Initial analysis

The three-story multi-family residential building at 234-236 Carl Street, currently owned by Matthew & Patricia Kruger, was constructed in 1900 and contains four units. The property has undergone several significant changes and maintenance activities over its lifetime, most notably in 1999 when a major renovation attempt was made to merge two units into one top-floor owner's unit (though this permit ultimately expired). In recent years, the building has seen improvements including the replacement of nine street-facing windows with double-hung wood-clad windows in 2017 (at a cost of $10,000). The building has experienced multiple routine housing inspections over the years, with the most significant cluster of violations occurring in 2001-2006, primarily related to fire safety and security issues such as fire extinguisher maintenance, deadlatch requirements, and fire escape maintenance, all of which were ultimately abated by August 2007.

The property has a notable history of compliance issues during the late 1990s, including concerns about illegal units and hazardous wiring in 1998-1999, as well as plumbing work conducted without proper permits. More recently, there was an investigation into illegal short-term rentals in 2018 that was addressed through a Notice of Violation. The building's maintenance history shows attention to basic upkeep, including reroofing in 1990 and stair repairs in 2002, though some permits from the early 2000s related to unit modifications are listed as expired. Property management has been active in addressing both routine maintenance and regulatory requirements, with recent 311 calls primarily related to parking violations rather than building-specific issues, suggesting improved overall building management in recent years.

Risk rating

How 234-236 Carl 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
28th percentile

Out of 526 buildings in this neighborhood, 379 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 58.2%
Moderate concern 17.3%
Severe concern 24.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
