Initial analysis

The 839 Post Street building, a 53-unit 6-story multi-family residential property built in 1925 and owned by California West Associates, has undergone several significant renovations and faced various challenges over the past years. Most recently, in March 2024, comprehensive kitchen and bathroom renovations were completed, including plumbing and electrical work. The building has seen important safety improvements, including a voluntary fire alarm system replacement in 2022 to comply with San Francisco Fire Department requirements, and structural strengthening work completed in 2014 valued at $500,000. However, the property has experienced recurring fire safety concerns, with violations noted in 2023 regarding sleeping area requirements and alarm system maintenance, as well as historical issues with sprinkler/standpipe systems and fire alarms dating back to 2009.

The building has faced multiple maintenance and habitability challenges, particularly in 2017 and 2022, when water damage affected multiple units and hallways. The 2017 complaints revealed various interior issues including water damage, damaged walls and ceilings, and problems with weatherproofing. Earlier violations from 2002 documented issues with windows, including security concerns with non-functioning locks and drafts. A concerning pattern of problems emerged in the 1990s-2000s regarding paint conditions, including a 1998 complaint about chipping paint and asbestos concerns. More recent months have shown ongoing attention to building surroundings, with multiple 311 calls in late 2024 regarding garbage, debris, and environmental concerns outside the building. While many historical violations have been resolved and conditions improved through various repairs and upgrades, the building's maintenance history demonstrates periodic challenges with both unit interiors and building systems requiring attention and remediation.

Risk rating

How 839 Post 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

Out of 448 buildings in this neighborhood, 354 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 4.9%
Moderate concern 79.0%
Severe concern 16.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
