Rent & eviction protection

Is 6146-6148 California 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 1909
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

This two-story multi-family residential building, located at 6146-6148 California Street in the Lake -- The Presidio neighborhood, was constructed in 1909 and contains three units plus a commercial space. The property has undergone several significant maintenance and improvement projects over the past couple of decades, with the most recent major work occurring in 2014, when multiple updates were completed including a kitchen remodel, water heater upgrades, window replacements, and electrical system improvements. The building has experienced recurring maintenance issues, particularly regarding water damage and drainage problems. Most notably, in early 2024, the property was cited for inadequate roof drainage and gutter issues, which were reportedly causing water problems for neighboring properties and were associated with rodent infestation concerns. This violation, filed in January 2024, was documented as being abated by April 2024.

Throughout its history, the building has faced various maintenance challenges, including water damage repairs, dry rot issues, and plumbing problems. A significant complaint from March 2017 reported multiple maintenance issues affecting habitability, including broken bathtub drainage, leaking windows, wall damage, kitchen sink overflow, and concerns about old carpet affecting a tenant with asthma. The property has also experienced regular upkeep work such as window replacements, roof maintenance, and awning installations, with some permits for work being canceled or expired over the years. Recent 311 calls regarding the property have primarily focused on external issues such as sidewalk cleaning and debris, with reports dating from 2016 through 2024, though these are not necessarily indicative of building maintenance problems.

Risk rating

How 6146-6148 California 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.

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.
