Chino and Rancho Cucamonga have similar restriction levels.
Chino, CA
San Bernardino County
Federal law (49 U.S.C. §§40103, 41713 and FAA regulations) preempts the City of Chino from regulating aircraft-in-flight noise. Operations at Chino Airport (KCNO) — a San Bernardino County-owned general aviation reliever airport along Merrill Avenue at the southern edge of the city — are governed by the FAA and the airport sponsor, not Chino Municipal Code §9.40. What Chino does regulate is the land-use side: under the Chino Airport Comprehensive Land Use Plan (ACLUP) administered through San Bernardino County's 'Alternative Process' (no formal ALUC; local jurisdictions handle compatibility planning), the City must notice development applications within adopted airport noise and safety zones and assure compatibility with Chino Airport operations. The CMC §9.40.040 exterior noise standards (65 dBA daytime / 55 dBA nighttime in residential zones) expressly do not apply to aircraft operations.

Chino FAQ
Why can't Chino just limit small-plane noise overhead?
Federal law gives the FAA exclusive authority over aircraft in flight (49 U.S.C. §§40103, 41713). Cities can regulate land use under and around airports but cannot impose noise limits on flying aircraft. Chino CMC §9.40 explicitly exempts aircraft operations from its exterior noise standards.
I'm buying a house near Chino Airport — what should I know?
If the property is within the ACLUP airport influence area (especially under the 65 dB CNEL contour or in a safety zone), state law requires the seller to disclose the airport proximity, and many subdivisions carry recorded avigation easements. Verify ACLUP zone via San Bernardino County Land Use Services and check the recorded grant deed for easements.
Rancho Cucamonga FAQ
Can the city stop cargo jets from flying at night?
No. Aircraft operations are regulated by the FAA under federal preemption. The city cannot enforce local noise rules against planes in flight.
How do I report airport noise?
