Rent & eviction protection

Is 106 Webster 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.

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

106 Webster St is a two-unit multi-family residential building located in Hayes Valley, built in 1886 and owned by Raul & Denise Arriaza. The property has undergone several significant improvements over the years, with the most recent being a kitchen renovation in 2019 costing $8,000, which included cabinet replacements and countertop upgrades. In 2004-2005, the building experienced a series of urgent maintenance issues that required attention, including problems with a dilapidated guardrail at the walkway (which was ultimately addressed through a permit in 2004), and multiple violations related to sewer gas concerns from corroded piping that required abatement. The building also had work completed in the mid-1990s, including kitchen cabinet replacement, wood rot repairs, reroofing, and structural repairs to front stairs.

Recent fire incident records show only minor incidents, including one contained cooking fire and several false alarms, none involving civilian injuries. The property has generated multiple 311 calls between 2014 and 2022, primarily related to street and sidewalk cleaning needs, with some concerning tree maintenance and general cleaning issues outside the building. There were certain compliance issues in 2004 related to permits and inspections that required additional attention. While there is one active complaint from 1995 regarding an allegedly illegal rental unit, most historical complaints and violations have been resolved.

Risk rating

How 106 Webster 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
