2729-2731 Union St, San Francisco, CA 94123

The two-unit, two-story multi-family residential building at 2729-2731 Union Street in Cow Hollow, owned by Jonathan C. Herpel, was constructed in 1923 and has undergone significant renovations, most notably in 2015 when a substantial $647,300 addition was made to the rear of the building, including a new roof deck on the second floor and the installation of a full automatic sprinkler system.

The building's maintenance history shows earlier attention to basic upkeep, such as reroofing work completed in 2001 for $5,700. Recent records from 2023 to 2025 indicate persistent parking enforcement issues in the vicinity, with multiple citations issued for driveway blocking, though some officers have been unable to locate offenders. The property has experienced several infrastructure challenges in the past year, including incidents of flooding and water main issues in October 2024, though these were determined to be outside the building's scope.

The street area around the building has faced various maintenance challenges, including debris, waste, and color curb complaints, all of which have been resolved through proper channels. It is worth noting that there has been one recorded cooking-related fire incident, though it was confined to a container and resulted in no civilian injuries. The most recent building permit activity indicates the property is up to date with current safety and modernization requirements, particularly with regard to fire safety systems.
