1657 Hayes St, San Francisco, CA 94117

The three-story, multi-family residential building at 1657 Hayes Street, built in 1900, consists of two units and is classified as a Flats & Duplex structure in the Park North neighborhood. The building's most significant recent work occurred in 2014, when a $30,000 interior renovation of the lower floor unit was permitted, involving non-structural wall removal and updates to plumbing fixtures and appliances. However, the property experienced a notable cluster of violations in 2004 that collectively raised serious resident safety and comfort concerns.

These violations, which were resolved by February 2005, included issues with the electrical system, central alarm system, heating system (failure to maintain minimum room temperatures), stairs and handrails, lighting, security measures, and smoke detection equipment. A 1997 complaint about inadequate bathroom water access was promptly addressed within two days. The building's recent history shows various external maintenance and neighborhood issues, including multiple reports of illegal postings (2021-2022), parking violations (notably blocking the driveway in 2021 and 2024), and a 2022 graffiti incident.

Recent 311 calls have primarily concerned external matters such as street cleaning, sidewalk parking violations, and a 2024 encampment issue nearby, rather than internal building conditions. While the 2004 violations indicate a past period of maintenance and safety concerns, the property has undergone some renovation since then, though historical permit activity shows several permits from 1990-2002 that were expired, including one for kitchen and bathroom water damage repairs from 1990, and a permit to enlarge an apartment unit from 1990. A single fire complaint from December 2008 was resolved on the same day it was filed, with conditions corrected.
