Rent & eviction protection

Is 209 9Th 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.

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 1924
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 5-story multi-family residential building at 209 9th Street in South of Market, owned by 209 9th Street LLC, was constructed in 1924 and contains 6 units. The property underwent significant renovations between 2008 and 2011, including the addition of 2 floors and 3 new residential units, along with comprehensive safety system upgrades. These improvements encompassed the installation of a new fire sprinkler system throughout the building (182 heads), a fire alarm system in common areas, and monitoring work in the elevator machine room, with total costs exceeding $200,000 for these safety enhancements alone.

The renovation period saw some construction-related issues, including complaints in 2011 about unauthorized work on the roof and concerns about falling debris and exposed steel. In 2013, the building received several gas safety violations that were promptly addressed by April 2013, including the need to provide shutoff tools and post instructional diagrams near gas meters. Earlier historical issues from 1995 included a complaint about heating and electrical problems that was quickly resolved. The building's improvement history shows substantial investment in both safety systems and living space expansion, though the 2009 permit for foundation work was withdrawn. All recent building permits and violations have been resolved or marked as not active, with no current open violations on record.

Risk rating

How 209 9Th 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 430 buildings in this neighborhood, 314 are predicted to be safer.

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.

Property class

The assessor's property-class code, which correlates with building type and the violation rates the model expects. This code is grouped with other less-common classes.

12-Month severity forecast
No violation 24.6%
Moderate concern 60.9%
Severe concern 14.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
