85 Heather Ave

Jordan Park/Laurel Heights, SF 94118 1041011 12 units · 3 fl · 1951

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 85 Heather Ave rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1951

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Built 1951
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
14thpercentile

Out of 272 buildings in this neighborhood, 234 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

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.
