Initial analysis

The 2440-2442 Bay Shore Boulevard property is a two-story mixed-use building constructed in 1926, containing three residential units and ground-floor commercial space. The building has undergone several significant transformations, most notably converting the ground floor from a vacant community center to a medical cannabis dispensary (Elevated Systems) in 2016, with subsequent modifications to cannabis retail operations in 2018. This conversion involved substantial improvements including new partitions, finishes, and accessible restrooms, with mechanical and electrical work totaling approximately $25,000. The dispensary underwent a recent administrative permit modification in 2020 to change hours of operation, though no physical changes were made.

The property has seen various improvements and maintenance work over the years, including a 2012 renovation of Apartment #2 involving kitchen remodeling and electrical upgrades, and significant plumbing work including the replacement of sewer lateral and house trap in 2018. The building's maintenance history shows compliance with building codes, though there was a cluster of violations in 2000 related to interior surfaces, including mold/mildew, damaged walls, and lack of smoke detectors, all of which were abated by December 2000. Recent concerns include a December 2024 incident involving a fallen roof tile, and multiple reports of overflowing public garbage cans in early 2025. The property has a history of permit compliance issues in the early 2000s, with several complaints about unauthorized construction and illegal units, though these have been resolved and marked as not active. The ground-floor commercial space has undergone various improvements including new awnings, signage, and storefront modifications, demonstrating ongoing maintenance and investment in the property.

Risk rating

How 2440-2442 Bay Shore 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.

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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

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 76.2%
Moderate concern 19.2%
Severe concern 4.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
