Initial analysis

The 7-unit, 3-story apartment building at 1106-1112 Plymouth Ave in the Ingleside neighborhood, built in 1926, has undergone several significant improvements and faced various challenges over recent years. Most notably, in 2023, the building received a comprehensive fire alarm system upgrade to comply with current safety standards, including the installation of low-frequency sounders in sleeping areas. Unit 5 was recently renovated in 2022, receiving bathroom and kitchen updates along with electrical improvements, including a new subpanel and partial rewiring. The building has experienced recurring maintenance issues, particularly in 2016 when multiple violations were documented, including egress obstructions, stairway concerns, and fire safety deficiencies, though these were mostly resolved by early 2017. A series of water heater replacements have been performed between 2012 and 2016, and there were several electrical system upgrades, including the replacement of multiple subpanels in 2014.

The building's history includes some concerning events, particularly during 2016-2017, with multiple complaints related to mold, water leakage, and unauthorized modifications. While most violations were abated, they indicate periods of significant maintenance challenges. More recent improvements, particularly the 2023 fire alarm system upgrade and the 2022 Unit 5 renovation, suggest ongoing maintenance and safety improvements by ownership. The building's systems appear to have received regular attention, with multiple water heater replacements and electrical system upgrades over the years.

Risk rating

How 1106-1112 Plymouth 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 156 buildings in this neighborhood, 123 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.

Building size

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

12-Month severity forecast
No violation 35.9%
Moderate concern 30.9%
Severe concern 33.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
