Rent & eviction protection

Is 4441-4443 20Th 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.

15+ years since occupancy
Built 1906
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

Located in the Eureka Valley/Dolores Heights neighborhood, this two-unit residential building at 4441-4443 20th Street is a two-story flats and duplex structure built in 1906, currently owned by George Lester King Ii Revoc. The property has undergone several significant improvements over the years, with the most recent notable work in 2016 including the installation of a kitchen range fan vent system and a new gas fireplace with associated gas line work costing approximately $1,620. Prior major renovations occurred in 2007, when both units received kitchen and bathroom remodels, along with electrical system upgrades including a new 200-amp service installation and sub-panelboard, costing $35,000. Building maintenance history shows attention to structural integrity, with documented repairs of dry rot issues in 1995-1996 and a reroofing project completed in 1996.

The property has experienced multiple parking-related issues in recent years, with five documented incidents between 2022 and 2024 involving vehicles blocking driveways or parking on sidewalks, though enforcement officers were often unable to locate the offending vehicles. Infrastructure concerns have been noted, including a pavement defect reported in October 2024 and a curb defect identified in August 2020 that remains unresolved as of this writing. Earlier neighborhood issues included incidents of offensive graffiti on utility poles in 2016, which were subsequently addressed. The building's documented permit history suggests regular maintenance and upgrading of systems, with particular attention paid to kitchen and bathroom facilities in both units, though no major structural or safety concerns have been recorded in recent years.

Risk rating

How 4441-4443 20Th 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
61stpercentile

Out of 1278 buildings in this neighborhood, 498 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.

Building permits, owner's portfolio

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