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 2014
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Likely exempt from AB 1482. Housing with a certificate of occupancy issued within the previous 15 years is exempt from the state rent cap and just-cause rules.

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 113-unit, 7-story multi-family residential building at 1828-1850 Market Street, constructed in 2014, has experienced several maintenance and regulatory issues in recent years. Most notably, there are persistent concerns regarding the building's heating system, with an active complaint from December 2024 about heat failure in residential units, and multiple boiler permit renewal issues documented between 2022-2024, including violations in 2023 that were eventually abated. Recent maintenance work includes balcony waterproofing in July 2023 (costing $55,925) and boiler replacements in July 2023, though these repairs have been accompanied by tenant complaints about construction notifications and emergency relocation requests.

The building has also faced fire safety and elevator reliability concerns, with the most recent violation recorded in November 2023 regarding sleeping area requirements. Elevator problems were documented in early 2024, and there have been multiple fire alarm and sprinkler system activations, though none resulted in injuries or significant damage. The property underwent various improvements in 2018, including fire safety upgrades and commercial space modifications for Bank of America, and has maintained active compliance with building codes through numerous permits and inspections. The building's management has generally addressed violations and complaints, as evidenced by their resolution through permits and corrective actions, though some issues, particularly related to heating systems, appear to be recurring problems.

Risk rating

How 1828-1850 Market 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

Out of 1027 buildings in this neighborhood, 1027 are predicted to be safer.
