Initial analysis

The property at 4334-4336 17th Street is a two-unit, two-story multi-family residential building located in Corona Heights, constructed in 1908 and currently owned by Raymond D. Trew. The building has undergone several significant improvements and faced multiple compliance issues over the years. Most recently, in 2023, a bathroom remodeling project was completed, including changes to the bathtub, tile, faucet, sink, and cabinet, representing an investment of $25,000. Other recent improvements include reroofing work completed in 2020. A notable compliance issue occurred in 2016 when a storage shed constructed at the front of the property triggered violation proceedings, though this was resolved by May 2017. The building has also experienced periodic maintenance and upgrade work, including a significant bathroom remodel in 2010, conversion of a storage area to habitable space in 2011, and various plumbing and electrical upgrades.

The property has a history of addressing both routine maintenance and regulatory compliance matters, including the removal of an illegal kitchen and bathroom from a ground-level studio in 2005, which involved capping all utilities at the source. More recently, there have been ongoing concerns about waste management, with multiple 311 calls in 2023-2024 regarding waste receptacle placement. The building has also undergone various plumbing and electrical improvements over the years, including a 200-amp service upgrade in 2006 and compliance work following inspection reports. While there have been some complaints regarding building conditions, including mold issues (2016) and water accumulation in storage areas (2005), these have generally been addressed through proper channels. Recent 311 calls primarily relate to waste management concerns, though there have been some parking-related complaints in 2023. The property has been subject to regular building permits, plumbing permits, and electrical permits, indicating ongoing maintenance and improvement work.

Risk rating

How 4334-4336 17Th 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.

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.

Building age

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

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 86.6%
Moderate concern 9.3%
Severe concern 4.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
