Rent & eviction protection

Is 662-664 Church St 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 1905

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.

15+ years since occupancy
Built 1905
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 662-664 Church Street is a three-story, two-unit multi-family residential building constructed in 1905, currently owned by Dunn Bypass Tr Utd since February 2019. The building underwent significant renovations between 2007-2009, including a $300,000 project to fill in light wells, expand the rear, remodel kitchens and bathrooms, and replace the brick foundation with concrete grade beams. The renovation included comprehensive plumbing upgrades with the installation of new appliances, fixtures, and systems, as well as extensive electrical work totaling approximately 300 circuits, 100 lights, and multiple appliance installations. The building has a history of maintaining essential services, with major infrastructure improvements like new sewer lateral installation in 2009, though some permits from this period are now expired.

The property has had several notable issues requiring attention over the years, including a 2010 incident of sewage leakage affecting the neighboring property (which was promptly resolved), and the building experienced fire/smoke damage requiring repairs in 1993. A series of violations was recorded in 2001 related to gas meter safety and fire storage issues, though these were all abated by July 2001. The building received regular routine inspections in 2006 and 2001, all of which are now closed. More recent maintenance has focused on external matters, including various 311 calls concerning street cleaning, graffiti removal, and sewer vent covers between 2021-2024, indicating ongoing attention to building maintenance and neighborhood upkeep.

Risk rating

How 662-664 Church St'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
89thpercentile

Out of 1278 buildings in this neighborhood, 141 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.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
