40-44 Henry St

Duboce Triangle, SF 94114 3541051 6 units · 3 fl · 1900

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 40-44 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 1900
2 or more units

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.

15+ years since occupancy
Built 1900
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-story, six-unit multi-family residential building at 40-44 Henry Street in Duboce Triangle, owned by Brian F. and Patty L. Topkins, has undergone several significant safety and infrastructure improvements since its construction in 1900. Most notably, the building completed a mandatory soft-story retrofit in 2017 (at a cost of $60,000) to enhance seismic safety, and underwent house trap sewer replacement work in 2016. The property has faced multiple stair-related issues over the years, with building violations and complaints recorded in 2002 and 2008 regarding stair repairs, handrails, and safety compliance, all of which were subsequently addressed. Two routine housing inspections in 2010 showed compliance with housing standards, and a 2008 complaint about unauthorized construction work on rear stairs was resolved. Historical records show earlier maintenance work including reroofing in 1995 (permit expired) and a commercial building demolition in 1996.

The building's violation history (now all abated) includes multiple citations from a 2002 routine inspection for building permit requirements, stair repairs, and fire extinguisher maintenance. A 2010 inspection noted the need for a gas utility shutoff tool, though there have been no active violations since 2010. Recent years have seen typical urban property management issues, as evidenced by 311 calls in 2019-2024 related to street cleaning and parking concerns, though these do not directly reflect on the building's condition or management. The property's current "Completed, CFC Issued" status for seismic work and absence of recent building violations suggest improved structural safety and regulatory compliance, though prospective tenants should note the building's age and previous history of stair-related maintenance issues.

Risk rating

How 40-44 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
33rdpercentile

Out of 287 buildings in this neighborhood, 192 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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