Rent & eviction protection

Is 1119-1123 Folsom 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 1910
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 1119-1123 Folsom Street is a two-story, three-unit commercial building constructed in 1910 and currently owned by Golden Properties LLC. The building has experienced significant activity over the past several years, with 424 311 service requests, two Department of Building Inspection (DBI) complaints, and two fire incidents reported in the last seven years. The most concerning recent events involve two DBI complaints from late 2024 regarding unauthorized construction work, including electrical work and remodels, as well as potentially serious structural issues involving demolition. These complaints were subsequently abated between March and July 2025.

In early 2025, a building permit was issued for interior improvements, including the removal of existing kitchen facilities, installation of new non-load bearing partitions, and updates to accessibility features and property line openings. The permit represents a legitimate attempt to address some of the earlier unauthorized work. The property has also been the subject of numerous 311 service requests in 2026, including multiple reports of garbage and debris issues, and several incidents related to entertainment activities, which were investigated and found to be compliant with permit conditions. Additionally, there have been several homelessness-related service requests in the vicinity, though these appear to be external to the building itself.

Risk rating

How 1119-1123 Folsom 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.
