Rent & eviction protection

Is 1801 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 1923

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 1923
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 1801 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1923, currently owned by the Gracia Family Trust. The building has undergone several significant improvements over the past two decades, including foundation work in 2015 involving the voluntary replacement of 32 feet of concrete footing at a cost of $26,000, plumbing work for a gas houseline extension in 2010, and the installation of a Ufer ground electrical system in 2015. A building complaint was filed in April 2020 regarding extensive cement coverage of side yards, with approximately 720 square feet covered on the north side, though this complaint is currently listed as not active.

The most recent and concerning incident on record was a gas leak (natural gas or LPG) situation, though no civilian injuries were reported. The property has experienced recurring issues with illegal parking, particularly sidewalk blocking and driveway obstructions, with multiple identical complaints documented throughout 2023-2024, though many of these were either not validated or unable to be responded to by parking enforcement. There were also some municipal service calls related to sidewalk maintenance, including a missing side sewer vent cover incident in September 2022 which was resolved, and street cleaning issues addressed by Recology in 2022 and 2020. The building's permit and violation history suggests ongoing maintenance and infrastructure upgrades, particularly regarding safety systems like gas lines and electrical grounding, though the nature and extent of the cement coverage issue reported in 2020 remains unclear from the available records.

Risk rating

How 1801 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
37thpercentile

Out of 1493 buildings in this neighborhood, 941 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
