Initial analysis

The 1840 Franklin Street property is a three-story, multi-family residential building with 7 units, constructed in 1914 and currently owned by the Robert J Maron Living Trust. The building has undergone several significant safety and infrastructure improvements over the past decade, with the most recent being a 2023 fire alarm system upgrade costing $31,200 to comply with current fire safety codes. This followed previous fire safety improvements including a 2023 electrical modification to install low-frequency sounders in sleeping areas, and multiple fire alarm system installations and upgrades between 2011-2013. The building has completed its mandatory Tier 3 soft-story seismic retrofit as confirmed by the CFC issuance, though earlier retrofit efforts from 2017 were initially expired due to delayed completion.

The property's maintenance history shows attention to critical systems, with a 2020 reroofing project costing $20,000, and a successful resolution of multiple building violations from 2016 and 2002 related to fire safety equipment, egress, and general maintenance. While several 311 calls regarding parking issues have been recorded in recent years, these are external to the building's operations. The most recent building inspection complaint in 2023-2024 was resolved with proper alarm system corrections. The building's documented history suggests regular maintenance and upgrades to meet current safety standards, with prompt responses to fire safety issues as evidenced by multiple "Condition Corrected" resolutions for alarm system complaints over the years.

Risk rating

How 1840 Franklin 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 963 buildings in this neighborhood, 636 are predicted to be safer.
