Initial analysis

The two-story, 11-unit multi-family residential building at 300 Monterey Blvd in the Sunnyside neighborhood, owned by Owen D & Mildred E Conley R, was constructed in 1988 on the former site of an Arco service station. The property has undergone several significant improvements and faced multiple maintenance challenges over its lifespan. In 1998-1999, the building underwent substantial fire safety system upgrades, including the installation of a new fire alarm system and sprinklers. More recent concerns include multiple fire safety inspections showing recurring issues with fire extinguishers (most recently resolved in October 2024) and electrical systems (resolved August 2023). The building has experienced several health and safety challenges, particularly in 2021-2022 when multiple violations were documented related to mold/mildew around windows, insect infestations, and other sanitation issues, though these were officially abated by March 2022.

The property has a history of plumbing issues, including a complete sewer line replacement in 2008, and has faced various maintenance problems that indicate ongoing challenges with building systems and resident comfort. Complaints about heating systems, window sealing, and carpet conditions were documented in 2019, while routine inspections of common areas were conducted in 2014 and 2010. The building's fire safety systems have been a recurring focus, with multiple inspections showing varying levels of compliance. Recent 311 calls from 2023-2024 show typical urban building maintenance issues, including parking violations and graffiti, along with a sewage backup incident in January 2024 that was promptly resolved. The property's records show regular monitoring and response to violations, with most issues being addressed through official channels, though some historical permits and inspections have expired or been cancelled.

Risk rating

How 300 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
4th percentile

Out of 129 buildings in this neighborhood, 124 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.

NOV rate, owner's portfolio

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

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.

12-Month severity forecast
No violation 8.1%
Moderate concern 45.6%
Severe concern 46.3%
