Rent & eviction protection

Is 501-543 Columbus 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.

15+ years since occupancy
Built 1907
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 32-unit, 3-story multi-family residential building at 501-543 Columbus Avenue in North Beach, owned by 501 Columbus LLC, was constructed in 1907 and has undergone numerous significant renovations and maintenance work over the past few years. Most notably, there have been recent serious maintenance issues, with two significant tenant complaints filed in late 2024 regarding lack of heat and power (December 2024) and ceiling collapse with water leakage (November 2024). The building has completed several major improvements, including ADA compliance updates, plumbing and electrical upgrades, and a substantial re-roofing project in 2022 costing $52,000. A concerning pattern emerged in 2024-2025 with multiple tenant complaints regarding basic services, including heat and water systems. The building is classified as a "Soft Story" structure, having completed its Tier 4 requirements, and has had some fire safety violations that were subsequently corrected.

Recent building improvements (2022-2023) include the installation of ADA bathrooms, electrical systems upgrades, and various plumbing works, though there have been several cancelled or expired permits that indicate some work may have been deferred. The property underwent a significant commercial space transformation in 2021-2022, including the addition of a barber shop, with associated signage and utility upgrades. Historical maintenance records show previous issues with fire safety systems and building access requirements, though these have been generally addressed. The building's recent inspection history shows periodic fire alarm system issues and violations related to sleeping area requirements, which remain open as of November 2023. The property has a history of 311 calls regarding various maintenance and infrastructure issues in the surrounding area, including tree maintenance, sidewalk defects, and street repairs, with several cases still marked as "Open accepted."

Risk rating

How 501-543 Columbus 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

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.
