Initial analysis

Located in San Francisco's Inner Sunset neighborhood, this two-unit multi-family residential building at 1391-1393 18th Avenue was constructed in 1947 and has undergone several significant improvements over the years. Most notably, in 2015 the property underwent substantial renovations including a complete kitchen remodel, bathroom updates, and electrical work across multiple floors, with proper permits totaling approximately $25,000. The building also received a new roof in 2015, with the work costing $9,500 and involving the installation of a modified bitumen system. Earlier improvements include a 2003 addition of a room and full bathroom in the rear garage, and a kitchen cabinet renovation in 2007.

The property's maintenance history shows regular upkeep, though the 311 call history reveals some environmental challenges in the immediate vicinity, including instances of graffiti (2009), waste cleanup needs (2014 and 2022), and one report of an abandoned vehicle (2009), all of which were resolved through appropriate city services. The most recent building work was completed in 2015, and the property's systems appear to have been significantly updated during that renovation period, including comprehensive electrical work. Historical records show a variety of upgrades and maintenance work performed over the years, including plumbing and electrical updates corresponding with each major renovation project, indicating reasonable attention to infrastructure maintenance.

Risk rating

How 1391-1393 18Th 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
