Coastal Development: Hesperia vs Rialto
How do coastal development rules compare between Hesperia, CA and Rialto, CA?
Hesperia and Rialto have similar restriction levels.
Hesperia, CA
San Bernardino County
Hesperia is an inland city in the High Desert of San Bernardino County, located approximately 85 miles inland from the Pacific coast at an elevation of roughly 3,200 feet. The California Coastal Act of 1976 (Cal. Public Resources Code §30000 et seq.) applies only within the defined coastal zone — Hesperia is far outside that zone, so no Coastal Development Permit (CDP) or Local Coastal Program (LCP) review applies. There is no local coastal-development ordinance because the city is not coastal. State coastal statutes are listed below for completeness.

Hesperia FAQ
Do I need a Coastal Development Permit in Hesperia?
No. The California Coastal Act (Cal. Public Resources Code §30000 et seq.) only applies within the mapped coastal zone, which extends inland from the Pacific Ocean. Hesperia is roughly 85 miles inland in the Mojave Desert, entirely outside the coastal zone. Local development is governed by HMC Title 16 (Development Code) and CEQA where applicable.
Who handles environmental review for new development?
Discretionary development projects undergo California Environmental Quality Act (CEQA) review under Cal. Public Resources Code §21000 et seq., administered by the City of Hesperia as lead agency for most local projects. Federal review (NEPA) attaches where federal funding or permits are involved.
Rialto FAQ
Do I need a Coastal Development Permit to build in Rialto?
No. The California Coastal Act and the Coastal Commission's permit jurisdiction apply only inside the Coastal Zone defined in PRC §30103. Rialto is roughly 60 miles inland and is entirely outside the Coastal Zone, so no CDP is ever required.
What replaces coastal review for Rialto projects?
Environmental review falls under CEQA (PRC §21000 et seq.) implemented by the city as lead agency, plus Rialto's grading, floodplain, stormwater, and zoning codes (Titles 13, 15, and 18).
Does the Coastal Commission have any authority over Rialto?
No. The Commission's jurisdiction is geographically limited to the Coastal Zone. Inland cities like Rialto are not subject to Coastal Act permitting or LCP requirements.
