Moorpark, California
As a professional ADU builder, we provide this updated guide to help you understand Moorpark’s Accessory Dwelling Unit (ADU) regulations. While this guide offers an overview, our expertise ensures your project complies with all local and state requirements.
Jurisdiction
- City Authority: The City of Moorpark regulates ADUs through its zoning code, which aligns with California state mandates.
- Coastal Zone Considerations: Moorpark is not located in the Coastal Zone, so no Coastal Development Permit is required.
- Fire Hazard Areas: Areas within designated fire severity zones may require additional construction standards.
- Zoning Eligibility: ADUs are permitted on lots zoned for single-family or multi-family residential use, subject to local development standards.
Our team confirms your property’s eligibility before we begin the design and permitting process.
State Law Overrides
- State Compliance: Moorpark’s ordinance complies with California’s ADU legislation, enabling faster approvals.
- Ministerial Approval: ADUs that meet all objective criteria are reviewed and approved without public hearings.
- Owner-Occupancy: Not required for ADUs. JADUs must be owner-occupied.
- Multiple Units: Single-family lots may include one ADU and one JADU. Multi-family lots may qualify for multiple conversions and detached ADUs.
We streamline every step of the process by designing within both local and state requirements.
Maximum ADU Size
- Detached ADUs: May be up to 1,200 sq ft, depending on lot size, setbacks, and floor area ratio limits.
- Attached ADUs: May be up to 50% of the main home’s floor area or 1,000 sq ft, whichever is smaller.
- JADUs: Maximum of 500 sq ft, located within the existing home.
- Conversions: Existing legal structures, such as garages or outbuildings, may be converted into ADUs without a strict size cap.
We help you select the right ADU type to meet your needs and fit your property.
Setback Requirements
- Side and Rear Setbacks: New detached ADUs must maintain a 4-foot minimum setback from rear and side property lines.
- Front Setbacks: Must follow the primary zoning district’s minimum front setback requirements.
- Separation: Detached ADUs must be at least 10 feet from the primary home unless fire-rated wall construction is used.
- Conversions: No setbacks are required when converting an existing legal structure.
We’ll design your unit to comply with spacing requirements while maximizing buildable area.
Height Limits
- One-Story ADUs: Maximum of 16 feet in height.
- Two-story ADUs: Depending on the location and compliance with neighborhood design standards, they may be allowed up to 25 feet.
- JADUs: Must stay within the height of the existing home.
Height planning is a key part of our design process. We ensure your ADU meets local code without compromising functionality.
Parking Requirements
- General Rule: Unless exempt, one off-street parking space is required for the ADU.
- Exemptions: No parking is required if:
- The property is within ½ mile of public transit.
- The ADU is created by converting a garage or an existing structure.
- The lot is within a historic district or environmental protection zone.
- Replacement Parking: Not required when converting a garage to an ADU.
We’ll evaluate your property to determine if you qualify for a parking exemption.
Permit Process & Timelines
- Building Permit: Required for all ADU construction and conversion projects.
- Timeline: The city must approve or deny a ministerial application within 60 days.
- Discretionary Review: Not required for ADUs that meet objective development standards.
We prepare and manage your full submittal package to avoid delays and keep your project on schedule.
Impact Fees & Utilities
- Impact Fees: Waived for ADUs under 750 sq ft. Larger units may be subject to traffic, school, or public facility fees.
- Utility Connections: Depending on site conditions and project scope, shared or independent connections may be required.
- School Fees: Typically apply to units over 500 sq ft, based on square footage.
We provide a full project budget up front, including all anticipated fees and connection requirements.
Incentives & Rebates
- State Grant Programs: ADU grants may be available for low- to moderate-income homeowners through California housing agencies.
- Green Incentives: Opportunities may exist for all-electric or energy-efficient designs.
We help you identify cost-saving incentives and assist with any applications as part of your ADU project plan.
