Rent & eviction protection

Is 53-55 Lupine 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.

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 1951
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 53-55 Lupine Avenue, owned by Paul & Eunyoung Lee, is a two-story flat/duplex constructed in 1951. The property has undergone significant modifications and improvements over recent years, most notably the successful addition of an ADU (Accessory Dwelling Unit) in 2020, conversion work valued at $26,876. In 2023-2024, crucial safety improvements were implemented, including the installation of a fire sprinkler system with 13 sprinklers in the ground floor dwelling ($14,799) and a new sprinkler monitoring system ($8,656). More recent work includes a scheduled flat roof overlay with specified materials, costing $12,000, showing ongoing maintenance commitment.

The building has experienced several compliance and safety-related issues over its history, including complaints in 2022 regarding unpermitted construction and boiler work, though these complaints are now marked as not active. A cluster of complaints in 2019-2020 concerned construction noise and possible unpermitted work, primarily during the renovation and modernization phase that included kitchen and bathroom remodels in both units. The property's systems have been extensively upgraded, with new furnace heating units installed in 2022 to address specific complaints, along with comprehensive plumbing and electrical work throughout the building. The building's fire safety systems have been notably improved, with multiple alarm system activations recorded, all of which were either malfunction-related or unintentional with no fire incidents or civilian injuries reported. Recent municipal service calls in late 2023-2024 have primarily concerned street cleaning and maintenance issues in the vicinity of the property, rather than building-specific concerns.

Risk rating

How 53-55 Lupine 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
90thpercentile

Out of 272 buildings in this neighborhood, 27 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
