3424 24th St, San Francisco, CA 94110

The 6-unit, 3-story multi-family residential building at 3424 24th Street, owned by Aventura By Mission LLC, was originally constructed in 1916 and is undergoing significant improvements as of 2021-2023. Recent major projects include a voluntary seismic retrofit (cost: $100,000) and the addition of two new dwelling units (Units #7 and #8) on the basement floor with comprehensive interior improvements (cost: $300,000). The building is also receiving extensive modernization, with the installation of tankless water heaters for all units, reconfiguration of existing units' layouts, and proposed addition of a roof deck.

Historical maintenance records from 2001 and 2007 reveal various fire safety and building maintenance issues, including problems with fire escapes, smoke detectors, and building stairs, though these violations were subsequently abated. The property experienced multiple fire code violations in 2021, specifically related to fire extinguishers and alarm systems, all of which were addressed. A notable tenant buyout occurred in 2022, with two tenants receiving $115,000 in compensation.

The building's recent activity has primarily focused on major renovations and safety improvements, with multiple building permits issued in 2021 covering interior reconfigurations and infrastructure upgrades. Recent 311 calls from 2023-2024 indicate some ongoing issues with sidewalk conditions and parking enforcement, though these are primarily street-related concerns rather than building-specific problems. The building's electrical infrastructure was upgraded in 2004 with 100-amp service installation, and several routine inspections by Housing Inspection Services have been documented over the years. The property's recent seismic retrofit and ongoing improvements suggest significant investment in modernization and safety upgrades, while the resolution of historical violations indicates improved maintenance standards.
