Rent & eviction protection

Is 66-68 Winfield 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.

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 66-68 Winfield Street in Bernal Heights, owned by Sunhee Moon Lvg Tr, is a two-story flat/duplex structure built in 1900. Recent records show significant plumbing issues in 2024, with multiple sewage backup incidents from the side sewer vent reported between July and December 2024, indicating ongoing sanitation infrastructure challenges. The property underwent several maintenance actions in 2022, including compliance work based on inspection report CC-8571 and interior modifications in Unit 66 involving basement wall removal and wet bar modifications, all at a cost of $5,000. Historical maintenance records include reroofing work completed in 2008 ($2,500), a window replacement project in 2002, and administrative actions in 2009 to clearly define the addresses for both units. The property has also experienced recent environmental impacts, with reports of tree root damage to property and sidewalk in July 2023 that remains open. Parking-related issues have been documented, including multiple reports of driveways being blocked in late 2024, though these are not structural concerns. The building underwent a condo conversion process in 2023, which has been marked as approved in planning records.

Risk rating

How 66-68 Winfield 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
80thpercentile

Out of 1276 buildings in this neighborhood, 255 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.
