Rent & eviction protection

Is 129 Henry 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 1902
2 or more units
2 units
Property type
Multi-Family Residential

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 1902
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 two-unit residential building at 129 Henry Street in the Duboce Triangle, owned by John D Moriarty 2012 Revocable Trust, is a two-story flats and duplex structure built in 1902. The property's history reveals several significant maintenance and infrastructure issues, particularly in 2021 when there were documented sewer problems including a sewage backup and a water leak involving the house-to-property connection, for which the property owner was deemed responsible for repairs. The building has undergone various permits and modifications over the years, including a completed horizontal addition in 1997 and multiple sidewalk permits, though some earlier permits from the 1980s have expired.

Recent incidents near the property between 2020 and 2025 highlight ongoing maintenance and environmental challenges in the vicinity. These include multiple instances of parking violations on the sidewalk, graffiti, and reports of garbage and debris on public property. The building had two combustible materials fire complaints in October 2012, which were resolved by March 2015, though there was also a hazardous condition incident recorded with no civilian injuries. Additionally, there have been several tree-related concerns reported between 2020 and 2022, including one case where a tree was reported to be damaging property, though an arborist inspection determined it was clear of the building. The most recent work on record was a sidewalk permit issued in 2008, suggesting limited recent external modifications to the property.

Risk rating

How 129 Henry 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
13thpercentile

Out of 287 buildings in this neighborhood, 250 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.

Neighborhood location

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

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.
