Initial analysis

540 Stockton Street is a 4-story, 11-unit multi-family residential building constructed in 1922, currently owned by the Zaleka Partnership LP and located in the Financial District North neighborhood. The building has undergone numerous renovations over the years, with significant unit upgrades occurring between 2007 and 2012, including kitchen and bathroom remodels in units 1, 2, 3, 4, 6, 7, 8, and 9, totaling several hundred thousand dollars in improvements. Recent maintenance activity includes boiler and backflow system work completed in 2023, with the installation of new 400-amp 3-phase service in 2010 representing a major electrical system upgrade.

The property has experienced various compliance and safety issues over its history, with the most recent concerns including a 2024 complaint about entry signaling devices and multiple reports of garbage and debris in 2024. Previous violations included problems with fire safety systems (sprinkler/standpipe systems, alarm systems, and extinguishers), rodent infestations, and unauthorized vacation rentals in several units. A significant period of unauthorized construction work was reported in 2007-2009, during which time the owner allegedly attempted to convert the building to a boutique hotel. The building has been subject to periodic fire safety inspections, with most issues being promptly corrected, though a recent 2024 fire complaint regarding sprinkler/standpipe systems was found to have no merit. The property has maintained active records with the Department of Building Inspection, demonstrating regular updates and compliance efforts, particularly regarding fire safety systems and unit improvements.

Risk rating

How 540 Stockton St'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
34th percentile

Out of 145 buildings in this neighborhood, 96 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 29.5%
Moderate concern 49.9%
Severe concern 20.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
