Rent & eviction protection

Is 340-342 Valley 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 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.

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 property at 340-342 Valley Street is a two-unit, two-story multi-family residential building located in Noe Valley, owned by David R. Dupont and constructed in 1900. The building's maintenance history shows several significant improvements, including a horizontal addition completed in 1989, kitchen renovations in the same year, and bathroom floor and sub-framing repairs completed in 1985. A reroofing project initiated in 1996 is now listed as expired.

Recent activity around the property has primarily involved parking enforcement matters, with multiple reports of abandoned vehicles between 2022 and 2024, though most were resolved without incident or involved vehicles complying with parking regulations. There have been some property-related issues needing attention, including an open case from October 2020 regarding tree roots lifting the sidewalk, and a completed case in August 2021 concerning improperly affixed illegal postings that required removal by the SES Graffiti Crew. A temporary moving sign request from January 2022 is currently listed as open. The building's permit and violation history suggests regular maintenance and improvements were performed during the 1980s, though fewer documented improvements are visible in recent decades.

Risk rating

How 340-342 Valley 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
87thpercentile

Out of 1879 buildings in this neighborhood, 244 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.
