Building an accessory dwelling unit is tailored to your unique vision. Whether it's an in-law suite or an age-in-place addition, work with a design/build builder who knows the local rules.

ADUs can be attached, detached, or built over a garage. They usually include a living room, bedroom, kitchen, and bath with a separate entrance to fit your home and lifestyle.

Detached ADUs offer a separate living space on your property.

• They can range from 450 to 1500 sq ft, depending on local rules.
• A design/build contractor with local know-how can help navigate these rules and make the most of your space.

Attached ADUs blend with your home, like an in-law suite or age-in-place addition.

• They usually max out at around 800 sq ft and match your home's style.
• They often include a lockable entrance and shared spaces such as an entry or foyer, and can even be built above a garage.

With careful planning and expert help, both types of ADUs can make your home more flexible and add real value.

One of the most important steps before starting your accessory dwelling unit (ADU) project is understanding what your local town allows. Rules around size, placement, and permitting can vary significantly between towns—even within the same county.

To help you move forward with clarity, here’s a quick overview of the five service areas we work in, each with a link to its official ADU or zoning guidelines:

• Cary – Cary recently expanded its ADU ordinance, now allowing detached units in most residential areas and increasing the size limit up to 50% of the main home.
• Raleigh – Raleigh’s updated zoning makes it easier than ever to permit ADUs with a dedicated fast-track review system.
• Wake Forest – ADUs are covered under the Unified Development Ordinance, with detailed guidance available for homeowners in and around Wake County.
• Holly Springs – Local regulations treat ADUs as accessory structures, and permits are required for design and utility updates.
• Apex – Apex offers clear zoning language for both attached and detached ADUs, often subject to lot size and placement criteria.

Checking your town’s ordinances early in the planning process can save you time, money, and frustration. We’ll help interpret the local codes and make sure your design aligns with what's allowed—so your ADU vision becomes a fully permitted reality.

Not every contractor is equipped to handle the complexity of an accessory dwelling unit. ADUs involve zoning compliance, permitting, design coordination, and construction experience that goes far beyond basic home repairs. Understanding the difference between a licensed general contractor and a handyman can help homeowners avoid costly mistakes early in the process, especially when building in Cary or Raleigh.

Many homeowners assume any contractor can manage an ADU, but the reality is different. This is where understanding the difference between a general contractor and a handyman in Cary becomes critical for projects that require permits, inspections, and coordination across multiple trades.

When planning for more space, homeowners often compare an ADU with a traditional home addition. Both options can increase square footage and long-term value, but they serve different needs. An addition keeps everything under one roof, while an ADU offers independence, flexibility, and privacy—often ideal for in-law suites, caregivers, or multigenerational living.

If you’re weighing these options, understanding the practical differences in layout, cost, and long-term use can help guide your decision. This comparison of ADU vs. home addition explains when each approach makes the most sense for Raleigh-area homeowners.

Selecting the right ADU builder is one of the most important decisions you’ll make during the planning process. Experience with local zoning rules, permitting requirements, and ADU-specific construction details can make the difference between a smooth project and one filled with delays and revisions.

Homeowners evaluating builders should look beyond price alone and focus on proven ADU experience, clear communication, and an established process. This guide on choosing the right ADU contractor in Raleigh outlines what to look for and which questions to ask before moving forward.

Even well-planned ADU projects can encounter delays or budget overruns due to avoidable mistakes. Common issues include misunderstanding zoning requirements, underestimating utility upgrades, or selecting designs that don’t support long-term needs such as accessibility or aging in place.

Before moving forward, it helps to understand where homeowners most often go wrong. Learning about common ADU mistakes to avoid can help you plan with confidence and avoid setbacks that slow down construction or increase costs.

 Q: What is the typical timeline for building an ADU?
A: Generally, building an ADU takes about 6 to 12 months from start to finish. This period covers planning, permits, and construction, but the exact timeline can vary based on the project's scope and local regulations.

Q: Is my property eligible for an ADU in Wake County, NC?
A: Your property must be zoned for single-family residential use to be eligible for an ADU. For more details, use the Wake County iMAPS tool as a resource to check your property's zoning.

Q: What is the best foundation for an ADU?
A: The best foundation for an ADU depends on your property’s soil conditions, local codes, and design needs. Many homeowners choose a concrete slab for durability, while a crawl space or pier-and-beam design may work better for uneven ground.
