How we identify these homes

The MLS interior-features field reports an in-law floor plan or multiple primary suites, the other-structures field reports a guest house, or the remarks describe a separate suite, casita or next-gen layout. Layouts are as described by the listing agent; verify separate entrances, kitchens and permits in person.

Questions buyers ask

What is a next-gen home?

A builder floor plan with a private suite that has its own entrance, living area and often a kitchenette, common in Ontario Ranch.

How is this different from the ADU page?

ADU homes have a separate dwelling unit; this page also includes attached suites and dual primary bedrooms.

Can Duri find off-market options?

Yes; ask about her buyer-network search for specific layouts.
