Rent & eviction protection

Is 2434-2438 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.

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.

Built 1922
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 three-unit multi-family residential building at 2434-2438 Balboa Street in the Central Richmond neighborhood, owned by the Yamasaki Revocable Trust, was constructed in 1922 as a two-story flats and duplex structure. The property underwent significant renovations in mid-2006, with approximately $37,000 in permitted work including comprehensive bathroom remodels, kitchen improvements on the 2nd and 3rd floors, and crucial system updates including the replacement of two furnaces and three water heaters on the ground floor. This renovation also included extensive electrical upgrades, with the installation of new lighting, switches, receptacles, and the upgrading of electrical service to 200 amps with new circuit breaker panels for all three units.

The building's maintenance and compliance history shows attention to safety concerns, particularly in 2003 when the property was subject to fire safety violations related to combustible storage, which were promptly abated within approximately one month. Routine inspections of the property have generally shown either no apparent violations or been marked as "Not Active." More recent service issues have primarily involved sewer-related problems, with documented incidents in 2021 and 2022, suggesting ongoing infrastructure challenges in this area. Additionally, there have been multiple reports of sidewalk parking violations in recent years (2019-2020), though these are not directly related to building conditions or safety. The most recent building-related issue was reported in July 2024 regarding improper postings, though this was closed due to insufficient information.

Risk rating

How 2434-2438 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
28thpercentile

Out of 2250 buildings in this neighborhood, 1620 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location
