Rent & eviction protection

Is 3907-3915 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 1921

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.

15+ years since occupancy
Built 1921
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, four-unit residential building at 3907-3915 Balboa Street in San Francisco's Outer Richmond neighborhood, owned by Eric W. Tang, was constructed in 1921 and has generated 184 service requests through the city's 311 system over the past seven years. The most recent service requests from 2025-2026 suggest ongoing concerns with waste management in the area, with three separate reports of overflowing city garbage cans and general debris issues, though one of these was resolved with no additional work needed. Additionally, there are two open service requests related to transit shelter platforms - one from November 2025 and another from January 2026 that was classified as a duplicate. While the building's service request history shows relatively high activity over the past seven years, it's worth noting that there has only been one recorded fire incident during this period, suggesting a reasonable level of fire safety given the building's age and urban location. The property has experienced a notable clustering of service requests in recent months (2025-2026), particularly regarding garbage management, which appears to be an ongoing challenge in the immediate vicinity.

Risk rating

How 3907-3915 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
37th percentile

Out of 1040 buildings in this neighborhood, 655 are predicted to be safer.

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.

Number of units

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

Neighborhood location

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 51.9%
Moderate concern 19.1%
Severe concern 29.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
