Initial analysis

227 Clinton Park is a 2-story, 4-unit multi-family residential building located in Mission Dolores, constructed in 1963 and currently owned by David J Jr & Barbara M Sanc. The property has undergone several significant renovations over the years, with the most recent work completed in September 2023 involving a comprehensive remodel of Unit #4's bathroom and kitchen, including plumbing and electrical updates, at a cost of $45,000. Prior to this, Unit #2 received similar treatment in 2019, including kitchen and bathroom improvements. The building has a documented history of maintenance issues, particularly notable in September 2003 when multiple violations were recorded regarding interior surfaces, including problems with window sashes, walls, floors, and handrails, as well as plumbing and electrical concerns. All these violations were abated by October 29, 2003.

More recent history shows some ongoing infrastructure challenges, with two sewage-related incidents reported through 311 calls - one in October 2024 and another in April 2022. The building underwent a re-roofing project in 2000 and had several routine housing inspections between 2003 and 2011, with one complaint in 2019 regarding unpermitted demolition work in the garage area. The property has been subject to periodic inspection results, with some concerns about weatherproofing, door closures, and handrails noted in a 2007 complaint, though these issues were resolved. The recent improvements to Units #2 and #4 suggest ongoing maintenance and upgrading of the building, with no active violations or complaints on record since 2019. The building's documented history shows a pattern of addressing maintenance issues promptly, with all recorded violations being resolved.

Risk rating

How 227 Clinton Park'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 799 buildings in this neighborhood, 503 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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 55.3%
Moderate concern 20.9%
Severe concern 23.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
