Designing Your ADU in Winter for a Spring Build

Why Denver Homeowners Should Start Planning Now
Building an Accessory Dwelling Unit (ADU) is one of the smartest ways to add value, flexibility, and long-term income potential to your property. But if you wait until spring to start planning, you’ll already be behind.
At Denver Dream Builders, we help homeowners design, permit, and build ADUs that fit their lot, their lifestyle, and their goals — and winter is the perfect time to start.
1. Winter Is the Ideal Time to Begin ADU Design
Most homeowners assume spring is the time to plan — but by then, contractors and city planners are buried in backlogs.
Starting your ADU design in winter gives you a huge head start:
- Faster permit approvals: Fewer projects in the queue mean quicker review times.
- More design availability: Architects and engineers have bandwidth for revisions and feasibility studies.
- Better scheduling: You’ll secure your contractor’s spring start date before everyone else.
Think of winter as your pre-construction season — when the paperwork, planning, and approvals move faster behind the scenes.
2. Start With a Feasibility and Zoning Review
Before any sketches or designs, it’s critical to confirm that your property qualifies for an ADU. Denver and surrounding cities (like Lakewood, Arvada, and Aurora) have different zoning codes that define where and how you can build.
During our feasibility phase, we:
- Review your zoning district (U-SU-A1, E-SU-D1x, etc.)
- Check lot size, setbacks, and height limits
- Identify utility access points and connection requirements
- Flag any historic overlays or HOA restrictions
This early research saves homeowners from costly redesigns and ensures your ADU concept is code-compliant from day one.
3. Winter Design Work Sets You Up for a Spring Build
A full ADU build involves several stages — and winter is when you want to knock out the first half:
- Site survey & measurements – 1–2 weeks
- Architectural & structural drawings – 3–4 weeks
- Zoning & code review – 2–3 weeks
- Permit submittal & revisions – 4–8 weeks
By starting those steps between December and February, you’ll be cleared for construction right as the weather turns in April or May — while most homeowners are still waiting on permits.
4. You’ll Secure Better Pricing and Scheduling
Demand drives pricing. In spring, when dozens of Denver homeowners flood the system with remodel and addition requests, contractors and material suppliers raise rates.
By finalizing your ADU design in winter, you can:
- Lock in off-season pricing before costs rise
- Reserve top crews while schedules are still open
- Prevent delays caused by back-ordered materials
For high-demand materials like lumber, windows, or electrical components, early ordering can shave weeks off your build timeline.
5. Tailor Your ADU Design to Your Property Goals
Every homeowner builds for a different reason. Some want a rental unit to generate passive income. Others need space for family, parents, or a home office.
During the design process, we help tailor your layout and budget to match your priorities:
- Rental income ADUs: Optimize for privacy, soundproofing, and separate entry.
- Family or in-law suites: Create universal design features like wider doors and step-free entries.
- Home offices or studios: Focus on insulation, lighting, and layout flexibility.
Winter’s slower pace gives you time to make thoughtful decisions without rushing through design revisions.
6. Understand the Difference Between Detached and Internal ADUs
If you’re just getting started, you’ll likely choose between these two ADU types:
- Detached ADU: A standalone structure, often in the backyard or over a garage.
- Internal ADU: A converted space within your main home — such as a basement, attic, or over-garage apartment.
Detached ADUs typically take longer to permit and build but offer more independence and higher rental potential.
Internal ADUs, like basement conversions, can often be completed faster — sometimes within 3–4 months.
We help homeowners evaluate both options and pick the one that fits your property and lifestyle best.
7. ADUs Add Long-Term Value and Flexibility
A well-built ADU can increase property value by 25–35%, depending on the neighborhood.
But the benefits go far beyond resale:
- Generate rental income to offset your mortgage
- Support multigenerational living
- Provide flexible work-from-home space
- Create future resale appeal for buyers seeking dual-living options
Starting design work early ensures your investment is ready to perform by summer.
