Initial analysis

The two-story multi-family residential building at 317 Castro Street, constructed in 1905, is currently operated by Family Link and consists of two units. The property has undergone several significant renovations over the years, with the most recent completed project being a $12,000 reroofing job in May 2023. Historical improvements include bathroom updates in 1995 (replacement of tubs with stall showers and addition of toilets), a kitchen modification and full bathroom addition in 1994, and concrete slab work at the basement rear room in the same year. The building was previously converted into a group housing facility in 1994, specifically to accommodate families of persons with AIDS, under the management of Family Link.

The property has experienced various maintenance and environmental challenges in recent years, including a missing side sewer vent cover in July 2023 and a lifted sidewalk issue in December 2021, both of which were resolved. The location has been subject to multiple external cleanliness concerns, with several reports of general cleaning needs, garbage, and a graffiti incident in 2021. Street-related issues have included a parking violation report in October 2023, though the responding officer was unable to locate the offending vehicle. While there have been occasional reports of encampments in the vicinity (most recently in November 2024), these cases were either determined to be invalid or not directly related to the property's immediate surroundings. The building's maintenance history shows regular upkeep of critical systems, though the age of the structure and the nature of its conversion to a group housing facility suggest ongoing monitoring of both building systems and surrounding conditions is necessary.

Risk rating

How 317 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
86th percentile

Out of 287 buildings in this neighborhood, 40 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.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 81.2%
Moderate concern 11.2%
Severe concern 7.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
