Rent & eviction protection

Is 848-850 Church 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 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 two-unit residential building at 848-850 Church Street is a 2-story flats and duplex structure built in 1900, currently owned by Irene A. Fan. The property has undergone several significant improvements and faced a major incident in its recent history. In December 2003, the building experienced a fire that resulted in substantial electrical work, including the removal of knob and tube wiring and the installation of new electrical panels and circuits throughout the property. Two notable solar installations were completed in June 2015, featuring 13 roof-mounted solar PV modules each with 315 watts capacity, contributing to the building's sustainability profile.

In October 2018, building modifications sparked some regulatory attention, resulting in a Notice of Violation for unauthorized work including a roof deck installation and new rustic wood siding on the garage area. The violation was resolved within six days, though it was accompanied by multiple permit filings (including a $21,000 garage renovation project) and compliance measures. Recent maintenance history shows active management of the property, with the most notable recent events being infrastructure work in 2018 and the successful solar installations in 2015. The building's location has experienced typical urban issues, as evidenced by multiple 311 calls between 2022 and 2023, primarily related to street maintenance, cleaning, and a couple of flooding incidents in 2022, though these are external to the building itself. The property appears to be actively maintained, with all recent permits and complaints showing proper resolution through appropriate channels, and no current active violations on record.

Risk rating

How 848-850 Church 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
64thpercentile

Out of 1278 buildings in this neighborhood, 460 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
