Berkeley's Home Business: The Rules That Matter
Every city handles home business a little differently. In Berkeley, California, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Key details: Max size: 1 sq ft. Mounting: Flush to wall. Illumination: Prohibited. Freestanding: Not allowed. First fine: 100 dollars.
