Lancaster ADU Regulations & Building Guide

Lancaster is located in Southern California and offers a blend of urban and suburban experiences, attracting residents and visitors alike.

California State ADU Laws

California has some of the most progressive ADU legislation in the country. Recent laws including AB 68, SB 13, and AB 881 have significantly streamlined the ADU approval process and reduced barriers for homeowners.

Key California ADU Regulations:

• Size Limits: Detached ADUs can be up to 1,200 sq ft. Attached ADUs can be up to 50% of the primary dwelling or 1,200 sq ft, whichever is less.
• Setbacks: Minimum 4-foot side and rear setbacks for detached ADUs.
• Height: Generally up to 16 feet, with some exceptions for two-story ADUs (up to 25 feet in certain zones).
• Parking: No additional parking required in most cases, especially near transit.
• Owner Occupancy: No owner-occupancy requirement until 2025 for most ADUs.

Lancaster Local Requirements

While California state law provides baseline regulations, Lancaster may have additional local requirements. GatherADU's team stays current with Lancaster's specific zoning codes, architectural guidelines, and permit processes to ensure your ADU project meets all requirements.

Common local considerations in Lancaster include:

• Design review requirements and architectural standards
• Utility connection fees and impact fees
• Fire department access requirements
• Neighborhood-specific overlay zones

California law (AB 68, AB 881, SB 9, and subsequent legislation) guarantees your right to build ADUs. Cities cannot:

• Require owner-occupancy for ADUs permitted after 2020
• Require additional parking for ADUs near transit
• Charge impact fees for ADUs under 750 sq ft
• Deny ADUs that meet state minimum standards
• Impose lot coverage limits that prevent a 800 sq ft ADU

If you believe your ADU application is being unfairly denied, California HCD can intervene on your behalf.
