Initial analysis

The 3533-3535 23rd Street property is a two-story multi-family residential building located in Noe Valley, containing three units and owned by Antonio Mezquiriz. Built in 1900, this flats and duplex-style building has undergone several significant repairs and improvements over the past two decades. Most recently, in August 2024, electric vehicle chargers were installed for unit 2 and unit 4, demonstrating modernization efforts by the current ownership. The building's history shows a pattern of maintenance and compliance work, particularly in the early 2000s, when multiple permits were issued and violations addressed, including kitchen remodeling in 2001, window repairs in 2006, and significant work in response to a 2001 routine apartment house inspection that identified multiple issues such as deteriorated drainage pipes, stair repairs, and safety concerns. These violations were ultimately resolved by November 2004.

The property has had several permitted construction projects, including kitchen remodeling in 2001 (though multiple permits for this work expired), stair repairs in 2002 (which generated a notice of violation), and window casing repairs in 2006. The building's maintenance record shows attention to both code compliance and modernization, as evidenced by the recent EV charger installation. The surrounding area has experienced typical urban issues as documented in 311 calls, though these are not directly related to the building's condition or management. Recent municipal services have responded to various sidewalk and street maintenance issues near the property, including a 2023 pavement defect report and parking concerns, but these external matters do not reflect on the building's internal conditions or management.

Risk rating

How 3533-3535 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.
