Stand Alone Carriage Home Apartments

This version of an ADU carriage home shows how you can build a stand-alone garage apartment next to an existing structure, or on its own lot. For instance, if you own a large lot, you could build this multi-level living ADU for use as a rental property. Or you may want to make use of vacation property by starting with a SIP ADU and build a full structure at a later date.
