4309-4311 23rd St, San Francisco, CA 94114

The property at 4309-4311 23rd Street is a two-unit, two-story multi-family residential building located in Noe Valley, constructed in 1947 and currently owned by the Wright Family Trust. The building has undergone several significant improvements over the years, with the most recent major work being comprehensive electrical upgrades in May 2018, including the installation of 50-amp sub-panels and complete rewiring of both units. Prior renovations include bathroom window replacements in 2005 (installing new vinyl or aluminum tempered windows), a complete re-roofing in 2000, and repair of a damaged stucco fence in 1999.

A horizontal addition was completed in 1991, expanding the building's footprint. The property's recent maintenance record shows regular upkeep, though there has been one notable incident involving the alarm system, which was triggered due to malfunction with no injuries reported. The surrounding area has experienced recurring issues with illegal parking, particularly between 2020 and 2024, with multiple enforcement cases including blocked driveways and sidewalk parking, though these are external to the building itself.

There was a recent case in February 2024 regarding a damaged tree, which is currently under review. The building's infrastructure appears to be well-maintained, with no recorded internal safety issues or building code violations in recent years. A pavement defect was reported in 2020 and transferred to PUC for assessment, and there was a general cleaning issue noted in 2020 involving loose garbage on the street.
