As Denver’s housing market continues to grow, homeowners are looking for creative solutions to maximize their property’s potential. One such solution that has gained significant attention in recent years is the Accessory Dwelling Unit (ADU). Whether you want additional living space for guests, a rental unit for passive income, or a separate area for multi-generational living, a custom ADU is an excellent choice.

At Mile High Construction, we specialize in custom ADU construction in the Denver metro area. With a wealth of experience and a passion for quality craftsmanship, we help homeowners design and build ADUs that perfectly suit their needs and property. Our team of expert accessory dwelling unit contractors understands the intricacies of Denver’s zoning laws, building codes, and neighborhood requirements, ensuring a seamless construction experience from start to finish.

What is a Custom ADU?

Custom vs. Pre-Designed ADUs

When it comes to Accessory Dwelling Units (ADUs), homeowners have two primary options: custom-built ADUs and pre-designed models. While pre-designed ADUs can be a quicker, more affordable option, a custom ADU offers flexibility and personalization to meet your specific needs. At Mile High Construction, we believe in crafting ADUs that perfectly match your lifestyle, property, and design preferences.

A custom ADU gives you the opportunity to work closely with our team of designers and builders to ensure that your new space meets your exact specifications. From layout and design to finishes and functionality, every aspect of your custom ADU is tailored to you. Whether you’re building a detached unit in the backyard or converting your existing garage, the possibilities are endless with a custom solution.

Types of Custom ADUs

There are several types of custom ADUs that can be built on your property, each with its own benefits. Here are some of the most popular options:

Detached ADUs

Detached ADUs are stand-alone structures built separately from your main home. These are ideal if you want complete privacy or need extra space without altering your existing living space. They can be designed as small homes, studios, or even mini-apartments, providing ultimate flexibility.

Attached ADUs

Attached ADUs are units that are added directly to the existing structure of your home, such as a basement or second story. These are perfect for homeowners who want to expand their living space without needing additional land. They can seamlessly integrate with your home while offering privacy and independence.

Garage Conversion ADUs

If you have an unused or underutilized garage, converting it into an ADU can be an excellent way to add space. Garage conversions are typically more affordable than building from the ground up, and they make use of existing structures and utilities.

Basement ADUs

Basement ADUs utilize your home’s lower level and can be a great option if you have the space to spare. With proper design and finishing, a basement ADU can provide a comfortable and private living area with easy access to your main home.

Why Customization Matters

The main benefit of building a custom ADU is the ability to tailor it exactly to your needs. Unlike pre-designed units, custom ADUs allow you to make decisions on the layout, functionality, size, and aesthetic of the space. Whether you’re planning to use your ADU as a rental property, a guest house, or a home office, Mile High Construction will help you create a space that enhances both the function and the value of your property.

The Benefits of Custom ADUs for Denver Homeowners

Additional Rental Income

One of the main reasons homeowners in Denver opt for custom ADUs is the potential for rental income. With the city’s housing market growing and rental prices on the rise, a custom ADU can provide a steady income stream. Many homeowners turn to accessory dwelling units as a way to supplement their mortgage payments or to earn income by renting out the space long-term or on platforms like Airbnb.

By building a custom ADU with Mile High Construction, you ensure that the unit is designed to meet local rental requirements, which can increase its desirability and help you achieve a competitive rent rate in Denver’s rental market. Whether it’s a studio apartment, a one-bedroom unit, or a two-bedroom unit, we can help you create a space that attracts high-quality tenants.

Increased Property Value

A custom ADU can significantly increase the value of your property. Whether you’re planning to rent out the unit or simply add more space for family use, a well-designed ADU can make your property more appealing to future buyers. Homebuyers in Denver are increasingly seeking properties with additional living spaces, making an ADU a smart investment for long-term value.

At Mile High Construction, we understand the local market trends and can help you design and build an ADU that will maximize the return on your investment. By considering the layout, finishes, and functionality of the ADU, we ensure it aligns with your home’s aesthetic and increases overall property value.

Multi-Generational Living

In today’s world, many families are choosing to live together to save money or provide support for aging parents or adult children. A custom ADU is an excellent solution for multi-generational living, offering a private living space while still maintaining close proximity to the main home. Whether it’s a small apartment for grandparents or a private suite for an adult child, a custom ADU allows your family to stay together while maintaining privacy.

Mile High Construction specializes in designing ADUs that are not only functional but also comfortable and stylish. We can help you create a space that accommodates different family dynamics, ensuring everyone has the space they need.

Guest Suite or Home Office

In addition to offering rental income and family living solutions, a custom ADU can serve as a versatile space for personal use. Homeowners are increasingly choosing to build ADUs to accommodate guests or as a quiet retreat for a home office.

The rise of remote work in Denver means many homeowners are looking for ways to create dedicated office space without taking up room in the main house. A custom ADU can offer the perfect solution—separate from the distractions of the household and designed with your work needs in mind.

Sustainable Living

Sustainability is becoming a priority for many homeowners, and custom ADUs are an excellent way to reduce your environmental footprint. At Mile High Construction, we can design your ADU with eco-friendly building materials, energy-efficient systems, and sustainable construction practices. From using solar panels to installing high-efficiency appliances, your custom ADU can be built to align with your sustainability goals, reducing both energy consumption and environmental impact.

Choosing the Right ADU Construction Company in Denver

When it comes to building a custom ADU, selecting the right ADU construction company is crucial for ensuring a smooth and successful project. In the Denver metro area, many construction companies offer a range of services, but not all have the specialized expertise required for ADU projects. To help guide you in making the best choice, here are the key factors to consider when choosing an ADU construction company, like Mile High Construction:

Experience and Expertise in ADU Construction

ADU construction requires specific knowledge of zoning laws, building codes, and design requirements that are unique to accessory dwelling units. It’s important to choose an ADU construction company with proven experience in this niche area. At Mile High Construction, we specialize in building custom ADUs and have extensive knowledge of the local Denver market, including permitting, design guidelines, and construction methods specific to ADUs.

Our team understands how to navigate Denver’s unique zoning regulations and can ensure that your ADU complies with all local requirements, including setbacks, height restrictions, and parking regulations. Our expertise guarantees that your ADU will be built to code and completed on time and within budget.

Local Knowledge of Denver’s Building Codes and Zoning Regulations

Denver has specific regulations governing the construction of ADUs, which can vary by neighborhood. For example, certain areas of Denver may have different height restrictions, parking requirements, or design limitations for accessory dwelling units. It’s essential to work with a construction company that has in-depth knowledge of these regulations to avoid potential issues during the permitting process.

At Mile High Construction, we are intimately familiar with Denver’s building codes and zoning laws. We help guide you through the permitting process, ensuring that your ADU project complies with all necessary codes, making the construction process smoother and faster.

Transparent and Open Communication

Communication is key to a successful construction project. From initial consultation to final inspection, clear and consistent communication ensures that everyone is on the same page and that your project runs smoothly. When you work with Mile High Construction, you can expect frequent updates on the status of your project, with the ability to ask questions and express concerns throughout the process.

Our team will work with you closely to understand your needs, preferences, and goals for the ADU. We make sure you’re involved in every step, from design discussions to material selections, and we keep you informed about any changes or delays.

Proven Track Record of Successful ADU Projects

Before choosing an accessory dwelling unit contractor, it’s important to review their previous projects and client feedback. Ask for references or case studies of past ADU projects they’ve completed. At Mile High Construction, we have a portfolio of successful custom ADU projects throughout the Denver metro area. We pride ourselves on the quality of our work and the satisfaction of our clients.

Feel free to ask us for testimonials, project photos, and even to speak with previous clients. We are confident that our track record of delivering high-quality, functional, and beautiful ADUs speaks for itself.

Budget and Timeline Transparency

Building a custom ADU is an investment, and it’s important to have a clear understanding of costs and timelines from the outset. When selecting an ADU construction company, ensure they provide detailed, accurate cost estimates and timelines. At Mile High Construction, we offer transparent pricing, so you know exactly what to expect before the project begins. We also provide a comprehensive timeline, ensuring that your ADU is completed on time without compromising quality.

Steps to Building Your Custom ADU in Denver

Building a custom ADU in the Denver metro area is a multi-step process that requires careful planning, design, and construction. At Mile High Construction, we guide homeowners through each phase of the ADU construction process to ensure a seamless and successful project. Below is a breakdown of the essential steps involved in building your dream accessory dwelling unit.

Step 1: Assess Your Property and Budget

The first step in building a custom ADU is evaluating your property to determine if it’s suitable for an ADU. At Mile High Construction, we help you assess the available space on your property, considering zoning laws, setbacks, and any other site-specific factors that may affect your ADU design.

Once the property has been evaluated, it’s time to set a realistic budget. The cost of building an ADU can vary greatly depending on the size, design, and materials used. We’ll work with you to set a budget that aligns with your vision, making sure that we provide cost-effective solutions without compromising quality.

Step 2: Design Your Custom ADU

Designing a custom ADU is an exciting step where you can bring your vision to life. Whether you’re looking for a cozy studio, a spacious one-bedroom apartment, or a two-story guesthouse, Mile High Construction will collaborate with you to create a design that fits your needs and complements your existing property.

Our design team works with architects and engineers to develop blueprints that not only match your aesthetic preferences but also comply with Denver’s building codes and zoning requirements. We ensure that the design of your ADU maximizes the available space, making it both functional and comfortable.

Step 3: Obtain Permits and Approvals

Before construction can begin, your custom ADU must be approved by local authorities. This is where the permitting process comes in. Denver has specific requirements for accessory dwelling units, including permits for building, plumbing, electrical, and sometimes even landscaping.

At Mile High Construction, we handle all aspects of the permitting process. Our team ensures that all necessary applications are submitted and approved so that construction can proceed without delay. We know the ins and outs of Denver’s regulations and can guide you through the complexities of obtaining the required permits.

Step 4: Construction of Your Custom ADU

Once the permits are in place, we begin the construction phase. This is when your vision starts to take shape! Our team at Mile High Construction ensures that every step of the construction process is handled with care and precision. We start with site preparation, including excavation and foundation work, followed by framing, roofing, plumbing, and electrical installation.

We use only high-quality materials and trusted techniques to ensure your custom ADU is built to last. Throughout the construction process, we keep you updated on progress and any potential changes to the schedule or budget.

Step 5: Final Inspection and Walkthrough

Once the construction is complete, a final inspection is conducted to ensure that your custom ADU meets all Denver building codes and regulations. At this stage, we walk through the ADU with you, checking for any final touches and ensuring everything is up to your standards.

If there are any adjustments or changes required, we’ll make sure they’re addressed before we consider the project complete. Our commitment to quality means we ensure that your accessory dwelling unit is finished to the highest standards.

Cost of Building a Custom ADU in Denver

Building a custom ADU in the Denver metro area can be a significant investment, but it offers great potential for increasing your property value and generating rental income. The total cost of your accessory dwelling unit will vary depending on several factors, including the design, materials, size, and any additional features you choose to include. At Mile High Construction, we provide detailed cost estimates to help you plan your ADU project within your budget. Here’s an overview of the key factors that affect the cost of building a custom ADU in Denver:

Factors Affecting ADU Construction Costs

Size and Design

The size of your custom ADU is one of the most significant factors that will impact the cost. A larger unit will require more materials, labor, and time to build. Additionally, the complexity of the design, including the number of rooms, custom features, and style, will influence the final price.

Materials and Finishes

The quality of the materials and finishes you choose will directly affect the cost of your ADU construction. For example, premium flooring, high-end appliances, and custom cabinetry will raise the overall price. However, choosing more affordable yet durable materials can help you keep costs down while still achieving the desired look and functionality.

Site Preparation and Utilities

If your property requires significant grading, excavation, or utility installation (such as plumbing, electrical, or sewage systems), this will add to the cost. At Mile High Construction, we assess your site before construction begins to give you a clear idea of the costs involved in site preparation.

Permits and Fees

In Denver, building an ADU requires various permits, including those for zoning, building, and inspections. Permit costs can vary depending on the size and complexity of the accessory dwelling unit, and it’s essential to factor these into your budget. Mile High Construction handles all the necessary permits for you, so you won’t have to worry about these costs.

Tips for Managing ADU Construction Costs

Plan Ahead

One of the best ways to keep your ADU construction project on budget is by thoroughly planning from the beginning. Work closely with your contractor, like Mile High Construction, to establish a clear design, timeline, and budget before breaking ground.

Select Cost-Effective Materials

While you may be tempted to go for premium materials, there are cost-effective options that don’t compromise quality. Consider materials like laminate instead of hardwood or energy-efficient windows that can reduce long-term costs.

Expect the Unexpected

During construction, there are often unforeseen challenges, such as delays, additional site work, or unexpected permit issues. Make sure to set aside a contingency budget (typically 10-20% of the overall project cost) to handle any unexpected expenses.

Common Mistakes to Avoid When Building a Custom ADU

Building a custom ADU is an exciting process, but it’s important to avoid common pitfalls that could affect the success of your project. At Mile High Construction, we’ve seen many homeowners make mistakes that could have been easily avoided. Here are some of the most common mistakes to watch out for:

Not Understanding Zoning and Permit Requirements

One of the biggest mistakes homeowners make when building a custom ADU is not fully understanding the zoning regulations and permitting process. Denver has specific zoning laws that dictate where ADUs can be built and the size, design, and functionality allowed. Failing to comply with these regulations can lead to costly fines, delays, or even the inability to complete the project.

Mile High Construction is experienced in navigating Denver’s zoning laws and permits for accessory dwelling units. We ensure that your project complies with all the necessary requirements, so you don’t have to worry about issues later down the line.

Underestimating the Budget

It’s easy to get carried away with ideas for your custom ADU, but underestimating the budget can lead to financial strain. Many homeowners fail to account for site preparation costs, permits, or unexpected delays, leading to higher-than-expected expenses.

At Mile High Construction, we help you develop a realistic budget from the outset and provide detailed cost breakdowns throughout the project. By planning for potential unexpected costs, you can ensure that your ADU project stays within your budget.

Choosing a Contractor Without ADU Experience

Not all construction companies are experienced in building accessory dwelling units, and choosing a contractor without this specialized knowledge can lead to issues with design, permits, or quality. Look for a contractor like Mile High Construction, who has a track record of successfully completing custom ADU projects.

We specialize in ADU construction and are familiar with the specific needs and challenges that come with building these units. Choosing the right contractor ensures that your custom ADU project runs smoothly and efficiently.

Overlooking the Design and Functionality of the ADU

While the aesthetic design of your custom ADU is important, it’s equally crucial to focus on the unit’s functionality. Some homeowners prioritize looks over practicality, which can lead to a design that doesn’t suit their lifestyle or property.

At Mile High Construction, we work with you to create a design that is both beautiful and functional. Whether you’re building a rental unit, a guest house, or a home office, we ensure that the ADU meets all your needs while blending seamlessly with your existing home.

Building a custom ADU in the Denver metro area is an excellent way to maximize your property’s potential, whether you’re seeking additional rental income, a home office, or a separate living space for family members. At Mile High Construction, we specialize in custom ADU construction and guide homeowners through every step of the process—from design to completion.
