1735-1737 Lyon St, San Francisco, CA 94115

1735-1737 Lyon Street is a three-story, multi-family residential building located in Lower Pacific Heights, consisting of two units and built in 1902. The property underwent substantial renovations between 2014-2015, including a $970,000 project to relocate one unit from the second to first floor, combine second and third floors into a single unit, add roof deck, and perform comprehensive remodels of kitchens, bathrooms, and bedrooms.

This renovation period generated several construction-related complaints from neighbors in 2015 regarding issues such as stability concerns, debris management, and potential unauthorized construction work, though all these complaints were marked as not active. During the same renovation period, the building received significant infrastructure upgrades including new fire safety systems (sprinkler installation), complete rewiring of both units, new plumbing systems for comprehensive bathroom and kitchen facilities, and the installation of new gas furnaces. More recent improvements to the property include the addition of a 4.08 kW solar PV system with battery storage in 2020-2021, and the installation of a hot tub in September 2020.

The building's maintenance history shows attention to basic infrastructure needs, including a complete reroofing project in 2014. Notably, a 2022 complaint was filed regarding a possible illegal unit merger involving an open stairway and replacement of a second kitchen with a wet bar, though this complaint appears to have been abated. The property's permit history demonstrates a pattern of significant upgrades and modernization efforts, particularly focusing on safety improvements and eco-friendly enhancements in recent years.
