Initial analysis

The property at 4021-4025 Irving St in the Outer Sunset neighborhood is a two-story, double-dwelling residential building owned by Barry D Wong & Doris J Lee. The building has undergone several significant renovations over the past decade, with the most recent major work being a roofing project in 2021 costing $15,640. In 2016, substantial improvements were made to the front building, including the addition of a bedroom, family room, and full bathroom on the first floor, along with the replacement of a gas furnace, with similar electrical and plumbing upgrades completed through proper permits. Prior to that, in 2013, the rear building received a complete kitchen remodel including new cabinets, fixtures, and electrical work. The building has experienced one notable set of violations in December 2004, when complaints were filed regarding malfunctioning heating systems and doorbells, though these issues were resolved by February 2005.

The property has maintained an active 311 call record primarily related to parking issues, with multiple citations issued for parking violations between 2019 and 2023, including several cases of driveway blocking and sidewalk parking. There were also some municipal service calls for street cleaning in 2016 and pavement defects in 2015, as well as graffiti removal in 2013, all of which were successfully resolved. The most recent planning record from 2020 indicates a completed project involving a full bathroom installation with limited access, though this appears to be an older modification relative to more recent improvements documented in the building permits.

Risk rating

How 4021-4025 Irving 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
62ndpercentile

Out of 632 buildings in this neighborhood, 240 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

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.
