Question:
“Hi Gary. I want to sell my home, but I’m afraid that my neighbor is dragging down my home value because he runs some kind of appliance repair shop out of his garage. He always has several washers and dryers in his driveway. Is all that even legal?”
Answer:
These are the zoning rules for home occupations in San Diego:
http://www.sandiego.gov/nccd/zoning/home.shtml
You should read it closely and perhaps talk with the city. Keeping the items in his driveway appears to be in violation of part of it that says:
Materials or products associated with the home occupation on the premises must be stored within an enclosed structure.
And perhaps:
The operation of the home occupation shall be consistent with permitted residential uses, shall not create any conditions that amount to a public nuisance, and shall not be detrimental to the residential neighborhood by causing increased noise, traffic, lighting, odor, or by violating any applicable ordinances or laws.
Hope that helps!
