Rent & eviction protection

Is 28-30 Santa Marina 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 1977

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 two-unit residential building at 28-30 Santa Marina Street in Bernal Heights, owned by Ohara Joy Masako, is a two-story flats and duplex structure built in 1977. The property has undergone numerous significant improvements over the past several years, with the most recent major work being an $80,000 re-roofing project and new roof deck construction permitted in April 2024, along with the installation of new outdoor deck roof outlets planned for late 2024. Between 2018-2019, the building underwent substantial renovations including multiple bathroom and kitchen remodels, deck constructions, and the installation of laundry facilities. These improvements were comprehensive, addressing both aesthetic and functional aspects, including electrical upgrades to 100-amp service, installation of new fixtures, and replacement of sliding doors.

The building's maintenance history shows regular upkeep, with earlier records indicating a roof replacement in 1991. The property's infrastructure improvements have been accompanied by appropriate permits for plumbing and electrical work, ensuring compliance with building codes. While there have been several 311 calls regarding the property's vicinity between 2015 and 2024, these primarily concerned external issues such as street pavement, flooding, and parking violations, rather than problems with the building itself. The most recent building permits and planning records demonstrate ongoing investment in maintaining and upgrading the property, with all work being properly permitted and subject to review, including the recent approval for a new roof deck that maintains required setbacks and safety standards.

Risk rating

How 28-30 Santa Marina 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
56thpercentile

Out of 1276 buildings in this neighborhood, 561 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
