Initial analysis

The 4-unit multi-family residential building at 31-33 Cortland Avenue in Bernal Heights, owned by Gupta Deepa, was constructed in 1905 and has undergone several significant renovations and improvements over the past decade. Most notably, between 2016-2017, the building received comprehensive updates including the installation of a new fire sprinkler system throughout, complete electrical rewiring and panel replacement, kitchen and bathroom remodeling in multiple units, and various plumbing upgrades. A sewer line replacement was completed in October 2021. However, there is currently an active building violation (filed in May 2024) regarding unauthorized removal of a rear spiral staircase that was originally approved under a 2016 permit, which has resulted in monthly monitoring fees. The building has experienced some maintenance issues, including a water damage remediation project in 2019 and a sewage backup incident reported in December 2024.

Recent municipal interactions include a 2023 report of fallen trees in the vicinity, and various 311 calls throughout 2024 regarding sidewalk parking, abandoned vehicles, and urban forestry maintenance issues. The property has a history of building violations from 2008 related to fire safety and window maintenance, though these were eventually abated. Current permits indicate efforts to designate unit #33A as Intermediate Length Occupancy (ILO), while earlier planning applications proposed adding dormers and additional bathrooms. The building's safety systems have been regularly updated, including the installation of smoke detectors and fire sprinklers, though a 2016 complaint regarding lead paint handling was recorded, which was subsequently resolved.

Risk rating

How 31-33 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
