How we identify these homes

ADU, guest house or casita as described in MLS data; permits, legal status and rental use are not verified. Buyer to verify with the city.
Questions buyers ask
Is the ADU permitted?
The MLS does not verify permits. Ask the listing agent for permit records and confirm with the city building department before relying on rental income.
What is ADU potential?
Listings whose remarks describe room, plans or zoning for a future unit; nothing has been built or approved.
Can Duri help evaluate an ADU?
Yes; she works with MAD Realty Co. on renovation and ADU projects and can walk the lot with you.
