Rent & eviction protection

Is 1000-1004 Masonic 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.

Built before 1979
Built 1904
2 or more units
6 units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1904
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 6-unit, 4-story multi-family residential building at 1000 Masonic Ave in Haight Ashbury, built in 1904, has undergone significant renovations and faced several challenges in recent years. Most notably, there are multiple active violations from March 2022 regarding repair needs for weatherproofing on siding, stairs, roof deck safety, electrical panel issues, and egress obstructions, all of which remain unresolved as of October 2023. A recent complaint from August 2023 about a protruding window creating a sidewalk hazard is also currently active. The building has experienced recurring fire alarm system issues, with multiple false alarms and malfunction incidents documented between 2009 and 2021, though the fire alarm system was upgraded in 2021 to include low frequency sounders in sleeping areas and comply with current fire codes.

Significant improvements have been made to the property, including the legalization of additional units and comprehensive unit renovations. In 2020-2021, Units 3 and 6 received substantial upgrades, including kitchen and bathroom remodels, window replacements, and electrical improvements. The building completed its soft-story retrofit in compliance with city requirements. Multiple complaints in 2022 regarding heating systems, electrical wiring, and mold issues suggest some ongoing maintenance challenges, though many of these issues were addressed through subsequent permits and repairs. The property has experienced two building fires, with the most recent incident in 2022 resulting in one civilian injury, and various fire safety violations have been recorded and generally addressed through corrective actions. The building's utility systems have seen major updates with the installation of new ADUs (Accessory Dwelling Units) in 2020, and the property has received regular maintenance and upgrades to meet modern safety standards, though some active violations indicate areas requiring further attention.

Risk rating

How 1000-1004 Masonic 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

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
2ndpercentile
