Initial analysis

The property at 35-37 Norton Street in Mission Terrace is a two-story, 3-unit multi-family residential building constructed in 1915, currently owned by Golden Properties LLC. The building has a significant history of unpermitted modifications and subsequent enforcement actions, most notably in 2018 when the city issued a notice regarding an unauthorized dwelling unit conversion, prompting the filing of permits to legalize the unauthorized modifications. Earlier violations in 2010 documented the illegal conversion of a garage space into a separate dwelling unit, which was addressed through permits and completed work to remove unauthorized kitchen and bathroom facilities. The building has experienced persistent maintenance issues, including multiple reports of water leaks, mold, and ceiling damage between 2016 and 2018, with the most recent complaints indicating problems including insects, rodents, and possible structural concerns with a retaining wall.

Recent activity at the property has primarily involved parking-related issues, with multiple reports of illegal parking and driveway blocking reported between November 2024 and January 2025. There was also an incident involving sidewalk defects due to tree root uplift in November 2024. While the building has undergone various repairs and improvements over the years, including a kitchen remodel and window replacements in the 1980s, its history of unauthorized modifications and subsequent compliance efforts suggests ongoing challenges with maintaining proper building code compliance. The most recent active violation from 2018 indicates unresolved issues regarding unpermitted plumbing, electrical work, inadequate heating, and improper occupancy arrangements, particularly concerning the conversion of garage space into additional living units.

Risk rating

How 35-37 Norton 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
16th percentile

Out of 149 buildings in this neighborhood, 125 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.

DBI complaint rate, owner's portfolio

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

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 37.8%
Moderate concern 25.6%
Severe concern 36.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
