Rent & eviction protection

Is 830-834 Arguello Blvd 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.

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 three-unit residential building at 830-834 Arguello Boulevard in the Lone Mountain neighborhood, owned by Robert & Shirley Muramoto W, is a three-story flats and duplex structure built in 1906. The property has a documented history of stair-related maintenance issues, with repairs to back wood stairs being addressed in 1987 and again in 2013, the latter costing $9,000 to address dry rot and replace existing staircases while maintaining their original design. A significant cluster of violations was recorded in 2016, primarily focused on lead paint hazards, weatherproofing, and general maintenance, with all violations officially abated by September 2017.

Recent activity at the property has predominantly involved external maintenance issues, particularly regarding parking violations and graffiti. Between late 2023 and 2024, there have been multiple documented instances of illegal parking, including several sidewalk parking violations and driveway blockages, with citations issued in some cases. There have also been recurring graffiti issues on the sidewalk near the property, with the most recent incidents occurring in mid-2024. The building has undergone regular routine inspections by Housing Inspection Services in 2001, 2009, and 2011, which typically resulted in no significant findings. The only recorded fire incident was a motor vehicle accident with injuries, which occurred outside the property and did not involve any occupants of the building.

Risk rating

How 830-834 Arguello Blvd'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
32ndpercentile
