Rent & eviction protection

Is 491-495 3Rd 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 1907

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 1907
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 491-495 Third Street is a two-story, 3-unit residential building constructed in 1907, currently owned by 493-495 Third Street LLC. The building has experienced notable issues in recent years, particularly in early 2023 when two complaints were filed regarding the penthouse unit - one concerning missing siding on penthouse stairs and another related to unauthorized construction work. These issues were addressed, with the installation of a legally permitted fire-rated exit door modification completed in January 2023.

The building's maintenance and safety record over the past seven years shows some cause for concern, with a total of 521 311 service requests recorded, though only two DBI complaints were officially filed. Recent complaints from 2026 suggest ongoing concerns with the surrounding area, including issues with large vehicles, sidewalk structure, and debris, though most of these cases were resolved or determined to be duplicates. While the most recent permit indicates proactive measures to address safety concerns, the high volume of 311 service requests suggests ongoing maintenance needs. The property has undergone significant changes in its immediate environment, particularly with the adjacent property's demolition, which required the installation of the new fire-rated exit door modification.

Risk rating

How 491-495 3Rd 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.
