Who This Plan Is For

Property owners who want rental income or extra living space without giving up their garage. The one-bedroom, one-bath studio has its own separate entrance, so it works as a long-term rental, short-term rental, guest suite, or home office. The two garage bays keep standard-sized vehicles, tools, and storage under cover. Check your local zoning for ADU regulations before purchasing.
