Accessory Dwelling Units (ADUs) are an excellent way for homeowners in Colorado Springs to add extra living space, generate rental income, or accommodate family members. With new regulations set to take effect in June 2025, ADU construction has become more flexible and accessible. Understanding the latest rules will help you determine the right size and design for your ADU.
What is an Accessory Dwelling Unit (ADU)?
An Accessory Dwelling Unit (ADU) is a self-contained residential unit that is either attached to or detached from a primary dwelling on the same lot. These units are commonly used as rental properties, guest houses, in-law suites, or additional living spaces. With updated Colorado Springs ADU regulations, homeowners now have greater flexibility in building and utilizing ADUs.
Maximum ADU Size in Colorado Springs (June 2025 Updates)
The City of Colorado Springs has introduced more accommodating ADU zoning laws, including increased size limits and relaxed zoning restrictions. Here are the updated guidelines:
- Detached ADU Size Limits: The maximum allowable size for a detached ADU is 50% of the primary dwelling’s square footage or 1,250 square feet, whichever is less.
- For primary dwellings smaller than 1,500 square feet, the ADU size is capped at 750 square feet.
- Setbacks & Placement:
- Side and rear setbacks: Minimum 5 feet from property lines.
- Front setbacks: Must comply with standard accessory structure placement rules.
- Height Restrictions:
- Detached ADUs can be up to 25 feet in height.
- Attached ADUs must adhere to the primary dwelling’s height restrictions.
- Short-Term Rentals Prohibited: Properties with ADUs cannot be used as short-term rentals (Airbnb, VRBO, etc.).
- No Additional Parking Required: The city has removed off-street parking requirements for ADUs, making it easier to build on smaller lots.
Choosing the Right ADU Size for Your Needs
Given these Colorado Springs ADU building codes, selecting the appropriate ADU size depends on your goals, property layout, and budget. Here are three common ADU size categories in Colorado Springs:
- Small ADUs (Under 400 Sq. Ft.)
- Ideal for studio apartments or guest houses.
- Cost-effective and easier to integrate into smaller properties.
- Suitable for single occupants or short-term visitors (within family use, since short-term rentals are not allowed).
- Mid-Sized ADUs (400-750 Sq. Ft.)
- Best for one-bedroom layouts.
- Provides more space for long-term rental tenants or family members.
- Easier to design with full kitchens and bathrooms while staying under zoning limits.
- Larger ADUs (750-1,250 Sq. Ft.)
- Maximizes rental income potential (long-term rental only).
- Accommodates two-bedroom floor plans.
- Requires more site planning but offers the most flexible living arrangements.
