Rent & eviction protection

Is 1670-1672 Greenwich 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 1947
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1947
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 multi-family residential building at 1670-1672 Greenwich Street in Cow Hollow, currently owned by High Holborn Floor 7 LLC, has undergone significant renovations since 2013. The substantial 2013-2014 renovation, valued at approximately $493,000, transformed the property by redistributing units, merging upper stories, adding a fourth story with a new roof deck, and installing modern amenities including two kitchens and five and a half bathrooms. This project also included important safety upgrades such as a comprehensive sprinkler system installation in 2014 ($15,000) and the continuation of an elevator to the fourth floor. The building's infrastructure improvements are notable, featuring hydronic heat systems, radiant heating, and extensive electrical upgrades including the installation of a Tesla wall connector in 2017 and a residential elevator in 2015.

The property has maintained reasonable upkeep since the major renovations, with the most recent relevant maintenance being a noise complaint in April 2024. While there was a historical complaint regarding an illegal unit (2011) which remains marked as not active, there have been no confirmed violations or serious safety concerns on record. Regular maintenance items have included window replacements in 2007 and stair repairs in 1997 (though this permit expired). The building's immediate area has experienced typical urban issues as evidenced by 311 calls between 2021-2024, primarily relating to street cleaning and sidewalk maintenance, with the most concerning issues being some hazardous materials (open case from February 2023). However, these external matters do not directly reflect on the building's condition or management.

Risk rating

How 1670-1672 Greenwich 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
