Initial analysis

The three-story, 15-unit apartment building at 420 7th Ave in the Inner Richmond, built in 1964, has undergone several significant safety improvements over the years. Most notably, the building completed a mandatory soft-story retrofit in 2016 (cost: $25,000) to improve seismic safety, and is currently in the process of upgrading its fire alarm system as of February 2024 to comply with the latest codes, including the installation of new monitoring equipment, smoke detectors, and horn/strobes in common areas. The building has had recurring fire safety concerns, with violations related to blocked exits, alarm systems, and fire escapes recorded in 2023, 2016, and 2009, though all these issues were subsequently corrected. Historical records show the building has addressed various maintenance needs, including window replacement in 2004 ($54,000), flue repairs in 2015 ($5,000), and re-roofing work completed in 1989.

The property has been subject to multiple routine housing inspections over the years (most recently in 2015), during which various violations were documented and subsequently resolved. These included issues with egress, smoke enclosure doors, fire system maintenance, and other safety concerns. While all these violations were abated, some had a notable number of associated complaints, particularly in 2004 when multiple fire safety violations were documented. Recent years have shown ongoing attention to building safety systems, with the installation of smoke enclosure door closers and improvements to fire alarm systems. The building's immediate surroundings have experienced typical urban issues as documented in 311 calls, including various street cleaning and maintenance matters, though these are not directly related to the building's condition or safety systems.

Risk rating

How 420 7Th 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.

Building size

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

Number of units

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

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 33.2%
Moderate concern 47.4%
Severe concern 19.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
