Initial analysis

The 4-unit, 2-story multi-family residential building at 770 Monterey Blvd in the Sunnyside neighborhood was built in 1954 and is currently owned by Leong K & Wai Sui Wong Exem. The property has a history of maintenance and compliance issues, with significant events including repairs to rear stairs due to dry rot in 1997, reroofing in 1996, and a major compliance update in 1985. A concerning pattern of violations emerged in 2010 when the building was designated as a "nuisance" under Section 1001-d of the San Francisco Housing Code, with multiple violations related to paint conditions, including lead hazard concerns, weatherproofing, and general maintenance issues. This followed earlier violations in 2003 related to wooden stairs and decks, and in 2000 involving fire extinguisher maintenance. While all these violations were eventually abated, they suggest ongoing maintenance challenges.

More recently, from 2023-2024, there have been several infrastructure and maintenance concerns reported through 311 calls, including issues with property-damaging trees, sidewalk defects, and garbage management problems. Of particular note in 2024, there were multiple reports about tree roots lifting sidewalks, though these remain open as of the latest updates. The building has undergone regular housing inspections, with all issues ultimately resolved, though the frequency of routine inspections and subsequent violations suggests a history of periodic maintenance challenges that required attention. The most recent building-related works before the current complaints involve exterior maintenance issues focusing on weatherproofing and paint conditions.

Risk rating

How 770 Monterey Blvd'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
41th percentile

Out of 129 buildings in this neighborhood, 76 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 location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 31.2%
Moderate concern 18.9%
Severe concern 49.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
