Rent & eviction protection

Is 828-830 Cortland 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 1908

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-unit, two-story building at 828-830 Cortland Avenue in Bernal Heights, constructed in 1908, has experienced significant recent activity and multiple safety concerns. The property has undergone substantial improvements since 2025, including the installation of solar panels and energy storage units, residential remodeling work, and commercial space improvements. However, there have been concerning construction practices documented through multiple complaints in 2025-2026, particularly regarding early morning construction work on weekends, hazardous electrical wiring, and work performed without proper permits. The most recent active complaint from July 2026 details unauthorized weekend construction using heavy machinery and improper waste disposal practices.

The building's recent history shows a pattern of construction and renovation activity, with permitted work totaling over $422,000 in construction costs over the past seven years. While many of the earlier complaints from 2020-2025 have been resolved, the current active complaint suggests ongoing issues with construction practices and community impact. A notable infrastructure improvement in 2026 includes a permit for additional foundation work and concrete slab replacement. A fire incident in January 2022 involving a downed power line was recorded, though fortunately resulted in no civilian injuries or fatalities. Recent complaints in July 2026 regarding a blocked driveway and offensive behavior are still being addressed. The temperature records show no major fluctuations, suggesting stable building conditions outside of the noted incidents.

Risk rating

How 828-830 Cortland 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
5thpercentile

Out of 1276 buildings in this neighborhood, 1212 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
