Phase 1: Pre-Construction & Planning

Assembling Your Team

The foundation of a successful custom home project starts with choosing the right partner. Unlike traditional construction, where you separately hire an architect and then a general contractor, the design-build approach brings both teams together from day one. This integrated model gives you a single point of contact, streamlined communication, and a unified vision for your project.

When evaluating builders in Austin, look for licensed professionals with a proven track record in custom residential construction. Verify their credentials through the appropriate state licensing boards and review their portfolio to ensure their style aligns with your vision.

Securing Your Land & Conducting Site Assessment

Before design can begin, you need the right piece of land. Your property choice influences everything—from home orientation and foundation type to landscaping and utility access. When evaluating a potential lot in Austin, investigate zoning laws, property line setbacks, and neighborhood-specific restrictions. It’s also critical to confirm that city water, sewer, and power are readily available, or if you’ll need alternative solutions.

A professional design-build team can help you perform this due diligence, ensuring the land can truly accommodate your vision and your budget.

Phase 2: Design & Material Selection

Collaborating on Your Custom Design

This is where your dream home truly takes shape. You’ll work closely with architects and designers to finalize floor plans, elevations, and all the details that make a house a home. Gather inspiration through mood boards and photos that reflect your preferred style, lifestyle needs, and functional requirements.

Material and fixture selection happens during this phase—flooring, countertops, paint colors, lighting fixtures, and more. Making these choices thoughtfully and on time is one of the most impactful ways you can help ensure your project stays on schedule.

Understanding Austin’s 2024 Building Code Updates

It’s important to be aware that the City of Austin adopted the 2024 Technical Building Codes, which took effect July 10, 2025. Key updates relevant to custom homes include:

Air Conditioning Standards: All buildings must provide and maintain air conditioning systems that keep indoor temperatures no higher than 85 degrees and at least 15 degrees cooler than outside.
Energy Efficiency & EV Readiness: The updated codes introduce new energy efficiency standards for residential buildings and require electric vehicle (EV) charging infrastructure in new construction.
Wildfire Protection (WUI): Homes in designated Wildland-Urban Interface zones must meet more stringent construction requirements, such as fire-resistant materials and defensible space.

Your design-build team will ensure your home meets all these current codes, protecting your investment and your family.

Finalizing Blueprints & Specifications

Once designs are approved, comprehensive architectural documentation is prepared. These detailed plans and specifications serve as the blueprint for both permitting and construction, ensuring clarity and preventing costly misunderstandings during the build.

Phase 3: Permits & Approvals

Navigating Austin’s Permit Process

Before construction can begin, your home design must receive official approval from the City of Austin. Custom homes in Austin require a building permit, which ensures that your site plans adhere to local building codes and health and safety standards.

The City of Austin has streamlined the permit application process through the Austin Build + Connect (AB+C) portal, which allows you to apply online, upload documentation, and track your application status. The Development Services Department can be reached at 3-1-1 for general inquiries, or 512-978-4504 for appointments at the Permitting and Development Center.

Required Inspections in Austin

Your project will undergo a series of required inspections, including building inspections, environmental reviews, and site development inspections. These inspections verify that your home complies with all local Austin building codes and safety standards. Your design-build team manages this process, coordinating with city inspectors and ensuring all work is ready for review.

Securing Financing & Loan Approval

While permits move forward, you’ll also finalize your financing. Construction-to-Permanent Loans are a popular option, covering both the land and build in a single loan with one closing process. Speaking with a lender early helps you understand your options and secure pre-approval before detailed design work begins.

Phase 4: Construction

Breaking Ground to Foundation

Once permits are approved, construction officially begins. The first phase involves site preparation, excavation, and laying the foundation—typically the first 1.5 months of the build. In Austin, this stage may take longer than typical due to soil conditions, tree preservation requirements, or sloped land that requires erosion controls.

Framing, Systems & Exteriors

After the foundation is set, the skeleton of your home is framed. Rough framing, sheathing, and roofing typically take 2–3 months, followed by rough-in plumbing, electrical, and HVAC installations. Exterior finishes—including siding, roofing, windows, and doors—are installed during this phase as well.

Interior Finishes & Final Installation

Insulation, drywall, painting, trim, flooring, cabinets, and fixture installation comprise the final stages of construction. This phase allows your personal style to truly shine as your selections become reality.

Flexibility & Change Orders

Even with detailed planning, you might decide to make adjustments once construction is underway. If changes become necessary after construction begins, they’re handled through a formal change order, which clearly outlines the new scope of work and any associated costs or schedule adjustments.

The Design-Build Advantage: Why It Matters for Your Austin Custom Home

Choosing a design-build approach offers distinct benefits for your custom home project:

Single Point of Contact: One team, one contract, and one person coordinating your entire project from concept to completion.
Integrated Collaboration: Your architect and builder work together from day one, preventing costly design decisions that don’t account for construction reality.
Faster Timelines: The design-build model streamlines the entire journey, minimizing the delays and miscommunications that often plague traditional construction projects.
Better Budget Control: Because design and construction teams collaborate during the planning phase, your home is designed with realistic cost understanding, preventing expensive surprises.
Seamless Communication: Clear protocols and regular updates keep you informed and involved throughout the process, transforming a potentially stressful journey into an exciting partnership.

FAQ: Your Custom Home Building Questions Answered

1. How long does it take to build a custom home in Austin?

A typical custom home build in Austin takes approximately 12–18 months from the initial design meeting to final move-in. However, pre-construction planning—including land selection, design, and permits—can add several months. Overall, many homeowners should count on approximately two years from initial planning through completion. Timeline variables include design complexity, permit approval speed, site conditions, and how quickly you make material selections.

2. What are the key differences between design-build and traditional construction?

In traditional construction, you hire an architect separately to create full plans, then shop those plans to different general contractors for bids. The design-build approach, by contrast, brings your architect and contractor together from the start under one contract, providing a single point of contact and eliminating finger-pointing if issues arise. Design-build typically results in faster timelines, better budget control, and more integrated decision-making.

3. What permits do I need for a custom home in Austin?

Custom homes in Austin require a building permit, along with specialized trade permits for electrical, mechanical, and plumbing work. Depending on your specific site, you may also need tree permits (if regulated trees are impacted), water permits (for septic or utility work), or site plan permits. Your design-build team manages the permit application and coordination with the City of Austin’s Development Services Department.

4. Can I make design changes during construction?

Yes, changes are possible, but timing matters. While design-build teams work hard to finalize all decisions before construction begins, adjustments are sometimes necessary and are handled through formal change orders that outline new scope, costs, and schedule impacts. Making changes early in the process is less disruptive than changes made during later construction phases.

5. What should I expect during the construction phase?

Construction unfolds in stages: site preparation and foundation (1.5 months), framing and rough systems (2–3 months), exterior finishes (1–2 months), and interior finishes including paint, flooring, and fixtures (4+ months). Your design-build team will keep you informed of progress through regular updates and site visits, and you’ll have opportunities to make decisions on remaining selections as the home takes shape.
