Rent & eviction protection

Is 277 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.

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 277 Duncan Street is a two-unit, two-story multi-family residential building located in San Francisco's Noe Valley neighborhood, constructed in 1900. The building has undergone several significant improvements, including a vertical and horizontal addition completed in 1989 and a notable interior renovation in 1990 that involved swapping the locations of the bathroom and kitchen. A serious set of maintenance issues came to light in 2016 when residents reported problems including humidity-related mold affecting carpets and belongings, damaged kitchen and bathroom fixtures, termite damage, dry rot on decks, and problems with recently installed siding. These violations, primarily related to interior surfaces and building structures including stairs, decks, and railings, were officially documented and went through a Notice of Violation process, with final resolution occurring in March 2017.

The building's more recent history, from 2018 to present, shows relatively routine urban maintenance issues with no significant building violations or complaints on record. There have been several 311 calls related to street cleaning and abandoned vehicles between 2011 and 2024, including a recent report of abandoned furniture in July 2024, but these external matters did not directly involve the building's condition or management. While the property had some notable building concerns in 2016-2017, there are no documented building violations or major complaints in the more recent years, suggesting the previous maintenance issues were addressed, though it should be noted that the most recent documented building condition history is from March 2017.

Risk rating

How 277 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
81stpercentile

Out of 1879 buildings in this neighborhood, 357 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
