Rent & eviction protection

Is 411 Pierce 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.

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 apartment building at 411 Pierce Street in Hayes Valley, owned by Plaza Group LLC, consists of 9 units and was constructed in 1900. The building has undergone several significant improvements over the past decade, with the most notable being the addition of an accessory dwelling unit (ADU) in 2017-2019, which included comprehensive fire safety upgrades such as a new fire sprinkler system and alarm installations costing over $100,000 combined. Recent maintenance records show consistent attention to fire safety systems, though there have been recurring issues, including three fire extinguisher-related complaints between 2015-2024 and a 2021 violation for sprinkler/standpipe systems that was subsequently corrected. A concerning active complaint from December 2020 asserts that the building, classified as a multi-unit soft-story structure, has not been properly addressed under the city's soft-story property mandate, raising potential safety concerns.

Recent infrastructure improvements include a 400-amp electrical service upgrade in 2018 and various unit renovations, including a 2015 kitchen and bathroom remodel in Unit 3. The building's history shows regular maintenance of essential systems, though multiple fire safety violations and complaints suggest ongoing challenges with maintaining compliance across all safety systems. There have been various routine safety inspections throughout the years, with the most recent involving the building's soft-story classification. The property has experienced some external issues as documented in 311 calls, primarily related to general cleaning and parking concerns, though these are less relevant to the building's internal conditions.

Risk rating

How 411 Pierce 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
22ndpercentile

Out of 1027 buildings in this neighborhood, 801 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 size

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

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