Rent & eviction protection

Is 1727-1729 9Th 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 before 1979
Built 1978

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

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 1727-1729 9th Avenue in San Francisco's Inner Sunset neighborhood, owned by Peter Bee Lim Lee Survivors, is a two-story flats and duplex structure built in 1978. The property has undergone several notable maintenance and compliance activities over its history, including a significant reroofing project in 2018 costing $17,120 and a compliance-related improvement in 1989. A concerning incident occurred in May 2018 when neighborhood residents reported unpermitted tar application and generator use resulting in noxious fumes, though this complaint is now listed as not active. The building has undergone three routine housing inspections of common areas in 2002, 2010, and most recently in 2018, with all coming back as not active.

The surrounding area has experienced various municipal service calls since 2018, including multiple street cleaning requests, graffiti removals, and a parking enforcement issue. The most recent building-related incident was a general complaint about building services in April 2018, which was transferred for further inspection. The property appears to have generally maintained compliance with building codes since the 1989 improvement, with no recorded building violations in recent years. The 311 call records primarily document neighborhood maintenance issues rather than specific building concerns, with the most recent being a general cleaning request in October 2022 that was resolved with no issues found.

Risk rating

How 1727-1729 9Th 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
74thpercentile

Out of 1493 buildings in this neighborhood, 388 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
