Rent & eviction protection

Is 1721-1723 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 1946

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 two-family residential building at 1721-1723 Greenwich Street in Cow Hollow, owned by Nicholas T Jr & Linda Neel, was constructed in 1946 and stands two stories tall. The property has undergone several significant improvements over the years, with the most recent major work being the installation of two new furnaces in the garage in May 2021. In 2010, the building received updated street-facing windows, with eight wood paintable fiberglass units installed at a cost of $12,500. Earlier improvements include an attempted office space addition in 2003 (permit expired), electrical work in 2005, and multiple roofing projects, with the most recent completed in 2002 costing $7,500. The electrical system received an upgrade in 2004 to 200 amps, though this permit eventually expired.

The building's maintenance history shows regular attention to infrastructure, particularly windows and roofing, with earlier permits indicating the installation of aluminum windows in 1985. Recent activity on the street has primarily involved parking enforcement, with multiple citations issued for driveway blocking between 2020 and 2023. There have been several 311 calls for street maintenance, including garbage removal in 2021 and 2024, though these were external to the building itself. A fire incident was recorded at the property, classified as an "other" type fire with unintentional ignition, though no civilian injuries were reported. The property has maintained its classification as a flats and duplex building throughout its history, with a total of two residential units.

Risk rating

How 1721-1723 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
88thpercentile

Out of 861 buildings in this neighborhood, 103 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
