Rent & eviction protection

Is 125 3Rd 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 1964
2 or more units
6 units
Property type
Multi-Family Residential
Zoning
RH2
Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1964
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 6-unit, 2-story multi-family residential building at 125 3rd Avenue, owned by Trieu Kevin Thien & Luu Tri, was constructed in 1964 and has undergone several significant improvements over the past decades. Most recently, the building addressed critical safety upgrades with the installation of low-frequency sounders in bedrooms (completed 2022) and a comprehensive fire alarm system upgrade (2022) to comply with San Francisco Fire Code requirements. The building completed a substantial first floor renovation in 2021 valued at approximately $1.41 million, which included updates to the lobby, lounge, reception, and bar areas. A mandatory soft-story retrofit was successfully completed in 2017 (at a cost of $90,000), bringing the building into compliance with San Francisco's seismic safety requirements.

The property has experienced some maintenance challenges over the years, with recent issues including multiple sewage backup incidents in late 2023 (November), potentially indicating ongoing plumbing infrastructure concerns. Historical violations from 2004 raised concerns about emergency exits, smoke detectors, and emergency lighting, though these were resolved. More recent complaints from 2013-2014 highlighted various maintenance issues including heating problems, ventilation deficiencies, and plumbing concerns, all of which were subsequently addressed. The building's systems have received periodic upgrades, including electrical panel replacements in 2022 and multiple unit-specific repairs through the years. While the property has maintained compliance with major regulatory requirements (including soft-story retrofit completion), recent 311 calls regarding tree root damage to infrastructure and recurring sewage issues suggest some persistent maintenance challenges.

Risk rating

How 125 3Rd 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
