Initial analysis

The property at 1697-1699 23rd Avenue in the Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1927, currently owned by Jason Martinez and Linh Ly. The building has undergone several significant maintenance and improvement projects over the years, including window replacements (2004), kitchen renovations (2010), roofing work (2008), and more recent plumbing work including a gas line extension (2018). However, the property has also experienced multiple issues that may impact resident quality of life. A notable series of complaints and violations in 2010 involved unauthorized kitchen demolition work, including the removal of sinks, cabinets, and flooring, which led to a notice of violation that was eventually resolved through permitted repairs. More recently, in April 2019, there were complaints regarding work without permits, including mold remediation, dry rot issues, and exterior stucco problems.

The building's recent history shows some maintenance challenges, with a sewage backup incident reported in December 2024 and multiple complaints about garbage and debris in November 2024. The property has gone through several tenant buyouts between 2019 and 2024, with the most recent one at 1690 24th Avenue in May 2024 involving a compensation amount of $125,000 for one tenant. While the building has received attention through various permits and repairs over the years, including electrical and plumbing improvements, the frequency of complaints and code violations in past years suggests a pattern of maintenance issues that have required corrective actions. The most recent tenant buyout activity and the age of the building (over 95 years old) indicate ongoing changes to the property's occupancy and potentially its maintenance requirements.

Risk rating

How 1697-1699 23Rd 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.
