Initial analysis

The property at 1300-1310 12th Avenue is a two-story mixed-use building constructed in 1955, consisting of 10 residential units above a commercial space, currently owned by the Colabianchi Carol A Revoc Trust. The building has undergone several significant improvements over the past two decades, including a completed soft-story retrofit in 2018 (classified as Tier 4) that addressed seismic safety concerns in both the residential and commercial portions of the building. More recent commercial modifications include the conversion of a former salon into a limited restaurant cafe in 2021, which has included both plumbing and electrical upgrades.

The building has experienced some maintenance and compliance issues over its history, particularly in 2002 when violations were issued regarding lighting fixtures and back stairs, though these were all resolved by December 2002. There have been three notable building complaints in recent years: in 2021 regarding work beyond the scope of a permit (active as of the last known status), in 2019 concerning common area maintenance, and in 2022 regarding expired permits but this was promptly resolved. The property has also seen its share of plumbing and electrical upgrades, including a 2020 hot water flue replacement and common area rewiring related to the soft-story retrofit.

Risk rating

How 1300-1310 12Th Ave'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

Out of 1493 buildings in this neighborhood, 1418 are predicted to be safer.
