Rent & eviction protection

Is 571 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 1907

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 1907
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-unit residential building at 571 Greenwich Street in Telegraph Hill is a two-story flats and duplex structure built in 1907, currently owned by Yet Koon & Choi Ying Woo Lv. The property has undergone several notable events in recent years, with the most recent being voluntary basement strengthening work completed in May 2024, involving the addition of 1/2" plywood sheathing to the perimeter walls at a cost of $10,000. However, there have been significant concerns regarding recent construction activities; in April 2024, a complaint was filed about unpermitted construction work involving loud banging and drilling, and in August 2024, another complaint was lodged regarding improper handling of old paint removal, with concerns about dust migration affecting windows and shared spaces. The building's service history also includes two street cleaning incidents in 2018 and 2019, which were unrelated to the building's condition or maintenance. While the recent basement strengthening work demonstrates some attention to building improvements, the pattern of construction-related complaints in 2024 raises concerns about proper permitting and safety protocols being followed at the property.

Risk rating

How 571 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
32ndpercentile

Out of 684 buildings in this neighborhood, 465 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
