Rent & eviction protection

Is 423-429 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.

Built before 1979
Built 1906
2 or more units

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 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 two-story, four-unit multi-family residential building at 423-429 Vermont Street in Potrero Hill, owned by Kanjee-khoja Amyn, was constructed in 1906 and classified as a TIC building with four units or less. The most recent significant improvement to the building occurred in July 2024, with the installation of a Mitsubishi dual-zone air conditioner heat pump system, representing the latest modernization effort. The building underwent substantial renovations in 2008, including the replacement of windows throughout the building ($15,500), installation of electric heaters in all units ($10,000) to comply with Title 24 requirements, and various plumbing upgrades including shower pan installations, new flues for water heaters, and fireplace installations. Earlier improvements in 2007 included a complete renovation of drain and vent systems for bathrooms and kitchens, along with substantial electrical upgrades including a new 200-amp panel and installation of multiple circuits, lights, and switches.

The building had two routine housing inspections, one in 2003 and another in 2008, both of which resulted in identified violations that were subsequently abated. The 2003 inspection noted lead paint concerns that were resolved by 2005, while the 2008 inspection identified several safety issues including the need for self-closing doors, gas utility shutoff tools, fire extinguishers, and gas meter instructional diagrams, all of which were abated by May 2009. Recent activity around the building, primarily in 2024, has involved multiple reports of encampments and graffiti in the vicinity, though these are external to the building itself and generally relate to street and sidewalk conditions rather than building maintenance or safety. One fire alarm system activation was recorded with no actual fire or injuries involved. The building's permit history shows regular maintenance and upgrading of systems, with all known violations having been resolved in a timely manner according to available records.

Risk rating

How 423-429 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
52ndpercentile

Out of 726 buildings in this neighborhood, 348 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
