Rent & eviction protection

Is 52 Sanchez 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
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 12-unit, 4-story multi-family residential building at 52 Sanchez Street in Duboce Triangle, owned by Dere Investment Associates, has undergone several significant upgrades and faced various challenges since its construction in 1907. Most notably, the building completed mandatory soft-story seismic upgrades in 2016-2017, involving additional footings and structure reinforcement, achieving "Work Complete, CFC Issued" status as a Tier 4 property. A major fire incident in 2004 required comprehensive repairs including kitchen and bathroom replacements, roof work, and electrical system rewiring, costing approximately $300,000. More recently, in 2022, the building received a new hydronic boiler installation, and various fire safety improvements have been made, including a 2023 correction of combustible materials issues and previous violations in 2019 regarding alarm systems and extinguishers.

The building's history includes a series of routine inspections and some concerning incidents in the early 2000s, particularly multiple violations related to fire safety, smoke detection, and building maintenance in August-October 2002, all of which were subsequently abated. Electrical system upgrades were performed in 2004-2005, including rewiring of multiple units and kitchen installations. Recent housing inspections in 2016 and 2023, though not revealing any ongoing concerns, indicate regular oversight of building conditions. The property has maintained relatively active response to fire safety issues, with various violations being promptly addressed through repairs or corrections, including a significant focus on maintaining fire alarm systems and extinguishers. The building's recent history shows ongoing maintenance and upgrading of essential systems, though there have been occasional issues requiring correction, such as a 2023 combustible materials complaint and previous fire alarm system concerns.

Risk rating

How 52 Sanchez 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
17thpercentile

Out of 287 buildings in this neighborhood, 238 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
