Rent & eviction protection

Is 1403 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 1948

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

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 1403 27th Avenue in the Central Sunset neighborhood, owned by Julie Yi Zhou, has undergone several notable improvements since its construction in 1948 as a flat and store property. The most significant recent renovation was completed in 2016, involving comprehensive updates to construct a new bathroom and closet on the second floor, with associated plumbing and electrical work totaling approximately $15,000. Earlier improvements to the property include the installation of a new storefront in 1999 and the replacement of existing windows with aluminum frames in 1992.

The building has experienced recurring issues with street cleanliness in the immediate vicinity, particularly during 2024, with multiple reports of garbage, debris, and abandoned items (including electronics and a mattress) being documented through 311 calls. Between April 2024 and January 2025, there were at least seven separate reports of waste-related issues, all of which were eventually resolved, though not all required active intervention. Additional non-building related incidents include a 2022 graffiti complaint (later closed due to no response from PG&E) and an illegal postings issue from 2021 that remains open as of the last update. While these external factors don't directly reflect on the building's condition, they do indicate ongoing community maintenance challenges in the immediate area, particularly concerning street cleanliness.

Risk rating

How 1403 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
47thpercentile

Out of 814 buildings in this neighborhood, 431 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
