Initial analysis

The property at 3947 Cesar Chavez Street is a two-unit, two-story multi-family residential building located in Noe Valley, constructed in 1925 and classified as a flats and duplex structure. The building's recent maintenance history shows significant attention to basic upkeep, with completed work including a $10,500 re-roofing project in November 2024 and a substantial window replacement project in 2018 costing over $40,000, which upgraded all street-facing windows from various materials to wood-based composite Fibrex windows with double-hung functionality. However, the building has faced serious challenges with a pattern of maintenance violations documented in 2017, including problems with interior surfaces, sanitation (rodent infestation), security (rear door issues), and safety concerns (smoke and carbon monoxide detector requirements). These violations, along with three active task force inspections from August 2017, suggest significant habitability concerns during that period.

The property has experienced various maintenance and compliance issues between 2017-2023, including an active complaint filed in January 2017 regarding multiple interior problems (mold/mildew, damaged walls, floor covering issues) and exterior concerns (weather proofing on siding). The building's surroundings have been the subject of multiple 311 calls in recent years, with the most pressing current issue being an open sidewalk defect reported in November 2024. Additional concerns have included illegal vehicle parking on sidewalks, tree maintenance, and various general cleaning issues in the vicinity. While some of these external issues are being addressed through citations and service requests, they primarily relate to the building's environment rather than the structure itself. The most recent confirmed work on the building (the 2024 re-roofing project) indicates ongoing maintenance, though the presence of multiple active violations from 2017 suggests there may still be unresolved compliance matters requiring attention.

Risk rating

How 3947 Cesar Chavez 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.
