Choose your city

Missouri's climate is a major consideration for ADU projects. Winter cold requires proper foundation insulation and robust heating systems. Summer heat and humidity demand good ventilation. Severe weather, like thunderstorms and occasional tornadoes, means sturdy construction is essential. Building is best done during the milder seasons of spring and fall. We work with builders who understand these local conditions to ensure a durable ADU.

Common questions

What are the downsides of ADUs in Missouri?

Downsides can include preparing for extreme weather events like heavy snow, ice storms, and tornadoes. Ensuring adequate insulation for both cold and heat is crucial. Local zoning can also present challenges. We help you plan for these factors.

What is the cheapest way to build an ADU unit?

The cheapest ADU unit often involves a simple, box-like design with minimal architectural complexity. Opting for a detached backyard cottage is usually more affordable. Using standard, readily available materials helps reduce costs. We focus on efficient, budget-friendly construction.

What does ADU stand for?

ADU stands for Accessory Dwelling Unit. It is a secondary, independent living space on a single-family home lot. ADUs can be detached or attached to the main house. They provide flexible housing options in cities like St. Louis.

Are ADUs allowed in Missouri?

Yes, ADUs are permitted in many Missouri cities, but local regulations are key. Each municipality has its own rules regarding size, placement, and permitting. We help you understand these specific requirements. Many areas are embracing ADUs for housing growth. We can guide your project.

What is the most expensive part of building an ADU?

The most expensive elements are typically the foundation and connecting utilities like water, sewer, and electricity. Framing, roofing, and any custom exterior or interior finishes also add significantly to the total cost. We help you budget for these major expenses.

How do I find a good builder for my ADU unit?

Look for builders with experience in Missouri's climate and building codes. Ask for references and review their past ADU projects. Ensure they are familiar with the local permitting process in your city. We can help you find qualified professionals.
