Initial analysis

The three-story, 10-unit multi-family residential building at 2550 Golden Gate Avenue, owned by Howard S & Pamela Erlanger, was constructed in 1960 and has undergone several significant safety and maintenance improvements over the years. Most notably, in 2024, the building received a major fire alarm system upgrade to meet current safety standards, including new low-frequency sounders in sleeping areas and updated devices throughout the building, with an associated cost of $41,732. The building has completed mandatory seismic retrofitting as a Tier 3 soft-story building, which was achieved along with obtaining a Certificate of Final Completion (CFC). Other major maintenance work has included reroofing projects in 2014 and 1995, removal of dry rot siding in 2011, and resolution of various building code compliance issues in 1985.

The building's history includes several fire safety-related complaints and violations, particularly in 2003 and 2011, regarding smoke detectors, emergency exits, and fire escape equipment, though all were subsequently corrected. A roofing work violation was noted in 2014, which was also addressed. The property has experienced routine maintenance issues typical of urban environments, including sidewalk defects, graffiti, and debris concerns, with the most recent incidents occurring in 2024. The building has had multiple fire alarm activations and system maintenance issues recorded between 2009 and 2024, though none resulted in actual fires or injuries. Recent 311 calls primarily relate to exterior maintenance concerns, though these were typically resolved promptly by city services.

Risk rating

How 2550 Golden Gate Ave'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
4th percentile

Out of 519 buildings in this neighborhood, 498 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.

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 30.7%
Moderate concern 36.6%
Severe concern 32.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
