Summary

In Monterey County's Coastal Zone, community information and directional signs are allowed only on property adjacent to freeways leading to or through cities and communities, capped at 400 square feet, barred from naming any specific business except a nonprofit, and require a discretionary Coastal Development Permit.

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

Full Breakdown

060, part of the Title 20 Coastal Zoning Ordinance governing signs in the unincorporated Coastal Zone, regulates off-site advertising signs there. Subsection (D)(1) creates a narrow category for 'community information and directional signs' that may be erected only on property adjacent to freeways approaching, passing through, or going near cities or communities. No single sign in this category may exceed 400 square feet, and the sign cannot identify any specific business, person, entity or organization; only a nonprofit organization qualifies for message content. 70, the county's most rigorous, hearing-based sign review track, rather than the lighter Coastal Administrative Permit used for smaller signs elsewhere in the chapter.

060(D)(3) requires that outdoor advertising and other off-site advertising signs generally be located in an industrial or commercial zoning district; freeway-facing community/directional signs are the narrow carve-out that can sit on property zoned for other uses as long as it fronts a freeway corridor. Because Title 20 applies only within the Coastal Zone, a freeway-facing sign proposed outside that zone, for example along Highway 101 in the Salinas Valley, falls instead under the parallel Title 21 Inland Zoning Ordinance sign chapter, not this section.

Violations & Fines

Erecting a freeway-facing community or directional sign without first obtaining the required Coastal Development Permit, exceeding the 400-square-foot cap, or displaying a for-profit business name on the sign violates §20.60.060(D)(1) and is enforced as unpermitted development under the Coastal Zoning Ordinance, subject to permit denial and removal by the Monterey County Planning Department.

Frequently Asked Questions

Can a business put up its own sign next to Highway 1 in the Coastal Zone?
No. Under §20.60.060(D)(1), a freeway-facing community information or directional sign cannot identify any specific business, person or organization; only a nonprofit organization's name may appear, and the sign is capped at 400 square feet.
What permit does a freeway-facing sign need?
It needs a Coastal Development Permit under Chapter 20.70, the county's discretionary, hearing-level review track, because §20.60.060(D) places community information and directional signs in the category of signs requiring a Coastal Development Permit rather than a simpler administrative permit.
Does this rule apply county-wide?
No. Section 20.60.060 sits in Title 20, the Coastal Zoning Ordinance, so it governs only the unincorporated Coastal Zone; freeway-facing signs elsewhere in unincorporated Monterey County are regulated under the separate Title 21 Inland Zoning Ordinance sign chapter.
