Initial analysis

830 Hayes Street is a three-story, 24-unit multi-family residential building constructed in 1927 and currently owned by the William F Assali Trust. The building is classified as a Tier 2 soft-story structure and has successfully completed mandatory seismic retrofitting in 2019, including revisions to moment frames and shearwalls, with work valued at $120,000. Recent improvements include kitchen and bathroom renovations in Unit 208 (2019) and various units undergoing similar upgrades over the years, with maintenance work to address issues like elevators, roof work, and electrical system improvements documented through multiple completed building permits.

The property has experienced several maintenance and safety-related issues over its history, including a significant hoarding and possible health concern in 2016, multiple fire safety inspections requiring corrections (2019, 2021, and 2022) regarding extinguishers and exit maintenance, and routine safety inspections in 2007 revealing various violations related to heat, fire escape maintenance, and gas utility shutoff tools. The building has had some plumbing and heating incidents requiring attention, including a flood in 2003 and inadequate heat complaints in 2003 and 2007, all of which were subsequently resolved. As of July 2024, there is an active noise complaint regarding amplified sound, and an open issue with an overgrown tree blocking the sidewalk was reported in July 2024. The most recent building complaint from November 2023 regarding common areas is currently active, while past violations have generally been addressed and abated, with the most recent notable governance being primarily focused on parking-related issues outside the building's premises.

Risk rating

How 830 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

Out of 305 buildings in this neighborhood, 268 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.

Number of units

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

Building size

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

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 30.5%
Moderate concern 34.4%
Severe concern 35.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
