Rent & eviction protection

Is 4534-4540 Mission 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.

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.

Built 1927
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 21-unit, 3-story multi-family residential building at 4534-4540 Mission Street, constructed in 1927, has undergone numerous significant improvements and faced various challenges in recent years. Most notably, the building achieved compliance with soft-story retrofit requirements (Tier 4) and has consistently addressed fire safety concerns, with the latest fire alarm system upgrade completed in October 2024 at a cost of $40,009. Multiple renovation projects have been undertaken, including a bathroom remodel in 2023 and the controversial addition of four accessory dwelling units in 2018. The building has experienced recurring elevator issues, particularly in 2019, along with several complaints regarding interior conditions (floors, windows, mold) between 2018-2023.

The property has a history of addressing various code violations, with the most recent fire safety violation issued in November 2023 regarding sleeping area requirements.

Recent municipal service calls between 2023-2024 have primarily related to exterior maintenance, including graffiti removal and sidewalk cleaning.

Risk rating

How 4534-4540 Mission 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

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
0thpercentile

Out of 149 buildings in this neighborhood, 149 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
