Initial analysis

The two-unit, two-story multi-family residential building at 217 6th Avenue in San Francisco's Inner Richmond district has undergone significant renovations since its construction in 1900, with the most recent work being a reroofing project completed in August 2024 at a cost of $18,750. Major improvements were made between 2015 and 2018, including a kitchen remodel in 2015 to address a complaint about unpermitted construction work, followed by comprehensive interior upgrades in 2018 that involved replacing carpet with hardwood floors in bedrooms, updating the kitchen flooring, and renovating bathroom fixtures and tiles. The building has seen substantial modernization efforts between 2006 and 2007, including electrical rewiring of multiple rooms, bathroom and kitchen remodels, installation of double-glazed vinyl windows, and replacement of essential systems like the water heater and furnace. An infill lightwell project was completed in 2015, and in 2023-2024, additional improvements included window replacements in non-street-visible areas and other preservation work.

The property's maintenance record shows regular upkeep of critical systems and infrastructure, with attention to both interior and exterior elements. While there was one building complaint filed in 2015 regarding unpermitted construction work on the second floor, this was subsequently addressed through proper permitting and completion of the work. The surrounding area has experienced typical urban maintenance issues as documented in 311 calls, including reports of waste, pavement defects, and hazardous materials, though these were all street-related matters and not directly associated with the building itself. The property's long history of permitted improvements and systematic upgrades suggests ongoing commitment to maintaining and modernizing the building, with no documented safety concerns or persistent maintenance issues.

Risk rating

How 217 6Th Ave'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

Out of 1723 buildings in this neighborhood, 396 are predicted to be safer.
