Rent & eviction protection

Is 1051 De Haro 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 1911
2 or more units

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 1911
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 property at 1051 De Haro Street is a three-unit, two-story multi-family residential building located in Potrero Hill, built in 1911 and currently owned by Andrew D. Lynch. The building underwent significant renovations in 2012, including a comprehensive interior remodel of all three units, electrical upgrades, plumbing improvements, and the installation of new furnaces and water heaters. More recent construction activity raised concerns in late 2019 when there were reports of unauthorized work to convert units and use the building as group housing for students and interns, allegedly resulting in over-occupancy. This complaint followed a pattern of unit modifications, including a previously unauthorized conversion in 2017.

The building's history includes several maintenance and violation issues, particularly in 2005 when the property faced multiple housing code violations related to building maintenance, including mold, water damage, inadequate heating, and fire safety concerns. These violations were abated by October 2005. There were also multiple cancelled or withdrawn permit applications in 2012 related to foundation work, electrical upgrades, and various repairs. The property has been the subject of numerous recent parking violations in the vicinity, with multiple citations issued between 2023-2024 for vehicles parking on the sidewalk, though these are external to the building itself. Additionally, there were issues with illegal short-term rentals recorded in 2018-2019, which were ultimately resolved, including a period when the property was reportedly being used as co-op/intern group housing with 10-12 occupants.

Risk rating

How 1051 De Haro 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
5thpercentile

Out of 726 buildings in this neighborhood, 690 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
