Rent & eviction protection

Is 664-666 29Th 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 1910

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 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 664-666 29th St in Noe Valley, constructed in 1910, has undergone several significant renovations and faced some notable maintenance challenges over its history. The property has experienced three documented fire safety issues since 2017, including a blocked exit (2017), sprinkler/standpipe system concerns (2021), and most recently, alarm system problems (2023-2024) which were resolved in January 2024. The building has undergone several major improvements, including a kitchen remodel in 2008 that featured new cabinetry, appliances, and lighting, and more substantial work in the late 1980s involving fire roof repairs, foundation repair, and the addition of a bathroom and closet in the attic. Earlier repairs addressed dry rot issues and included a significant reroofing project in 2011 costing $16,525.

Recent activity around the property has primarily involved parking enforcement and street maintenance issues, with multiple reports of abandoned vehicles and driveway blockages in 2023-2024. There was a water leak incident reported in February 2024 that was resolved by staff. The building’s fire alarm system issues in late 2023-2024 and the blocked exit incident in 2017 suggest that maintaining clear egress routes and ensuring fire safety systems are functioning properly has been an ongoing concern. The property also experienced some structural challenges in its early years, as evidenced by the foundation repair work required in 1989 and the dry rot remediation in 1998.

Risk rating

How 664-666 29Th 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
61stpercentile

Out of 1879 buildings in this neighborhood, 733 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
