Initial analysis

The 6-unit, 3-story multi-family residential building at 17-23 Hoff St in the Inner Mission, owned by Hdi Jasper LLC, has undergone significant modernization and safety improvements since its construction in 1910. Most notably, in 2021-2022, the property underwent substantial renovations including the conversion of an existing garage/storage area into four additional dwelling units (ADUs), installation of a comprehensive fire safety system including sprinklers and alarms, and major infrastructure upgrades such as a new 400-amp electrical service with 10 meters, complete rewiring, and a new roof. Unit #17 received kitchen and bathroom remodeling in 2022. The building successfully completed its mandatory soft-story seismic retrofit in 2014, and all recent building permits, including fire safety improvements and ADU conversions, have been completed or properly filed.

Historical records indicate the building had some safety concerns in 2003 regarding fire proofing, stairs, and handrails, which were resolved by December 2003. There were several fire-related incidents recorded between 2016-2022, though none resulted in injuries or serious damage. Recent 311 calls from January 2025 primarily relate to external issues such as graffiti and sidewalk cleaning, while four shared spaces fire complaints from October 2023 were either corrected or marked as duplicates. The building's fire safety systems were significantly upgraded in 2021-2022, including the installation of fire sprinklers, alarms, and other safety features, suggesting improved resident safety compared to earlier years. However, it should be noted that there are currently several open 311 calls from January 2025 regarding building maintenance and public space cleanliness.

Risk rating

How 17-23 Hoff St'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

Number of units

12-Month severity forecast
No violation 30.6%
Moderate concern 62.3%
Severe concern 7.1%
