Rent & eviction protection

Is 670 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 1971

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
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 Klein Family Trust owns this 4-unit, 2-story multi-family residential building located at 670 9th Avenue in the Inner Richmond neighborhood, which was constructed in 1971. The building underwent significant maintenance in 2011 with a completed reroofing project costing $8,800. Three routine housing inspections have been conducted over the years: 2002, 2010, and 2017, with the most recent inspection revealing multiple fire safety concerns that were promptly addressed and abated by May 2017. These violations included issues with fire escape ladders, exit hallway obstructions, garage usage, smoke detection systems, and a requirement for carbon monoxide alarms - all of which were resolved within three weeks of the inspection.

More recent history shows a pattern of parking-related issues near the property, with ten documented reports of sidewalk parking violations between February and April 2024, primarily involving a gray Mercedes van. The most recent property maintenance issue involved an overgrown tree near communication lines, which was addressed and resolved by December 2023 after initial concerns about the timing of the complaint during a property sale emerged. The building has had no recorded fire incidents requiring emergency response, and there have been no recent complaints regarding the building's habitable conditions, suggesting compliance with current housing codes since the resolution of the 2017 violations.

Risk rating

How 670 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
43rdpercentile

Out of 1723 buildings in this neighborhood, 982 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Neighborhood location

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