Initial analysis

The property at 4122-4124 17th Street in Corona Heights is a two-unit, two-story residential building constructed in 1907, currently owned by Mikhail Maksin and Verba Viol. The building has undergone several proposed modifications over the past several years, with the most significant being a filed permit in March 2022 seeking to expand the structure to four stories with three units and a new garage, though previous attempts to add an underground garage in 2017 were withdrawn. The building is currently facing multiple active violations filed in April 2024, including issues with damaged ceilings, plumbing problems (including bathtub and water pressure issues), electrical concerns (including unapproved wiring), and safety deficiencies (including broken steps and handrails). These violations are set for a director's hearing on December 19, 2024.

Recent inspection complaints from 2024 highlighted significant maintenance problems, including plumbing inoperability, water leaks, ceiling damage, drainage issues, and pest concerns. Electrical issues were also documented in July 2024, and there was a serious plumbing complaint in March 2024 involving leaks, structural concerns, and problems with the bathtub drainage system. Historical records show some maintenance work was completed in 1992 with a reroofing project, and electrical improvements were discussed in early 2017, though a violation notice was issued in April 2024 regarding electrical modifications requiring new permits. The property has also experienced some external issues, as evidenced by 311 calls regarding toters being left out (2023), sidewalk blockage (2016), and a temporary encampment nearby (2023).

Risk rating

How 4122-4124 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.
