AI summary

The property at 658-664 Greenwich Street is a two-story, six-unit multi-family residential building constructed in 1907 and currently owned by the John A Ertola By-pass Trust. The building has undergone several roofing projects over the years, with the most recent reroofing completed in 2007 at a cost of $5,900, following earlier projects in 1994 and 1985. A significant violation was filed in November 2018 regarding unpermitted construction of a balcony and stair egress at the rear of the building, which remains active with multiple Notices of Violation issued between January and April 2019, including a final warning letter. This violation notably follows a permitted rear deck rebuilding project completed in 1999, suggesting potential issues with maintaining proper permitting processes for exterior modifications.

The property has undergone routine housing inspections between 1997 and 2010, all of which were completed without noted violations. More recent issues in the area include multiple parking enforcement calls in 2021 for sidewalk parking and driveway blocking, as well as an open case from July 2021 regarding tree root damage to sidewalks. A Verizon wireless facility installation was proposed for a nearby SFPUC-owned light pole but was ultimately withdrawn. The building's maintenance history shows regular upkeep, though the active violation regarding unpermitted construction raises some concerns about recent permitting compliance.

Risk rating

How 658-664 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.
