Initial analysis

Located in Telegraph Hill, this three-story multi-family residential building at 19-21 Bob Kaufman Alley was constructed in 1905 and contains 5 units. The property has undergone several significant renovations and faced various maintenance challenges over the years. Most notably, in 2013, the building encountered violations related to weatherproofing and lead paint concerns on the exterior siding, which were abated by October 2014 following repair work that cost approximately $2,000. A substantial renovation project was completed in 2008, involving the replacement of 12 wood windows, remodeling of two kitchens and bathrooms, and comprehensive electrical upgrades on the second and third floors, with a total investment of $30,000 for the improvements. More recent maintenance includes a water supply line repair completed in 2020.

The building's history also shows attention to infrastructure and safety updates, with various plumbing and electrical improvements documented between 2007-2008, including the installation of numerous lighting fixtures, switches, and receptacles throughout the property. While there have been some unauthorized work incidents reported in 2007-2008 regarding window installation and interior modifications, these issues were subsequently addressed. The property has experienced multiple parking enforcement calls in 2024, though most were resolved without locating the offending vehicles. Recent complaints in 2024 have primarily related to entertainment noise and street cleaning issues, with inspectors finding businesses compliant with permit conditions during their visits. The building's maintenance record shows periodic attention to both interior and exterior upkeep, with appropriate permits obtained for most significant work, though some historical violations have required follow-up corrections.

Risk rating

How 19-21 Bob Kaufman Aly'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.
