Initial analysis

The six-unit multi-family residential building at 600 9th Avenue in the Inner Richmond, owned by the Alice J Swanson Living Trust, was constructed in 1911 and has undergone several significant updates and maintenance activities over the past decades. Most recently, in November 2024, the building completed a domestic hot water and storage tank replacement. The property has faced multiple safety compliance issues, most notably in 2017 when an annual routine inspection revealed several violations including the need for fire door closers, carbon monoxide detectors, and stair repairs, all of which were addressed by August 2017. Previous major maintenance included a complete re-roofing project in 2016 costing $47,700, though an earlier roofing permit from 1994 had expired.

The building has experienced some infrastructure challenges in recent years, with 311 calls in 2024 reporting a sewage backup from the side sewer vent and multiple parking-related issues. There is also ongoing attention required for fire safety systems; a 2021 permit application for a new fire alarm system was cancelled. The property's maintenance history shows regular oversight and response to violations, with the owner addressing the 2017 complaints through necessary repairs, including the reparation of less than 50% of stairs at the back of the property costing $1,400. The building's safety record includes two fire department responses for smoke detector activation and a false alarm, neither resulting in injuries or indication of actual fires.

Risk rating

How 600 9Th 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

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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 66.6%
Moderate concern 20.2%
Severe concern 13.3%
