Rent & eviction protection

Is 449 Vermont 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.

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.

Built 1906
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 property at 449 Vermont Street is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by the Krumholz-Hata Family Trust. The building has undergone several significant improvements over its lifetime, including an interior renovation of the second-level living unit in 2004 that involved demolition of existing interior walls and ceiling joints, with associated electrical work also completed that year, costing approximately $25,000. Earlier repairs of note include work on the back stairs and stringers in 1995, though this permit is recorded as expired, and a complete reroofing project in 1989.

A concerning issue has emerged in recent years, with an active housing complaint filed in July 2018 regarding suspicions of an illegal unit due to the absence of a number on the tenant's door. The property is currently experiencing significant external challenges, as evidenced by numerous encampment-related 311 calls between March and September 2024, with multiple reports logged between May and July 2024 alone, though most calls have been marked as unable to locate or closed with various notations. A separate incident involving graffiti was reported and resolved in March 2023. The building's most recent permitted work was completed in 2004, and there have been no major permitted improvements or repairs on record in the past two decades, which may be worth noting given the building's age.

Risk rating

How 449 Vermont 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
72ndpercentile

Out of 726 buildings in this neighborhood, 203 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
