Initial analysis

The property at 231-233 24th Avenue is a two-unit, two-story multi-family residential building constructed in 1916, currently owned by Matthew T. and Emily R. Walsh. The building has undergone significant renovations and improvements over the past decade, with the most substantial work occurring between 2015-2020. Completed improvements include comprehensive remodels of both units featuring kitchen and bathroom renovations, installation of a hydronic radiant heating system with combi boilers, and a full electrical upgrade. Major structural modifications were attempted, including a cancelled 2020 permit for a fourth-floor addition and rooftop deck, which was initially valued at $480,000. The building has been maintained with current plumbing upgrades including new water heater flues and additional bathroom facilities.

The property has one notable building complaint from 1994 regarding plumbing issues and possible illegal units, which remains listed as active but not necessarily as a current resident concern. Recent activity at the property has primarily consisted of routine street maintenance issues, with several 311 calls in 2023-2024 related to garbage and debris on the street, though these do not directly reflect on the building's condition or management. The most recent permit filed (2022) indicates smaller-scale improvements including foundation work and pantry modifications. While substantial upgrades have been completed throughout the building, recent permits suggest a transition to smaller-scale improvements compared to the major renovations of 2015-2020.

Risk rating

How 231-233 24Th Ave'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.

Neighborhood percentile
