San Francisco supervisors Myrna Melgar and Jackie Fielder plan to unveil a proposal Tuesday to narrow the grounds for nuisance evictions.

Under the proposed change, the conduct would have to be severe or persistent and recurring, Melgar’s office said. The measure would also give tenants a chance to address conditions before losing their homes.

The San Francisco Rent Board’s annual report, released in February, counted 405 nuisance eviction notices, a 41% increase from 288 a year earlier. More than 1,000 evictions have been filed citywide this year, putting 2026 on pace for the highest total in a decade.

At a rent-controlled Jackson Street building, landlord Nabob Hill LLC served eviction notices in March to tenants in five units, alleging dangerous clutter. The landlord later told Sue Yeng Yan, 92, that she had resolved the cited conditions and could stay. Her son-in-law, Kin Wong, said she remains worried the landlord could try to evict her again.
