Rent & eviction protection

Is 320 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.

Built before 1979
Built 1900

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 1900
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 two-story, four-unit multi-family residential building at 320 Duncan Street in Noe Valley, owned by Suheil and Christine Totah, has undergone several significant modifications since its construction in 1900. Most recently, in 2024, the owners received permits to convert the garage space into storage, remove the garage door, and add a half bath and utility sink, following an active code enforcement case from 2020 regarding unauthorized window modifications. The property has seen regular maintenance and upgrades, including window replacements in 2023 and 2020, a stairway enclosure construction in 2014, and various plumbing improvements including a 40-gallon water heater installation in 2010. Multiple housing inspections in the early 2000s revealed various issues that have since been resolved, including concerns about dry rot in stairs and decks, peeling paint posing potential lead hazards, and various fire safety requirements. The building underwent significant structural scrutiny in 2020 regarding a makeshift unit situation, which was eventually closed in 2022. The property has maintained compliance with major building regulations, with records showing prompt response to violations, including the removal of egress obstructions and repair of unsafe structures. The most recent building permits suggest ongoing improvements to the property's infrastructure while addressing previous code violations.

Risk rating

How 320 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
4thpercentile

Out of 1879 buildings in this neighborhood, 1804 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Director's hearings (past 7 years)
