Rent & eviction protection

Is 412-414 Plymouth Ave 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 1948

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 1948
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 property at 412-414 Plymouth Avenue, a two-unit residential building constructed in 1948, has undergone several significant changes and faced multiple compliance issues over the years. Most recently, in February 2022, substantial exterior improvements were completed, including new siding on the front and back of the building and window replacements, at a cost of $15,000. However, the building has experienced persistent infrastructure challenges, particularly with sewer problems, as evidenced by multiple sewage backup incidents from 2022 through 2024, including four occurrences between July and September 2024 from the side sewer vent.

The building's history reveals a pattern of unauthorized modifications and safety concerns. In 2008-2012, there were multiple attempts to address issues with a rear deck and stairs, following concerns about dry rot and safety, including an active violation filed in January 2008. Earlier violations from 2003-2005 documented unauthorized construction of a third dwelling unit in the garage, complete with illegal kitchen and bathroom facilities, and improper use of R-3 occupancy for a car repair business. The property has also been subject to various complaints regarding unpermitted construction work, including electrical wiring and sheetrock installations in 2007-2008, construction noise, and weekend work. Recent municipal records show ongoing maintenance of the building's basic systems, though with some notable concerns, such as a significant number of parking violations for blocking driveways reported between 2022 and 2024.

Risk rating

How 412-414 Plymouth Ave'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
91stpercentile

Out of 79 buildings in this neighborhood, 7 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
