Initial analysis

The 6-unit, 3-story multi-family residential building at 630-636 Guerrero Street, owned by Golden Properties LLC, has undergone several significant structural and safety improvements since its construction in 1900. Most notably, the building completed a mandatory soft-story retrofit in 2018 at a cost of $72,000, bringing it into compliance with San Francisco's seismic safety requirements as a Tier 4 building. The property has a documented history of stair-related safety issues, with multiple repairs conducted between 2002 and 2006, including a complete soft-story retrofit in 2018 and kitchen/bathroom remodels in 2018. The building has experienced recurring safety concerns in the past, particularly in 2002-2006, when it faced multiple housing code violations related to fire safety, structural integrity, and maintenance issues, including problems with stairs, fire extinguishers, and egress obstructions. These violations were all marked as abated by May 2003.

More recent complaints indicate some ongoing maintenance issues, including a 2019 complaint about a non-functional doorbell and a 2018 report of unsafe working conditions during construction. The building's maintenance history shows attention to major safety concerns, particularly the completion of the soft-story retrofit and various stair repairs. Recent activity around the property, as evidenced by 311 calls, primarily relates to external issues such as parking enforcement and sidewalk maintenance, with the most recent concern being a sidewalk defect reported in November 2024. The building's historical complaints from the 1990s, including those related to fire safety and heating issues, suggest that the property has undergone significant improvements over the years, particularly in its response to safety-related matters, though some ongoing maintenance issues continue to be reported.

Risk rating

How 630-636 Guerrero 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
32th percentile

Out of 799 buildings in this neighborhood, 543 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 28.3%
Moderate concern 57.4%
Severe concern 14.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
