Initial analysis

The 48-unit, 2-story multi-family residential building at 1327 Leavenworth Street in Nob Hill, owned by Nancy Toy Ng Survivors Trust, was constructed in 1906 and has undergone several significant modifications and repairs over the years. Most notably, the building completed its mandatory soft-story retrofit in 2020, which included first-floor shear wall improvements, demonstrating compliance with seismic safety requirements. The property has experienced recurring maintenance issues, particularly with water-related problems, as evidenced by multiple complaints in 2015-2018 regarding water damage, mold, and plumbing issues. A significant pattern of unpermitted work was identified in 2015 related to a bathroom renovation, though this was subsequently addressed through proper permits and repairs costing $15,000. The building has faced ongoing fire safety compliance challenges, with multiple violations and complaints regarding alarm systems, sprinklers, and extinguishers between 2016 and 2023, including an open violation for sleeping area requirements as of December 2023. Infrastructure maintenance has been periodically addressed, including a boiler water leak repair in 2015 and various street space permits over the years. Recent 311 calls in 2024 suggest ongoing issues with debris around the property, though these were resolved promptly. The building's historical records from the 1990s show earlier maintenance efforts such as reroofing and foundation work, indicating long-term attention to structural integrity.

Risk rating

How 1327 Leavenworth 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
4th percentile

Out of 1125 buildings in this neighborhood, 1080 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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

12-Month severity forecast
No violation 18.8%
Moderate concern 40.6%
Severe concern 40.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
