Initial analysis

The two-unit residential building at 665 Connecticut Street in Potrero Hill, owned by Schlarmann Reinhold F 1993, has undergone several significant maintenance and upgrading work projects in recent years. Most notably, in late 2023, the property received substantial infrastructural improvements including the installation of two new gas water heaters (completed December 2023), two new furnaces with associated ductwork (completed August 2023), and a reroofing project along with non-structural deck repairs (issued August 2023 with a cost of $10,000). These recent updates suggest proactive maintenance of the property's systems and structure.

The building's maintenance history includes some past repairs, such as dry rot remediation work completed in 1996 involving beams in the sub-area, upper decks, and rear property. The property has had minimal major incidents affecting resident safety or comfort, with the most recent 311 call being noise-related (August 2024, currently open) and a Rent Board customer callback related to housing inventory matters (October 2023, resolved). While there have been some neighborhood issues recorded through 311 calls (including parking violations and street maintenance matters) between 2012-2019, these were external to the building and primarily related to street-level concerns such as abandoned vehicles, burnt-out streetlights, and missed street cleaning routes. The building's documented history indicates regular maintenance and upgrading of essential systems, particularly in 2023, with no recorded history of serious maintenance issues or safety concerns in recent years.

Risk rating

How 665 Connecticut 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.
