Initial analysis

The property at 3526-3528 24th Street is a two-unit, two-story multi-family residential building located in Noe Valley, built in 1900 and currently owned by Wu Mo Alberto. The building is undergoing significant renovations, with the most recent permit filed in December 2022 for a substantial 799-square-foot rear addition across multiple levels, including new bedrooms, bathrooms, and a family room. This work follows a previous major renovation in 2020 that involved excavating the basement to create additional living space for unit #1, along with adding new interior connections and utility infrastructure. The building's electrical system was modernized in 2004 with the conversion from overhead to underground service and the installation of three new meters.

The property has experienced several maintenance and infrastructure challenges in recent years, most notably a series of sewer issues in early 2020, with three separate sewage backup incidents reported within a month. More recently, in December 2023, there were reports of water leaks. The building also faced some compliance issues, with a complaint in March 2023 regarding an illegal tent structure in the backyard, though this was promptly abated within one day. Historical records show an infrastructure upgrade in 2004 with the installation of new electrical service, and a 2019 incident involving graffiti on the sidewalk that was addressed by the owner. The property has undergone various modifications aimed at improving living conditions and adding space, with planning records indicating careful consideration of maintaining the building's existing unit configuration while expanding its footprint.

Risk rating

How 3526-3528 24Th 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.
