Rent & eviction protection

Is 3145-3147 Balboa 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.

Built before 1979
Built 1955
2 or more units

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 1955
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 residential building at 3145-3147 Balboa Street in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1955, currently owned by Mackey Christian & Leung Ju. The property has undergone several significant improvements over the past decade, with the most recent major renovation taking place in 2018, which included the addition of a half-bath and game room on the first floor, along with the replacement of two rear vinyl windows and a patio door, with a total project cost of $42,000. Prior to that, in 2015, substantial updates were completed to the building, including kitchen and bathroom remodeling ($23,000), electrical upgrades with the installation of a new 100-amp panel in the owner unit, and various new fixtures, appliances, and three smoke detectors. The building's maintenance and improvement records show regular attention to infrastructure, with plumbing systems receiving upgrades as needed, including the installation of the new half-bath in 2018.

The property's external environment and street-facing areas have experienced typical urban challenges, with several 311 calls recorded between 2017 and 2023, primarily relating to street and sidewalk cleaning, loose garbage, illegal postings, and noise complaints. Notably, two excessive noise reports were filed in July 2019, and there were two instances of street cleaning issues reported in 2021 and 2023, all of which were resolved through normal city processes. While these incidents reflect typical urban neighborhood concerns, none appear to indicate any structural or safety issues with the building itself. The property's permit and improvement history suggests regular maintenance and upgrading of both the interior and exterior spaces, with particular attention paid to improving resident amenities and building systems over the past decade.

Risk rating

How 3145-3147 Balboa 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
84thpercentile

Out of 1040 buildings in this neighborhood, 166 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
