Initial analysis

The property at 21-23 Crescent Avenue in Bernal Heights is a 2-story, 3-unit multi-family residential building constructed in 1907, currently owned by Aelj Revoc Trust. The building underwent significant renovations in 2008, including comprehensive updates to the top unit at 23 Crescent Avenue, featuring kitchen and bathroom remodeling, new heating system installation, and electrical upgrades. A notable sequence of events occurred in 2007-2009 involving multiple building complaints and violations related to unauthorized work on the rear cottage, including interior remodeling without proper permits, installation of new doors/windows, construction of stairs/landing, and issues with mold/mildew, heating system compliance, and lead paint concerns. These violations were ultimately resolved by July 2009.

More recent improvements were made in 2016, including a second-floor kitchen remodel and half-bath addition, along with plumbing and electrical upgrades. The property has experienced various maintenance issues in 2024, primarily related to sidewalk garbage and debris problems, though these external factors are not necessarily indicative of building condition or management quality. A cancelled permit application in 2016 (PP201602119342) aimed to clarify unit designations, attempting to establish the rear unit as legal non-conforming, while 21 and 23 Crescent Avenue remained as legal conforming units. The building's long history shows continuous maintenance and upgrading efforts, with most significant violations having been addressed through proper channels, though some work was performed without permits, prompting initial enforcement actions. The property's recent history (post-2016) has been relatively quiet in terms of major building code issues, with most recent attention focused on external maintenance matters.

Risk rating

How 21-23 Crescent 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.
