658-664 Greenwich St, San Francisco, CA 94133

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 A Verizon wireless facility installation was proposed for a nearby SFPUC-owned light pole but was ultimately withdrawn.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.
