Initial analysis

The property at 64-66 Deming Street is a two-unit, two-story multi-family residential building constructed in 1927, currently owned by the Souza Mary Revocable Trust. The building has undergone several significant improvements and faced various regulatory challenges in recent years. Most notably, between 2015 and 2023, there was a series of violations and compliance actions related to an unauthorized dwelling unit above the garage, which was ultimately abated through a Conditional Use Authorization process. The building has seen substantial window upgrades, with the most recent permits in 2024 replacing multiple windows at the front and side of the building, following a $35,248 window replacement project completed in 2023.

Other notable improvements include the replacement of decayed timbers and restoration of a rear deck in 2018, kitchen and bathroom renovations in 2010, and the legalization of storage areas and bathroom facilities in 2022, which involved associated electrical and plumbing work. The property has maintained an active maintenance schedule, with records showing regular updates to electrical systems, including a significant kitchen remodel and garage service upgrade in 2005, and plumbing improvements such as house trap replacement in 2020. Recent 311 calls from 2023-2024 have primarily concerned external issues such as street cleaning, graffiti, and parking violations, rather than building-specific problems, suggesting that more recent years have seen fewer complaints about the building's condition or maintenance.

Risk rating

How 64-66 Deming 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
