Initial analysis

The property at 3457-3459 Mission Street is a two-story mixed-use building constructed in 1920, containing 3 residential units and ground-floor commercial space, currently owned by the Liao Family Trust. The building underwent significant rehabilitation in 2019-2021, including the addition of two residential units (legalized per NOV #201933911) with complete renovations of bathrooms and kitchens, installation of a new fire sprinkler system, and structural reinforcement of floors and roof framing. Multiple compliance improvements were made, including a sprinkler monitoring system (2021), electrical updates with new subpanels (2019), and accessibility improvements to the entrance (2022). Historical violations from 2015-2019 related to building maintenance, heating, and safety systems have all been resolved, with final abatement in December 2022.

The building has experienced several maintenance and compliance issues that were addressed through permits and inspections. Notable past problems included water intrusion incidents in early 2019, heating system deficiencies, and fire safety concerns that triggered multiple Notices of Violation. All documented violations are now marked as abated, and recent work has focused on improving safety systems including fire sprinklers, monitoring equipment, and accessibility features. The property maintains an active restaurant use (Nena's) with alcohol service, and has undergone periodic inspections for fire safety compliance, including kitchen hood maintenance requirements. Recent building maintenance history shows compliance with safety requirements, though some permits from 2019 (for furnaces and plumbing work) are marked as expired. The most recent building-related issue was a mechanical equipment installation complaint from October 2022, which has since been resolved.

Risk rating

How 3457-3459 Mission 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.
