Initial analysis

The property at 331-333 Douglass Street is a two-unit, one-story multi-family residential building constructed in 1907, currently owned by Richard K Lui. The most recent significant improvement was a $16,000 reroofing project completed in July 2024. The building underwent substantial renovations in 2016, including replacement of outdoor steps and decks, window upgrades, and the installation of a heat pump, with related electrical and plumbing work completed. Earlier improvements from 2015-2016 involved comprehensive remodeling of kitchen and bathroom facilities in one unit, including new fixtures and electrical systems.

The property has experienced some regulatory challenges, particularly in 2010-2012 when violations were noted regarding an unpermitted shed construction in the rear yard, which was ultimately abated in 2012. A violation for garbage accumulation was recorded and resolved in 2016. Recent maintenance issues have been reported through 311 calls, including concerns about toters being left out continuously and various parking violations in the vicinity between 2021-2024, though these are primarily municipal enforcement matters rather than building-specific issues. The building's history includes an unsuccessful attempt in 2005 to demolish and reconstruct the two-family dwelling, indicating that the existing structure has been maintained rather than replaced.

Risk rating

How 331-333 Douglass 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
92th percentile

Out of 1278 buildings in this neighborhood, 102 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.

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.

Director's hearing rate, owner's portfolio

Per-building rate of director's hearings across the owner's portfolio.

12-Month severity forecast
No violation 85.2%
Moderate concern 11.0%
Severe concern 3.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
