Accessory Dwelling Units (ADUs) are becoming increasingly popular as a cost-effective solution for adding living space or generating rental income. However, the cost of building an ADU can be daunting. If you’re wondering how to build an ADU for cheap without sacrificing quality, you’re in the right place!
In this guide, we’ll walk you through budget-friendly tips and strategies to help you create a functional, attractive, and affordable ADU.
1. Start with a Clear Plan
I recently worked with a couple who had been dreaming of building an ADU on their property for years. They wanted to create a comfortable living space for their aging parents, but they were concerned about the potential costs.
When they approached me, their biggest question was how to build an ADU for cheap without compromising on quality or functionality. I reassured them that with careful planning and a clear budget, their vision could become a reality.
We began by outlining their specific needs and goals for the ADU. By having a clear roadmap from the start, we were able to make strategic decisions that kept costs down while ensuring the final product was exactly what they envisioned.
In short, you need to have a clear plan when trying to figure out how to build a pocket-friendly ADU. It helps you stay focused on your budget and ensures that every decision you make aligns with your financial goals.
Define Your Purpose and Goals
Ask yourself what you intend to use the ADU for: Will it be a rental unit to generate additional income? Or perhaps a place to live for aging parents or adult children? Your goals for the ADU will influence everything from the design and layout to the features you prioritize and the budget you set.
For instance, if your goal is to rent out the ADU, you might include features that appeal to tenants, such as a separate entrance, privacy features, and durable, low-maintenance materials.
On the other hand, if you’re building the ADU for family use, you might focus on comfort and customization, ensuring the space meets your family’s specific needs.
Set a Realistic Budget
Start by determining how much you can afford to spend on the project. Consider all potential costs, including design fees, permit costs, construction materials, labor, and finishing touches.
Once you have a general budget in mind, break it down into specific categories. Allocate funds for each phase of the project, such as site preparation, foundation, framing, electrical, plumbing, and interior finishes.
Be sure to include a contingency fund of at least 10-15% of your entire budget to cover unforeseen expenses. This cushion can be a lifesaver if unexpected issues arise during construction, like discovering outdated wiring or needing additional permits.
Engage with Professionals Early
Architects, designers, and contractors can offer expert advice on how to optimize your design for cost savings. They can also identify potential issues before they become problems and ensure that your ADU meets all necessary codes and regulations.
Having professionals involved from the outset can also help you stay on schedule and within budget. They can help you with everything from drafting plans and obtaining permits to managing the construction process.
2. Opt for a Simple Design
A simple, minimalist design not only reduces construction costs but also streamlines the entire building process, leading to fewer complications and delays. Here’s how opting for a simple design can help you save money:
Embrace a Rectangular or Square Layout
A rectangular or square floor plan is one of the most cost-efficient designs for an ADU. These shapes are easier to build because they involve fewer angles and require less material for construction.
Complex shapes, on the other hand, often require more intricate framing, additional materials, and specialized labor, all of which can significantly increase your costs.
Simplify the Roof Design
The roof is one of the most expensive components of any building, and the more complex the design, the higher the cost. A simple, single-pitch (shed) roof or a gable roof is much more affordable than a multi-pitched or hip roof.
Moreover, a flat roof can also be a budget-friendly option, particularly for a modern, minimalist ADU. However, be mindful of the climate in your area—flat roofs are more susceptible to water accumulation, which can lead to maintenance issues if not properly designed.
Plan for Future Upgrades
If you’re working with a tight budget, consider designing your ADU with future upgrades in mind. Opt for a simple design to save money upfront and leave room for enhancements later when your budget allows.
For instance, you might choose to install basic fixtures and finishes initially, with the option to upgrade to higher-end materials in the future. Additionally, you could plan for the eventual addition of a second bathroom or a small kitchenette without needing to demolish the entire structure.
3. Choose Affordable Materials
The key to staying within your budget while still achieving a high-quality finish is to select materials that are both affordable and durable. Here are some strategies and tips to help you make smart material choices:
Exterior Materials
You can start saving money by choosing budget-friendly materials for your ADU’s exterior. For example, vinyl siding is a good choice for its affordability, low maintenance, and durability. You can choose from an array of colors and styles and achieve a customized look without the high price tag associated with wood or brick.
Another option is fiber cement siding. While slightly more expensive than vinyl, it offers you a balance between cost and longevity. It’s resistant to fire, pests, and rot, making it a durable choice that can save money on repairs in the long run.
Moreover, if you want to add a natural touch, consider using engineered wood siding. Its appearance resembles real wood, but it’s less expensive and more resistant to weathering and termites.
Interior Materials
Inside your ADU, you can choose from numerous affordable yet stylish materials. For flooring, laminate and luxury vinyl planks (LVP) are excellent alternatives to hardwood. These materials mimic the appearance of wood or stone but at a fraction of the cost. They are also durable, easy to install, and don’t require much maintenance.
When it comes to countertops, laminate and solid surface materials like Corian are more budget-friendly than granite or quartz. Available in a wide range of colors and patterns, you can achieve the aesthetic you want without overspending. Additionally, they’re easy to clean and maintain, making them practical for everyday use.
For walls, instead of opting for high-end paint or wallpaper, consider using standard drywall with a fresh coat of paint. You can create accent walls with more affordable options like shiplap or beadboard to add character and texture.
Shopping Tips
Consider shopping at local building supply stores, salvage yards, or reclaimed material suppliers. These places often have significant discounts on high-quality materials that might have minor imperfections or are overstocked items.
You can also look for online marketplaces where contractors and builders sell excess materials at a reduced price.
Another way to save is by timing your purchases during sales events or by buying in bulk. Many suppliers offer discounts for larger quantities, so if you’re purchasing materials for the entire ADU at once, you might be able to negotiate a better price.
4. Consider a Garage Conversion
A garage conversion typically costs less than building an ADU from the ground up because the basic structure is already in place. This means you can save on several major construction expenses, such as:
- Foundation Work: A large part of the cost of building an ADU involves laying the foundation. With a garage conversion, the foundation is already there, which can save you thousands of dollars.
- Framing Costs: Since your garage already has walls and a roof, you can avoid the high costs associated with framing a new structure.
- Utility Connections: In many cases, garages are already connected to your home’s electrical system and possibly water lines as well.
While upgrades may be necessary, these existing connections can reduce the cost of hooking up utilities to your new ADU.
Considerations Before You Start
While garage conversions are cost-effective, you need to keep certain things in mind before going for this option. First, you’ll need to decide whether you can afford to lose your garage space for storage or parking.
Additionally, not all garages are ideal candidates for conversion, especially if they are in poor condition or located in areas prone to flooding. Thus, make sure to have your garage checked out by a professional before turning it into an ADU.
Lastly, ensure your garage meets local building codes for ADUs, including requirements for insulation, ventilation, and egress.
FAQs
