Rent & eviction protection

Is 4827-4829 19Th 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 1908
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 property at 4827-4829 19th Street is a 5-unit multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood. Built in 1908 and currently owned by the John D Moriarty 2012 Revocable Trust, this building has experienced several maintenance and safety issues over recent years. Most notably, there are current concerns about water intrusion and potential mold growth, with complaints filed in 2023 and 2024 regarding roof leaks and water damage. The building has a documented history of lead paint concerns, with violations issued in 2018 regarding peeling paint and lead hazard warnings, though these were formally abated by July 2018.

Earlier building inspections revealed various maintenance issues that were addressed over time, including problems with windows (dry rot, non-functioning), plumbing systems, and security features. A significant cluster of violations was documented in 2002, including issues with mold/mildew, smoke detector requirements, window repairs, hot water storage capacity, sink repairs, egress obstructions, security locks, and paint conditions. While many of these older violations were eventually resolved, the recurrence of water-related issues and recent complaints about mold suggest ongoing maintenance challenges. The building also underwent some external repairs in 2009, with work performed on damaged siding. Recent 311 calls have documented various issues including garbage and debris concerns, and there have been accepted complaints regarding both mold/mildew and pest issues in 2024, indicating continued concerns about building maintenance and environmental conditions.

Risk rating

How 4827-4829 19Th 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
