Initial analysis

The two-unit residential building at 49-51 Montezuma Street in Bernal Heights, owned by Jeremy B Bloch, is a two-story flats and duplex structure built in 1900. The building's maintenance history shows several significant structural interventions in the late 1980s and early 1990s, including repairs to rotten floor joists and brick foundation work in 1990, and grading adjustments to address dirt issues around floor joists in 1989. More recent concerns include an active complaint from 1999 regarding an improperly located water heater in a bathroom, which was still listed as active in the records, and a 2011 complaint about non-code-compliant property line windows that were reportedly not fire rated, though this complaint was quickly abated the following day.

The property has experienced multiple public works-related incidents over the past several years, with the most recent being a December 2023 complaint currently marked as open. A noteworthy cluster of issues occurred in 2021-2022, including cases of improper toter management, pavement defects, and various other street and sidewalk maintenance concerns, many of which were resolved through outreach, enforcement, or cleaning efforts. While these service requests and complaints provide insight into the building's surrounding environment, they primarily relate to street-level issues rather than direct building concerns. The building's permit and complaint history suggests attention to structural maintenance in the late 20th century, with limited documentation of interior improvements or major renovations in recent decades.

Risk rating

How 49-51 Montezuma 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

Out of 1276 buildings in this neighborhood, 204 are predicted to be safer.
