Initial analysis

The property at 620-622 Castro Street is a two-unit, two-story multi-family residential building constructed in 1905, currently owned by Kay E Hefferlin and located in the Eureka Valley/Dolores Heights neighborhood. The building has undergone several significant infrastructure improvements recently, including the replacement of two water heaters (40 to 66 gallon conversion) in November 2023, with corresponding electrical work completed in March 2024. A substantial re-roofing project is currently in progress, with a $20,000 permit issued in April 2024, following an earlier cancelled roofing permit from February 2024 that was valued at $26,000.

The building has a documented history of maintenance and improvements, including electrical upgrades (2003), previous roofing work (1989), and concerning historical repairs such as fungus damage remediation in 1997. Recent environmental concerns have emerged, with multiple urban maintenance issues reported in 2024, including three encampment reports in September 2024, tree-related concerns (lifted sidewalk roots and overgrown trees) in May 2024, and a general cleaning request in May 2024. The property has experienced recurring parking enforcement issues, with several complaints about driveway blocking, though in most cases, officers were unable to locate the offending vehicles, except for one citation issued in July 2024. While the building's recent upgrades indicate active maintenance and improvements by the owner, the surrounding area has faced some urban maintenance challenges as evidenced by the recent 311 calls.

Risk rating

How 620-622 Castro 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
93th percentile

Out of 1278 buildings in this neighborhood, 89 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.

Building age

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

Neighborhood location

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

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 89.9%
Moderate concern 7.6%
Severe concern 2.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
