Rent & eviction protection

Is 471 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 1912

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 1912
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 471 Linden Street in Hayes Valley, owned by Patricia Nguyen and Petersen, is a two-story flats and duplex structure dating back to 1912. The building's maintenance history includes a reroofing project initiated in 1996, the installation of two 40-gallon water heaters in 2012, and electrical upgrades to the basement wiring and stairway lighting completed in 2007. While these improvements suggest ongoing maintenance, the property has experienced significant environmental challenges in recent years. Between 2023 and 2025, there have been multiple incidents requiring street cleaning services, including reports of human waste, medical waste (needles), garbage debris, and a sidewalk defect involving a lifted surface. The area has also faced parking-related issues, with multiple reports of illegal parking, including blocked driveways and an abandoned vehicle, though these cases were generally resolved without finding the offending vehicles. An open case from October 2024 regarding an overgrown tree near communication lines indicates an ongoing maintenance concern. The clustering of sidewalk cleaning requests in 2023 suggests particular attention to the immediate surroundings has been necessary, though all reported cases have been marked as resolved.

Risk rating

How 471 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
87thpercentile

Out of 1027 buildings in this neighborhood, 134 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
