Initial analysis

The 12-unit apartment building at 590 4th Avenue in the Inner Richmond was constructed in 1964 and has experienced several significant safety-related events over the years. Most recently, there was a boiler permit violation reported in November 2023 that was resolved by December 2023. The building has undergone multiple fire safety system upgrades since 2020, including several fire alarm replacements and modifications to low frequency sounders, with the most recent work completed in April 2022. A notable cluster of fire safety issues occurred between 2006 and 2021, including violations related to alarm systems, sprinkler systems, and fire escape maintenance, though records indicate most were promptly corrected.

The property has experienced recurring boiler permit issues, with violations noted in 2010, 2013, and most recently in 2023, suggesting ongoing challenges with maintaining proper documentation and compliance. Other maintenance history shows a bathroom remodel in Unit 201 (2015), garage door replacements (2010), and various routine safety inspections. The building has had minimal fire incidents, primarily consisting of alarm system activations and power-related occurrences, none resulting in civilian injuries. Recent 311 calls from 2024 primarily relate to street-level issues outside the building, such as sidewalk cleaning and parking concerns, rather than internal building problems.

Risk rating

How 590 4Th 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.

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 31.6%
Moderate concern 26.3%
Severe concern 42.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
