Initial analysis

The property at 46-48 Sumner Street is a two-story, multi-family residential building constructed in 1906, containing two units and currently owned by Ryan Meinzer. The building has undergone substantial renovations and improvements over recent years, most notably in 2018-2020, when extensive window replacements were completed (with both wooden and vinyl frames), followed by comprehensive kitchen and bathroom remodels in addition to HVAC system enhancements. The property has also complied with an important 2021 physical inspection report (CC-8346), which included necessary plumbing and electrical updates. Historical issues from 2015-2016 regarding window maintenance, general dilapidation, and various maintenance concerns were all resolved, and there was one tenant buyout recorded in January 2016 for $22,500 involving one tenant.

The building's maintenance history shows attention to both structural and cosmetic improvements, with significant investments in plumbing and electrical systems, including complete rewiring in 2018 and bathroom/kitchen upgrades in 2016-2018. While there have been multiple 311 reports in 2024 regarding street conditions near the property, these are primarily related to sidewalk cleaning and maintenance issues rather than building-specific concerns. A notable infrastructure upgrade occurred in 2018 with the installation of new bathroom facilities and kitchen remodeling work. The building also underwent a formal condominium conversion process in 2021, which included necessary infrastructure upgrades to meet current standards. The most recent improvement, completed in April 2024, involved the replacement of a backyard window, continuing the building's pattern of regular maintenance and upgrades.

Risk rating

How 46-48 Sumner 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
