By the end, you'll have a clear understanding of how to add value and functionality to your property with an ADU.

What is an ADU?

An Accessory Dwelling Unit (ADU) is an attached or detached residential unit that provides independent living facilities on the same property as a single-family home. These units include provisions for living, sleeping, eating, cooking, and sanitation. ADUs can take various forms, such as efficiency units or manufactured homes.

Benefits of Adding an ADU

Adding an ADU to your property offers numerous advantages:

1. Increased Property Value: ADUs can enhance the overall value of your property.
2. Additional Income: Renting out your ADU can provide a steady income stream.
3. Flexible Living Arrangements: ADUs offer housing solutions for extended family or guests.

Understanding Half Moon Bay’s ADU Regulations

Before you can enjoy the perks of an ADU, it’s important to grasp the local regulations. The City of Half Moon Bay has specific rules regarding ADU planning and permitting, such as zoning requirements, lot size limitations, and setback rules. These guidelines ensure that your ADU integrates seamlessly into the community while meeting all legal standards.

The Planning and Permitting Process

Navigating the planning and permitting process can seem overwhelming, but breaking it down into manageable steps makes it simpler. Here's a step-by-step guide to help you obtain an ADU permit in Half Moon Bay from initial planning and design to final approval.

Step 1: Initial Planning and Design

The first step in creating your ADU is thorough planning and thoughtful design. Consider what type of ADU best suits your needs—whether it be attached, detached, or a garage conversion. Make sure your design complies with the City’s architectural and design standards, such as using similar exterior materials and colors to your primary residence.

Step 2: Assess Zoning Requirements

Your property must meet specific zoning requirements to qualify for an ADU. ADUs are permitted in all residential and certain commercial districts that contain an existing single-family dwelling unit. Additionally, your lot cannot contain another unit or guest house.

Step 3: Understand Setback and Size Regulations

It’s essential to consider setback regulations when planning your ADU. Detached ADUs must have a minimum side setback of 5 feet and a rear setback of 10 feet. Plus, there must be a minimum distance of 6 feet between buildings on your lot. The total gross floor area of your ADU must not exceed 800 square feet, and the combined floor area of all buildings on your lot must comply with the maximum floor area ratio required by your zoning district.

Step 4: Submit a Planning Permit Application

Once you’ve planned your ADU and ensured it meets zoning and setback requirements, the next step is submitting a planning permit application. Your application will be reviewed by various municipal departments, including Public Works and the Coast side Fire Protection District (CFPD).

Step 5: Obtain a Building Permit

With your planning permit approved, you can move forward to obtain a building permit. This step involves a more detailed review of your construction plans to ensure they meet all applicable building codes and safety standards.

Step 6: Plan Review and Approval

Several agencies need to review and approve your plans before you can begin construction. The Coast side County Water District will check if your existing water service can accommodate the ADU, and you'll need to verify with your Sewer Management Agency that the existing sewer lateral has adequate capacity to serve both the primary residence and ADU.

Parking Requirements

Depending on your neighborhood, you may need to provide additional off-street parking for your ADU. For example, neighborhoods like Miramar and Casa del Mar require at least one additional parking space for the ADU.

Declaration of Restrictions

Before you can obtain your building permit, a declaration of restrictions must be filed with the County Recorder. This document ensures that neither the single-family dwelling nor the ADU can be sold separately, and one of the units must be owner-occupied as a principal residence.

Fees and Costs

Be prepared to pay fees for planning and building permits. Additionally, the Coast side Fire and Water District have their own plan review fees that must be accounted for in your budget.

Optimizing Your ADU for Maximum Benefit

Now that you understand the planning and permitting process, let's explore some tips for designing an ADU that meets your needs and complies with local regulations.

Maximize Space with Smart Design

When space is limited, every square foot counts. Utilize built-in storage solutions, multipurpose furniture, and open floor plans to make the most of the available area. Consider lofted beds or fold-out desks to keep the space versatile and functional.

Choose the Right Materials

Select durable, high-quality materials that can withstand the test of time. Opt for energy-efficient windows and appliances to reduce utility costs and enhance the sustainability of your ADU. Additionally, choose materials that complement the aesthetic of your main home to maintain a cohesive look.

Work with Local Contractors
