Initial analysis

The two-story multi-family residential building at 4041-4043 23rd Street in Noe Valley, owned by Jared Britton and Mar Cerruto, was constructed in 1906 and contains three units. The building has undergone significant renovations and improvements over the past decade, with comprehensive work completed in 2013 including a kitchen and bathroom remodel, electrical upgrades, and the addition of a second bathroom costing $91,000. Subsequent improvements include roof replacement in 2020 ($13,000), soundproofing and interior work in 2019 ($11,500), and bathroom renovations in 2021. A major dry rot repair of the stairway and deck was carried out in 2016 at a cost of $30,000, following a repair notice issued in February 2016. Recent work includes a kitchen range hood replacement in November 2023 and lightwell sewer work in October 2023.

The building has had several routine inspections and some areas of concern over the years. In 2023, there were complaints regarding construction work and lead paint concerns, along with reported issues of major plaster cracking possibly related to foundation settling. Historical violations dating back to 2002 included problems with fire proofing, egress obstruction, and stairs, while 2023 inspections noted hazardous wiring and damaged interior surfaces that required attention to lead paint concerns. The property has also experienced some maintenance issues, including unpermitted construction work in 2016 and 2019, though most recent building permits indicate ongoing maintenance and improvements. The building's common areas and systems have been regularly updated, including a furnace replacement in 2014 and various electrical system upgrades. Compliance with safety and building codes appears to be maintained, with recent permits showing attention to both routine maintenance and system upgrades.

Risk rating

How 4041-4043 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

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.
