Initial analysis

This three-story, two-unit multi-family residential building located at 1448-1450 Valencia Street in the Inner Mission area was built in 1900 and is currently owned by the Aisling Ferguson Revocable Living Trust. The property suffered significant fire damage in October 2013, rendering both units unsafe for occupancy with structural damage to both units, though it was later rehabilitated with a completion date of 12/04/2018. The extensive renovation work conducted between 2015 and 2017 included the installation of a new fire protection sprinkler system, complete rewiring of both units with modern electrical components, new plumbing systems including multiple shower pans and fixtures, and structural improvements such as concrete landings and stairs. The building's systems were comprehensively upgraded during the renovation, including water heater installation, radiant heating, and new utility connections.

Recent service records from 2023-2024 show various maintenance and municipal service requests, mostly relating to external issues like parking violations, graffiti, and street maintenance concerns. Planning records indicate the building underwent a vertical expansion with front and rear decks, and there were some historical compliance issues noted regarding vinyl siding installation and an unpermitted advertising sign. The most recent fire safety records show one false alarm activation with no actual fire or injuries reported. The property's recent history suggests all major systems have been upgraded to modern standards, though the building's age and location have resulted in typical urban maintenance issues being reported through 311 services.

Risk rating

How 1448-1450 Valencia 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
