19-21 Jansen St, San Francisco, CA 94133

The property at 19-21 Jansen Street is a three-story multi-family residential building constructed in 1908 in San Francisco's Russian Hill neighborhood, currently owned by the Lockard/Marduel Revocable Trust and containing two units. The building underwent significant renovations in 2005, including a $40,000 conversion of the ground floor into living space for the lower unit, kitchen and bathroom remodeling with window additions, and electrical system upgrades including sub-panel installations, all of which were completed successfully.

More recent improvements include a bathroom renovation and bedroom upgrades in late 2022, valued at $15,000. The building experienced some notable maintenance issues in 2004-2005, particularly related to plumbing, with multiple violations recorded for defective and leaking building drains and sewer systems, though these were resolved by February 2005. A water leak affecting the neighboring property was reported and addressed in March 2005.

The property has maintained its infrastructure reasonably well since then, with a reroofing project completed in 2004. Recent external issues recorded through 311 calls primarily relate to street and parking matters, including a 2022 manhole cover issue and several parking-related incidents, none of which directly impacted the building's habitability or safety. The most recent building permit activity in 2022 suggests ongoing maintenance and updating of the property's interior spaces.
