Not who you're replying to, but I would imagine its an issue of registry and/or zoning depending on the type of business (and maybe tax stuff too). I'm from Australia so probably pretty different laws, but here at least you have to register the businesses address of operations and a part of that process is identifying your 'primary operation or activity', ie what the business does, some operations will be excluded from being conducted in residentially zoned areas regardless (large scale manufacturing, waste disposal & recycling, etc) but most trades will be permitted, I know a number of car mechanics that operate largely from home.
