Rent & eviction protection

Is 1378 47Th 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 before 1979
Built 1913
2 or more units
3 units
Property type
Multi-Family Residential
Zoning
RH2
Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1913
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 three-unit, three-story apartment building at 1378 47th Avenue in the Outer Sunset, owned by the Debra J Tyler Living Trust, has experienced several significant maintenance issues and ongoing concerns in recent years. Most notably, there are multiple active building violations filed in December 2024 that require attention, including problems with roof weatherproofing, drainage pipes, door hardware, and the need for fire extinguishers. Recent complaints from December 2024 document water intrusion, possible mold, and structural concerns, particularly affecting the third-floor unit C, along with electrical inoperability and ceiling leaks. The building has a history of water-related issues, including a major flooding incident in 2015 that affected both the upper and lower units, requiring substantial interior repairs and electrical examination. Earlier maintenance records show various repairs, including a 2007 electrical service upgrade, plumbing work in 2014 for sewer repairs, and several permits in 1992 addressing rotting stairs and dry rot issues. While there have been historical violations related to safety equipment and infrastructure (such as stairs and decks) in 2002, most were promptly addressed. The most recent building permit, issued in January 2025, indicates forthcoming reroofing work with specific safety precautions regarding open flames or torches.

Risk rating

How 1378 47Th 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
13thpercentile

Out of 632 buildings in this neighborhood, 550 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.
