Coronado ADU FAQs

Obtaining an ADU construction permit in Coronado involves several steps to ensure your project meets local regulations and standards. The process typically begins with a site assessment, where ADU builders evaluate your property to identify specific requirements. From there, custom ADU design plans are developed to suit your needs while adhering to city zoning laws. These plans are then submitted to the local planning department for approval.

Once your plans are approved, the construction phase begins. Experienced ADU builders will handle every aspect of the process to ensure a high-quality build. This includes securing necessary permits, preparing the site, and overseeing the construction from the foundation to the finishing touches. Whether you’re building a tiny home, granny flat, or in-law suite, our team ensures a seamless and stress-free experience.

The result is a beautifully crafted, functional ADU that enhances your property’s value and creates opportunities for additional rental income.

Yes, you can finance the construction of an ADU in Coronado. There are several financing options available to homeowners looking to build an Accessory Dwelling Unit. These options can help make your ADU project more affordable and manageable.

ADU Financing Options in Coronado:

1. Home Equity Loans: Use the equity in your existing home to finance your ADU project. This option typically offers lower interest rates and favorable terms.

2. Home Equity Line of Credit (HELOC): Similar to a home equity loan, a HELOC allows you to borrow against your home’s equity but provides a revolving line of credit, offering flexibility in how you use the funds.

3. Cash-Out Refinance: Refinance your existing mortgage for a higher amount than you currently owe, and use the extra cash to fund your ADU construction.

4. Construction Loans: These short-term loans cover the cost of building an ADU and convert into a mortgage once construction is complete.

5. Government Programs and Grants: Look for local and state programs that offer financial incentives or grants for building ADUs. In California, there are specific programs aimed at increasing the availability of ADUs.

6. Personal Loans: Unsecured personal loans can be used for ADU construction, though they may come with higher interest rates compared to secured loans.

By exploring these financing options, you can find a solution that fits your financial situation and helps you achieve your goal of building an ADU in Coronado. Partner with Nestadu to navigate the financing process and bring your ADU project to life.

What are the ADU Zoning Requirements for Coronado?

In Coronado, ADU zoning requirements are designed to allow more homeowners to build accessory dwelling units. All properties zoned for single-family, two-family, or multifamily use may be eligible to build ADUs, making it easier to enhance your property with additional living space.

Eligibility Criteria for ADUs in Coronado:

1. Single-Family Zoning:

•Properties zoned for single-family use are eligible to add one ADU. This allows homeowners to create additional living space without changing the primary use of their property.

2. Two-Family Zoning:

•Properties zoned for two-family use can also include an ADU. This zoning category is ideal for duplex properties looking to expand their living arrangements or rental opportunities.

3. Multifamily Zoning:

•Multifamily properties zoned for multiple units can incorporate ADUs as well. This provides an excellent opportunity for apartment buildings and other multifamily residences to add more units and maximize their rental income potential.

By meeting these zoning requirements, homeowners in Coronado can take advantage of the benefits ADUs offer, such as increased property value, rental income, and flexible living arrangements. 

What Are the ADU Size Requirements in Coronado?

In Coronado, the size requirements for ADUs vary depending on the type and configuration of the unit. Knowing these requirements is essential to ensure your project complies with local regulations.

ADU Size Requirements in Coronado:

  1. Junior ADUs (JADUs):

    • Maximum size: 500 sq. ft.
    • JADUs are smaller units, typically created by converting a portion of an existing single-family home.
  2. One-Bedroom Detached ADUs:

    • Maximum size: 850 sq. ft.
    • These fully detached units offer a compact living space with one bedroom.
  3. Two-Bedroom Detached ADUs:

    • Maximum size: 1,000 sq. ft.
    • Larger detached units designed for additional living space and privacy with two bedrooms.
  4. Attached ADUs:

    • Maximum size: Up to 1,000 sq. ft. or 50% of the size of the existing primary residence, whichever is greater.
    • Attached ADUs are connected to the main home and provide a substantial amount of extra living space.

By following these size guidelines, homeowners in Coronado can ensure their ADU projects meet zoning and building code requirements while maximizing the potential of their property.

In Coronado, the maximum height for detached ADUs is 16 feet. This height restriction ensures that ADUs blend well with the existing neighborhood aesthetics and do not overpower the primary residence.

By adhering to this height requirement, homeowners in Coronado can ensure their ADU projects comply with local zoning regulations.

The number of ADUs you can build in Coronado depends on your property’s zoning. Knowing these zoning rules is key to ensuring your project complies with local regulations.

ADU Limits Based on Zoning in Coronado:

  • Single-Family Zones
    • Homeowners can build one ADU and one Junior ADU (JADU) per property.

  • Two-Family or Multi-Family Zones
    • You’re allowed to add either two detached ADUs or convert up to 25% of existing non-living spaces—such as storage rooms or garages—into ADUs.

By following these zoning rules, homeowners in Coronado can unlock their property’s full potential by adding functional and valuable living spaces.

From January 1, 2020, to January 1, 2025, homeowners in Coronado are not required to live on-site to obtain an ADU permit. This temporary regulation gives property owners greater flexibility to add ADUs to their properties without the need for owner occupancy.

Yes, you can rent out your ADU in Coronado for long-term rentals. However, the city does not allow ADUs to be rented out for short-term stays, such as Airbnb rentals under 30 days. This regulation helps maintain community stability and ensures ADUs are used for more permanent housing solutions.

In Coronado, ADUs are required to follow minimum setback guidelines. These setbacks must be at least 4 feet from the side and rear property lines. This spacing helps ensure proper distance from property boundaries, maintains privacy, and keeps the ADU in compliance with local zoning regulations.

No, dedicated parking is not required for ADUs in Coronado. This regulation makes it easier to add an ADU to your property by removing the need for additional parking spaces, allowing you to better utilize your available space.

When planning to build an ADU in Coronado, there are several key factors to consider beyond the basic regulations to ensure a smooth and successful project:

1. Easements

• Check for any easements on your property that could affect where you can build your ADU. Easements may limit construction in certain areas, so it’s important to identify them early in the planning process.

2. HOA Regulations

• If your property falls under a Homeowners Association (HOA), review their rules and guidelines. HOAs may have specific requirements regarding the size, design, or placement of your ADU.

3. Utility Connections

• Plan how your ADU will connect to existing utilities like water, sewer, electricity, and gas. Make sure your plans comply with local codes and include proper utility hookups.

4. Lot Coverage and Floor Area Ratio (FAR)

• Understand Coronado’s lot coverage and floor area ratio (FAR) requirements. These rules determine how much of your property can be covered by structures and the maximum allowable floor area.

5. Design and Aesthetics

• Ensure your ADU design complements your primary home and adheres to any architectural guidelines set by Coronado or your HOA. A well-designed ADU can enhance your property’s overall look and value.

6. Permitting Process

• Familiarize yourself with Coronado’s permitting process. This includes submitting plans, obtaining approvals, and scheduling inspections. Understanding the timeline and requirements can help you avoid unnecessary delays.

7. Environmental Impact

• Consider the environmental impact of your ADU. Using sustainable building materials and energy-efficient systems can reduce your ecological footprint and save on long-term costs.

8. Fire Safety and Access

• Make sure your ADU meets fire safety standards, including smoke detectors, fire extinguishers, and proper access for emergency services.

By addressing these important factors, you can set your ADU project up for success. At Nestadu, we’re here to guide you through every step of the process—from planning and design to construction and final inspections. Contact us for expert support and to bring your ADU vision to life.

Under the California Housing Opportunity and More Efficiency (HOME) Act, also known as SB9, property owners in Coronado can split their single-family residential lots and build up to two residential units on each new lot. This allows for the potential creation of up to four units on a single-family parcel, offering more opportunities for additional housing.

Key Benefits of SB9:

  1. Increased Housing Options
    • You can add more units to your property, increasing rental income potential and providing greater flexibility for housing needs.

  2. Streamlined Approval Process
    • The process for lot splits and additional units is ministerial, meaning it does not require discretionary reviews or public hearings as long as all criteria are met.

  3. Owner Occupancy Requirement
    • If you decide to split your lot, you are required to live in one of the units for at least three years, which helps maintain community stability.

Additional Details:

  • Recent Developments
    • Legal challenges have affected the implementation of SB9 in some charter cities, but the law remains active across most areas in California.

  • Local Regulations
