Rent & eviction protection

Is 4320-4322 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 1948

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.

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 Kwan Jim & Julia C H & Kwan-owned duplex property at 4320-4322 Balboa Street in the Outer Richmond has undergone several significant improvements since its construction in 1948. Most notably, in 2015, the building received substantial upgrades including the replacement of 11 windows, complete remodels of two bathrooms and kitchens, and significant electrical, plumbing, and mechanical improvements, with a total investment of $85,000. This work was followed by a complete re-roofing project in 2016 costing $11,500.

The property has experienced recurring sewer-related issues, with multiple sewage backup incidents reported through 311 calls between 2012 and 2019, though these have typically been promptly addressed. A notable incident occurred in December 2016 involving marble cutting on the sidewalk that generated dust concerns, though this complaint is now listed as not active. Recent maintenance issues include reports of overgrown trees (May 2024) and electrical infrastructure concerns (May 2022), indicating ongoing attention to exterior conditions. The building's major systems have received documented upgrades, including installation of new furnaces, water heaters, laundry sinks, and electrical improvements featuring comprehensive updates to lighting, switches, receptacles, and smoke detectors, with a 200-amp service upgrade in 2015. While there have been several graffiti incidents reported (most recently in 2021), these have been promptly addressed by city services.

Risk rating

How 4320-4322 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
44thpercentile

Out of 1040 buildings in this neighborhood, 582 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
