Initial analysis

The two-story, three-unit multi-family residential building at 490-494 Lisbon Street in the Excelsior neighborhood, currently owned by the Ming Fai Kwan Trust, was constructed in 1938 and has experienced several significant maintenance issues over the past few years. Most recently, in July 2023, there were major tenant complaints regarding no heat, water leakage near the kitchen, mold, and pest infestation, followed by additional issues of water damage and a broken window in August 2023. These problems were officially addressed through building permit #202308144328, which involved repairs to heating and water systems, bathroom fixtures, and drainage. The building has a history of maintenance and safety concerns, including a set of violations in 2007 related to lead paint hazards, stair repairs, fire safety, and egress obstruction, though these were all abated by January 2008. Earlier work included various improvements such as a 2014 renovation of bathroom and kitchen fixtures, a 2011 repair of dry rot in back stairs, and multiple window and bathroom repairs from 2009 to 2010, indicating ongoing efforts to maintain the property.

The building's maintenance history shows a pattern of periodic repairs and inspections, with several routine inspections revealing various issues that required attention. Notable past violations included concerns about stairs, fire safety equipment, and lead paint hazards in 2007, all of which were resolved by early 2008. The property has undergone multiple renovations over the years, including a significant 2014 kitchen and bathroom remodel costing $9,000. More recent complaints from 2023 indicate recurring issues with building systems, though these latest problems were addressed through proper permitting and repairs. The surrounding area has experienced various municipal service calls, primarily related to street cleaning and parking enforcement, with the most recent concerns being addressed in late 2024.

Risk rating

How 490-494 Lisbon 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.
