Rent & eviction protection

Is 183 Parnassus 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 1911

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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.

Built 1911
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

183 Parnassus Avenue is a 3-story, 7-unit multi-family residential building constructed in 1911, currently owned by 183 Parnassus Partners LLC. The property has undergone significant improvements in recent years, including major seismic retrofitting as a Tier 3 soft-story building completed in 2016, installation of a new auxiliary dwelling unit, and comprehensive fire safety upgrades. Most notably, in 2024, the building is receiving a fire alarm system upgrade to comply with current fire code requirements, including installation of low-frequency sounders in sleeping areas. The building has undergone multiple infrastructure improvements between 2016-2017, including installation of fire sprinklers, a new electrical service with multiple panels, and comprehensive plumbing updates including removal of the old steam boiler system and installation of new heating units throughout the building.

The property has maintained active compliance with building codes, though it has experienced some maintenance issues over time. A complaint from 2019 regarding a window and heating problem was resolved, and there was a recent underground drainage issue reported in mid-2024. Historic violations from 2000 related to security requirements and lead paint concerns were all abated by 2001, and there was a fire alarm system violation in 2020 that was subsequently corrected. Most construction-related complaints from 2017-2018 regarding surrounding properties and temporary construction impacts were also resolved. Recent activity indicates ongoing maintenance and system upgrades, with current work focused on fire safety improvements and regular building maintenance. The property has been responsive to regulatory requirements, as evidenced by the completion of mandatory soft-story retrofitting and subsequent improvements to meet current building codes.

Risk rating

How 183 Parnassus 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
