Initial analysis

The 5-unit, 3-story multi-family residential building at 1821-1823 Oak Street in Haight Ashbury, constructed in 1900, has undergone several significant improvements over recent years, most notably completing a mandatory soft-story seismic retrofit in 2017 at a cost of $107,000. The property has experienced various maintenance and safety issues, with a notable cluster of violations recorded in October 2012 that required repairs to stairs, window hardware, damaged walls, and sanitation concerns, as well as addressing lead paint safety requirements - all of which were abated by January 2013. Subsequent improvements included a kitchen remodel in Unit A in 2014, replacement of a furnace in 2013, and various electrical and plumbing upgrades. The building had some concerning habitability issues reported in 2013, including lack of heating and mold problems, though these were marked as not active by early 2014.

More recent history shows ongoing maintenance and compliance efforts, including a completed underground electrical service upgrade in 2004 (now expired), roof replacement in 2005, and periodic structural and system upgrades. Recent 311 calls (2022-2024) primarily relate to exterior maintenance and waste management issues, particularly regarding toter placement and street cleaning needs, which have been addressed through city enforcement and resolution processes. The property has not experienced any recorded fire incidents with civilian injuries. The completed soft-story retrofit places the building in compliance with current seismic safety standards, though its Tier 3 designation indicates it was previously considered a higher risk structure.

Risk rating

How 1821-1823 Oak 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
58th percentile

Out of 581 buildings in this neighborhood, 244 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.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 64.3%
Moderate concern 15.1%
Severe concern 20.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
