Initial analysis

The 12-unit apartment building at 670 Monterey Boulevard, owned by Miguel F & Joanne P Navarro, is a three-story structure built in 1964 and currently undergoing a significant $125,000 soft-story retrofit to improve seismic safety, with the permit issued in August 2023. The building has experienced several major maintenance and safety events over the years, most notably a fire incident in 2011 that required substantial repairs to Unit 6, including kitchen replacement, electrical upgrades, and plumbing work totaling $42,000. Three fire safety complaints regarding blocked exits and fire escape concerns were filed in 2019 and 2023, though all were marked as "Condition Corrected." The building faced serious habitability issues in February 2010, when multiple violations were documented, including inadequate heating, electrical problems, plumbing issues, and various interior surface problems, though these violations were all abated by May 2010.

The property's recent maintenance history shows attention to building upkeep, including a reroofing project completed in 2020 ($22,000). Regular inspections have been conducted, with recurring issues related to tree maintenance and street lighting being reported in 2024. Of particular note is the presence of multiple fire safety concerns over the years, including alarm system issues (2015, 2016, 2017), though these were generally addressed promptly. The building has undergone routine inspections and periodic maintenance work, with the most recent significant safety upgrade being the ongoing soft-story retrofit. The property has also been the site of some tenant distress moments, as evidenced by multiple tenant complaints in 2007 and 2010 regarding heating and appliance problems, though these issues were typically resolved within a few months.

Risk rating

How 670 Monterey Blvd'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
3th percentile

Out of 129 buildings in this neighborhood, 125 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 8.5%
Moderate concern 15.3%
Severe concern 76.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
