Rent & eviction protection

Is 506-508 Kansas St 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 1927

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 1927
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 two-unit residential building at 506-508 Kansas Street in Potrero Hill, owned by Mario & Carla Caimotto Family, is a 2-story flats and duplex structure built in 1927. The property has undergone some exterior improvements over the years, including the installation of vinyl siding on all sides of the building in 1987 (completed under permit numbers 8705526 and 8705527), and a horizontal modification completed in 1991. More recently, the property received approvals for modifications to its rear yard, including useable open space and off-street parking, as well as an addition of a bedroom to the rear cottage, though the records do not specify whether these improvements were ultimately constructed.

The building's recent history has been marked by significant parking-related issues, particularly between 2022 and 2025. There were multiple incidents of abandoned vehicles reported in 2022-2024, with most vehicles being gone upon inspection. The property has also experienced recurring problems with illegal parking and driveway blocking, with at least two citations issued in 2024, and similar incidents in 2022 where officers were unable to locate the offending vehicles. The most recent parking enforcement action occurred in January 2025, resulting in a citation for a blocked driveway, indicating that parking-related challenges in the vicinity of the property have persisted into 2025. These parking issues, occurring frequently over multiple years, represent the most significant pattern of concerns in the building's recent history, though they primarily relate to street parking rather than building-specific issues.

Risk rating

How 506-508 Kansas 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

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
80thpercentile

Out of 726 buildings in this neighborhood, 145 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
