3901-3909 Cesar Chavez St, San Francisco, CA 94131

The two-story, four-unit apartment building at 3901-3909 Cesar Chavez St in Noe Valley, built in 1923 and currently owned by the Colin Horn Trust I, has undergone several significant improvements and faced various maintenance challenges over its history. The building has received important infrastructure upgrades, including a complete electrical system modernization in 2006 with 200 amp service installation and four meter/circuit breaker panels, and sewer line repairs in 2017. Historical improvements include a fireproof roof deck installation in 1985 and comprehensive code compliance work completed in 1987.

A notable cluster of violations was recorded in 2001, primarily related to lead paint hazards, security issues, and stair repairs, though all were successfully abated by October 2001. The building's maintenance history shows attention to critical systems, with a reroofing project documented in 1997, though this permit has since expired. Recent concerns regarding the property's immediate surroundings have emerged, with multiple 311 calls between 2024-2025 reporting issues such as sewage discharge, garbage accumulation, and noise complaints.

These cases appear mostly related to street-level conditions rather than building-specific problems, with several being promptly resolved by city services. The property's historical inspection record from the late 1990s revealed various maintenance issues, including problems with windows, kitchen cabinets, flooring, smoke detectors, and exterior conditions, though these were generally addressed through subsequent repairs. While the building has experienced periodic maintenance challenges over the years, particularly in the late 1990s and early 2000s, recent records indicate fewer building-specific violations, with most recent issues relating to external conditions rather than structural or safety concerns within the building itself.
