Rent & eviction protection

Is 1551 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 1968

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 property at 1551 9th Avenue in San Francisco's Inner Sunset neighborhood is a 2-story, 4-unit multi-family residential building constructed in 1968, currently owned by the Michael J Bromberger Revocable Trust. The building has undergone several significant infrastructure improvements over the years, including a complete reroofing project in 2012 costing $12,500, window replacements in 2005 with energy-efficient models, and a major electrical upgrade in 2004 with a 400-amp service underground conversion. Notably, the building faced serious fire safety violations in October 2007 regarding combustible storage and missing directional signs, though these were resolved by December 2007.

Recent complaints and issues include a report of mold/mildew in the bedroom from 2014, and most recently, noise disturbances related to repair work and construction in March 2024. The property has experienced recurring sewer issues recently, with multiple sewage backup incidents reported in May 2024, suggesting potential ongoing plumbing challenges. The building's maintenance record shows regular upkeep, with three separate reroofing projects documented between 2000 and 2012. Recent external issues include multiple reports of vehicles blocking driveways and tree root damage causing walkway problems, though these are primarily affecting public infrastructure rather than the building itself. The most recent issues have been primarily related to external factors rather than structural or internal building problems, with most routine inspections and violations having been resolved promptly.

Risk rating

How 1551 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
