Initial analysis

The two-story, four-unit multi-family residential building at 427 8th Avenue in the Inner Richmond, owned by Hallford Separate Property Trust, has undergone significant improvements and renovations in recent years. Most notably, the property has received substantial fire safety upgrades, including the installation of a comprehensive fire sprinkler system throughout the first floor and partial second floor in 2022 (completed at a cost of $29,138), followed by a new sprinkler monitoring system installation in early 2024 ($14,525). The building has also seen significant modernization efforts, including the 2021 conversion of storage and garage space into expanded habitable space for Unit #2, increasing its size from 846 to 1,751 square feet, and a 2022 upgrade to both electrical and HVAC systems, with the installation of a new 400-amp electrical service and mini-split heat pump system.

The property has a history of water-related issues, particularly evident in 2005 when complaints were filed regarding mold, standing water, and drainage problems, though these were all resolved promptly by August 2005. Recent maintenance activities have included siding replacement on the south side of the building in 2023 and plumbing upgrades such as a water heater replacement in 2022. The building's infrastructure has been significantly improved, with a complete electrical rewiring of Unit #2 in 2022, and the sewer line from foundation to curb was replaced in 2010. Recent 311 calls primarily relate to external issues such as parking violations and street maintenance, with one report in 2024 regarding tree root damage to the sidewalk still showing as open.

Risk rating

How 427 8Th 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
55th percentile

Out of 1723 buildings in this neighborhood, 775 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.

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.

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 78.8%
Moderate concern 10.1%
Severe concern 11.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
