Initial analysis

The property at 1435-1437 6th Avenue is a two-story, multi-family residential building constructed in 1919 in San Francisco's Inner Sunset neighborhood. The building, which is classified as a Flats & Duplex structure, contains three units and is currently owned by the Helen Y L Fong Survivors Trust. The building's maintenance history shows several notable events: in 2005, there were both permits and a building violation related to repairs needed for rear stairs and decks, which were completed by September 2005 at a cost of $3,500. Routine housing inspections were conducted in 2000, 2005, and 2010, all of which were marked as not active following their resolution.

More recent activity around the property has primarily involved infrastructure issues affecting the surrounding area, with multiple 311 calls in late 2024 regarding pavement defects on nearby sidewalks and curbs, all of which were resolved. Throughout 2023, there were several reports of bicycle lane blockages and issues with animal noise (specifically barking dogs) near the property, though these were external matters. The building's documented history shows regular maintenance of critical structures like stairs and decks, with no significant building violations or safety concerns recorded in recent years. The most recent documented maintenance work on the property was completed nearly two decades ago, with no major structural issues reported since.

Risk rating

How 1435-1437 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
34th percentile

Out of 1493 buildings in this neighborhood, 985 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 57.7%
Moderate concern 28.3%
Severe concern 13.9%
