Rent & eviction protection

Is 1000-1018 Cortland 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 1917
2 or more units
10 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.

Built 1917
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 10-unit apartment building at 1000-1018 Cortland Avenue in Bernal Heights, owned by David Parker Properties LLC, was constructed in 1917 and has undergone significant renovations and improvements over the years. Most notably, the building completed a comprehensive fire safety upgrade in 2023-2024, including the installation of heat detectors in un-sprinklered areas and low-frequency horns in sleeping areas to comply with San Francisco Fire Department requirements, with permits showing a total investment of approximately $33,140. The property underwent a seismic soft-story retrofit in 2016-2017, demonstrating compliance with current safety standards, and has maintained its systems with a 400-amp electrical service upgrade and new water main installation in 2019.

Recent active building violations from September 2024 raise concerns about current resident conditions, citing issues with floor coverings, windows, and missing smoke/carbon monoxide detectors. The building has experienced repeated fire safety-related inspections and corrections between 2009 and 2024, though most recent complaints have been resolved or found to have no merit. Past renovation work has included bathroom modernizations in Units 1 and 3 (2020), commercial kitchen installations, and various plumbing upgrades. The property has a history of maintenance and compliance issues dating back to 2001, including sewer problems, unauthorized plumbing work, and historical violations related to gas safety and fire safety equipment, though most have been resolved. While the building has made substantial investments in safety systems and infrastructure, the presence of recent active violations suggests some ongoing maintenance challenges.

Risk rating

How 1000-1018 Cortland 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
4thpercentile

Out of 1276 buildings in this neighborhood, 1225 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
