Rent & eviction protection

Is 55-57 Ramona 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 1912

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

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 1912
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 two-unit residential building at 55-57 Ramona Avenue in Mission Dolores, owned by David Leong, is a two-story flats and duplex structure built in 1912. The property has undergone several significant renovations, most notably a substantial $60,000 remodeling project in 2015 that added and renovated bathrooms and kitchens throughout the building, including extensive electrical work involving 16 circuits, 20 lights, and multiple appliances. In recent years, the building has faced some maintenance challenges, including a sewage leak repair in May 2023, which coincided with a violation notice regarding deteriorated exterior drainage pipes that was filed on May 2, 2023, and resolved by July 28, 2023. The building's maintenance history shows attention to necessary updates, with previous work including window replacements, stair and deck renovations in 2010, and a new roof installation in 2002.

Recent activity at the property has been predominantly focused on addressing parking concerns, with multiple 311 calls made between September 2024 and January 2025 regarding driveway blocking situations, resulting in at least three citations being issued. The building's infrastructure improvements over the years suggest regular maintenance and upgrading of essential systems, though the 2023 plumbing issues and drainage concerns indicate there may be ongoing challenges with the building's plumbing systems. The property has maintained compliance with building codes following the recent violation, and historical permit records show consistent attention to both cosmetic and structural improvements, including a notable electrical system upgrade in 2003.

Risk rating

How 55-57 Ramona 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
