This building has 20 novs (7y), above the Mission Bay average of 10.2.

This building's 87% risk is high in absolute terms; it still rates lower-risk here because buildings in Mission Bay generally score worse. The colour is relative to the neighborhood, the percentage is not.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Initial analysis

The multi-family residential building at 1101-1135 4th Street in Mission Bay, currently owned by Dco Mission Bay Lp, has experienced several significant maintenance and compliance issues over the past two years. Most pressing were multiple violations in late 2023 related to unauthorized boiler operations, with three separate units cited between September and December 2023 (serial numbers 1702438241, 2206545025, and 2206545029). These violations were resolved by October 2024. In early 2024, the property implemented plans for electric vehicle charging infrastructure, including the installation of five dual-port charging stations, with work beginning in April 2024.

The building has faced recurring mechanical systems challenges, including a malfunctioning elevator system that reportedly affected access for disabled residents in late 2022 and continued into 2023, though this issue was documented as resolved by February 2023. More recently, in October 2023, bathroom ventilation problems were reported, indicating potential mold/mildew concerns due to non-functioning mechanical ventilation systems. Of particular concern is a recent complaint from August 2024 regarding unannounced fire alarm testing that occurred over extended periods, leading to resident concerns about communication and safety. The building's maintenance history suggests ongoing challenges with timely permit renewals and mechanical system reliability, though most cited violations have been addressed, with the exception of the recent fire alarm communication issue which remains unresolved as of August 2024.

Risk rating

How 1101-1135 4Th 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
55thpercentile

Out of 20 buildings in this neighborhood, 9 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
