Initial analysis

The property at 1860 9th Avenue, located in San Francisco's Inner Sunset neighborhood, is a two-story, two-unit multi-family residential building constructed in 1900. The building underwent significant vertical and horizontal expansion in 2016, converting it from two stories to a four-story structure, which included adding bedrooms and bathrooms. This major renovation was followed by the installation of comprehensive fire safety systems in 2022, including a new fire sprinkler system with 88 heads, monitoring equipment, and related fire safety infrastructure costing $71,400 combined. The building has been fully renovated to support four units, with extensive updates including new furnaces, plumbing systems, and electrical work. Between 2021-2022, all four units received complete electrical wiring upgrades, including bathrooms, kitchens, and laundry facilities.

The renovation period (2021-2022) generated several complaints from neighbors, including concerns about construction noise after permitted hours, construction work exceeding approved scopes, and air quality issues during construction. More recently, in March 2023, there was a complaint regarding light trespass affecting neighboring properties, though this case is currently not active. The property has undergone thorough infrastructure upgrades, including a 300 to 400 amp electrical service upgrade, installation of radiant heating systems in Units 2 and 3, and various plumbing improvements. Records show regular maintenance concerns typical for the area, including sidewalk cleaning and occasional parking issues. The building's transformation from a two-unit to a four-unit structure has been completed, with all major permits properly documented and generally marked as complete or resolved, except for one parking-related issue from September 2024.

Risk rating

How 1860 9Th 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.
