249-251 Lexington St, San Francisco, CA 94110

The two-unit residential building located at 249-251 Lexington Street in San Francisco's Inner Mission neighborhood is a two-story flats and duplex structure built in 1909, currently owned by Kenny L F Guan and Betty Zhou. The building's maintenance history shows several significant interventions, with the most recent major work being a reroofing project completed in 2016 at a cost of $6,700.

Earlier maintenance records include two street space permits issued in 2015 and 2009, and an important structural repair in 1987 when dry rot damage was addressed at the base of a wall and the front garage door jambs. The property has generated two 311 calls in recent years, both relating to general street cleaning issues involving loose garbage, with the most recent incident occurring in May 2021 and both cases being successfully resolved by the Department of Public Works.

The building's documented history indicates regular maintenance of major systems, such as the roof replacement in 2016, though it is worth noting that the dry rot repair from 1987, now over three decades old, represents the only recorded structural intervention. The recent street cleaning issues reported through 311 calls appear to be more related to neighborhood conditions rather than building-specific problems, and both cases were promptly addressed by city services. The property has maintained its original multi-family residential use designation throughout its history.
