Let's dive in!

Understanding ADUs: An Introduction to Accessory Dwelling Units

An Accessory Dwelling Unit (ADU), also known as a granny flat, in-law unit, or secondary unit, is a separate residential unit that is located on the same property as a primary residence. ADUs are becoming increasingly popular in San Diego and other cities as they provide homeowners with a flexible and affordable housing option.

What is an ADU?

An ADU is a self-contained living space that typically includes a bedroom, bathroom, kitchen, and living area. It can be attached to the primary residence, such as a converted garage or basement, or it can be a detached structure, like a backyard cottage or a converted standalone building. ADUs are designed to be fully functional and independent living spaces, providing occupants with privacy and comfort.

Benefits of Building an ADU

There are several benefits to building an ADU in San Diego. These include:

1. Additional Rental Income: Renting out your ADU can provide a valuable source of supplementary income, helping to offset mortgage payments or other expenses.

2. Multigenerational Living: ADUs offer a solution for accommodating aging parents, adult children, or extended family members while maintaining separate living spaces.

3. Increased Property Value: Adding an ADU to your property can significantly increase its market value, providing a solid return on investment.

4. Addressing Housing Shortage: ADUs can help address the shortage of affordable housing by adding more housing options within established neighborhoods.

Types of ADUs

In San Diego, there are different types of ADUs that you can consider:

1. Attached ADUs: These are ADUs that are attached to the primary residence, such as converting a garage or basement into a living space.

2. Detached ADUs: These are standalone structures separate from the primary residence, such as backyard cottages or converted standalone buildings.

3. Junior ADUs: Junior ADUs are smaller units that are created within the existing footprint of the primary residence, typically by converting a portion of an existing bedroom or living area.

ADU Design and Size Considerations

When designing your ADU, there are certain factors to consider to ensure compliance with San Diego regulations. These include:

1. Maximum Size: San Diego has specific regulations regarding the maximum size of an ADU based on the lot size and the type of ADU being constructed.

2. Setbacks: Setbacks refer to the minimum distance required between the ADU and property lines, existing structures, or other features on the property. These setbacks may vary depending on the zoning regulations and the type of ADU being built.

3. Design Harmony: San Diego encourages ADUs to be designed in a way that is compatible with the existing architectural style and character of the neighborhood.

Understanding the basics of ADUs and the benefits they offer is the first step in pursuing your ADU project in San Diego. In the next section, we will explore the specific regulations and requirements set forth by the city for building an ADU.

San Diego ADU Regulations

In this section, we will explore the zoning requirements, size and setback regulations, as well as parking and utility considerations for ADUs in San Diego.

Zoning Requirements

Before proceeding with your ADU project, it is crucial to determine if your property is eligible for ADU construction based on the zoning regulations in San Diego. Zoning regulations dictate where ADUs can be built and what requirements must be met.

Some key considerations include:

1. Residential Zones: ADUs are generally allowed in residential zones, including single-family residential zones and multi-family residential zones.

2. Lot Size Requirements: San Diego may have minimum lot size requirements for ADUs, which can vary depending on the zoning district.

3. Density Limitations: Some areas may have density limitations that restrict the number of ADUs allowed on a property or within a specific area.

Understanding the zoning requirements specific to your property will ensure that you can proceed with your ADU plans without any legal complications.

Size and Setback Regulations

San Diego has specific regulations regarding the size and setbacks of ADUs. These regulations ensure that ADUs are appropriately sized and adequately spaced from other structures and property lines. Key factors to consider include:

1. Maximum ADU Size: San Diego has limitations on the maximum size of ADUs based on factors such as lot size and the type of ADU being constructed (attached or detached).

2. Setback Requirements: Setbacks refer to the minimum distance required between the ADU and property lines, existing structures, or other features on the property. Setback requirements can vary depending on the zoning district and the type of ADU being built.

It is essential to consult the San Diego Zoning Code and work with a professional architect or designer to ensure compliance with size and setback regulations.

Parking and Utility Considerations

Parking and utility requirements are important considerations when planning for an ADU in San Diego. These regulations aim to ensure that there is adequate parking and utility infrastructure to support the additional dwelling unit.

1. Parking Requirements: San Diego generally requires at least one parking space for each ADU. However, there are exceptions to this requirement, such as if the ADU is located within a half-mile of public transit or in a historic district.

2. Utility Connections: ADUs must have proper utility connections for water, sewer, and electricity. It is essential to ensure that the existing utility infrastructure can support the additional load from the ADU.

Understanding the parking and utility requirements specific to your ADU project will help you plan accordingly and avoid any issues during the approval process.

By familiarizing yourself with the zoning, size and setback regulations, as well as parking and utility considerations in San Diego, you will be better equipped to move forward with your ADU plans.

This section will guide you through the process of submitting your plan, navigating the review process, and addressing any required changes or corrections.

Submitting Your Plan to the City

1. Consult with an Architect or Designer: Before submitting your ADU plan, it is advisable to work with a professional architect or designer who has experience in ADU construction and is familiar with the San Diego building codes and regulations. They can help you create a comprehensive and compliant plan.

The review process may involve multiple departments, such as planning, building, and fire departments.

2. Addressing Review Comments: During the review process, you may receive comments or requests for revisions from the city's planning department. It is essential to carefully review these comments and address them promptly. Work closely with your architect or designer to make the necessary changes to your plan and resubmit it for review.

This section will cover important considerations such as choosing a contractor, following building codes and inspections, and completing the final touches of your ADU.

Choosing a Contractor

1. Research and Gather Recommendations: Begin by researching contractors who specialize in ADU construction in San Diego. Ask for recommendations from friends, family, or local real estate professionals who have had positive experiences with contractors.

2. Check Licenses and Credentials: Verify that the contractor you choose is licensed, insured, and bonded. This ensures that they meet the necessary qualifications and can provide quality workmanship.

3. Request and Compare Quotes: Obtain quotes from multiple contractors and compare them based on factors such as cost, timeline, project scope, and references. It is essential to choose a contractor who offers competitive pricing without compromising on quality.

4. Review Past Work and References: Request to see examples of the contractor's previous ADU projects and speak with their references. This will give you insight into their craftsmanship, professionalism, and ability to meet deadlines.

5. Sign a Detailed Contract: Once you have chosen a contractor, ensure that you sign a detailed contract that clearly outlines the scope of work, payment terms, project timeline, and any warranties or guarantees.

Following Building Codes and Inspections

1. Obtain Necessary Permits: Before starting construction, ensure that you have obtained all the necessary permits from the city of San Diego. This includes building permits, electrical permits, plumbing permits, and any other permits relevant to your ADU project.

2. Adhere to Building Codes: Throughout the construction process, it is crucial to follow all relevant building codes and regulations. This includes structural requirements, electrical and plumbing standards, fire safety measures, and accessibility guidelines.

3. Schedule Inspections: Coordinate with the city's building department to schedule inspections at various stages of the construction process. Inspections may include foundation inspections, framing inspections, electrical inspections, plumbing inspections, and final inspections.

4. Address Inspection Feedback: If any issues or deficiencies are identified during inspections, work closely with your contractor to address them promptly. This may involve making necessary corrections or modifications to bring your ADU into compliance with building codes.

Completing Final Touches

1. Interior Finishes: Once the structural and utility components of your ADU are complete, focus on the interior finishes. This includes flooring, cabinetry, countertops, paint, fixtures, and any other design elements that will make your ADU functional and aesthetically pleasing.

2. Landscaping and Exterior Enhancements: Pay attention to the exterior of your ADU by landscaping the surrounding area and adding any desired enhancements such as a patio, deck, or fencing. Ensure that your landscaping adheres to any applicable regulations or guidelines.

3. Final Inspections and Certificate of Occupancy: Once all construction and finishing touches are complete, schedule a final inspection with the city's building department. Upon passing the inspection, you will receive a Certificate of Occupancy, indicating that your ADU is safe and ready for habitation.

By carefully selecting a contractor, following building codes and inspections, and completing the final touches, you can ensure a successful construction and completion phase for your ADU project in San Diego. In the next section, we will explore important post-construction considerations.

Post-Construction Considerations

Congratulations on completing the construction of your ADU in San Diego! However, there are still some important considerations to keep in mind now that your ADU is ready for occupancy. This section will cover rental rules and regulations, property tax implications, and maintaining your ADU.

Rental Rules and Regulations

1. Familiarize Yourself with Local Laws: It is crucial to familiarize yourself with the rental laws and regulations in San Diego. This includes understanding tenant rights, lease agreements, rent control ordinances, and eviction procedures. Consult with a local attorney or property management professional for guidance.

2. Determine the Rental Terms: Decide on the rental terms for your ADU, such as the monthly rent, lease duration, and any additional fees or requirements. Ensure that your rental terms comply with local laws and are fair and reasonable.

3. Screen Potential Tenants: Implement a thorough tenant screening process to ensure that you select reliable and responsible tenants. This may include conducting background checks, verifying income and employment, and checking references.

4. Maintain Proper Documentation: Keep accurate records of all rental-related documents, such as lease agreements, rental payments, and maintenance requests. This will help you stay organized and protect your rights as a landlord.

Property Tax Implications

1. Assess Property Tax Changes: Adding an ADU to your property may impact your property tax assessment. Contact the San Diego County Assessor's Office to determine how the ADU will affect your property taxes. They can provide guidance on any potential tax increases or exemptions that may apply.

2. Understand Potential Exemptions: In California, certain ADUs may be eligible for property tax exemptions under specific circumstances. For example, ADUs built for affordable housing purposes may qualify for exemptions. Research and consult with the appropriate authorities to determine if any exemptions apply to your ADU.

Maintaining Your ADU

1. Regular Maintenance: Just like any other property, your ADU will require regular maintenance to ensure its longevity and functionality. Create a maintenance schedule for routine tasks such as cleaning, landscaping, HVAC system servicing, and appliance inspections.

2. Respond to Maintenance Requests: Promptly address any maintenance requests or issues reported by your tenants. This will help maintain a positive relationship with your tenants and ensure the proper functioning of your ADU.

3. Stay Up-to-Date with Regulations: Stay informed about any changes or updates to local regulations and building codes that may affect your ADU. This includes keeping track of any required inspections or renewals of permits.

4. Consider Property Management: If managing your ADU becomes overwhelming or you prefer a more hands-off approach, consider hiring a professional property management company. They can handle tenant screening, rent collection, maintenance, and other property management tasks on your behalf.

By understanding and following rental rules and regulations, being aware of property tax implications, and maintaining your ADU properly, you can ensure a successful post-construction phase for your ADU project in San Diego.
