2 rules for unincorporated Mariposa County, California.
Verified from official government sources
Mariposa County's current zoning code (Title 17, Ch. 17.108) contains no general dark-sky/outdoor-lighting ordinance. A proposed Development Code update (draft Sept 2024) would add Section 17.46 'Outdoor Light and Glare,' requiring full-cutoff, fully shielded fixtures that do not direct light into the sky or onto adjacent properties. This draft is not yet adopted.
The adopted Mariposa County code has no specific light-trespass standard for homes. A proposed Development Code update (draft Sept 2024, Section 17.46) would require shielded fixtures that 'shall not direct light into the sky, adjacent properties, public easements, or rights-of-way.' Until adopted, light spilling onto a neighbor is addressed mainly as a nuisance.
