Initial analysis

The property at 4079-4081 Mission St is a two-unit, two-story multi-family residential building located in Bernal Heights, constructed in 1965 and currently owned by the Samantha M Li Living Trust. The building has undergone several significant improvements over the past decade, including a kitchen reconfiguration and associated plumbing and electrical work in 2019 (cost: $15,000), window and patio door replacements in 2017 ($3,769), and major structural repairs to wood decking and roofing in 2010 (totaling $24,500). However, the building currently has multiple active violations from 2017-2018 that warrant attention, including issues with window sashes and weather stripping, as well as an egress obstruction that was reported in January 2018 and remains unresolved. Additional maintenance concerns were documented in 2017, including problems with window closure, toilet functionality, and heating system performance.

Recent history includes a noise complaint in September 2023 regarding early morning construction work, though this complaint is no longer active. The property has had one electrical service change in 2007 and various maintenance issues reported through 311 calls, primarily related to garbage, debris, and graffiti in the surrounding area, though these are external to the building itself. While the property has seen regular maintenance and improvements over the years, the persistence of certain violations from 2017-2018 is notable, though the building has received multiple permits for various improvements and repairs, suggesting ongoing maintenance efforts by ownership.

Risk rating

How 4079-4081 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.

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.
