Initial analysis

The property at 255-257 26th Ave is a two-story, three-unit multi-family residential building located in the Lake - The Presidio neighborhood, owned by David K & Nisa M Ching Revo and constructed in 1984. The building has experienced several significant maintenance and safety-related events over its history, with the most concerning being a report of an "unstable deck in back" filed in June 1999, which was quickly addressed within a day. In August 2003, repairs were completed on the rear stairs connecting to the deck, involving replacement with treated wood or redwood at a cost of $500. More recently, in February 2023, there was a general hazardous materials complaint that was found to have "No Merit." The building has had three fire alarm system incidents between 2010-2011, though all were resolved with "Condition Corrected" status, and one carbon monoxide detector activation with no CO detected.

The property has experienced ongoing maintenance issues with overgrown trees in the vicinity, with multiple pruning requests filed between July and September 2023. The most recent tree maintenance was completed in October 2023 as part of the Block schedule. The building's immediate vicinity has been the subject of frequent parking enforcement activity, particularly regarding blocked driveways, with multiple citations issued between September 2024 and November 2023. The area has also seen some irregularities with double parking and blocked driveway incidents, though some cases were marked as "Invalid" due to insufficient reporting information. While these parking issues and tree maintenance needs are notable, they primarily affect the external environment rather than the building's internal systems or resident safety.

Risk rating

How 255-257 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.
