Initial analysis

The three-unit, three-story multi-family residential building at 877-881 Valencia Street in the Inner Mission, owned by Wilfried R R Wietstock, has experienced several significant maintenance and repair events since its construction in 1909. Most notably, in 2023, complaints were filed regarding rotted window frames, while previous violations in 2005 highlighted multiple issues including problems with stairs, floor coverings, plumbing fixtures, handrails, window components, interior surfaces, heating systems, and lack of smoke detectors - all of which were abated by December 2005. The building underwent several substantial improvements in the past decade, including window replacements in 2018, a historic roof replacement in 2014, and extensive shoring and underpinning work in 2013 related to nearby construction at 899 Valencia Street, which was valued at over $51,000.

The property has required ongoing maintenance work, with multiple roofing projects documented in 2005, the addition of an awning in 2001, and staircase repairs following housing inspector recommendations in 2005. More recently, between 2024 and 2025, there have been recurring issues with graffiti and debris on and around the property, as evidenced by multiple 311 calls for graffiti removal and street cleaning. The building’s current condition is of particular concern, with active infrastructure issues noted in the 2023 complaint about window frames. While many past violations have been addressed, the frequency of recent graffiti incidents and cleanliness issues suggests ongoing challenges with property maintenance in the immediate vicinity.

Risk rating

How 877-881 Valencia 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.

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
