Initial analysis

The 1173 Hayes Street property is a four-story, seven-unit multi-family residential building constructed in 1912 in the Alamo Square neighborhood. The building has undergone several significant improvements and faced various challenges over the years, with the most recent major work being a complete reroofing project completed in December 2023 at a cost of $23,100. Of particular note is the building's completion of the mandatory Soft Story Retrofit Program in 2020, following a period of non-compliance that generated multiple violations between 2014-2017, with the final certification issued in 2023. The building has experienced recurring maintenance issues, particularly with its heating system, electrical infrastructure, and fire safety components, including several instances of heater outages (2009), electrical wiring violations (2009-2014), and fire alarm system problems (multiple years). Historical concerns have included unauthorized basement occupancy issues (2009-2016) and various building system failures that prompted numerous housing inspections. While most violations have been addressed and closed, including several fire safety violations in 2009 and a blocked exits complaint in 2019, the building has continued to experience maintenance challenges as evidenced by recent 311 calls regarding graffiti, garbage, and debris issues (2024-2025). The property has undergone several essential repairs over the years, including stair repairs in 2004, boiler system improvements in 2007, and various electrical upgrades, demonstrating ongoing maintenance efforts by the current ownership.

Risk rating

How 1173 Hayes 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
36th percentile

Out of 305 buildings in this neighborhood, 195 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 34.0%
Moderate concern 38.2%
Severe concern 27.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
