Rent & eviction protection

Is 475-477 35Th 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 1925

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 1925
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 property at 475-477 35th Avenue is a three-story, two-unit multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1925 and currently owned by Mario & Winnie W De Senna R, this flats and duplex-style building has undergone significant renovations over the past decade. The most substantial improvements occurred between 2015-2016, with major remodeling projects on both the first and third floors. In 2015, work was completed on the first floor to create an exercise room, guest room, study, full bathroom, and laundry area, while the third floor received a new study room, bathroom, and kitchen renovations. The following year, additional renovations were performed on the second floor unit to convert an existing kitchen space into a den, relocate the dining room to create a kitchen/dining area, and add a full bathroom, among other updates. These projects were accompanied by necessary plumbing and electrical work, including kitchen relocations, bathroom additions, and lighting upgrades, all of which have been completed successfully.

The building's maintenance history shows attention to basic infrastructure, including reroofing work completed in 2001 (at a cost of $6,500). The property has also experienced recurring issues with sidewalk parking violations, with five documented incidents between 2019-2023, though these are external neighborhood issues rather than building-specific concerns. The most recent building-related activity was a planning record from 2020 indicating the addition of rooms down (full bathroom and laundry sink) with indirect access and no visual connection, along with confirmation that there were no open Building Code Enforcement cases. While the parking enforcement history shows persistent challenges in the immediate vicinity, these are typical urban street issues and not directly related to the building's condition or management.

Risk rating

How 475-477 35Th 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
53rdpercentile

Out of 1040 buildings in this neighborhood, 489 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
