Initial analysis

The two-unit multi-family residential building at 27 14th Avenue, owned by Viotti Living Trust, has undergone several significant maintenance and infrastructure improvements since its construction in 1940. The property received notable updates to its mechanical systems, including the installation of a new York furnace in 2021, sewer replacement work in 2020, and the addition of a gas line for a stove in 2015. A plumbing permit for a 40-gallon water heater installation from 2014 is recorded as expired, though it may have been completed without further notification. The building's electrical infrastructure was modernized in 2003 with the installation of underground conduit for electrical service as part of a PG&E underground conversion project.

The property has experienced recurring sewer-related issues, with documented sewage backup incidents occurring in 2014, 2016, 2018, 2019, and most recently in 2020, suggesting an ongoing challenge with the building's sewer lines that may require monitoring. Other significant events affecting the property's immediate environment include a series of 311 calls regarding the surrounding public areas, such as human/animal waste (2023), a Christmas tree removal request (2022), and a construction plate issue (2017). The most recent incidents include parking enforcement (2024), though this was unable to be located by responding officers. While the building has received necessary upgrades over the years, the repeated sewer issues stand out as the most significant pattern in the property's maintenance history.

Risk rating

How 27 14Th 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
83th percentile

Out of 660 buildings in this neighborhood, 112 are predicted to be safer.
