Rent & eviction protection

Is 1301 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.

Built 1910

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

The 1301 California Street building, a 3-story, 21-unit residential property built in 1910 and currently owned by Acd Investments Lp, has experienced significant recent challenges, particularly regarding its heating system and maintenance compliance. As of November 2024, there are multiple active violations, including issues with the building's heating system that no longer meets current San Francisco heat ordinance requirements, and concerns about peeling and deteriorated paint on exterior surfaces. Of particular note, there have been recurring problems with the heating system, with tenants reporting lack of heat in winter months (as recently as December 2025) and concerns about inadequate temperature maintenance.

The building has undergone recent repairs and improvements, particularly following fire damage to units 18 and 19 in April 2026, which prompted multiple permit applications for kitchen and bathroom remodels as well as electrical system upgrades. Structural work has also been documented, including foundation and retaining wall repairs in 2024. The property has a significant history of complaints and service requests, with 793 311 service requests and 16 Department of Building Inspection (DBI) complaints recorded over the past seven years, though many of these appear to be routine maintenance issues. The building currently requires several compliance affidavits, including a smoke/carbon monoxide alarm affidavit and a Section 604 exterior building components inspection affidavit, indicating ongoing regulatory compliance challenges.

Risk rating

How 1301 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.

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
25thpercentile

Out of 448 buildings in this neighborhood, 336 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
