Rent & eviction protection

Is 183-185 Duboce 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 1906

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 6-unit multi-family residential building at 183-185 Duboce Avenue, owned by the Ruan/hu Family Trust, was constructed in 1906 and is three stories tall. The property has undergone several significant improvements and faced various challenges over the years. Most notably, it is currently classified as non-compliant with Soft Story requirements as a Tier 3 building, with a failure to submit the required screening form in 2014 and an active complaint regarding non-compliance filed in 2019. In 2017, the building underwent a $63,000 soft story retrofit work. The property experienced a cluster of violations in June 2017 related to safety and maintenance issues, including problems with smoke/alarm systems, fire extinguishers, window hardware, storage, and lead hazards; all were abated by September 2017.

In 2007, the building underwent significant renovations including kitchen remodels in multiple units (#183, #183A, #183B, and #185) and window replacements, which initially generated complaints about potential unpermitted work and asbestos concerns. The building has a history of water-related issues, with complaints about leaks in 2017 and a more serious set of violations in 2004 involving faulty electrical wiring, roof leaks, plumbing problems, and evidence of dry rot and mold. Infrastructure improvements include plumbing upgrades in 2008 comprising new gas lines, sink drainage, water pipes, and installation of six 30-gallon electric water heaters, along with electrical upgrades including new circuits, subpanels, and switchboards. The property has had various maintenance issues documented through 311 calls, including sidewalk defects, graffiti, and waste removal requests. A combustible materials issue was reported and corrected in 2014, and there have been multiple graffiti incidents recorded through 311 calls.

Risk rating

How 183-185 Duboce 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
11thpercentile

Out of 799 buildings in this neighborhood, 711 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
