Build a luxury home for yourself and the second for resale! Preliminary plans for the proposed lot split and building design plans are available for to view. Per the seller, the anticipated lot line adjustment process could take approximately two to three months to complete. The new owner would be fully responsible for obtaining any/all applicable costs for submission, review, permit, building fees, reports and surveys.

10/10GreatSchools RatingParent Rating AverageRalston Middle School is the most racist educational institution that we’ve experienced. Many students spew hate speech and racial slurs but are never corrected. The administration - all the way up to the school board- is complicit. This school is emotionally, psychologically and physically unsafe for black and brown children. That’s such a shame. The city needs to investigate immediately.Parent Review1mo ago - Carlmont High School

10/10GreatSchools RatingParent Rating AverageI have recently had three kids graduate in 2024 and 2023.Some teachers are simply exceptional, while others are lacking strategies for teaching.So it can be a mixed bag depending on the teacher you get.The chemistry class was basically videos and minimal learning. The physics class my kids had was excellent. Same for the stats class, excellent. If your child plays an instrument, this is a great place for them to hone their skills. However, I was disappointed in English requirements for my kids.Two out of three of my kids went on to public colleges in California. The physics and stats they learned were excellent fundamentals for their college courses.Overall, I would give Carlmont 3.9 score out of 5.Parents need to be involved, it easy for kids to get lost in high school.Parent Review2mo ago
