4006-4008 21st St, San Francisco, CA 94114

The three-unit multi-family residential building at 4006-4008 21st Street, owned by Steven M. Bain, has undergone significant improvements and faced several maintenance challenges since its construction in 1932. The property has seen substantial renovations over recent years, with the most recent major work planned for 2024, including an interior remodel of apartment #3 to add a bedroom and bathroom, along with the installation of tankless water heaters for all units.

Between 2020 and 2021, the building underwent comprehensive updates including multiple unit renovations (kitchen and bathroom remodels in units 2 and 3), window replacements, and electrical upgrades including a new 200-amp main service installation. The property has faced recurring plumbing issues, particularly regarding sewer problems, with multiple complaints and repairs documented between 2002 and 2014, though more recent records suggest these issues have been addressed. The building's maintenance history reveals some concerning recent issues, particularly regarding water intrusion, with complaints filed in late 2024 about improper rainwater drainage affecting neighboring properties.

This suggests ongoing external water management challenges. The property has maintained compliance with fire safety requirements, with no recent violations, though there was a historical violation related to fire extinguisher maintenance in 2002 that has since been resolved. Historical records from 2002 show various building code violations that were promptly addressed, including issues with windows, security devices, stairs, and garbage receptacle placement. Recent 311 calls primarily relate to parking issues, tree maintenance, and general city services rather than building-specific concerns, indicating that while the property has required substantial repairs and upgrades over the years, the owner has generally addressed building code violations and maintenance issues as they arise.
