Initial analysis

The property at 50-52 Sadowa Street in Oceanview is a century-old, one-story multi-family residential building constructed in 1910, currently owned by Ben K Lew & Angela Ma Revoc. The building underwent significant renovations in 2010-2011, including a conversion from a single-family to a two-family dwelling, kitchen and bathroom remodels in both units, and substantial garage improvements totaling over $40,000. In 2012, the property faced several compliance issues, most notably regarding an unauthorized 10-foot fence construction in the rear yard, which resulted in violation notices and abatement proceedings that were ultimately resolved by 2014. The garage area has also been a recurring compliance concern, with violations noted in 2011 regarding work beyond permitted square footage and unpermitted concrete paving.

Most recently, in 2024, the owners are addressing compliance issues related to tree planting requirements established in 2021, with new permits filed to plant trees and modify the curb cut and sidewalk area. The property has experienced various maintenance and parking-related incidents in recent years, including multiple reports of driveway blocking and some sidewalk/pavement defects, though these issues have generally been resolved promptly. The building's recent history shows proactive efforts by the current owners to address compliance issues, though there have been periodic concerns regarding parking management and property maintenance in the surrounding area.

Risk rating

How 50-52 Sadowa 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 79 buildings in this neighborhood, 6 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.

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 73.7%
Moderate concern 17.1%
Severe concern 9.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
