Can I have a second floor in my detached garage or barn?
No, unless there is an established (or soon to be established) agricultural use and the structure is a minimum of 100 feet from ANY property line, in which case you may construct a second floor. In such cases, the use of the second floor is limited to the storage of feed, hay, agricultural tools or equipment, an office for the agricultural business, or other items related to the agricultural use of the property. Uses not allowed include recreation rooms, dens, bedrooms, kitchens, and hobby or craft workspace. The number of plumbing fixture units is limited to 2. Fixture units include sinks, toilets, showers or tubs.
