Potrero Hill, SF 94107 4160062 4 units · 3 fl · 1914

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1017 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 1914
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.

Built 1914
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

1017 De Haro Street is a 3-story, 4-unit multi-family residential building constructed in 1914 in the Potrero Hill neighborhood, currently owned by Peter Michaelian. The property has undergone several significant renovation projects over the years, with the most recent major work focusing on the laundry area in 2019, involving excavation, retaining wall construction, and structural beam installations, all valued at approximately $30,500. This followed an earlier attempt to address similar issues in 2013 that was ultimately cancelled. The building has a history of maintenance and safety concerns, particularly evident during 2019 when multiple violations were recorded, including issues with smoke detectors, structural maintenance documentation, weatherproofing on exterior siding, and common area access, though these were all abated by March 2019. Earlier violations from 2004 had documented issues with plumbing, electrical systems, fire safety, and gas utility shutoff tools, while a 2010 inspection highlighted the need for seismic bracing on the water heater and fire extinguisher requirements, all of which were subsequently resolved.

Historical records show roofing work was completed in both 2000 and 2012, and a kitchen remodeling project was attempted in 1991. The building has experienced several tenant comfort issues over the years, including reports of heating problems in 2006 and window functionality concerns in 2007. Recent years have seen relatively few internal building issues reported through 311 calls, with most recent complaints in 2020-2023 focusing on external issues like parking violations, sidewalk obstruction, and abandoned vehicles near the property. The most recent building-related service request was filed in November 2023 regarding hazardous materials. A noteworthy event in the building's history is a tenant buyout at a nearby address (1025 De Haro Street) in 2018 involving three tenants for $40,000. The most recent construction work on record was related to interior excavation for the laundry room, though this work was the subject of a complaint about unpermitted demolition activities in March 2019.

Risk rating

How 1017 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
33rdpercentile

Out of 726 buildings in this neighborhood, 486 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
