Baywood Owners Improvement Association

 We are hosting a Baywood Owners Improvement Association (BOIA) membership drive and we need your help!  Spread the word to your Baywood neighbors to join BOIA by Monday, January 4, 2021. Then both of you will have a chance to win a $100 gift card to the San Mateo merchant, restaurant or establishment of your choice.  Support San Mateo small businesses and our Baywood community when it matters most!

If you already are a BOIA member, thank you! Please invite your neighbors to join.  If you aren't a member yet, please join and ask a neighbor to do so as well.  You will receive the twice-yearly paper BOIA newsletter and monthly Baywood Bulletin updates, as well as early access to BOIA events (the annual BOIA Yard Sale, Baywood Social (aka Ice Cream Social), BOIA Annual Meeting, Baywood Home Improvement and Holiday Lights Awards and other fun events). BOIA also keeps track of things that impact our neighborhood such as traffic islands, area parks, short-term rental regulations and street conditions. The Baywood Bulletin is a great way to know what is happening in Baywood.

To sign up as a BOIA member or nominate someone who you think would be a great fit in the BOIA community, please email us at

BOIA annual membership dues are: Gold Level - $135, Silver Level - $85, and Basic Level - $35.  The funds help us put on our events and help Baywood organizations and schools.  We currently support Baywood Elementary School, Borel Middle School, Aragon High School and the San Mateo Public Library.  The more BOIA members we have, the more we can support our schools and Library in these difficult times.


We are the Baywood Owners Improvement Association (BOIA).  We are proud to support the homeowners of our lovely Baywood neighborhood in San Mateo, CA. We have redesigned our website to better share what is going on in Baywood and make our community stronger. You can also check us out on Facebook or

Nextdoor Baywood. 

We welcome and encourage you to become involved through our many events and projects, or by submitting stories and information for us to share with the rest of the community. 


Please feel free to contact us at  We encourage everyone in Baywood to get involved in BOIA!
