Initial analysis

The 6-unit, 3-story multi-family residential building at 2954-2958 21st Street in the Inner Mission, owned by Old Forge LLC, has undergone several significant renovations and faced various maintenance challenges since its construction in 1907. Most notably, the building is currently non-compliant with the mandatory Tier III soft-story seismic retrofit requirements, with an active complaint filed in 2020 regarding failure to comply with San Francisco Building Code Chapter 5. Recent improvements include multiple window replacement projects in 2024, with permits issued for 6 retrofit vinyl windows and 9 wood-clad aluminum windows, suggesting ongoing efforts to improve energy efficiency and building aesthetics. The building has undergone substantial structural work in recent years, including a 2015 horizontal addition at the rear with new exterior egress stairs, decks for three units, and a 2017 soft-story retrofit amendment to bring the first story structural upgrades into compliance with seismic requirements.

Historical maintenance issues are documented through numerous building complaints and violations, particularly between 2000 and 2018, including problems with stairs, water heaters, windows, and various plumbing and electrical issues. The building experienced multiple incidents of water damage, heating problems, and mold issues between 2003 and 2011, though many of these violations have been marked as abated. Recent plumbing work in 2024 included the installation of six automatic gas shut-off valves, indicating attention to safety systems. The property has faced maintenance challenges related to garbage and debris, as evidenced by multiple 311 calls between 2021 and 2024, though these are primarily related to exterior conditions rather than building systems. A recent complaint regarding excessive noise was submitted in October 2024 and is currently open.

Risk rating

How 2954-2958 21St St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
