UU San Mateo is at 300 E. Santa Inez Avenue, at the corner of N. Ellsworth Avenue, in San Mateo.


We reside within the North Central neighborhood of San Mateo. Being in a residential area means we do not have a parking lot, and street parking can be challenging. Please allow a few extra minutes to find a parking space on the street.

On Sundays, we have permission to use the parking lot of a nearby professional building. That parking lot is located about one-half block west of our main building, on E. Santa Inez near N. San Mateo Drive.

If you have mobility issues, note that we reserve a few handicapped parking spots near the front of our main building, and also in the driveway of our new property at the corner of E. Santa Inez and Ramona. If you require assistance, please drive up to the 300 E. Santa Inez entrance, and our hospitality team will park your car for you.

There is also a bike rack in front of our Religious Exploration building, and of course we encourage carpooling and public transportation.
