Initial analysis

The three-unit multi-family residential building at 205-209 Webster Street in Hayes Valley is a three-story flats and duplex structure built in 1900, currently owned by Rex Chiu Hung and May Chan Ch. The property has undergone several maintenance and improvement projects over the years, including a kitchen and bathroom remodel in 2001 valued at $12,000, reroofing in 1988, and two street space permits issued in 2015. The building has been subject to routine housing inspections in 2005 and 2016, and has experienced several maintenance issues over its history, including a 1999 complaint about defective heating, window sealing problems, and sanitation concerns, which were all resolved within a month.

More recent building-specific issues were reported in 2011 when blocked exits and the presence of combustible materials were noted, though these conditions were promptly corrected the same day. The property's external environment has faced some challenges, as evidenced by 311 calls between 2015 and 2020, primarily related to sidewalk cleanliness issues including reports of loose garbage and waste, as well as instances of graffiti in 2017, all of which were addressed by city services. While the building has experienced various maintenance concerns over the years, most reported issues have been resolved in a timely manner, and there have been no reported building-specific complaints since 2016. The property appears to be subject to regular housing inspections, with the most recent routine inspection occurring in 2016.

Risk rating

How 205-209 Webster 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
49th percentile

Out of 1027 buildings in this neighborhood, 524 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.

Building age

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

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 53.6%
Moderate concern 19.4%
Severe concern 26.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
