Initial analysis

The Young Family Trust-owned duplex at 405-407 Crestmont Drive in Forest Knolls, built in 1978, has undergone several significant improvements over the past two decades, with the most recent major renovation occurring in 2016. This 2-story multi-family residential building has seen substantial modernization efforts, including a comprehensive kitchen remodel in 2016 that involved removing the wall between the kitchen and dining room, installing a gas fireplace, relocating the washer/dryer, and replacing the hot water tank with a tankless system. Earlier improvements include an office expansion and bathroom/laundry room remodeling in 2010 (completed), and substantial exterior upgrades in 2007, including new siding installation, window replacements, and reroofing work. The building has maintained good systems updates, as evidenced by the comprehensive electrical and plumbing work completed during renovations, which included adding new circuits, lighting, and dedicated systems for modern amenities. While there have been a few municipal service calls regarding the property between 2017-2024, these were primarily related to external issues (such as sidewalks and trees) rather than building-specific concerns, suggesting generally good property maintenance and minimal resident-facing problems. The most recent building-related work was a sign repair in January 2024, indicating ongoing attention to property details.

Risk rating

How 405-407 Crestmont Dr's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
70th percentile

Out of 50 buildings in this neighborhood, 15 are predicted to be safer.
