Rent & eviction protection

Is 275 Grattan 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 1928

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

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 11-unit, 3-story multi-family residential building at 275 Grattan Street, owned by SF Multifamily III Property, has undergone significant renovations and faced several challenges since its construction in 1928. The property has completed extensive renovations, including the conversion of garage spaces to dwelling units, installation of a new fire sprinkler system, and comprehensive upgrades to multiple units between 2016 and 2019, with costs exceeding $300,000. Notable improvements included fire safety upgrades in 2017-2018, such as a new fire alarm system, smoke detectors, and sprinklers, though several fire-related violations were recorded between 2017-2022 related to alarm systems, extinguishers, and emergency lighting, all of which were subsequently abated.

Recent concerns have emerged regarding heating systems, with multiple complaints in January 2024 about inadequate heat, leading to violations filed under housing codes. The building's history includes various maintenance issues, including problems with plumbing (notably in 2014), mold, and debris management. A significant tenant buyout occurred in May 2019 for $30,000. While the property achieved a completed status under Tier 3 of the soft-story program, indicating seismic retrofit compliance, it continues to experience challenges with heat maintenance as of early 2024, which appears to be an ongoing concern based on recent violations and complaints. The building's recent permit history shows active maintenance and upgrading of units, with particular attention to kitchen and bathroom renovations, and the installation of new systems throughout the building.

Risk rating

How 275 Grattan 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
13thpercentile

Out of 526 buildings in this neighborhood, 458 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
