Rent & eviction protection

Is 536-538 Duncan 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.

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 1924
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 536-538 Duncan Street is a four-story multi-family residential building in Noe Valley, containing two units and built in 1924, currently owned by the Patrick J Figley Trust. The building has undergone significant renovations and additions over the past several decades, with major work occurring between 2006-2015. This included a substantial 2007 project comprising both vertical and horizontal expansions adding approximately 2,000 square feet, followed by comprehensive renovations in 2009-2015 that included electrical upgrades (new 125-100 amp services), plumbing improvements (new water service, heater, furnace), and conversion from a single-family residence to a two-unit dwelling with added kitchen and bathroom facilities. The building's parking situation has been a recurring issue, with multiple reports of driveway blocking incidents between 2023-2024, averaging one case per month, though some calls resulted in citations being issued while others were unable to be verified. A fire alarm system activation was recorded at the property with no actual fire or injuries reported. The property has maintained compliance with various regulatory requirements, including parking variance requests during its conversion to a two-unit residence, and all recorded permits show either completed or properly resolved status.

Risk rating

How 536-538 Duncan 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
72ndpercentile

Out of 1879 buildings in this neighborhood, 526 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
