Initial analysis

The property at 539-541 24th Avenue in the Central Richmond neighborhood is a three-story multi-family residential building constructed in 1941, containing two units. The building underwent significant improvements in 2012-2014, including a substantial 12-foot horizontal addition and vertical extension, adding various living spaces such as an office, family room, five bedrooms, three storage rooms, laundry facilities, two study rooms, and three bathrooms, with a total construction cost of $150,000. This major renovation project included the installation of a fire sprinkler system for the new and ground floor areas, though it initially generated three building complaints in November 2013 regarding potential permit violations, which have since been marked as not active.

More recent improvements include a garage door replacement in 2022 costing $3,700, and in 2013, the property underwent extensive remodeling work including updates to two bathrooms and two kitchens with associated utility work, although these permits have since expired. The building has also seen various smaller improvements over the years, such as window replacements in 2002 (eight street-facing and four rear egress windows) and the addition of a half bathroom and family room conversion in the same year. Recent 311 calls related to the property have been minimal, with the most recent service request occurring in April 2024, though this was not specifically related to building conditions. The current ownership is listed as Lok Wayne & Lee Tracy M, and while there were multiple concerns regarding unauthorized construction work in 2013, all related building permits have been properly issued or completed, suggesting that these earlier issues were resolved through the normal permitting process.

Risk rating

How 539-541 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
