What Is the Ideal Lot for an ADU in Colorado?

Understanding Zoning Laws and Regulations

Variance Requests

Even if your lot doesn’t initially meet zoning requirements, applying for a variance can often provide a pathway to approval. Variances allow for exceptions to zoning rules, such as setback requirements or maximum square footage limits. An experienced design-build firm can help you navigate this process, ensuring your application is thorough and persuasive.

Evaluating Lot Size and Shape

1. Zoning Compatibility

Colorado’s zoning laws vary by municipality, and they play a significant role in determining whether your property can accommodate an ADU. The passing of House Bill 24-1152 has eased restrictions, but homeowners must still verify:

• Zoning Designation: Confirm your property’s zoning designations and associated regulations. Common designations include single-family or mixed-use residential zones.
• ADU Size Limitations: Many municipalities restrict ADU size to a percentage of the main house, typically around 50% but no larger than 1,200 square feet.
• Setback Requirements: These specify the minimum distance between the ADU and property lines, streets, and neighboring structures.

‍

2. Local Restrictions

Even with favorable zoning, additional restrictions may apply, including:

• Homeowner Association (HOA) Rules: While state laws now limit HOA powers to outright ban ADUs, they can still enforce design and aesthetic guidelines.
• Historic District Regulations: Properties within historic districts may face stricter design rules to maintain neighborhood character.

Working with an experienced design-build firm like Kindred Tiny Homes ensures compliance with all local regulations.

Evaluating Lot Size and Shape

1. Lot Size Requirements

While Colorado’s new ADU laws promote flexibility, certain practical considerations regarding lot size remain:

• Minimum Lot Size: Many municipalities require a minimum lot size of 5,000 square feet to build an ADU.
• Space for Setbacks: Ample room must exist to meet setback regulations without compromising the ADU’s usability.
• Outdoor Space: Adequate yard space enhances the livability of both the main home and the ADU, preserving a sense of openness.

2. Lot Shape and Configuration

The shape of your lot can influence the feasibility of ADU construction. Irregularly shaped lots may limit placement options, while narrow lots can pose challenges for meeting setback requirements. However, at Kindred Tiny Homes, we have builds that are optimized for narrow lots and can accommodate almost any property.

Accessibility Considerations

1. Accessibility of Build Site for Equipment

Ensuring that the build site is accessible for construction equipment is a critical consideration for ADU projects. Factors like narrow driveways, steep slopes, or dense vegetation can complicate the delivery of materials and equipment. Design-build firms excel in planning for these challenges, using strategies like crane delivery or compact machinery to keep the project on track. Addressing these logistical hurdles early prevents delays and ensures a smoother construction process.

2. Easements and Utility Access

Easements can significantly impact your ability to build an ADU. You’ll need to ensure:

• Utility Easements: Avoid building over utility lines or areas designated for public utilities.
• Access Easements: If the ADU is located at the rear of the property, ensure there are no easements that would interfere.
• Utility Connections: Proximity of the build site to utility connections is an important factor to always consider. At Kindred Tiny Homes, our ADU Development Directors always look for the most efficient and cost effective avenue for our clients.

3. Efficient Material Delivery Planning

Ensuring efficient material delivery is a key consideration for a successful ADU project. Challenges like narrow roads, lack of staging areas, or shared driveways can complicate the logistics of transporting and staging materials to your build. Design-build firms plan proactively for these scenarios, utilizing their inventory and compact equipment to minimize disruption and keep your project on schedule.

Utilities and Infrastructure

1. Sewer and Water Source Considerations

Whether your lot is connected to city utilities or relies on a well and septic system is a critical factor in determining the feasibility of an ADU. Properties connected to municipal sewer and water systems often have an easier time meeting utility requirements for ADUs, but this can depend on the capacity of existing lines. Conversely, lots with a well and septic system may require:

• Septic System Expansion: Adding an ADU might mean upgrading your current septic system to handle the increased load.
• Water Testing and Capacity Checks: Ensure the well can supply adequate water for both the main house and the ADU.
• Permits and Compliance: Additional permits may be required to modify or expand these systems to meet state and local health codes.

2. Cost Considerations for Utility Upgrades

Upgrading utilities can significantly impact your budget. For example:

• Water and Sewer Line Upgrades: Adding new connections may cost between $5,000 and $35,000, depending on the distance and complexity.
• Electrical Panel Upgrades: Increasing capacity for an ADU often involves installing a new sub-panel, which can cost $2,000 to $5,000.
• Gas Line Adjustments: Extending or upgrading gas lines can range from $1,500 to $3,500, depending on the scope of work.

Understanding these costs upfront helps in planning your project effectively.

3. Utility Capacity

Your property’s existing utility systems must be able to accommodate the added load of an ADU. This includes:

• Water and Sewer Connections: Confirm that your main home’s water and sewer lines can support an additional unit. Otherwise, upgrades may be required.
• Gas and Electric: Check whether your current electrical panel and gas line can handle the increased demand. Adding a sub-panel or upgrading your existing system may be necessary.

4. Drainage and Grading

Proper drainage is essential for ensuring your ADU’s longevity. Assess:

• Flood Zones: Building in a flood-prone area may require special precautions like elevated foundations.
• Slope and Grading: Lots with significant slopes may need additional site preparation to ensure a stable foundation.

Orientation and Design Considerations

1. Optimizing Multi-Use Spaces

When planning your ADU, consider incorporating multi-functional spaces that enhance usability without increasing the overall footprint. For instance:

• A dining area that doubles as a workspace.
• Built-in furniture solutions, such as murphy beds or foldable tables.
• Storage systems designed to maximize limited square footage.

These design choices not only improve functionality but also increase the ADU's appeal for rental purposes or family use. A reputable design-build firm can help you incorporate these features seamlessly into your plan.

1. Sunlight and Privacy

The positioning of your ADU can significantly impact its usability and aesthetics:

• Maximizing Sunlight: Orient the ADU to take advantage of natural light for energy efficiency and comfort.
• Preserving Privacy: Consider placement that minimizes intrusion on your main home and neighboring properties.

2. Aesthetic Integration

Blend the ADU seamlessly with your property by aligning its design with your main home. This not only satisfies potential HOA guidelines but also enhances the property’s overall value.
