Rent & eviction protection

Is 524 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 before 1979
Built 1977
2 or more units

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.

15+ years since occupancy
Built 1977
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

524 Kansas Street is a 4-story, 4-unit multi-family residential building located in Potrero Hill, built in 1977 and currently owned by Masami Hattori & Petra Mofa. The building has undergone several significant renovations and improvements over the years, with the most recent work being a reroofing project completed in 2023 at a cost of $14,800. A major renovation occurred in 2014-2015 involving the relocation of one unit above the garage, remodeling of a second-floor unit, and the installation of a comprehensive fire sprinkler system throughout the building, including 80 heads and a 2-inch underground fire service, costing a total of $430,000. The building faced several challenges in 2017, including multiple fire code violations related to blocked exits, combustibles in exit paths, smoke alarm issues, and sprinkler service concerns, though these violations were subsequently abated.

The property has experienced various maintenance and operational issues, including plumbing problems in 2015 (busted pipe, water leak), construction-related complaints about dust and debris, and some parking enforcement concerns in the surrounding area. In 2019, there were reports of medical waste (needles) near the property that were resolved by city services. Of particular note is the building's history with short-term rentals, as evidenced by planning records showing a violation in 2019 regarding high-volume short-term rentals on Airbnb, which was eventually resolved when owners ceased hosting and transitioned all units to long-term rentals. The building's maintenance history shows regular upkeep, including window and siding replacement in 2010, installation of new furnaces in 2015, and various unit-specific improvements over the years.

Risk rating

How 524 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
47thpercentile

Out of 726 buildings in this neighborhood, 385 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
