Bernal Heights, SF 94110 5666016 3 units · 2 fl · 1890

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 417-419 Cortland 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.

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.

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 three-unit residential building at 417-419 Cortland Avenue in Bernal Heights, owned by Judit M. Mandoki and Imre L. Mandoki, was constructed in 1890 and stands two stories tall. Over the past seven years, the property has generated a total of 46 service requests through the city's 311 system, with records indicating a particular cluster of issues in 2024-2026. Most notably, there was a sewage discharge incident from a side sewer vent in July 2026, which was resolved through field work. The building has also experienced recurring issues with sidewalk maintenance, with two requests in October and November 2024 specifically addressing the need to clear paths of travel, both of which were fully abated. Other documented incidents include multiple instances of garbage and debris removal, including furniture in June 2025 and glass in March 2025, and a fallen tree report in June 2025 that was marked as a duplicate. While these service requests may suggest ongoing maintenance challenges, it's worth noting that there has been only one fire incident recorded in the past seven years, indicating no significant fire safety concerns. The building's age and the number of service requests logged over the past seven years suggest typical urban property maintenance patterns, though the recent sewage discharge incident warrants attention.

Risk rating

How 417-419 Cortland 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
21stpercentile

Out of 1276 buildings in this neighborhood, 1008 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
