Initial analysis

The 9-unit multi-family residential building at 608-612 Hemlock St in Lower Pacific Heights is a two-story flats structure built in 1904 and currently owned by Seiki Justin S. The building has undergone mandatory soft-story seismic retrofitting as a Tier 3 property, with work completed and a Certificate of Final Completion (CFC) issued, indicating compliance with San Francisco's seismic safety requirements. The building's maintenance history shows regular fire safety compliance, with a fire extinguisher recharge violation recorded and promptly abated in February 2000. Between 2011 and 2016, there were several routine safety inspections conducted by Housing Inspection Services, including one complaint about a non-functioning toilet in March 2016, though all issues appear to have been resolved appropriately.

The most significant recent building-specific events occurred in 2016, when multiple street space permits were issued between May and October, each with a nominal cost of $1. More recently, between December 2024 and January 2025, there has been notable activity in the immediate vicinity of the building, including multiple reports of garbage and debris requiring street and sidewalk cleaning, with some incidents involving hazardous materials like glass and human waste. There were also two reports of transit shelter platform damage in December 2024. The building experienced two notable fire-related incidents: a malfunctioning alarm system and a natural gas leak, neither resulting in civilian injuries. The property's immediate area has seen recurring issues with encampments and urban debris, as evidenced by multiple 311 calls for cleanup and maintenance services between December 2024 and January 2025, though these external conditions do not directly reflect on the building's internal maintenance record.

Risk rating

How 608-612 Hemlock 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
21th percentile

Out of 670 buildings in this neighborhood, 529 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 52.7%
Moderate concern 23.9%
Severe concern 23.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
