Rent & eviction protection

Is 1806-1808 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 1947

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 1947
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 1806-1808 9th Avenue was constructed in 1947 and has undergone several significant improvements over the years. Most notably, in 2008, the building underwent substantial exterior work with the removal and replacement of damaged siding and stucco on the front facade, a project costing $8,500. Earlier renovations included a kitchen remodeling project on the upper floor in 2003 and some electrical work involving underground pipe conversion in 2004. While there were attempts in 1989 and 1991 to add a third-level deck to the rear yard, these proposals were either withdrawn or disapproved.

The property has experienced some infrastructure challenges, particularly regarding sewer systems. In December 2017, there were two documented incidents involving sewage issues - one involving flooding on the street and another from a catch basin. More recently, the building's surroundings have been affected by common urban issues, including illegal postings (2021), graffiti (2020), and parking violations (2018-2019). The immediate area has also experienced occasional waste management challenges, with multiple reports of overflowing city garbage cans and street cleaning issues in 2023. While these external factors don't directly impact the building's condition, they provide context about the neighborhood environment. The building's documented permit history suggests proper attention to maintenance and improvement requirements over the years, with no recent major works or permits indicating current structural concerns.

Risk rating

How 1806-1808 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
87thpercentile

Out of 1493 buildings in this neighborhood, 194 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
