The property has undergone significant renovations over the years, with the most recent major work being a fire alarm system upgrade in October 2024 costing $26,867 to comply with SFFD requirements. Recent complaints in 2024 and 2022 have centered around unauthorized awning modifications by "Alegre Home Care," while a 2021 complaint highlighted concerns about sound insulation between units. Historical improvements include a 2014 renovation of Unit 5 ($36,000) that included living room conversion, bathroom, and kitchen remodels, as well as various safety-related upgrades such as fire alarm and sprinkler system improvements.

The building has experienced several fire safety concerns over the years, with multiple violations and complaints regarding alarm systems, fire extinguishers, and exit maintenance between 2011 and 2024. Notably, there is currently an open violation from October 2023 regarding sleeping area requirements. The property has undergone various apartment modifications, including the controversial conversion of Unit 4 from one bedroom to two bedrooms in 2009-2011, which generated complaints about construction procedures and unit size. The building's maintenance history shows regular updates to systems and units, including window replacements, kitchen and bathroom remodels, and safety system upgrades, though there have been some periods requiring attention to compliance issues, particularly regarding fire safety systems. Recent 311 calls from 2023-2024 mostly pertain to parking issues and street cleaning matters, with some graffiti incidents recorded.

Risk rating

How 3419-3421 Geary Blvd'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.
