Rent & eviction protection

Is 421-435 Buena Vista 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 1942
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

This 11-unit, single-story multi-family residential building located at 421-435 Buena Vista Avenue in the Buena Vista Park neighborhood was built in 1942 and has undergone several significant improvements and maintenance work over the past few years. Most notably, the building has been actively maintained with recent work including the installation of a mini-split system in 2025 (cost: $9,000), repair of a collapsed facade and awning due to dry rot in 2023 ($4,250), and multiple reroofing projects between 2019-2021 totaling over $60,000. The property has also seen substantial system upgrades, including electrical improvements with the installation of solar PV, EV charger, and 100-amp service upgrade in 2021, along with plumbing upgrades including replacement of galvanized water lines with copper and installation of a tankless water heater in 2019.

The building has a history of addressing various maintenance and compliance issues, including a complete soft-story retrofit for seismic safety, which is now complete. Past violations from 2002 related to fire safety equipment and other building maintenance issues were resolved promptly, and there was a deck replacement compliance issue in 2004 that was also addressed. Recent complaints and service calls have primarily involved external issues such as graffiti removal and park-related concerns, rather than structural or safety problems with the building itself. The property has undergone several cosmetic and functional improvements over the years, including kitchen and bathroom remodels, window replacements, and the conversion of one bedroom into two compliant bedrooms with proper egress, demonstrating ongoing investment in maintaining and upgrading the building's systems and living spaces.

Risk rating

How 421-435 Buena Vista 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.
