Initial analysis

The two-unit residential building at 185-187 19th Avenue in the Lake-The Presidio neighborhood is a two-story flats and duplex structure built in 1924, currently owned by Kelly Marie O'Donnell since 2020. The property has undergone several significant changes and faced multiple regulatory challenges over recent years. Most notably, from 2017-2020, there were multiple complaints and enforcement actions regarding an unpermitted dwelling unit (UDU) and illegal short-term rentals, particularly concerning an unauthorized ground floor kitchen that was ultimately removed in 2021 through permitted work costing $7,000. The building has seen various improvements and maintenance work, including a bathroom renovation in late 2022 ($15,000), reroofing in 2021 ($10,500), and multiple plumbing and electrical upgrades.

Recent history shows the building has experienced some maintenance and infrastructure challenges, including two recorded sewage backup incidents in early 2023. The property has had recurring issues with driveway blocking, particularly in 2024, with multiple citations issued to offending vehicles. A tenant buyout was recorded in September 2017 for $51,375 involving three tenants. While many past complaints have been marked as "closed" or "abated," including those related to illegal short-term rentals and the UDU removal, the building has experienced ongoing parking enforcement issues and infrastructure maintenance needs, particularly regarding sewer systems as evidenced by the 2023 incidents. All major permit-related work, including the critical UDU removal and bathroom renovation, has been properly completed through official channels, suggesting improved compliance with building codes in recent years.

Risk rating

How 185-187 19Th 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

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
