Rent & eviction protection

Is 840 Barneveld Ave 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 1900
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 1900
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 840 Barneveld Avenue in the Portola neighborhood is a two-story flats and duplex structure built in 1900, currently owned by Myrtle M E King. The property has a documented history of unauthorized construction, with a significant complaint filed in January 2016 regarding an unpermitted 300-square-foot rear addition. This violation, related to code sections 102A.3 and 103A, was formally noticed by the Building Inspection Division on January 11, 2016. An earlier incident from June 2004 involved an unpermitted basement unit, though this complaint was quickly resolved within four days.

More recently, the property has generated numerous 311 calls throughout late 2024 and early 2025, predominantly related to parking enforcement issues. Between December 1, 2024, and January 14, 2025, there were eight parking-related complaints, with at least two resulting in citations. The area also experienced multiple incidents of garbage and debris complaints in early January 2025, including reports of Christmas trees and other loose debris that were subsequently resolved by Recology. The frequency of these recent service calls, particularly the parking enforcement issues, suggests ongoing challenges with on-street parking management in the vicinity of the property.

Risk rating

How 840 Barneveld Ave'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
58thpercentile

Out of 255 buildings in this neighborhood, 107 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
