1723-1725 Lyon St, San Francisco, CA 94115

The three-story, two-unit multi-family residential building at 1723-1725 Lyon Street in Lower Pacific Heights, built in 1902, has undergone several significant improvements over the past decade to enhance safety and maintenance. Most notably, in 2017, a voluntary seismic upgrade was completed at a cost of $54,000 to address soft-story concerns, following earlier permitted attempts in 2017.

The building received a new roof in 2017 ($25,000) and has seen various modernization efforts including a gas fireplace installation (2002) and bathroom/kitchen remodeling (2002). The property's maintenance record shows attention to essential infrastructure, with the most recent work including a sewer lateral replacement in August 2023. The building's history includes several routine safety inspections by Housing Inspection Services in 2004 and 2017, with no active violations noted.

However, there have been multiple sewer-related issues, particularly in 2021 when several 311 calls were made regarding sewer odors and backups from the side sewer vent. The most recent plumbing work suggests ongoing efforts to address these historical challenges. The property has maintained its basic residential functionality, with recent complaints primarily related to exterior and street-level issues such as illegal postings and sidewalk parking, which are more reflective of neighborhood conditions than building-specific problems.
