Martinez FAQ
Does CCC have a dark-sky ordinance?
Not a single comprehensive one, but Title 8 zoning and CEQA review impose shielding and directional requirements for most non-residential projects, particularly in rural and open-space-adjacent areas.
My neighbor's floodlight shines into my bedroom. What can I do?
Document the impact and contact CCC Code Enforcement. Unshielded lighting creating a nuisance can be cited under zoning code. Many disputes resolve after a courtesy letter from the County.
Oakley FAQ
Can I have a bright floodlight in my backyard?
It must be shielded so the bulb is not visible from neighbor's yards and not spill significant light onto adjacent properties. Motion-activated security lights are favored over constant-on.
Are holiday lights allowed?
Yes. Seasonal decorative lighting is generally exempt between specified dates (typically Nov 1 – Jan 15) from intensity and cutoff requirements.
What about solar garden lights?
Low-intensity solar path lighting is generally exempt from the shielding requirements because of their low lumen output.
