Initial analysis

The 6-unit, 3-story multi-family residential building at 1471 California Street in Downtown, owned by Michael L. Louie, has experienced several significant maintenance and safety events since its construction in 1911. Most recently, the building has faced multiple sanitation and maintenance challenges in 2024, with numerous 311 calls related to garbage and debris cleanup, including concerns about human waste and mattress removal. The property has undergone several substantial infrastructure improvements over the years, including a complete waste and vent system replacement for all six units in 2011, street space and sidewalk repairs in 2008, and reroofing work in 2002. A series of building violations were documented in November 2009 related to fire safety, heating system maintenance, interior surfaces, and security requirements, though all were abated by December 2009. Earlier issues from 2002 concerning window glazing were also resolved. The building has experienced three fire department responses to alarm system malfunctions between 2022 and 2023, though thankfully none resulted in civilian injuries or confirmed fires.

The property's maintenance history shows consistent attention to basic infrastructure needs, though the recent cluster of 311 calls in 2024 suggests some ongoing exterior maintenance challenges. The building's major systems have received periodic upgrades, such as the planned addition of an extra meter panel in 2006 (though this permit was cancelled), and multiple improvements to meet safety and building code requirements. While the 2009 violations represented a notable cluster of issues, these were addressed within two months, and the building has not had any documented recurring violations in recent years. The most recent building inspections and permits indicate active maintenance of basic systems, though the frequency of recent sanitation-related 311 calls suggests occasional challenges with exterior upkeep.

Risk rating

How 1471 California 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.

Neighborhood percentile
