Initial analysis

151-153 4th Avenue is a two-unit, two-story multi-family residential building located in the Lake-Presidio neighborhood, constructed in 1923 and currently owned by the Irene C Sun Living Trust. The property has undergone several significant improvements in recent years, most notably in early 2023 when windows were upgraded (though the permit for this work was withdrawn, originally proposing to change materials from wood clad to wood comp) and when the gas furnace was replaced. A comprehensive renovation of the first floor was completed in 2013, including kitchen remodeling with new cabinets, countertops, appliances, and electrical upgrades, which involved rewiring extensive electrical systems including outlets and lighting.

The building's maintenance history shows attention to essential systems, including a 150-amp electrical service upgrade in 2013. There was one documented water leak issue in 2011 affecting unit 153, which was resolved in 2012, and no fire incidents or civilian injuries have been recorded. The property has experienced recurring issues with illegal parking and driveway blocking in the vicinity, with numerous citations issued between 2018 and 2023, indicating ongoing challenges with street parking enforcement in the area. The most recent parking-related incident was recorded in November 2023. Two historical permits from the 1980s (one to remove an illegal apartment in 1985 and another that was cancelled in 1981) are on record, though their relevance to the current property condition is minimal given their age.

Risk rating

How 151-153 4Th Ave'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
93th percentile

Out of 660 buildings in this neighborhood, 46 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 88.6%
Moderate concern 9.3%
Severe concern 2.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
