Rent & eviction protection

Is 716-720 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 1928

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 1928
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 4-unit, 2-story multi-family residential building at 716-720 20th Avenue in the Central Richmond neighborhood, constructed in 1928, has experienced several significant maintenance and compliance issues in recent years. Most concerning is a July 2023 complaint regarding possible mold and mildew issues following a large water leak, with residents reporting health concerns and building damage. In 2022, the building underwent plumbing upgrades including the installation of a tankless water heater and p-trap replacement, but experienced multiple violations and complaints related to water damage, plumbing, and appliance issues. These violations were primarily addressed by October 2022, but included concerns about water damage, a malfunctioning stove, and the need for proper water heater installation.

The building's maintenance history shows periodic attention to basic upkeep, including window replacements in 2009, reroofing in 1997, and compliance with various building codes. Significant historical violations include a 2003 case involving egress obstruction and fire proofing repair requirements, and a 2014 case regarding guardrail repairs and structural maintenance affidavit completion. More recent maintenance issues have included concerns about a large water heater's placement, stove malfunction, and electrical problems, all of which were addressed through permits and repairs, though some residents noted persistent concerns about various building systems. Historical records also indicate past challenges with noise transmission, possible pest issues in 2020, and routine inspections revealing various code compliance matters that have generally been resolved through appropriate permitting and repairs.

Risk rating

How 716-720 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
