Initial analysis

The three-unit residential building at 1255 24th Avenue in San Francisco's Central Sunset neighborhood, owned by Ly Mymy, was constructed in 1957 and is classified as a two-story flats and duplex structure. The property has undergone several significant improvements over the years, with the most substantial renovation occurring in 2008-2009, which included comprehensive updates to all three units comprising kitchen and bathroom remodels, window replacements, and complete electrical rewiring with new service panels, along with the installation of modern appliances and smoke detectors. More recently, in 2016, the building underwent voluntary seismic strengthening work, including the addition of new shear walls and foundation improvements to enhance structural safety. The building's maintenance history shows attention to fundamental systems, with multiple roofing projects documented in 1995, 1997, and 2016, along with HVAC upgrades including furnace replacements and duct work.

The property has experienced some compliance and safety-related issues, particularly in July 2012 when there were reports of blocked exit common areas and unauthorized construction work, though these matters were subsequently resolved through inspections and violations. More recent concerns have primarily related to noise disturbances, with multiple reports filed between 2021 and 2024, though all were processed as informational reports or invalid cases. The building's maintenance record shows regular inspections and prompt attention to structural and safety improvements, including a complete plumbing system overhaul in 2008-2009. Recent 311 calls from 2021-2024 have primarily concerned general maintenance issues such as sidewalk cleaning and waste management, though these do not appear to represent any significant concerns about the building's overall condition.

Risk rating

How 1255 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.
