Rent & eviction protection

Is 1339-1341 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.

Built 1949

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 two-unit residential building at 1339-1341 27th Avenue in the Central Sunset neighborhood, owned by Nancy E. Lewis, has undergone several significant upgrades and maintenance work since its construction in 1949. Most recently, in 2022, the building received a new furnace installation, following a previous HVAC upgrade in 2018. The property has seen substantial interior improvements, including a comprehensive bathroom and kitchen remodel in 2018 ($50,000), window replacements in 2021, and multiple electrical upgrades corresponding to these renovations. Structural safety has been addressed with a voluntary garage reinforcement project in 2010 that included the installation of additional anchor bolts, clips, and plywood sheathing.

The building's maintenance history shows attention to basic infrastructure, including reroofing work completed in 2011. While there was a period of concern in 2017 with fire complaints regarding hoarding and blocked exits, these were investigated and found to have no merit. More recently, in 2021, there were incidents including a sewage backup and reports of garbage management issues, though these were resolved. The property has generally maintained active upkeep through various permits and improvements, suggesting regular maintenance by the owner. Automated systems like motion-sensor lighting and modern HVAC controls indicate a trend towards energy efficiency improvements. The building's permit history demonstrates a pattern of regular updates to both systems and aesthetics, with particular attention paid to safety features such as egress-compliant windows.

Risk rating

How 1339-1341 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
92ndpercentile

Out of 814 buildings in this neighborhood, 65 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
