Initial analysis

The two-unit residential building at 1-5 Nantucket Avenue in Mission Terrace, owned by the Marta Lopez 2009 Revocable Trust, is a two-story flats and duplex structure built in 1961. Historical records show minimal major improvements, including a roof replacement in 1998 (permit expired) and window installations in 1991 (completed).

The property has experienced several infrastructure and maintenance issues in recent years, as evidenced by multiple service requests between 2024 and 2025. Most notably, there is an open sidewalk defect from December 2024 caused by tree roots, and an exposed power pole wire reported in June 2024 that remains unresolved. The building's surroundings have been affected by recurring issues with garbage and debris, with several cleaning calls recorded in early 2024. Multiple complaints about driveway blocking in mid-2024 were addressed by parking enforcement, and there was a water-related issue involving a fire hydrant in July 2024 that has since been resolved. A false fire alarm incident was recorded with no civilian injuries. While these service calls indicate ongoing maintenance and access challenges in the immediate vicinity, they primarily relate to exterior and public infrastructure rather than the building's internal systems or structure.

Risk rating

How 1-5 Nantucket 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
74th percentile

Out of 149 buildings in this neighborhood, 39 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 58.6%
Moderate concern 22.7%
Severe concern 18.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
