Rent & eviction protection

Is 1536-1538 18Th 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 1908

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 1908
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 1536-1538 18th Street in Potrero Hill is a two-story, two-unit multi-family residential building constructed in 1908, currently owned by the McCarthy-Economy Revocable Trust. The building has undergone several significant renovations and maintenance work over the past three decades, with the most recent major improvement being the installation of a three-zone air conditioning system with heat pump and new air handlers in December 2024, representing a modern HVAC upgrade. Historical records indicate multiple roofing and window-related projects in the early 1990s, including two separate roofing permits in 1993, window replacement work in 1994, and fence repairs in 2000. The building experienced some structural and maintenance work in 1993, including drywall patching, wood floor repairs, window work, and beam replacement.

Recent issues affecting the property include a sidewalk defect reported in September 2022 involving lifted sidewalk conditions, which was resolved by the Department of Public Works. There was also a parking violation incident involving a Tesla Model 3 on the sidewalk in August 2022, though responding officers were unable to locate the vehicle. Earlier service calls include a 2014 duplicate service request to Recology for abandoned items. The property's documented maintenance history shows regular upkeep over the years, with the most recent upgrade significantly improving the building's climate control system.

Risk rating

How 1536-1538 18Th 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.
