it's not that weird for a small business to be based out of a person's house (maybe it's just a construction thing tho). the last company i worked at in mhk was based in the owners house for like 20 years before they expanded too much and had to build an office. my current company was worked out of the owners garage and barn for 5-10 years before he got large enough for a big production building, then he started another business in his garage after that on the side and it's grown into another pretty successful business.
