516-520 Anza St, San Francisco, CA 94118

The 5-unit multi-family residential building at 516-520 Anza Street in Lone Mountain, owned by Romero Trust, has a history spanning over 100 years since its construction in 1916. The building has undergone several significant improvements to maintain safety and habitability, most notably major structural work in 2011 addressing dry rot issues in the garage and deck/stairs, along with concrete repouring and framing repairs. The property has faced recurring maintenance challenges, with multiple heating system concerns, including an active complaint from January 2025 about a tenant's lack of heat, and past violations related to heating systems in 2004.

The building experienced a cluster of violations in early 2002 related to lead paint hazards, smoke detection, plumbing issues, and water damage, all of which were abated by April 2002. Between 2003-2004, there were several concerning complaints regarding water damage, mold, and plumbing issues, though these were subsequently resolved. Recent activity has focused on routine maintenance and inspections, with multiple electrical upgrades in the mid-2000s, including replacing old fuse boxes with circuit breaker panels.

The building's history includes some unauthorized modifications, such as a complaint in 2004 regarding unpermitted storage area conversion to an additional unit, though this may have pertained to the legal conversion of the basement unit completed in 1990. The property has experienced relatively few fire-related incidents, with only minor alarm system activations and medical assists recorded. Recent 311 calls have primarily concerned external issues such as abandoned furniture and debris on the property, with several resolutions between late 2024 and early 2025. The building's current status shows some ongoing maintenance needs, particularly regarding the heating system, while the overall pattern of complaints suggests that most historical issues have been addressed through regular inspections and permit-driven improvements.
