Initial analysis

The property at 1134-1136 Treat Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, built in 1900 and currently owned by Joseph T. Vargo. The building has undergone several significant infrastructure improvements over the years, including two main sewer line replacements in 2015 and 2011, which involved replacing 20 feet of clay sewer line with cast iron and installing a new house trap. In 2005, dryrot repairs were completed on the front stairs, including treads, risers, and handrails. The building faced multiple housing code violations in 2005, including issues with garbage storage, pest infestations, heating problems, plumbing repairs, and handrail requirements, though these were marked as "Not Active" and "Not Abated" according to records. Several historically significant repair and renovation projects were documented in the early 1990s, including bathroom remodeling, laundry room renovations, and foundation work.

More recent concerns have centered around parking issues, with multiple complaints filed in 2024 regarding blocked driveways, eight of which resulted in citations being issued. A complaint filed in October 2015 alleged unauthorized business operation in the garage, though this matter was marked as "Not Active." The building's documented history shows periods of maintenance and compliance improvements, particularly regarding plumbing infrastructure, while also revealing recurring issues with waste management, heating systems, and structural elements such as stairs and handrails. The property has also experienced some tenant-related concerns over the years, including a 1997 complaint about bathroom access and unauthorized unit conversion, though these issues appear to have been resolved.

Risk rating

How 1134-1136 Treat Ave'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

Out of 2380 buildings in this neighborhood, 238 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 78.3%
Moderate concern 12.8%
Severe concern 8.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
