  • We were looking at ways to invest our money. My wife and I thought, why don't we build an ADU for rental income? Also, someday we can move into it. So it has multiple purposes.

  • We decided to build an ADU because our family's property is a big lot. That's hard to find these days, especially with the cost of housing. Plus we are closer to my mom.

FAQs: Working with SnapADU

What is your typical process for working with a new customer?

Once you fill out a brief Project Assessment, we get into the details with you right away to make sure your project is feasible and that your vision is aligned with your budget. Read about our overall process from the time we first interact to the time we hand you the keys. Also read about our user-friendly interface, BuilderTrend, where we manage your entire project.

Do you provide free consultations?

Yes, we are happy to answer feasibility questions, provide ballpark estimates, and get into details quickly about your property specifics so you can decide if an ADU project is right for you and, more specifically, if you’d like to work with us.

Do you design custom plans?

Yes! We offer custom, standard, and semi-custom plans. Read more about custom ADUs and custom ADU floor plans, and check out all our standard floor plans as a jumping off point.

Do I need to have plans before I start with SnapADU?

No, in fact we offer the most competitive pricing if you pick from our standard plans, or work with us to customize an existing plan to suit your needs. You can also provide us with a sketch of your ideas or your “wish list” and we will design something custom for you.

Do you offer just plans & permitting, or only design-build?

Our primary focus is on design-build projects, providing an integrated, end-to-end experience for our clients. While we don’t exclusively offer design & permitting services, if you’re open to considering the complete design-build approach, we’re here to guide you every step of the way. And why choose a design-build general contractor like SnapADU over separate teams of professionals? Here’s a snapshot of the benefits:

  • Accountability: Our singular focus on design-build ensures seamless project execution. We are entirely accountable, aligning with the commitments made during the feasibility study.
  • Transparent Budgeting: Our approach centers around clear budgeting. We provide an unambiguous view of the complete costs right from the outset.
  • Guaranteed Price: With SnapADU, you get a fixed build price. This ensures budget predictability with no surprises.
  • Efficiency: Our in-house permitting team ensures that the project moves swiftly and efficiently, eliminating potential delays that can arise from multiple handoffs.
  • Quality: A collaborative, unified team means that the end result will be of the highest standard.
  • Cost Savings: A significant number of projects encounter cities that may misinterpret ADU regulations, leading to unnecessary costs. Our seasoned team is well-equipped to advocate for you, ensuring you aren’t paying more than you need to.

What work does SnapADU do in-house?

We are a licensed general contractor and provide a design/build service, meaning you work with us for your entire project and we are fully accountable. We will be on point for getting the job done during design, permitting and in the field. We subcontract out trades like concrete, framing, drywall, plumbing, electrical, HVAC, tile & stucco. We also partner with select septic companies, geotechnical engineers, civil engineers, and structural engineers for the site planning phase of the work. All the rest of the work is done in-house by our team, including design & permitting.

What areas do you serve?

We build ADUs throughout Greater San Diego, including Oceanside, Carlsbad, Encinitas, Vista, San Marcos, Escondido, Solana Beach, Del Mar, Poway, La Mesa, El Cajon, Chula Vista and surrounding areas. See our service area map.

What construction type does SnapADU use?

Our ADUs are “stick built” construction and are not prefab ADUs, mobile or manufactured homes. All of our ADUs are built on site using conventional framing methods, though we utilize some offsite processes that improve our quality control and timeline. We regularly evaluate new technology to make sure we are offering a competitive product.

Do you handle remodels? What about landscaping or other backyard projects?

In a world where versatility is often praised, there’s still immense value in specialization. We have made a deliberate decision to focus solely on detached ADU (Accessory Dwelling Unit) design and build for several key reasons:

  1. Expertise Through Specialization: By dedicating ourselves exclusively to detached ADUs, we’ve refined our skill set to become true experts in this niche area. This enables us to maintain the highest quality standards and keep up with the latest best practices, ensuring our clients receive nothing but the best. From initial planning and design to the final stages of construction, our in-house team collaborates seamlessly, ensuring a cohesive and efficient project flow.

  2. External Elements Can Be Managed Post-Completion: While elements like landscaping, patios, or other auxiliary structures can enhance the overall aesthetic and functionality of a property, they are not integral to the ADU construction process. These components can be executed after our work is done. We’ve found that many homeowners have preferred vendors for such tasks or may even choose to undertake some projects DIY-style. By allowing homeowners the flexibility to manage these elements separately, they often find opportunities for cost savings and personalized touches.

  3. Home Additions and Remodels Present Unique Challenges: Working on additions or remodels is fundamentally different from constructing a detached ADU. Such projects require extensive coordination with existing structures and conditions, which can be unpredictable and may lead to extended timelines and unforeseen expenses. Our commitment to transparency, predictability, and excellence means we avoid venturing into areas that could compromise these values.

While there are countless avenues in the world of construction and design, we’ve found our passion and expertise in ADUs — and we’re committed to being the best in this space.

Does SnapADU provide a warranty?

Yes, SnapADU provides comprehensive warranties as part of our construction agreement. Our commitment includes:

  • 1-year Full-Service Warranty on all workmanship and materials we manage or procure, ensuring adherence to the NAHB Residential Construction Performance Guidelines – Fifth Edition. This warranty covers defects not caused by normal wear and tear or homeowner neglect.
  • 2-year Full MEP Warranty on all mechanical, electrical, and plumbing (MEP) systems, including solar/photovoltaic systems
  • 10-year Structural Warranty against structural defects, contingent on our adherence to approved plans and specifications.

A soils report is an optional step in most jurisdictions. Declining a soils report means that no soils compaction testing will be performed by a Geotechnical Engineer, and the ADU will be built to the most stringent UBC design standards & thresholds. In such cases when a soils report is declined, SnapADU will not be responsible for issues stemming from insufficient soil conditions.
