Rent & eviction protection

Is 682 9Th 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.

Built before 1979
Built 1900
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 1900
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

Located in San Francisco's Inner Richmond district, 682 9th Avenue is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Castleton Dillon. The property has undergone several significant renovations over the past two decades, with the most recent major work occurring in 2022, including a complete kitchen remodel ($29,000) that upgraded electrical and plumbing systems to current codes. Prior improvements include a substantial 2015 renovation that updated both bathroom and kitchen facilities across the units, featuring new cabinets, fixtures, and appliances, along with the installation of high-efficiency furnaces ($55,000). Earlier maintenance work included the replacement of 33 windows in 2004 (from aluminum to vinyl) and historical updates to the roof and rear stairs in the 1990s.

The building's maintenance record shows regular upkeep, though there have been some concerning incidents. In 2022, there were construction-related complaints filed regarding unauthorized work, after-hours construction, and noise issues, though these complaints are currently listed as not active. The property has experienced two notable fire safety incidents in May 2021 involving sprinkler/standpipe systems and alarm systems, both of which were resolved with conditions corrected by June 2021. Other historical issues include a 2018 electrical non-hazard complaint, and various parking and public space concerns around the property perimeter, though these do not directly reflect on the building's condition. Two 311 calls from 2020 regarding trees damaging property and a defaced sign were resolved, and a 2019 building inspection complaint was closed with resolution noted.

Risk rating

How 682 9Th 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
92ndpercentile

Out of 1723 buildings in this neighborhood, 138 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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