Initial analysis

The two-story, five-unit apartment building at 180 Blake Street in the Lone Mountain neighborhood, owned by Jang 2004 Trust, was constructed in 1975 and has undergone several significant modifications throughout its history. Most notably, the building completed a seismic retrofit in 2017 at a cost of $36,000, bringing it into compliance with current safety standards (Tier 3 soft-story status: Work Complete, CFC Issued). The building's permit history shows various other improvements, including a reroofing project in 2009 ($13,500), the creation of a stairway in 1989, and efforts to legalize unit configurations in the mid-1980s, though some permits from that era expired or were cancelled.

The property has undergone two routine housing inspections (1999 and 2004), both of which were resolved promptly. While there have been numerous 311 complaints in the vicinity since 2022, most have been related to street conditions, parking issues, or general urban maintenance rather than building-specific concerns. The most recent building-related permits and inspections suggest that major structural and safety systems have been properly maintained, with no significant building-specific complaints or violations on record in recent years. The property appears to be in good standing with respect to major safety and maintenance requirements, with all recent permits having been properly completed and closed.

Risk rating

How 180 Blake 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
43th percentile

Out of 519 buildings in this neighborhood, 296 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.

Number of units

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

Building size

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

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 65.9%
Moderate concern 18.8%
Severe concern 15.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
