1220-1222 Green St, San Francisco, CA 94109

The two-unit residential building at 1220-1222 Green Street in San Francisco's Russian Hill neighborhood is a two-story flats and duplex structure built in 1906 and currently owned by the Green Street Irrevocable Trust. The property's most significant recent improvement was completed in 2017, involving a substantial window replacement project valued at $11,743, which included the installation of egress-compliant casement windows in bedrooms and four like-for-like Fibrex windows, with enhanced energy efficiency (U-factor < 0.32) and paintable finishes, while ensuring that none of the replacements were street-visible.

An earlier roofing work permit from 1994 is on record, though it appears to have expired without completion verification. The building's maintenance and incident history shows relatively few issues over recent years, with only three 311 service calls documented since 2018.

These incidents include a general cleaning complaint regarding loose garbage in October 2018 (which was resolved), a parking enforcement request for an Audi Q5 blocking a driveway in April 2021 (which could not be verified by responding officers), and an "other" category complaint in September 2021 that was ultimately directed to PG&E. The relative lack of reported issues and the significant recent window upgrade suggest regular maintenance attention, though the expired roofing permit from 1994 warrants note as an age-related infrastructure concern, albeit one that may no longer be relevant if subsequent work was completed under a different permit or requirement.
