Rent & eviction protection

Is 645-647 Chestnut 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 1900

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 1900
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 multi-family residential building at 645-647 Chestnut Street in the North Beach neighborhood, owned by the Paul Lebaron Thiebaud Trust, was built in 1900 and consists of two stories plus a retail space. The property has experienced significant fire safety issues over the past two years, with multiple violations and complaints between 2022 and 2024 related to alarm systems, sprinkler systems, hazardous materials, and sleeping area requirements, though most of these conditions were generally corrected once cited, with one current violation remaining as of December 2024 regarding the alarm system and a prior violation concerning sleeping area requirements from November 2023. The building's recent permit activity includes a substantial accessibility improvement project in 2024 with a budget of $11,225 to replace thresholds and improve doorway access in compliance with city ordinances.

The property has had a series of fire alarm system activations and elevator rescue incidents throughout its history, with the most recent fire-related violations and complaints occurring in 2023-2024. The building's recent maintenance record shows the owner is actively addressing accessibility improvements, with a significant permit filed in August 2024 for doorway modifications. The property has experienced some neighborhood issues in early 2025, with multiple reports of encampments and debris on the surrounding sidewalks, though these are external to the building itself. A series of street space permits were issued between 2009-2010, and a horizontal addition was completed in 1989, indicating the building has undergone various modifications and improvements over its long history.

Risk rating

How 645-647 Chestnut 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
87thpercentile

Out of 362 buildings in this neighborhood, 47 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
