671 38th Ave, San Francisco, CA 94121

The two-unit residential building at 671 38th Avenue, located in San Francisco's Outer Richmond neighborhood, has undergone several significant modifications since its construction in 1924. The property has a documented history of expansion and alteration, including a completed vertical addition in 1990 and a horizontal extension adding two bedrooms at the rear in 1985.

Most concerning is an active building violation issued in April 2024, following a complaint in March 2024, regarding unauthorized modifications including a concrete block wall in the rear yard, enclosure of a lightwell with skylights, and the installation of a wet bar under the rear deck, among other changes. These unauthorized modifications prompted the issuance of a building permit in September 2024, valued at $15,000, to remove the concrete block wall, restore the lightwell, and remove the wet bar, among other compliance requirements.

The property has generated multiple 311 calls and complaints in recent years, including numerous reports of parking violations related to blocked driveways between late 2023 and 2024, as well as noise complaints during construction work in March 2024. A garbage and debris complaint was resolved in January 2025, and there was one fire complaint in January 2021 that was promptly corrected. The building's recent history suggests ongoing construction activity and multiple compliance issues, particularly regarding parking management in the vicinity, as evidenced by the ten parking-related complaints within a one-year period.
