Outer Richmond, SF 94121 1510001 3 units · 2 fl · 1909

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.

Rent & eviction protection

Is 503 34Th 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 1909

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 two-story multi-family residential building at 503 34th Avenue, owned by Yim N Louie Der Revoc Fmly, was constructed in 1909 and contains three units, with retail space in a flat configuration. The property has undergone several significant improvements over the years, most notably a complete window replacement project in 2015 costing $8,000, involving 16 Andersen 100 Fibrex single-hung windows on the front and side facades. The building recently received electrical system upgrades in June 2023, with a sub-panel replacement bringing the system up to current code standards. Historical records show various exterior improvements, including siding installations in 1999 and structural repairs to the restaurant front in 2001.

The property has experienced some maintenance challenges in recent months, with an electrical incident reported in June 2024 involving sewage back-up discharge from a side sewer vent, though this was resolved by field personnel. There has been a notable pattern of noise complaints throughout 2024, with multiple reports filed between March and July, some of which remain open as of July 2024. While the building has had minimal fire-related incidents, with only one medical assistance call recorded, the recent noise issues may indicate some ongoing concerns regarding resident comfort. The property's historical permit records suggest regular maintenance and improvements, with most recent work focusing on electrical infrastructure and window upgrades.

Risk rating

How 503 34Th 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
17thpercentile

Out of 1040 buildings in this neighborhood, 863 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
