Initial analysis

The three-story multi-family residential building at 28 Day Street in Noe Valley, owned by Steve K Bak, has undergone significant recent developments and faced various maintenance challenges. Built in 1900, this flats & duplex structure is presently the subject of planning considerations for substantial redevelopment. Current planning records indicate two active applications under review for a proposed four-story reconfiguration, which would replace the existing structure containing three units (two authorized, one unauthorized) with substantially upgraded accommodations, though some previous applications related to this project have been cancelled.

The building and its surroundings have experienced several maintenance and compliance issues in recent years, particularly in 2023-2024. There have been multiple incidents involving waste management concerns, including several cases of garbage toter violations, with four reported instances between January and April 2023, and more recent street cleaning issues in May and August 2024. The property has also faced some safety concerns, including a protruding curb ramp issue reported in February 2024, a rat/insect infestation complaint in July 2024, and various street space maintenance matters (evidenced by sidewalk permits issued in 2008 and 2012). Notably, there have been three tenant buyouts recorded between 2022-2023, with compensation amounts ranging from $61,000 to $156,000, suggesting significant recent tenant turnover prior to the planned redevelopment. A plumbing upgrade was completed in 2012 involving the replacement of a sewer house trap, indicating some attention to infrastructure maintenance, though this is now quite dated relative to the building's current needs.

Risk rating

How 28-30 Day 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.

Neighborhood percentile
