Rent & eviction protection

Is 180 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.

Built 1910
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 property at 180 Cortland Ave in Bernal Heights is a two-unit, two-story building constructed in 1910, currently owned by Jonathan P & Susan E Walthe. The building has undergone significant renovation work between 2019-2021, particularly involving Unit B, which was relocated from the third floor to the first floor with an updated layout including one bedroom, one bath, and a combined kitchen/living area. This renovation included exterior work with stucco application on the north and east sides of the first story, as well as grading adjustments and concrete work at the ground floor level. All major renovation work was completed and received final inspection approval by December 2021.

The building has generated a total of 112 311 service requests over the past seven years, with the most recent cluster of complaints (three requests) occurring in July 2026, primarily related to building markings and waste (though many of these issues appear to be more related to the immediate vicinity rather than the building itself). There were also three reports of abandoned vehicles and illegal parking in early to mid-2026, though these were external to the property. The relatively low number of building permits (three in seven years) and the formal completion of major renovation work suggest that the building's systems and structure are likely stable, though the high volume of service requests warrants attention to ongoing property management in the surrounding area.

Risk rating

How 180 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
60thpercentile

Out of 1276 buildings in this neighborhood, 510 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
