Initial analysis

The two-unit, two-story multi-family residential building at 1818 Green Street in Cow Hollow, owned by Leta Qw Ching Qualified Per, has undergone several significant renovations since its construction in 1900. The most substantial work occurred between 1998-1999, when horizontal and vertical additions were completed, followed by the merging of two units into one and the installation of a new second unit. Other notable improvements include garage modifications in 2001, a roof replacement in 2002, and foundation work in the garage area. More recently, in 2022-2023, there were approved plans to close existing rear yard stairways and third-floor roof deck, replace stairways with new fire escapes, update the rear roof to a flat design, and enlarge the garage entrance, indicating ongoing commitment to maintaining and upgrading the property.

The property has experienced regular maintenance and cleaning needs in the surrounding area, with multiple reports of loose garbage requiring attention between 2022-2024, including incidents involving human or animal waste in 2023. Most recently, there have been several parking-related issues in early 2024, including blocked driveways and illegal parking. These external matters, while not directly related to the building's condition, may impact resident experience. The building's permit history and planning records suggest a well-maintained property undergoing appropriate updates, with the most recent major modifications focusing on safety improvements and structural updates.

Risk rating

How 1818 Green 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.
