Rent & eviction protection

Is 1263-1265 20Th Ave 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 1911

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 1911
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 property at 1263-1265 20th Avenue is a 2-story mixed-use building constructed in 1911, containing 3 residential units and commercial space, owned by Paul Ming Kuan and Hsiu-Ting Do. The building underwent significant renovations in 2006-2007, including a major interior remodel that added bathrooms and laundry facilities, relocated plumbing and kitchen features, and improved exterior siding. This renovation was accompanied by comprehensive electrical upgrades, including the installation of new service panels and wiring. A notable incident occurred in 2007 when unauthorized plumbing work in the commercial space resulted in a violation that was resolved within four months. The property has experienced various maintenance issues over the years, including multiple instances of roof work in 1993 and 2000, and a fire incident in 1989 requiring first-story repairs.

Recent history shows some community concern about unauthorized uses, such as a 2013 complaint regarding an alleged illegal conversion from apartment to hotel with unauthorized kitchen installation, though this complaint was marked as not active. The building and surrounding area have experienced several maintenance-related issues over the past decade, with multiple reports of garbage and debris on the street between 2015 and 2024, though all these issues were eventually resolved. There have also been periodic issues with graffiti, including a notable incident in 2020. The most recent building-related complaints have been primarily focused on exterior maintenance and street cleanliness rather than structural or safety concerns within the building itself.

Risk rating

How 1263-1265 20Th Ave'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
9thpercentile

Out of 814 buildings in this neighborhood, 741 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Property class: apartment building

Apartment building — this property classification influences expected violation rates.
