Rent & eviction protection

Is 660-662 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 1940

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 1940
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 660-662 De Haro Street in Potrero Hill, owned by Bradrick Ajwani Fmly Tr, is a two-story, two-unit multi-family residential building constructed in 1940. The building has undergone significant recent renovations, with major work completed in 2020 following two substantial permit approvals from 2019-2020 totaling over $750,000 in improvements. These renovations included excavation for new patios, extensive interior remodeling of both units, addition of a roof deck, new energy-efficient windows, and comprehensive updates to electrical and plumbing systems throughout both units, including radiant heating installation and a 200-amp electrical service upgrade.

The building has a documented history of fire safety violations, with multiple citations issued between 2019 and 2024, including concerns about sprinkler systems, emergency lighting, exit reliability, and smoke alarms. These violations have generally been marked as abated, though some recent violations from September 2023 regarding sprinkler testing and maintenance, emergency lighting, and gas container security were referred to hearing. The property underwent substantial construction work in 2020, which generated several building complaints regarding construction practices and debris management, though these complaints are no longer active. More recently, there have been multiple 311 calls in 2024 regarding garbage and debris, illegal parking, and one open noise complaint, suggesting some ongoing management or logistical challenges. The building's infrastructure improvements include modern systems such as a multi-zone mini-split system installed in 2022 and comprehensive electrical upgrades completed in 2020, indicating significant modernization of the building's systems.

Risk rating

How 660-662 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
25thpercentile

Out of 726 buildings in this neighborhood, 544 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
