Rent & eviction protection

Is 1327-1329 27Th Ave 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.

Built 1949
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 1327-1329 27th Avenue in San Francisco's Central Sunset neighborhood is a two-story flats and duplex structure built in 1949 and currently owned by Leong Sui Yee. The property has undergone several infrastructure improvements over the years, with the most recent being a complete reroofing project in August 2023 costing $6,000. This follows a pattern of roof maintenance, as records show previous roofing work in 2005 and 1996, demonstrating ongoing maintenance of this critical building component. The building has seen window upgrades as well, with the installation of vinyl windows in 2008 (replacing earlier aluminum windows from 1985), featuring modern energy-efficient specifications including double-pane construction with a U-factor of 0.30.

Recent activity at the property (2023) has primarily involved external issues not directly related to building maintenance or safety. There were multiple instances of blocked driveways in August 2023, with seven parking enforcement calls leading to several citations being issued, though two cases were deemed invalid due to incomplete reporting information. There was also one report of an abandoned vehicle in June 2023, which was resolved when the vehicle complied with regulations. Other municipal service calls in January 2023 for street cleaning reported no issues were found at the address. The building's maintenance record shows regular upkeep of essential systems, particularly evident in the recent roof replacement and the energy-efficient window upgrades, while the recent service calls primarily relate to parking and street maintenance issues rather than building-specific concerns.

Risk rating

How 1327-1329 27Th Ave'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
84thpercentile

Out of 814 buildings in this neighborhood, 130 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
