Initial analysis

The building at 670 Valencia Street in the Mission Dolores neighborhood, owned by Mission Housing Development, appears to be a well-maintained multi-family residential property with a history of appropriate safety upgrades and maintenance. Originally constructed between 1995-1998, the property was developed as a four-story building with 28 units (construction cost of $3.25 million) and later received permits for additional work including fire sprinkler and alarm system installations, both of which were successfully completed. The building has undergone several important infrastructure updates over the years, including the replacement of defective backflow devices in 2019, domestic hot water boiler replacements in 2015, and a fire alarm system complaint that was promptly corrected within a day in December 2014.

The property has maintained regular inspections by Housing Inspection Services, with documented routine apartment house inspections in 2002, 2011 (no violations found), and a complaint regarding a non-functional intercom system in early 2013 that was resolved within a week. While there was an electrical permit application in 2007 for extensive lighting and electrical work, this permit was cancelled and no further documentation of this work is available. Overall, the building's maintenance record shows prompt attention to infrastructure issues and compliance with safety requirements, with most recent documented work focusing on plumbing system updates and safety systems maintenance.

Risk rating

How 670 Valencia St'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
93th percentile

Out of 799 buildings in this neighborhood, 56 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 age

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

Property class (A15)

The assessor's property-class code, which correlates with building type and the violation rates the model expects.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 81.9%
Moderate concern 12.3%
Severe concern 5.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
