Initial analysis

The four-unit, four-story multi-family residential building at 35-39 Ramona Avenue in Mission Dolores, owned by Robert & Patricia J Koren R, was constructed in 1912 and has undergone several significant modifications in recent years. Between 2015 and 2016, the property underwent a major renovation project to legalize an unauthorized ground floor unit (39A), which included the installation of a new studio, structural improvements, and comprehensive updates to plumbing, electrical systems, and fire safety features including a partial fire sprinkler system. This project also involved substantial improvements to the building's infrastructure, including kitchen remodels, bathroom renovations, electrical service upgrades to 200 amps with five meters, and the installation of a new retaining wall. The building's safety systems were addressed through the installation of fire sprinklers and modernization of fire safety features.

Historical records show that in 2004, the building was cited for several safety violations related to exterior stairs and handrails, as well as fire extinguisher maintenance, though all these violations were abated by December 21, 2004. More recent history includes two routine safety inspections in 2008 and 2021, with no active violations noted. The property has had minimal complaints in the last several years, primarily consisting of two noise complaints in January 2019 and several reports of abandoned vehicles near the property in 2021. The 2015-2016 renovation period was marked by significant investment in property improvements, totaling over $200,000, with multiple building, plumbing, and electrical permits issued and completed, suggesting a proactive approach to maintaining and upgrading the property's systems and compliance with current regulations.

Risk rating

How 35-39 Ramona 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.
