Initial analysis

The property at 1257-1259 Montgomery Street is a two-story, three-unit multi-family residential building constructed in 1940 in Telegraph Hill, currently owned by Dong Ventures LLC. The building has undergone several significant renovations, most notably in 2002 when major improvements were made including window replacements, kitchen and bathroom renovations, and the installation of two furnaces and a water heater, with work totaling approximately $29,750. Earlier, in 2000, there was an attempt to install nine vinyl windows, though those permits expired. The building has experienced some maintenance issues, with two notable plumbing incidents on record: a sewer leak in 2003 at the neighboring 319 Union Street, which was promptly addressed within a week, and a more recent complaint from February 2023 regarding plumbing and appliance issues on the second floor, though this case is listed as not active.

The property has had various maintenance and service calls between 2019 and 2022, including water service requests in 2021, graffiti removal, and illegal posting violations in 2020, all of which were resolved. Historical renovation work from the early 2000s suggests significant investment in building improvements, though the relatively recent plumbing complaints may warrant attention. The record shows regular municipal interactions through 311 calls, primarily relating to building maintenance, parking violations, and street-related issues, all of which were addressed by the respective city departments. While the building appears to have maintained compliance with major housing regulations, the pattern of water-related service requests and the 2023 plumbing complaint might indicate ongoing infrastructure considerations.

Risk rating

How 1257-1259 Montgomery 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.
