Initial analysis

650 Alvarado Street is a 27-unit, 3-story multi-family residential building constructed in 1964, currently owned by Ralston Bridge Alvarado LLC. The building has undergone several significant safety system upgrades in recent years, including a comprehensive fire alarm system replacement in 2023 costing $66,979 to comply with fire code requirements, followed by a water flow system modification in July 2024 to remove monitoring for a non-existent sprinkler system. The building completed a mandatory seismic retrofit as a Tier 2 soft-story structure in 2016, demonstrating compliance with San Francisco's seismic safety requirements. However, there are concerning recent building issues, including a May 2024 complaint about water intrusion and suspected mold in unit 105, and a history of heating system problems, with multiple complaints about inadequate heat documented between 2003 and 2010.

The property has experienced recurring fire safety system issues over the years, with multiple fire alarm activations, extinguisher concerns, and fire code violations between 2006 and 2023. Historical violations from 2002 included various fire safety and building maintenance issues, including problems with handrails, fire escapes, and sprinkler systems, though these were all abated by January 2003. More recent building improvements include renovation work in 2013 for unit 105 (kitchen and bathroom remodel), and numerous electrical upgrades throughout the building. The building's maintenance history shows ongoing attention to building systems, though some recent complaints suggest potential maintenance challenges. Note that there was one tenant buyout recorded at this address in 2020, with compensation of $75,000 to one tenant at the adjacent property (672 Alvarado Street).

Risk rating

How 650 Alvarado 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
2th percentile

Out of 1879 buildings in this neighborhood, 1841 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 23.6%
Moderate concern 36.7%
Severe concern 39.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
