Rent & eviction protection

Is 28-30 Hemway Ter 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 1922
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 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-story multi-family residential building at 28-30 Hemway Terrace in Lone Mountain, owned by Ock S & Po L C Wong Fmly Tr, is a two-unit structure built in 1922 and classified as Flats & Duplex. The most significant recent improvements to the property occurred in 2009 when major remodeling work was completed on the kitchen, 1.5 bathrooms, and living room, including the installation of new electrical systems with multiple fixtures and appliances, and garage modifications - all properly permitted at a cost of $34,000. The building has faced several maintenance and compliance issues over its history, including a kitchen sink and gas stove removal in 1992 and an attempted compliance improvement in 1983, though records indicate the 1983 permit was cancelled.

The property has experienced numerous sidewalk-related parking violations in recent months, particularly in 2024, with multiple citations issued for vehicles parking on the sidewalk. A notable cluster of these violations occurred between March and April 2024, involving various vehicles. More recent concerns include a building complaint filed in September 2024 regarding permit verification and sidewalk restoration, along with other infrastructure-related issues such as a damaged tree report in February 2024 and a missing street cleaning sign reported in November 2023. The building's permit history shows that all major renovation work from 2009 was properly completed and received appropriate plumbing and electrical permits, suggesting that the most significant structural improvements have been adequately documented and executed.

Risk rating

How 28-30 Hemway Ter'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
38thpercentile
