Initial analysis

The property at 18-20 Chenery Street in Glen Park is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by the Tania M Shertock Revocable Trust. The building has undergone several significant renovation attempts over the past decade, most notably an effort to add an ADU (Accessory Dwelling Unit) in 2017-2018, which included comprehensive structural improvements, bathroom, bedroom, and kitchen installations, though this project was ultimately cancelled. During 2018, the property experienced flooding concerns that prompted the installation of drainage systems, including trench drains at the garage and front door, along with a sump pump installation at the rear, which are documented through both building and plumbing permits.

More recent improvements include a completed upgrade to a 200 amp electrical service in July 2019, though a related electrical permit for new unit wiring from October 2018 expired. The building experienced a sewage backup incident in April 2023, which was resolved, and there are ongoing concerns with a collapsed sidewalk noted in July 2023. Historical records show multiple parking enforcement issues in the vicinity between 2018-2020, including several instances of blocked driveways and sidewalk parking, though these are unrelated to building conditions. The property's infrastructure has received attention over the years, with various plumbing updates including sewer trap replacement in 2014 and bathroom remodels, indicating ongoing maintenance of essential systems.

Risk rating

How 18-20 Chenery St'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
98th percentile

Out of 364 buildings in this neighborhood, 7 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.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 90.4%
Moderate concern 7.0%
Severe concern 2.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
