Rent & eviction protection

Is 416-418 Linden 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 1909
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 1909
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 416-418 Linden Street in Hayes Valley, owned by Henry Chuang and Jorda Bowler, has undergone significant renovations and improvements over the past two decades. Most recently, in 2021, substantial work was completed in Unit 416, including interior reconfiguration to add a bedroom and half bath, along with the installation of a new mini-split HVAC system. The building's systems were notably upgraded with the installation of a comprehensive mini-split system featuring multiple indoor units and an outdoor condenser. In 2009, significant improvements were made to Unit 418, including a complete kitchen relocation and remodel, bathroom renovation, and electrical system upgrades. Historical records indicate that this property, originally constructed as an 8-unit building in 1909, was legally recognized as a 2-story building with 2 residential units in December 2020.

The building has experienced minimal safety concerns, with only one notable issue reported in 2002 regarding unsafe exterior flues, which was promptly resolved within two days. Other historical complaints, such as concerns about paint scraping in 1998, were also quickly addressed. Recent municipal service calls from 2024 have primarily related to street cleanliness and parking enforcement issues in the vicinity, rather than building-specific problems. The property has maintained compliance with building codes and regulations, as evidenced by the successful completion of numerous building, plumbing, and electrical permits, and the approved window replacement project in front. The recent renovations have substantially improved the building's amenities and comfort, particularly through modern HVAC system installations and interior upgrades.

Risk rating

How 416-418 Linden 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
97thpercentile

Out of 1027 buildings in this neighborhood, 31 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

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

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.
