Initial analysis

The 15-unit, 2-story apartment building at 1345 20th Avenue in San Francisco's Central Sunset neighborhood, owned by the Moriarty Family Revocable Trust, was constructed in 1951 and has undergone several significant safety and maintenance upgrades over the years. Most notably, the building successfully completed its mandatory soft-story retrofit in 2017 under Tier 3 requirements, and the fire alarm system was upgraded in 2021-2022 to include modern features such as horn/strobes, low-frequency sounders in sleeping rooms, and remote monitoring capabilities. Recent maintenance work has included repairs to dry-rotted areas of rear wood decks in 2022 and various routine upkeep such as reroofing projects in both 1988 and 2009.

The building's history shows some past safety concerns that have been addressed, including multiple fire alarm system issues in 2006 and 2009 which were corrected, and a routine housing inspection in 2002 that identified several deficiencies including problems with the fire escape ladder, backyard stairs, and gas shutoff equipment - all of which were subsequently abated. Recent inspections have shown generally good compliance, though there was a temporary violation regarding soft-story retrofit compliance in 2019 which was resolved by 2020. The property has experienced some parking-related issues in the surrounding area, with multiple citations for sidewalk parking and driveway blocking between 2023-2024, and there have been several 311 calls related to street cleaning and sidewalk maintenance, including an open case for a collapsed sidewalk from May 2023. A recent fire complaint from September 2024 regarding blocked exits was determined to have no merit, and the building's fire safety systems appear to be currently functioning properly, with no recent fire incidents or civilian injuries reported.

Risk rating

How 1345 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

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 11.5%
Moderate concern 64.2%
Severe concern 24.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
