Initial analysis

The two-unit residential building at 4069 23rd Street in Noe Valley is a 2-story flats and duplex structure built in 1900, currently owned by the Staley Family Revocable Intangible Trust. The property has undergone several significant improvements over the years, with the most recent major work including a 2017 furnace reinstallation and a 2014 sump drain connection to the existing sewer system, both of which were completed successfully. Substantial renovations occurred in 2007-2008, encompassing comprehensive bathroom remodeling ($85,000), including master and guest bathroom updates, closet reconfigurations, and the addition of a laundry closet, along with associated electrical and plumbing work. The building has maintained its structural integrity through various upgrades, including termite repair in 1992 and historical improvements such as a horizontal extension with balcony addition in 1987 and deck construction in 1984 (with a subsequent successful permit in 1985).

The property has experienced occasional neighborhood issues, as evidenced by multiple 311 calls regarding abandoned vehicles between 2010 and 2021, though these were external matters not directly related to the building's condition. Other neighborhood incidents, including illegal postings and encampment items (both in 2014), were promptly addressed by city services and do not reflect on the building's maintenance or safety. The comprehensive permit history demonstrates regular maintenance and upgrading of the property, with particular attention paid to modernizing essential systems such as plumbing, electrical, and HVAC components, ensuring that the building remains in good working order while preserving its historic character.

Risk rating

How 4069 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.
