Rent & eviction protection

Is 653-655 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.

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.

Just-cause eviction

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 2-unit, multi-family residential building at 653-655 20th Avenue in the Central Richmond neighborhood, owned by the Lui Family 2017 Trust, was constructed in 1922 and has undergone several significant modifications over its lifetime. The most substantial work occurred in 2001-2002, when a horizontal addition was constructed with an estimated cost of $80,000, along with revisions including the installation of a new rear staircase from the second floor to grade. The building also received a new roof in 1994, though that permit has since expired. More recently, there have been notable quality of life issues impacting residents. In March 2017, there was a complaint about excessively bright, possibly unpermitted, exterior lighting that reportedly illuminated neighboring bedrooms from a significant distance. The property has also experienced some maintenance challenges, including a sewage backup incident reported and resolved in January 2024. Parking-related issues near the property appear to be a recurring concern, with multiple citations issued between 2022-2024 for vehicles blocking driveways or parking on sidewalks, suggesting limited parking availability in the area. Additionally, there was a noise complaint reported in November 2023, though the specific nature of the noise was not detailed in the records.

Risk rating

How 653-655 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
93rdpercentile

Out of 2250 buildings in this neighborhood, 158 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
