Initial analysis

The property at 527-529 26th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1919, this flats and duplex building has undergone several significant modifications and faced multiple regulatory challenges over the past four decades. Most recently, in 2023, there was a repair needed for a leaking window on the third floor that required relocation to the southern elevation of the building at a cost of $3,000. The building has a concerning history of unauthorized unit conversions and modifications, with multiple complaints and violations recorded between 1997 and 2020 regarding illegal dwelling units, including a particularly troubling situation in 2015-2020 involving suspected illegal unit conversions and Airbnb usage. The property owner has also faced scrutiny for an unauthorized 200 sq. ft. detached structure in 2014 that was built without proper permits.

The building has experienced recurring issues with water intrusion, most recently documented in December 2022 when a section of siding fell off, allowing water and pests to enter, though this complaint was eventually closed. Older permits show various structural modifications, including attempts to convert the property from single-family to multi-family use in the 1980s, along with parking modifications. The property has also generated multiple 311 calls in 2024, primarily related to parking violations and street cleaning issues, though these are more related to neighborhood conditions than building-specific problems. In terms of planning records, there was a variance application related to off-street parking for the legalization of a second dwelling unit, though specific details of the outcome are not fully clear from the records provided.

Risk rating

How 527-529 26Th 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.
