450-452 31st Ave, San Francisco, CA 94121

The three-unit multi-family residential building at 450-452 31st Avenue in the Central Richmond neighborhood, owned by Mastrokyriakos Nikolaos, has undergone several significant renovations and faced notable challenges over its history, dating back to 1900. The most recent improvements include substantial 2020 renovations amounting to over $30,000 for bathroom and kitchen remodeling, along with electrical upgrades that installed additional outlets and lighting throughout the unit, a new 70-amp sub panel, and furnace replacement.

These improvements followed a concerning period in 2019 when the building experienced serious maintenance issues, including water damage affecting multiple rooms with electrical concerns, damaged ceilings, and mold problems—issues that were officially documented and subsequently abated by December 2023. Earlier renovations from 2007-2008 involved bathroom and kitchen remodeling, exterior repairs, and infrastructure improvements including new water lines and gas lines. The building's history shows a pattern of regular maintenance and upgrading, with significant work completed in the late 1980s to bring the building up to code (costing $10,000), multiple bathroom and kitchen renovations, and various infrastructure improvements.

Several plumbing, electrical, and building permits demonstrate ongoing investment in the property's modernization and maintenance, though there have been some instances of expired permits in the past. A historical complaint from 1995 regarding a possible illegal dwelling unit in the basement of a rear yard cottage was resolved within one month. The building has also experienced occasional exterior and parking-related issues, as documented in recent 311 calls, though these are typically routine urban living challenges rather than building-specific problems.
