Initial analysis

The property at 631-635 6th Avenue in San Francisco's Inner Richmond neighborhood is a 3-story, 3-unit multi-family residential building constructed in 1915, currently owned by Taft Bradford J & Bonnie. The building underwent significant renovations in 2016, including comprehensive remodels of the upper and lower units (633 & 635), with updates to electrical, plumbing, and mechanical systems, window replacements, and garage modifications, costing approximately $290,000. A notable deck expansion project valued at $17,700 is currently permitted for 2024, involving the installation of a new fire-rated wall and outdoor GFCI receptacles. The building has seen major infrastructure improvements including the installation of radiant heat throughout three floors (2016), a new 200-amp main service (2016), and various plumbing upgrades.

The property has a history of violations and complaints dating back to 1996, including concerns about illegal units, unauthorized modifications, and fire safety issues. However, these historical violations appear to have been resolved, with most being abated by 2009-2015. The most recent building-related complaint was filed in 2020 regarding a greasy boiler room filter. The building underwent routine housing inspections in 2015 and 2017 with no major issues noted. Recent activity around the property has primarily involved parking violations, with multiple citations issued between 2023-2025 for sidewalk parking and driveway blocking, suggesting potential ongoing challenges with on-street parking management in the area. The property has also experienced periodic issues with debris and waste management as evidenced by 311 calls in recent months, though these were primarily related to street cleaning rather than building maintenance.

Risk rating

How 631-635 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, 1551 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

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

12-Month severity forecast
No violation 52.5%
Moderate concern 36.9%
Severe concern 10.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
