Considering building an accessory dwelling unit (ADU)? A crucial decision early on is whether to hire an ADU architect or opt for a design build contractor. An ADU architect specializes in designing ADUs, ensuring compliance with local zoning laws and maximizing functionality. Understanding the advantages and potential drawbacks of working with an ADU architect, such as design customization and cost considerations, is essential to making an informed decision. This guide will help you weigh the pros and cons of ADU architects versus design build contractors, so you can choose the best option for your project.
Understanding the Role of an ADU Architect
An ADU architect specializes in designing accessory dwelling units with a focus on maximizing space, functionality, and meeting regulatory requirements. These professionals are trained to create designs that comply with local zoning laws, building codes, and specific ADU regulations in areas like San Diego. While hiring an ADU architect near me is not always mandatory, their expertise can significantly improve the design, flow, and livability of your ADU, especially for more complex projects.
Architects may also handle the permitting & revision process with the city, typically charging for any revisions on an hourly basis. Architects usually make referrals to contractors who could complete the build for you. This may be the first time build cost is discussed in detail, as it is often difficult to find a contractor willing to fully price out plans until they are approved because it’s a time consuming exercise.
Is an ADU Architect Required to Design an Accessory Dwelling Unit?
No, you are not required to have a licensed ADU architect design your plans. In California, a licensed architect is only required to “stamp” the plans if you are constructing a residential structure taller than two stories. However, a licensed engineer must stamp the structural portion of the plans.
When should I hire an architect for my ADU?
The decision to hire an ADU architect depends on the complexity and customization of your project. There are a few instances in which we recommend working with an ADU architect for your project.
- Highly custom ADU plans (think unique architectural features, non-standard windows, intricate details). Read about the custom plan options that SnapADU provides.
- Attached ADU plans (when you want the granny flat as an addition to your current home, so the existing conditions will be a major factor in consideration). Read about attached ADU vs detached ADU.
- Garage conversions (these are smaller projects, so the plans can be bid out to “handyman” type contractors who may be more cost competitive for that project size). Read about when it makes sense to convert a garage vs. demo and start from scratch.
The Benefits of Working with an ADU Architect
There are also several key advantages to working with an architect on your ADU, particularly for more complex projects:
- Custom Design Expertise: ADU architects specialize in creating tailored designs that maximize both functionality and aesthetics. They can help craft a unique space that integrates seamlessly with your main home, ensuring it matches your style and needs.
- Attention to Detail: Architects often have a deeper focus on design elements like window placement, natural light, storage solutions, and overall flow, leading to a more livable and thoughtfully designed ADU.
- Compliance with Local Regulations: Experienced ADU architects are well-versed in local & state ADU laws, building codes, and permitting requirements. Their knowledge helps ensure that your project complies with regulations from the start, reducing the risk of issues during the approval process.
- Ideal for Complex or Multi-Story ADUs: For larger or multi-story ADUs, an architect’s expertise is particularly valuable. They can help navigate structural challenges and ensure the design accommodates complex requirements, such as height limits and multi-level layouts.
By working with an experienced ADU architect, homeowners can benefit from personalized designs, enhanced livability, and assurance that the project will meet local regulations, making it an excellent choice for those seeking more customized ADU solutions.
ADU Architecture Costs: What to Expect
ADU architect costs in San Diego can vary greatly depending on the scope of the project. The market rate for an architectural firm to design your ADU plans and complete your construction drawings is $10,000 – $18,000 and up, depending on how intricate your designs are. This usually includes the design process, basic site evaluation, architectural plans, and revisions. However, this fee may increase for projects located in areas with more stringent regulations, such as coastal zones or properties governed by HOAs. If you’re searching for a San Diego ADU architect, it’s essential to ask for a detailed estimate up front, as prices can vary significantly based on the firm’s experience and the complexity of your project.
What about hiring an “architect friend” to design & permit my ADU?
It can be tempting to try and save a few thousand dollars on plans, either by using pre-approved plans or perhaps by having a family friend handle the plans. However, when plans are not evaluated by a contractor, build costs can quickly escalate. As a result, the few thousand dollars you may save on plans could quickly evaporate in higher build costs. Also, unless someone has experience with the nuances of ADU regulations & the permitting process, uncertainties can lead to costly and time consuming revisions.
Smaller Architects and Their Limitations
Working with a smaller operation or a “one-man-show” ADU architect can be an attractive option for homeowners looking to save money upfront. These solo architects or drafters may charge lower fees, which can seem appealing, but there are important considerations:
- Limited Experience with ADUs: While they may have general architectural experience, solo architects often lack the specialized knowledge of ADU regulations, which can lead to design inefficiencies or challenges with permitting. Given the unique zoning laws and building requirements that govern ADUs, this can lead to costly revisions and delays down the road.
- Capacity and Time Constraints: Solo architects may be juggling multiple projects, meaning they may not have the resources to dedicate full attention to your ADU. This can slow down the design process and delay project completion.
- Minimal Project Oversight: A solo architect may not offer comprehensive project oversight, which means you could be left managing coordination between designers, engineers, and contractors yourself.
Do you need architectural plans to build an ADU?
Yes, you will need a full set of construction drawings, including a site plan, architectural plans, structural plans, and energy calculations (T-24), to obtain permits and build your ADU. These drawings require a significant amount of time for a designer or architect to complete, even if you are starting with “off the shelf” plans. You can choose to work with an ADU architecture firm or a design-build company, both of which can handle the drafting and design process.

Alternatives to Hiring an ADU Architect
Considering Different Type of ADU Companies
When thinking about an ADU project, it’s important to consider various types of companies, such as ADU consultants, architects, and ADU design build firms. Each offers a different approach to handling ADU projects. While ADU architects focus mainly on the design phase, design-build contractors handle both design and construction, offering a more integrated solution. Depending on your budget and project complexity, you may opt for a firm that specializes in ADU architecture or a full-service company that covers all phases of the project.

Design-Build Firms
If you’re looking for a more integrated approach, consider hiring a design build contractor instead of an architect. Design-build companies handle both the design and construction phases of your ADU, offering a streamlined process and better communication between the design and build teams. These companies often employ in-house architects or draftsmen who are familiar with ADU architecture. This option can be more cost-effective since they manage the entire process and ensure the designs are realistic within your budget.
