Rent & eviction protection

Is 3319 Clay 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 before 1979
Built 1910

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1910
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 3319 Clay Street is a two-unit, two-story multi-family residential building located in Presidio Heights, built in 1910 and currently owned by Thompson Street Trust. The building underwent significant renovations in 2016-2017, including a complete upper unit remodel featuring a new kitchen, three bathrooms, and one powder room, along with extensive electrical rewiring and plumbing upgrades costing approximately $200,000. The renovation work did experience some controversy, with a building violation filed in December 2016 regarding unpermitted construction, though this was eventually abated by December 2018. More recent improvements included the installation of new stairs, a sliding skylight, a redwood roof deck, and upper unit furnace replacement in 2017.

The building's infrastructure improvements included complete electrical rewiring, plumbing upgrades with new water heaters, and heating system modifications. Outside the building, there have been recurring issues with tree roots damaging the sidewalk, with three reports in 2023 and one sidewalk defect report in 2020 that remains open. Parking-related incidents have been documented through 311 calls, including illegal parking cases in 2018 and 2021, while a 2017 roof-related permit was filed with minimal associated cost. A 743 smoke detector activation incident was recorded with no injuries or fire damage noted. The building's earlier history shows reroofing work completed in 1992 and 1993, though permits for these projects are now expired.

Risk rating

How 3319 Clay 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
64thpercentile

Out of 181 buildings in this neighborhood, 65 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.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Estimated permit spend (past 7 years)

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