the Inspections Services counter.
When all comments have been addressed the permit will be issued and staff will call the applicant to pick up the permit at the Inspections Services counter. Instructions for using the online Automated Inspection Request System will be included with the permit.
Review time varies depending on the complexity of the project and the completeness of the submittal. The average turnaround time from submittal to permit is currently 4-6 weeks for commercial projects or 1-2 days for residential projects.
If any re-inspection fees are assessed, they must be paid before scheduling the final inspection.
