Unlock complete reportThe three-story, six-unit apartment building at 190 27th Avenue, owned by Jimmy Lam and constructed in 1921, has undergone several significant upgrades and maintenance work in recent years. Most notably, the building completed a mandatory soft-story retrofit in 2016 (Tier 3) with an $80,000 foundation upgrade and wall reinforcement, and a $25,000 reroofing project was finished in 2023. Between 2021 and 2022, substantial interior improvements were made, including kitchen and bathroom remodels in units 3 and 5, comprehensive electrical rewiring, and an electrical service upgrade to 400 amps with 8 meters/panels. The building has experienced recurring boiler permit issues, with the most recent active complaint from May 2022 regarding an unrenewed boiler permit. Fire safety systems have required ongoing attention, with recent fire safety violations in 2023 related to extinguishers and alarm systems, though these were marked as "Condition Corrected." Historical maintenance issues include multiple instances of dry rot repairs between 2003-2008, window replacements in 2009, and termite repairs in 2008. The building has had various fire safety inspections and violations between 2017 and 2023, primarily related to alarm systems and extinguishers, with most issues being resolved through correction notices. A tenant buyout occurred in December 2020, involving two tenants for $20,000. Recent 311 calls have primarily concerned street-level issues such as garbage cleanup and parking violations, with no major building-specific complaints since 2022.

How 190 27Th Ave'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.
Out of 660 buildings in this neighborhood, 561 are predicted to be safer.
