Initial analysis

The property at 511 Crescent Avenue is a two-unit, two-story multi-family residential building located in Bernal Heights, constructed in 1907 and currently owned by the Ahmad Nasser 2015 Trust. Significant improvements have been made to the property over the past two decades, most notably in 2012 when a ground floor store was converted into habitable space, adding two bedrooms and a family room, along with associated electrical and plumbing work totaling approximately $34,500. Earlier renovations include a complete rewiring of the second floor in 2004 ($25,000), installation of mesh wire and stucco on two street-side walls in 2001 ($5,000), and reroofing in 1996. A key infrastructure upgrade was completed in 2009 with the installation of a new gas line.

The building has experienced minimal safety issues, with three fire complaints filed in 2006-2007 regarding combustible materials, grass/weeds, and an unspecified issue, all of which were determined to have "No Merit." A historical complaint from 1996 regarding water usage charges between residential and commercial units was promptly addressed within one week. The property has been subject to numerous parking-related incidents in recent months (2024-2025), with several reports of abandoned vehicles and driveway blocking, though most were resolved without enforcement action. Recent street cleaning issues were documented in late 2024, including reports of abandoned electronics and a mattress, both of which were resolved. A planning record from 1970 related to the property's status was approved and closed, though specific details are not provided in the available data.

Risk rating

How 511 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.

Neighborhood percentile
