Initial analysis

The property at 923 Minnesota Street is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Elizabeth A. and Marti Derenzy. The building has undergone significant improvements over the past decade, including substantial renovation work in 2018-2019 that involved a $115,000 kitchen and dining room remodel with new electrical, plumbing, windows, and flooring, along with foundation strengthening. Prior improvements included bathroom remodels on both floors (2011-2012), reroofing projects in 2014 and 2002, and repairs to front stair treads and floorboards in 2013. The building systems were updated with two furnace replacements in 2021, a sewer lateral repair in 2015, and various plumbing and electrical upgrades associated with the remodeling work.

Historical records show the legalization of the second dwelling unit in 1987, and a notable complaint in 2012 regarding heating issues, bathroom leaks, and moisture problems, though this complaint was promptly addressed within one day. Recent 311 calls from 2021-2024 have primarily concerned street maintenance issues outside the building, including reports of waste on sidewalks and other environmental concerns, with the most recent being a garbage and debris complaint in July 2024. Three work approvals were granted in 2022-2023 involving window changes in the lightwell area and dining room glazing improvements, as well as tandem parking legalization. The building's maintenance history suggests regular upkeep and substantial investment in improvements, with no active building code violations or serious maintenance issues currently on record.

Risk rating

How 923 Minnesota 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
93th percentile

Out of 74 buildings in this neighborhood, 5 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.

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 83.8%
Moderate concern 12.4%
Severe concern 3.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
