Initial analysis

The property at 4186-4192 17th Street is a two-story multi-family residential building located in the Corona Heights neighborhood, containing four units and owned by the Achterkirchen Family Trust. Built in 1904, this TIC building has undergone several significant improvements over the past two decades. Most recently, in 2018, a bathroom remodel was completed including a stand-in shower and skylights, along with electrical panel relocation and bathroom wiring updates. In 2016-2018, there were multiple window replacement projects, including the installation of wood double-hung windows with improved energy efficiency features. The building underwent substantial electrical upgrades in 2006, including 200-amp service installation and subpanel additions, and kitchen and bathroom remodels were completed in multiple units during the same period.

The building has a history of addressing safety concerns, particularly regarding lead paint and fire hazards. A significant cluster of violations was recorded in 2001, involving lead paint hazards, fire egress issues, and structural concerns, though these were all abated by December 2003. A variance was approved in 2020 to legalize a deck and hot tub installation. More recently, there was a short-term rental violation investigated in 2019 regarding unit 4188, which was subsequently abated when the listing was removed. The property has undergone regular routine inspections by Housing Inspection Services in 2001, 2009, and 2010, with all cases being closed. The most recent activity outside the building's main operations includes several 311 calls in 2023-2024 regarding parking, graffiti, and street maintenance issues, none of which directly relate to building safety or habitability.

Risk rating

How 4186-4192 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.

Neighborhood percentile

Out of 348 buildings in this neighborhood, 282 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.

Neighborhood location

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 50.4%
Moderate concern 20.0%
Severe concern 29.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
