Initial analysis

The three-story, six-unit multi-family residential building at 1240-1244 South Van Ness Avenue in the Inner Mission, built in 1909, has undergone several significant maintenance and compliance events over the past few decades. Most recently, the building received a new roof in September 2024 at a cost of $18,000, marking the first substantial roofing work since a 1997 permit. In April 2016, the electrical system was notably upgraded with a new 200-amp service and individual meters for each unit, demonstrating investment in infrastructure. A routine housing inspection in March 2023 revealed several compliance issues that were promptly addressed within a week, including requirements for fire safety documentation, fire extinguishers, storage practices, and various interior maintenance matters. This followed a history of compliance monitoring through routine inspections in 2015, 2009, and 2007.

The building's maintenance history shows attention to critical systems, with records indicating previous corrections of alarm system issues in 2013 and a range of other fire safety concerns in 2009, all of which were resolved promptly. Historical complaints from 1994 noted various unit conditions including flooring and plumbing concerns, which appear to have been addressed. Recent service calls in late 2024 included one report of sewage discharge from a vent, which was resolved by field operations. There have been multiple parking-related complaints in 2024, primarily regarding driveway blocking, suggesting ongoing issues with street parking management near the property. The building's fire safety systems have undergone periodic inspections and corrections, with no serious fire incidents recorded, though there were minor water-related and false alarm responses from the fire department.

Risk rating

How 1240-1244 South Van Ness 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
