Rent & eviction protection

Is 18 Cadell Pl 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.

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.

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 18 Cadell Place is a three-story multi-family residential building with 4 units, constructed in 1892, and currently owned by the Ong Suey Won Trust. The building has undergone several significant renovations and maintenance work in recent years, with notable window and door replacements in 2016, including the installation of new sliding doors and windows on multiple floors, along with exterior deck surface replacements. The building's maintenance history shows consistent upkeep, with fire safety improvements made in 1991 including sprinkler installation in the basement.

The property has experienced multiple fire safety-related incidents, including a cluster of violations in November 2005 that were promptly addressed by December 2005, concerning garage floor storage, gas utility shutoff tools, gas meter instructions, and fire extinguisher maintenance. More recent fire complaints were recorded in 2018 and 2021, though the 2018 complaint was found to have no merit. While there have been several fire alarms recorded (mostly false alarms or system malfunctions), no civilian injuries have been reported in any incidents. Recent 311 calls from 2024 primarily relate to noise and sanitation issues in the surrounding area, including complaints about garbage, debris, and noise disturbances, which appear to be environmental rather than building-specific issues. The building has maintained compliance with housing inspections, with routine inspections conducted in 2005 and 2010 showing no ongoing concerns.

Risk rating

How 18 Cadell Pl'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
