Rent & eviction protection

Is 101 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.

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.

Built 1905
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 101 Pierce Street in Hayes Valley, owned by 12 One LLC, has undergone several significant improvements and faced various challenges since its construction in 1905. Most notably, the building completed mandatory soft-story retrofitting in 2021 (pursuant to Tier 4 requirements), which included substantial structural improvements such as replacing a brick foundation with concrete and installing new shear walls at a cost of $100,000. The building has also seen recent unit improvements, including a kitchen renovation in Unit 612 in 2021 and gas line installation for a stove in 2022.

In recent years, the property has experienced several maintenance and compliance issues that have impacted resident comfort and safety. In late 2021, multiple housing code violations were documented, including problems with heating systems, window functionality, and door operation, though these were officially abated by November 2022. There was also a notable incident in August 2022 involving graffiti and boarded-up windows on the property. Earlier historical issues included concerns about an unauthorized commercial use of the ground floor in 2004-2005, which was eventually resolved through various planning and enforcement actions. The building's maintenance history shows attention to both structural integrity and resident amenities, with various repairs addressed through building permits, including the replacement of rotted exterior steps in 2019 and multiple fire safety improvements.

Risk rating

How 101 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
7thpercentile

Out of 1027 buildings in this neighborhood, 955 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
