Rent & eviction protection

Is 977 Clayton 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 1910

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1910
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-unit residential building at 977 Clayton Street, owned by David E Vanderbilt 2013 Rev, is a three-story flats and duplex structure built in 1910 in the Parnassus/Ashbury Heights neighborhood. The property's most significant recent maintenance work was a complete roof replacement in 2017, costing $14,500, which was conducted as an in-kind replacement without changes to the original roof form. Other notable improvements include a 2011 plumbing upgrade that involved replacing a 4-inch clean-out with a new 6-inch clean-out and sidewalk repairs, as well as a deck repair project from 1994 that replaced planking and rails. Two street space and sidewalk permits were issued in 2011 and 2004, and there was a cancelled permit for a one-story detached garage construction in 1990.

The property has experienced recurring issues with abandoned vehicles in the vicinity, particularly during 2017 when multiple reports were made between February and June, though all vehicles in these cases were gone upon inspection. The most recent building-related incident was a general cleaning complaint regarding loose garbage in November 2018, which was resolved. Historical permits from 1981 and 1990, as well as multiple failed vehicle removal attempts from 2016 through 2018, are also on record. The building appears to be regularly maintained, with the most substantial work focusing on essential systems like the roof and plumbing infrastructure.

Risk rating

How 977 Clayton 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
76thpercentile

Out of 526 buildings in this neighborhood, 126 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.
