Initial analysis

The two-unit residential building at 126-128 9th Avenue, located in the Lake - The Presidio neighborhood, is a two-story flats and duplex structure built in 1909 and currently owned by Robert J Polo. The property has undergone several significant improvements over the years, with the most recent major work being a complete roof replacement in 2018 costing approximately $26,300, which included new laminated fiberglass asphalt shingles and underlayment. In 2009, the building underwent substantial renovations including a bathroom remodel on the second floor, kitchen upgrades in unit 126, and comprehensive plumbing work including a new furnace installation and complete re-piping of waterlines for both units. An electrical upgrade was also completed in 2009, adding multiple receptacles and appliance circuits to the first floor.

The building's maintenance history shows attention to basic infrastructure needs, though there was a notable complaint filed in September 2008 regarding several maintenance issues including an inoperative oven, bathroom problems, inadequate heat, and air leaks from front windows, which was addressed within four days. The property has experienced recurring parking-related issues in the vicinity, with multiple reports of vehicles blocking driveways and parking on sidewalks between 2019 and 2022, though these are external to the building's maintenance record. Recent activity includes a November 2023 Rent Board service request that was resolved by updating ownership records, suggesting proper attention to regulatory matters by current ownership. The building appears to be adequately maintained, with no active complaints or violations on record as of the latest data, and recent permits showing responsible property management through infrastructure upgrades.

Risk rating

How 126-128 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.
