Rent & eviction protection

Is 129-131 Saturn 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 1963

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 two-unit residential building at 129-131 Saturn Street in Corona Heights, owned by the Roschinger Family Trust since 2001, has undergone several significant maintenance and improvement projects over the years. Most recently, as of March 2023, the property received new siding on its rear facade at a cost of $54,600, covering an area of 30x55 feet. A permit filed in January 2025 indicates upcoming repairs to address dry rot on six treads of the rear stairs, including the installation of through bolts to reinforce posts and railings. The building's maintenance history shows regular upkeep going back several decades, including windows replacement in 1997, roofing work in 1994, and vinyl siding installation in 1987, though the earlier permits from 1994 and 1997 have expired.

The property has experienced multiple reports of abandoned vehicles in the vicinity between 2011 and 2018, though all these incidents were resolved when the vehicles departed before enforcement could take action. A notable tenant buyout occurred on November 21, 2017, involving three tenants and compensation of $9,000. While the building's maintenance record shows regular upkeep, with the most recent siding replacement and upcoming stair repairs, it's worth noting the dry rot issue affecting the rear stairs, which could potentially impact safety if not properly addressed.

Risk rating

How 129-131 Saturn 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
95thpercentile

Out of 348 buildings in this neighborhood, 17 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.

Neighborhood (ZIP code)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
