Redmond FAQ
My Redmond neighbor's floodlight shines in my bedroom — what now?
Ask them to shield or redirect it first, and if that fails you can file a nuisance complaint with Redmond Code Enforcement.
Can I install motion-sensor floodlights in my yard?
Yes, motion-sensor lighting is encouraged as long as it does not cause persistent glare or direct spill into a neighbor's windows.
Seattle FAQ
What can I do about a neighbor's security light shining into my bedroom?
Start by talking to your neighbor, as many are willing to adjust their lighting. If that fails, you can file a nuisance complaint under SMC 10.09 for unreasonable light trespass. For commercial or multifamily properties with non-compliant lighting, file a complaint with SDCI, which can enforce land use code lighting standards.
Are there specific light trespass standards in Seattle?
Seattle does not have specific foot-candle limits for light trespass at property lines like some jurisdictions. Instead, the land use code requires shielded, downward-directed lighting for new development, and the general nuisance ordinance addresses unreasonable light conditions that interfere with neighboring property use.
