Rent & eviction protection

Is 1021-1023 Washington 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
2 or more units

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 1021-1023 Washington Street in Nob Hill is a 2-story flats/duplex structure built in 1900, currently owned by Naso 2018 Tr. The property has undergone several significant improvements over the past several years, with the most recent being a heating system upgrade in October 2020 featuring a new heat pump unit. In 2019, substantial remodeling work was completed in the upper unit (#1021), including a kitchen relocation project costing over $22,000, along with corresponding plumbing and electrical upgrades. Major renovations were also performed in 2018, including the removal of two non-functioning chimneys, second-floor remodeling, window replacement, and a comprehensive electrical upgrade that installed a new 200-amp main service with three meters and sub-panels for each unit.

The building has had periodic maintenance and improvements throughout its history, including re-roofing work in 2017 ($5,000), and historical records show earlier renovations dating back to 1985 when stairs were replaced. The property has experienced recurring issues with driveway blockages, particularly in the latter half of 2024, with multiple citations issued for vehicles blocking the driveway. Two false fire alarm incidents were recorded, though neither resulted in civilian injuries. A tenant buyout occurred in April 2018 at the address 1021 Washington Street, with one tenant receiving $17,500.

Risk rating

How 1021-1023 Washington 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
79thpercentile

Out of 1125 buildings in this neighborhood, 236 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.

Building age

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

Neighborhood location

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
