Initial analysis

The three-story multi-family residential building at 73-75 Langton Street, currently owned by Michelle Lewis, was constructed in 1906 and contains three units plus ground-floor commercial space. The property has undergone several significant improvements, most notably a comprehensive $37,500 renovation in 2019 that included kitchen and bathroom updates, electrical upgrades, and new plumbing fixtures, along with the removal of knob and tube wiring and installation of modern electrical systems throughout the unit. The building has a documented history of fire safety concerns, with recurring issues related to alarm systems, sprinkler/standpipe systems, and blocked exits between 2020 and 2024, though most have been resolved. Recent maintenance records show attention to building systems, including air conditioning installation in 2008 and various electrical upgrades.

The property has faced challenges with exterior maintenance and environmental conditions in recent months, as evidenced by multiple 311 calls in late 2024 and early 2025 reporting graffiti, garbage, debris, and sewage issues near or around the building. There was a notable building complaint in 2006 regarding a possible illegal unit and lack of fire escape exit, though this was abated later that year. The ground-floor commercial space has undergone various modifications over the years, including bathroom and shower installations in 2006 and partition work in 2000. The building's fire safety systems have required regular attention, with the most recent fire complaint in early 2024 related to alarm systems, which was marked as "Condition Corrected" upon follow-up inspection. While many historical permits show proper maintenance and upgrades, including a reroofing project in 1989, the property has experienced occasional setbacks with compliance and safety systems that warrant monitoring.

Risk rating

How 73-75 Langton 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.
