Rent & eviction protection

Is 811 Carolina 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 1911
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-unit, two-story multi-family residential building located at 811 Carolina St in Potrero Hill was constructed in 1911 and currently owned by 811 Carolina LLC. The property has undergone significant renovations and improvements over the past several years, including substantial work in 2018-2020 featuring a first-story horizontal addition, kitchen reconfigurations, and the installation of comprehensive fire safety systems with new sprinklers throughout the building and a monitoring system. Major infrastructure upgrades occurred in 2019-2020, including a rooftop heat pump installation, new plumbing systems including PEX, and electrical improvements including a rooftop PV solar system.

The building had several historical violations and complaints in the 2007-2009 period, including issues with heating systems, handrails, and plumbing concerns, though all these violations were ultimately abated by March 2009. A recent resolution regarding potential unauthorized short-term rentals was addressed, with compliance confirmed after tenant and ownership cooperation. Recent maintenance issues have primarily been related to exterior features such as tree maintenance and street cleaning, with no serious violations or complaints recorded in recent years. The most recent building improvements indicate a focus on sustainability and modern amenities, including solar power and updated fire safety systems, while recent 311 calls primarily concern general maintenance issues in the surrounding area rather than building-specific problems.

Risk rating

How 811 Carolina 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
