AI summary

The property at 643-645 Greenwich Street is a four-story multi-family residential building constructed in 1907, currently owned by WW-DY LLC. The building has undergone significant renovations over the years, with major work completed in 2002-2003 including the addition of two stories, garage modifications, and a comprehensive electrical upgrade featuring new lighting, switches, receptacles, and safety systems. A notable roof deck expansion was completed in 2019, increasing its size from 142 to 415 square feet. The building's safety systems were upgraded in 2005 with the installation of an overhead and underground N.F.P.A. 13 fire sprinkler system.

Recent activity at the property has shown some concerns regarding resident experience, particularly in 2024, with multiple noise complaints (including excessive noise and amplified sound electronics) and several reports of blocked driveways, though officers were often unable to locate the offending vehicles. There have also been instances of street cleaning issues and an encampment matter reported in 2024. The building's maintenance history includes termite repair in 2000 and various improvements to living spaces, including kitchen remodeling in 2000 and recent modifications to windows in 2021. Open permits in 2024 related to noise and parking issues suggest ongoing neighborhood interaction challenges.

Risk rating

How 643-645 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
81th percentile

Out of 362 buildings in this neighborhood, 69 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 floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 84.3%
Moderate concern 12.1%
Severe concern 3.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
