Rent & eviction protection

Is 1470 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.

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

Just-cause eviction

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 12-unit, 3-story apartment building at 1470 9th Avenue in the Inner Sunset, owned by Tan Trust, has undergone significant improvements and modifications since its construction in 1963, with the most substantial work occurring between 2017-2020. Notably, the building added two accessory dwelling units (ADUs) in 2017 as part of a $180,000 project, followed by comprehensive fire safety upgrades including a new NFPA 13 fire sprinkler system ($32,712) throughout the ground floor in 2019 and fire alarm system modifications in 2020 ($15,000). The building has completed its mandatory soft-story retrofit (Tier 3) and met fire safety requirements through several inspections and upgrades, including recent work in December 2023 for sprinkler maintenance and boiler permit renewals.

The property has experienced some maintenance challenges over the years, including a notable heating complaint in 2016 regarding insufficient temperatures in one unit during winter, and several historical boiler permit issues that have required attention between 2001 and 2020. While there have been multiple fire safety complaints registered between 2005 and 2023, these have generally been resolved quickly, with most being determined to have "No Merit" or were promptly corrected. Recent activity suggests ongoing maintenance and compliance efforts, as evidenced by the December 2023 renewal of sprinkler and plumbing permits. The building has also experienced periodic issues with parking violations and sidewalk maintenance, with several complaints about blocking driveways between 2016-2024, though these are external to the building's operations.

Risk rating

How 1470 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
2ndpercentile

Out of 1493 buildings in this neighborhood, 1463 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
