Summary

In the county's C1-MU and C2-MU mixed-use zones, a new or altered outdoor dining area can't open until Imperial County's planning department grants design review approval under the mixed-use flexibility standards.

These county ordinances apply to unincorporated areas of Imperial County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

No new building, structure, outdoor dining area or sign exterior alteration or enlargement of an existing building, structure, outdoor dining area or sign shall be commenced in any mixed-use zone until design review approval has been granted pursuant to Division 3 (site and design standards).

Full Breakdown

Imperial County's mixed-use flexibility chapter requires design review approval before any new building, structure, outdoor dining area, or sign is built, altered, or enlarged in the C1-MU (mixed-use light commercial) or C2-MU (mixed-use general commercial) zones. The rule sits inside the county's broader mixed-use standards, which push commercial and residential development to integrate rather than stand alone. Outside these two zones, including most unincorporated commercial areas, this specific design-review trigger for outdoor dining does not apply, though a site plan review permit may still be required for other new development.

Violations & Fines

Building or altering an outdoor dining area in a mixed-use zone without design review approval violates Title 9; the county's land use enforcement officers may issue citations and pursue abatement under Division 13.

Frequently Asked Questions

Does this apply to a restaurant patio in downtown El Centro?
No. El Centro is an incorporated city with its own code. This county rule governs only the unincorporated mixed-use (C1-MU/C2-MU) zones.
What if my outdoor dining area is outside a mixed-use zone?
This specific design-review trigger doesn't apply, but other Title 9 site plan or use-permit rules for the applicable zone may still govern.
