Rent & eviction protection

Is 818-820 47Th 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.

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 818-820 47th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1964, currently owned by Christopher Gorog. The building underwent significant renovations in October 2014, including comprehensive improvements to both upper floor units featuring kitchen remodels, removal of non-bearing partitions between kitchen and dining areas, window replacements (installing 18 new windows), and electrical upgrades including new lighting and circuitry. A new tankless water heater installation with upgraded gas lines was completed in May 2015. The building has had some compliance issues, with three separate complaints filed regarding unauthorized short-term rental activity between 2015 and 2019, including reports of trash accumulation and indicating the property was being operated as a vacation rental with infrequent owner presence. There were also two building complaints in 2015: one regarding construction noise and illegal parking, and another in 2016 concerning unpermitted rear structure construction, though these cases were marked as not active. A parking enforcement issue was documented in June 2019 for sidewalk parking, which was resolved with a citation. The property's maintenance record shows regular upkeep, with two separate roofing projects completed in 1994 and again in 2014, suggesting ongoing property maintenance by the current owner.

Risk rating

How 818-820 47Th 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
92ndpercentile

Out of 1040 buildings in this neighborhood, 83 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
