Initial analysis

The property at 350 Hermann Street in Hayes Valley is a three-story, two-unit multi-family residential building constructed in 1900, currently owned by Alan A. Heck. The building has undergone several significant improvements and maintenance work over the past few years, with particular attention paid to safety compliance in 2021. This includes the replacement of exterior metal guardrails with wood guardrails on the entry stairway (cost $10,000), repairs to wooden steps from the lower level to the garden (cost $4,000), and the installation of a fire-rated door from the garage to the hallway. These modifications were completed under physical inspection report CC-8440, which also led to electrical upgrades including a new meter installation and plumbing improvements with backwater devices and vacuum breakers. The building's electrical system was further enhanced in 2021, and a fire complaint from 2017 was resolved promptly within five days.

Historical records show that the building underwent substantial renovations in 1996, including the conversion of ground floor storage to off-street parking and living space, as well as remodeling of the kitchen and bathroom. Earlier maintenance work includes reroofing completed in 2006. The property has experienced several municipal service requests in recent years, primarily related to tree maintenance and sidewalk conditions, with multiple tree-related incidents reported in 2023 and 2024. Two significant tree-related issues were resolved in 2023, and there is currently an open sidewalk defect case from February 2023. The most recent municipal interaction was a Shared Spaces request in September 2024. While the building appears to be maintaining compliance with safety and maintenance requirements, the surrounding area has experienced periodic issues with tree damage, sidewalk conditions, and street cleaning needs, all of which have generally been addressed through standard municipal processes.

Risk rating

How 350 Hermann 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
92th percentile

Out of 1027 buildings in this neighborhood, 82 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location

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

12-Month severity forecast
No violation 87.9%
Moderate concern 8.2%
Severe concern 3.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
