Initial analysis

The 3-story, 9-unit multi-family residential building at 480-490 Greenwich Street in Telegraph Hill, operated by Rsa 0221 Irrevoc Tr, was constructed in 1924 and has undergone several significant improvements in recent years. Most notably, the building completed a mandatory Tier 3 soft story retrofit in 2017-2018, which involved the installation of additional shear walls and moment connections to improve seismic safety, at a total cost of approximately $57,500. The building has experienced some maintenance and safety issues in recent years, including three fire safety complaints in 2023-2024 related to electrical systems, extinguishers, and blocked exits, though all were marked as "Condition Corrected." A cluster of renovation work was completed in 2014 in Unit #3, including kitchen upgrades and plumbing modifications, though this work initially generated a building complaint regarding unauthorized construction.

The property has a history of routine housing inspections dating back to 1997, with no significant violations on record. Recent maintenance activities have included street space permits in 2011, reroofing work in 2008, and various historical improvements. The building's systems have been actively maintained, with a recent electrical infrastructure upgrade in 2024. The surrounding area has experienced typical urban issues as evidenced by recent 311 calls, though these are primarily related to street maintenance and parking concerns rather than building-specific problems. While there have been multiple maintenance issues reported through 311, including graffiti, tree maintenance, and parking violations, these are external to the building itself and have mostly been resolved through proper channels.

Risk rating

How 480-490 Greenwich 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

Out of 684 buildings in this neighborhood, 650 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 10.3%
Moderate concern 30.7%
Severe concern 59.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
