Rent & eviction protection

Is 1463 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 1946
2 or more units
2 units
Property type

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 1946
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, two-story multi-family residential building at 1463 20th Avenue in the Central Sunset neighborhood has undergone several significant improvements and faced some notable issues since its construction in 1946. Most recently, in August 2024, there was a completed project to replace four street-facing windows on the second and third floors with approved fiberglass materials, though this work generated at least one complaint about unpermitted remodeling and noisy construction. In September 2023, an electrical upgrade was completed with the installation of a 60-amp house meter and sub-panel, and in 2012, the gas line was repaired. The building has a documented history of parking-related concerns in the immediate vicinity, with multiple citations issued between 2022-2024 for vehicles blocking driveways and parking on sidewalks, though these issues pertain to street management rather than building conditions. Earlier building history shows a completed framing replacement in 1985 and an expired permit from 1986 for a proposed three-story addition, along with some 1992 building permit activity. The property has also maintained compliance with general maintenance requirements, as indicated by the resolution of various 311 calls related to street cleaning and illegal postings.

Risk rating

How 1463 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
70thpercentile

Out of 814 buildings in this neighborhood, 244 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
