Initial analysis

1326 20th Avenue is a 10-unit, 3-story multi-family residential building built in 1965, currently owned by Lin Grace, located in the Central Sunset neighborhood. The property has undergone several significant improvements in recent years, most notably a comprehensive seismic retrofit project in late 2023, which included the addition of multiple shearwalls across all floors to enhance structural stability. In September 2024, the building addressed moisture ingress issues by replacing three windows on the front facade and repairing the stucco wall. The building has a documented history of water-related maintenance issues, including past window leaks (2010, 2012) and water damage repairs, though recent window replacements suggest these issues are being proactively managed.

The property has experienced various maintenance and safety inspections over the years, with several fire safety system-related violations and corrective actions recorded between 2006 and 2023, including issues with alarm systems, extinguishers, and blocked exits. While historical violations from 2000 related to fire safety and interior surfaces were resolved promptly, the building has generally maintained compliance with housing codes since then. Recent inspections have noted sidewalk defects (2024) and occasional issues with street cleanliness (2023) outside the building. The property underwent a routine apartment inspection in 2014, and several building improvements have been documented over the years, including roof replacements and window repairs. Recent maintenance activities, such as seismic retrofitting and window replacements, suggest active building management and investment in property upkeep.

Risk rating

How 1326 20Th 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
2th percentile

Out of 814 buildings in this neighborhood, 798 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 16.1%
Moderate concern 26.6%
Severe concern 57.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
