Rent & eviction protection

Is 20-26 Dorland 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.

Built 1913

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 1913
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 two-story multi-family residential building at 20-26 Dorland Street in Mission Dolores, owned by Kerwin P. Yuen and Pauline Lee, has undergone several significant renovations and faced multiple maintenance challenges since its construction in 1913. Most recently, in September 2024, permits were filed to replace floor joists and cantilever beams between units 20 and 22, suggesting ongoing structural maintenance (status: filed). In 2023, major upgrades were completed including kitchen and bathroom renovations (tile upgrades, countertop replacement, pipe replacement) with a cost of $28,600, representing one of the more substantial recent improvements to the property (completed). However, the building has experienced several concerning maintenance issues over the past decades, including a troubling pattern of plumbing and water-related problems. A 2019 complaint noted water damage under the kitchen sink, while multiple complaints in 2016 reported no hot water issues.

The building's maintenance history shows attention to basic upkeep, with records of roof replacements in 1989 and 2007 (both completed), and repairs to address dry rot on the deck in 2011 (completed). A cluster of violations from 2001 and 2016 indicates periods of required improvements, including fire safety enhancements and security upgrades, though all these violations were subsequently abated. The property has faced several tenant complaints regarding habitability issues, particularly in 2016, when residents reported problems with water heating, flooring (possible asbestos concerns), and paint condition (possible lead concerns). More recent tenant concerns in 2020 involved unpermitted construction activity and associated noise disturbances. While many of these historical violations and complaints have been resolved, the building's recent structural maintenance work (pending as of September 2024) suggests ongoing attention to building integrity.

Risk rating

How 20-26 Dorland 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
24thpercentile

Out of 799 buildings in this neighborhood, 607 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
