Initial analysis

The property at 1131-1133 Anza Street is a two-unit residential building located in San Francisco's Inner Richmond neighborhood. Built in 1914, this two-story flats and duplex structure is currently owned by Frank Zhang. Significant recent activity on the property centers around proposed redevelopment plans, with multiple demolition and construction permits filed in August 2021 for the demolition of the existing building and construction of a new four-story structure with two units and an accessory dwelling unit (ADU). These permits were filed under the same number (202108257076) and appear to be duplicated in the records, suggesting either an administrative error or multiple identical applications.

The building's maintenance and incident history shows attention to basic upkeep, including a reroofing project in 2002, though this permit has since expired. Various 311 calls from 2013 to 2024 document neighborhood issues such as sidewalk defects, encampments, graffiti, street cleaning needs, and tree damage, though these incidents primarily relate to the surrounding area rather than the building itself. The most recent calls from 2023 and 2024 involved a damaged tree and sidewalk parking, respectively. The property has gone through multiple planning review stages regarding the proposed redevelopment, with some records showing the applications as "Under Review" while others indicate they were "Closed - Withdrawn," though it's unclear if this withdrawal was definitive or administrative in nature.

Risk rating

How 1131-1133 Anza 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
