Initial analysis

The 315-317 Crestmont Drive property is a three-story, two-unit multi-family residential building located in the Forest Knolls neighborhood, built in 1964 and currently owned by Shirley Suwen Ng. The building has undergone several maintenance and improvement projects over the years, with the most recent being a garage door replacement in late 2022. Historical records show earlier repairs including bathroom renovation in 1997 and dry rot damage repairs to the stairway in the same year. The property has experienced multiple tree-related issues in recent months, with numerous 311 calls between December 2024 and January 2025 reporting problems with damaged and overgrown trees.

While the building itself has not had reported fire incidents directly at this address, there is a history of fire safety violations associated with a nearby address (500 Clarendon Ave) from 2019 and 2023, including issues with sprinkler systems, exits, and fire extinguishers, though these have been marked as abated or rescinded. The property has not been subject to any recent tenant buyouts, with the most recent recorded buyout occurring in August 2017 for a single tenant at an adjacent address (307 Crestmont Drive). Recent activity around the property has primarily involved municipal service requests, including parking enforcement and tree maintenance, rather than building-specific issues. The garage area was previously modified with the installation of steel posts and bollards in 2007, suggesting ongoing attention to security and maintenance needs.

Risk rating

How 315-317 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
88th percentile

Out of 50 buildings in this neighborhood, 6 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 85.0%
Moderate concern 11.4%
Severe concern 3.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
