Initial analysis

The 12-unit multi-family residential building at 85 Heather Avenue, owned by Leon Rajninger since 2002, has undergone several significant safety and infrastructure upgrades since its construction in 1951. Most notably, the building completed a mandatory fire alarm replacement in 2022 at a cost of $15,000, addressing compliance issues with current fire code and NFPA standards. The building has also successfully completed a soft-story seismic retrofit in 2016, demonstrating compliance with San Francisco's mandatory seismic safety requirements. Substantial plumbing improvements include a full copper repiping of the building's water lines in 2014, and the building has undergone multiple furnace replacements between 2008 and 2016, ensuring updated heating systems for residents.

The building's history shows proactive maintenance of safety systems, though there have been several fire safety-related incidents and violations. In 2019, there were violations related to sprinkler obstructions and alarm system maintenance, both of which were abated. Multiple fire alarm system activations have occurred, primarily due to malfunctions or unintentional triggers, but no civilian injuries have been reported in these incidents. The building has a record of routine housing inspections, with all identified issues being promptly addressed. Historical violations from 2003 related to smoke enclosure door closers and stairway smoke detectors were all abated by December 2003. Recent fire complaints regarding alarm systems in 2024 were found to have no merit, indicating improved system reliability. While there have been some maintenance-related 311 calls regarding the surrounding area (including sidewalk blockage and encampments) between 2014 and 2019, these were exterior to the building itself and were resolved promptly.

Risk rating

How 85 Heather 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.

Neighborhood percentile
14th percentile

Out of 272 buildings in this neighborhood, 234 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 41.5%
Moderate concern 45.3%
Severe concern 13.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
