Why home additions

More space without leaving the life you’ve built

Moving to a larger home means uprooting everything: your commute, your kids’ schools, your neighbors who’ve become friends. A thoughtfully designed addition delivers the square footage you need while keeping everything else exactly where it belongs.

Whether you’re planning an in-law suite for aging parents, a second-story addition for growing teenagers, or a sunroom to capture Michigan’s beautiful seasons, Wright’s Renovations brings the expertise to make your vision feel inevitable rather than added-on. Our design-build approach means one team handles everything from architectural drawings to final walkthrough, eliminating the coordination headaches that plague traditional construction projects.

Some additions do not fit a single category. A four-season room keeps the view without the seasonal shutdown. An attached garage addition solves storage and entry in one build, and a great room addition opens up the middle of the house. Older homes set their own rules, so a colonial home addition follows a different path than a ranch, and luxury addition work carries its own level of detail.

Michigan building expertise

Built for Michigan’s unique conditions

Out-of-state contractors and inexperienced builders miss critical details that Michigan’s climate demands. We’ve spent years mastering the technical requirements that protect your addition investment for decades.

42-inch frost line compliance

Michigan footings must extend 42 inches below grade, deeper than many neighboring states. Every foundation we pour meets this critical requirement to prevent costly frost heave damage.

Climate Zone 5-6 insulation

We exceed minimum R-values with R-49 ceiling, R-20 wall, and R-30 floor insulation, ensuring your addition stays comfortable through sub-zero winters and humid summers.

Multi-county permit expertise

From Ann Arbor’s historic district requirements to Northville’s architectural review board, we navigate the varying regulations across Washtenaw, Wayne, Oakland, Macomb, Livingston, and Monroe counties.

Weather-resistant materials

We select siding, roofing, and fenestration specifically rated for Michigan’s freeze-thaw cycles, ensuring your addition weathers decades of lake-effect snow and spring storms.

Every project is unique. Schedule a consultation to discuss your specific addition plans and get personalized answers.

How much does a home addition cost in Michigan?

Home addition costs in Southeast Michigan typically range from $150 to $500 per square foot, depending on the type of addition and finish level. A basic room addition starts around $80,000, while a full in-law suite with kitchen and bathroom starts at $150,000. Second-story additions require structural engineering and typically cost $200-500 per square foot. We provide detailed, fixed-price proposals after our consultation process.

Do I need a permit for a home addition in Michigan?

Yes, home additions in Michigan require building permits in virtually all cases. Permit requirements and fees vary by municipality—Ann Arbor permits cost more and take longer than smaller townships like Dexter or Saline. Our team handles all permit applications, inspections, and code compliance as part of our design-build service. We maintain relationships with building departments across all six counties we serve.

How long does a home addition take to complete?

Timeline depends on project scope. A mudroom addition might take 6-8 weeks, while a full second-story addition could require 4-6 months. Our 42-day average cycle time beats industry norms because thorough pre-project planning eliminates delays. Your project portal shows the complete timeline with milestones before we start construction.

Can I stay in my home during construction?

Most of our clients remain in their homes throughout construction. We create sealed work zones with HEPA air filtration, establish separate entrances for crew members, and schedule noisy work around your daily routines. For major projects like whole-home renovations, we discuss alternative arrangements during our planning phase.

What’s the difference between design-build and traditional construction?

Traditional construction requires you to hire an architect, get plans, then bid them out to contractors—coordinating between multiple parties. Design-build means one company handles everything: design, permits, construction, and finish work. You get a single point of contact, single contract, and single source of accountability. This eliminates finger-pointing between designers and builders while typically saving 15-20% compared to the traditional approach.

Will my addition match my existing home?

Seamless integration is our specialty. We match rooflines, siding profiles, window styles, and architectural details so your addition looks original to the home. For historic properties in places like Ann Arbor’s Old West Side, we work with period-appropriate materials and methods while meeting modern energy codes. The result: guests won’t be able to tell where the original house ends.

Are you licensed and insured?

Absolutely. Wright’s Renovations is a fully licensed Michigan residential building contractor and carries comprehensive general liability insurance and workers’ compensation coverage. All crew members are background-checked, uniformed, and carry photo ID. We’re happy to provide proof of insurance and licensing to any prospective client.
