In some communities it may be possible to obtain a permit to build an accessory dwelling unit (ADU) or granny flat on your property even if you do not own the house or duplex that you live in. The process can take time and money but is worth exploring if there is land available on your property that could accommodate a separate home for someone else (elderly parent or relative).
The first step is to determine whether there is enough space available on your property to build an ADU without significantly altering the existing structure. If so then get started with the permit process.
