Initial analysis

The property at 3549 23rd Street in Noe Valley is a three-story, two-unit multi-family residential building constructed in 1900, currently owned by Khoury & Tanner Family Trust. The building has undergone several significant improvements over the past decade, most notably a comprehensive seismic retrofit and renovation in 2012 that included voluntary foundation replacement, unit relocation from the third floor to the first, deck modifications, and bathroom updates with a construction cost of $185,000. In 2013, the building received important safety upgrades including the installation of fire sprinklers on the second and third floors, full electrical rewiring, plumbing system improvements, and the installation of a combination fire service. More recent improvements include the addition of mini-split heat pump systems in 2018 (costing $13,000), and solar panel installation in 2017 (7.56 kW system with 24 PV modules).

The building has a history of addressing maintenance and safety issues, with the most significant past concerns occurring in February 2001 when multiple violations were recorded regarding water damage, mold/mildew, heating system adequacy, and smoke detectors. These violations were promptly addressed and abated by March 15, 2001. The property has maintained good compliance since then, with recent maintenance issues primarily related to street parking and sidewalk usage, as documented in 311 calls. The most recent building-related service requests have focused on exterior issues such as pavement defects and waste management, with all cases being resolved. The building's systems have been systematically updated over the years, including HVAC, electrical, and plumbing, suggesting a well-maintained property with modernized infrastructure.

Risk rating

How 3549 23Rd St'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.
