Rent & eviction protection

Is 31-33 Dearborn 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 1900

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.

15+ years since occupancy
Built 1900
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 31-33 Dearborn Street is a 2-story, 4-unit multi-family residential building located in Mission Dolores, constructed in 1900 and currently owned by Real Equity Group One LLC. The building has undergone several notable improvements and faced various compliance issues over the years. Most recently, in April 2024, the building received facade upgrades as the shingles were replaced with stucco over approximately 600 square feet, a project completed at a cost of $8,500. A significant renovation complaint was filed in September 2019 regarding unauthorized demolition work, though this was marked as not active. Historical records show multiple routine inspections between 2002 and 2008, during which various violations were noted and subsequently abated by December 2006, including issues related to smoke detectors, seismic bracing of hot water heaters, interior walls, weatherproofing, and potential lead paint hazards.

The building's maintenance history reveals several infrastructure improvements, including reroofing completed in 1995, vinyl siding replacement in 1991, and sidewalk repairs in 2004. A major proposed expansion in 2015 to add three new dwelling units was cancelled, though a variance application to convert an existing garage into additional dwelling units was ultimately approved. There have been persistent parking enforcement issues in the vicinity, with multiple 311 calls in 2022-2024 regarding driveway blockages, resulting in several citations being issued. Recent calls in September 2024 also reported issues with garbage and debris, including human waste or urine on the property. The building appears to have received regular attention to address safety concerns, with all documented violations being resolved, though the presence of recurring parking and street cleanliness issues nearby may affect resident convenience.

Risk rating

How 31-33 Dearborn 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
27thpercentile

Out of 799 buildings in this neighborhood, 583 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
