Rent & eviction protection

Is 3933 Balboa St 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 1947

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 1947
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 3933 Balboa Street, located in San Francisco's Outer Richmond neighborhood, is a two-story structure built in 1947 and currently owned by Philip and Elaine Moy since 2020. The property's documented history shows a recurring pattern of graffiti incidents between 2018 and 2022, with at least seven reports of graffiti on or near the property, including offensive graffiti on sidewalks, other structures, and the building itself. While most of these graffiti cases were resolved through city intervention, the frequency of such events over several years is notable. The most pressing current concern is a sidewalk defect reported in December 2024, involving lifted pavement due to tree roots, which remains open and accepted by the Public Works - Street Use and Mapping department. Other incidents on record include two cases of overflowing city garbage cans (2023 and 2024) and an abandoned vehicle report in 2018, all of which were resolved. A street space permit with a minimal cost of $1.00 was issued in June 2014, though the specific purpose of this permit is unclear from the available data.

Risk rating

How 3933 Balboa St'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
28thpercentile

Out of 1040 buildings in this neighborhood, 749 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
