Outer Richmond, SF 94121 1598023 5 units · 2 fl · 1946

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 794 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.

Built before 1979
Built 1946
2 or more units

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 1946
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 5-unit, 2-story multi-family residential building located at 794 47th Avenue in San Francisco's Outer Richmond neighborhood, was built in 1946 and is currently owned by the Roger K & An Trust B. The property has undergone several significant improvements over the years, including a complete copper pipe replacement project in 2008, and two roofing projects - one completed in 2008 costing $7,960 and an earlier one from 1990 that expired. The building experienced multiple fire safety-related violations in 2007, including issues with the fire escape drop ladder maintenance and central alarm system, though all were resolved by March 2007. A routine housing inspection in 2011 was conducted and resolved. More recent maintenance includes street space work in 2009, though this appears to be minor based on the $1 cost.

In terms of recent activity (2023-2024), there have been multiple 311 calls regarding the surrounding public areas, primarily focusing on garbage and debris, with several cases resolved by city services. The most recent infrastructure-related calls in January 2025 were about a fire hydrant and street lighting issues, though these were either resolved or referred to PG&E. A false fire alarm incident was recorded, but notably, there have been no reported civilian injuries or major fire incidents. The building's record shows regular maintenance and prompt attention to violations when they occur, with all historical violations documented as having been abated.

Risk rating

How 794 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
7thpercentile

Out of 1040 buildings in this neighborhood, 967 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
