Rent & eviction protection

Is 274-276 Duncan 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 1890

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 1890
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

This two-unit residential building at 274-276 Duncan Street in Noe Valley, owned by Fsh LLC, was originally constructed in 1890 as a two-story structure. The property has undergone significant transformations in recent years, with major work commencing around 2015 when a vertical addition and extensive remodeling project was proposed, ultimately costing over $718,600. This work included adding three new levels, constructing two new kitchens, and adding multiple bathrooms. The project faced numerous challenges, including multiple complaints and violations between 2017-2020 regarding unsafe demolition practices, including unauthorized removal of walls and roofs, which were eventually resolved by March 2018.

Most recently, the building has been undergoing additional improvements, with active permits from 2023-2024 for the installation of fire sprinklers, heat pump systems, and other plumbing and electrical work. These recent permits indicate ongoing efforts to enhance the building's safety features, including a $47,245 fire sprinkler installation in 2023 and electrical work in 2024. However, there have been several concerning complaints in 2023-2024 regarding construction site management, exterior maintenance, and preservation of the building's historic facade. These complaints suggest ongoing challenges with construction oversight and building maintenance, though most recent complaints from September-October 2024 have been marked as not active. A notable current issue, as of January 2023, involved concerns about rainwater runoff and building protection during storms.

Risk rating

How 274-276 Duncan 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
13thpercentile

Out of 1879 buildings in this neighborhood, 1635 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
