Initial analysis

The property at 620-624 Cortland Ave in Bernal Heights is a two-story, two-unit multi-family residential building constructed in 1909, currently owned by the Isabel McCoy Living Trust. The building has undergone several significant improvements and faced various maintenance challenges over the years. Most notably, there are current plans (filed in 2021) for the creation of two new ADUs on the ground floor and voluntary seismic retrofitting, demonstrating the owner's commitment to modernization and safety upgrades. Previous major improvements include the conversion of overhead service to underground power in 2006 and multiple attempts to construct two-story deck additions between 2000 and 2002, though those permits ultimately expired.

The building's maintenance record shows recurring issues with graffiti, particularly notable in 2023 when there were multiple incidents reported, including an offending tag in April that was addressed under COVID-related enforcement suspensions. Other recent concerns include an overflowing city garbage can (resolved in 2023) and some sidewalk issues noted in 2019 related to tree root damage. The permit history from 2000-2003 shows efforts to complete various improvements, though some permits expired without finalization. The property appears to be actively managed, with recent efforts focused primarily on seismic safety improvements and additional housing units, though the building has experienced typical urban maintenance challenges such as graffiti and street cleaning issues.

Risk rating

How 620-624 Cortland 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
89th percentile

Out of 1276 buildings in this neighborhood, 140 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.

Neighborhood location

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

Neighborhood (ZIP code)

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

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 86.7%
Moderate concern 9.8%
Severe concern 3.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
