What’s Happening

When homeowners search “ADU vs garage conversion,” they’re usually standing in front of an underused garage and asking one specific question: is it cheaper and faster to convert what’s already there, or does building something new make more financial sense? Both paths create legal living space on your property, but they work differently, cost differently, and not every lot qualifies for both.

A garage conversion turns your existing structure into living quarters. You keep the foundation, the walls, the roof – and you trade parking space for livable square footage. A detached ADU (accessory dwelling unit) goes up as a separate structure on your lot, which means more flexibility on size and placement, but also a longer construction timeline and a different permit process. The right answer depends on your garage’s condition, your lot size, local zoning, and what you actually need the space to do. That last part matters more than most people expect.

The name Lodgewick comes from “lodge” – a small house on a larger property. That’s exactly what an ADU is, whether you build it from scratch or carve it out of a garage that’s mostly storing things you forgot you owned.

Why It Happens

Your Garage Already Has the Shell – But It May Not Have the Bones

Most attached garages were built to hold cars, not people. The slab is usually poured without insulation underneath it, the ceiling height is often marginal, and the framing may not meet current residential occupancy codes. You can see the ceiling height issue immediately – stand inside and look up. If it’s under 7 feet 6 inches in most jurisdictions, you’re looking at a structural lift or a different plan. That doesn’t disqualify the project, but it changes the budget significantly.

Zoning Rules Treat ADUs and Garage Conversions Differently

Many places that allow ADUs have specific rules about detached vs. attached units, setbacks from property lines, and owner-occupancy requirements. A garage conversion that’s attached to your main house might be classified as a junior ADU (sometimes called a JADU) rather than a full ADU, which affects what you can charge for rent and who can live there. Before you commit to either path, the permit picture needs to be clear. Your local Lodgewick ADU Builders team pulls permits and handles the jurisdiction research as part of the build process – not as an afterthought.

Budget Expectations Don’t Match the Actual Scope

People often assume a garage conversion costs a fraction of a new build because the shell is already there. Sometimes that’s true. Sometimes the garage needs a new roof, upgraded electrical service, proper insulation, and a bathroom rough-in that requires cutting concrete – and the cost difference narrows considerably. Neither option is automatically cheaper. The only way to know is a written estimate that breaks out every line item for your specific structure and lot.

The Goal of the Space Pulls You in Different Directions

A garage conversion works well for a home office, a guest suite, or a space for a family member who wants proximity but not shared walls. A detached ADU gives a tenant genuine independence – a separate address, a separate entrance that doesn’t share a wall with your kitchen, and in many cases, a better rental income potential. If your goal is long-term rental revenue, the detached ADU often pencils out better over five to ten years. If your goal is a flexible bonus room, the conversion is faster and simpler.

What to Do Right Now

• Photograph the existing garage thoroughly. Interior walls, ceiling height (use a tape measure and note it), the electrical panel inside or near the garage, the floor condition, and any signs of water intrusion at the base of the walls. These photos matter during the estimate conversation.
• Check your property survey or plot plan. If you have one from when you bought the house, pull it out. It shows setbacks, easements, and total lot square footage – all of which factor into what your zoning allows.
• Write down what you need the space to do. Guest suite for parents? Long-term rental unit? Home office? Short-term rental? Each use has different permit implications and building requirements. Being clear on this before the first call saves time.
• Don’t start demo or framing work yet. It’s tempting to rip out the drywall or pull up the garage door hardware before anyone arrives. Don’t. Work done before permits are pulled can create serious problems with inspections – and in some cases has to be undone.
• Call (254) 602-5618 and describe what you’re seeing. A live person answers every call. Tell them about the garage, your lot, and what you’re trying to accomplish. That conversation costs nothing and gets you pointed in the right direction before any money changes hands.

How We Fix It

When a Lodgewick ADU Builders technician arrives, the first thing they do is walk the lot and the existing structure together with you. Not a quick glance – an actual look at the slab, the ceiling, the electrical, the setbacks, and the access points. They’re figuring out which path is physically possible on your lot, which path matches your budget range, and which path gets you the space you actually described.

From there, you get a written price before anything starts. That’s not a ballpark figure – it’s a line-item quote that covers the work from permit application through final inspection. No verbal agreements, no price that changes when the crew shows up. That’s what “Say the price before the work” means under The Kingswell Way.

Depending on what makes sense for your lot, the project falls under our Garage Conversion service or our ADU Builders service – or sometimes a combination if you’re adding a detached unit and repurposing the garage simultaneously. The timeline, the permit path, and the material choices (we work with Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie products) all get laid out before work begins. And every project is covered by our 365-Day Done Right Promise: if the work isn’t right, we come back and make it right. That commitment is in writing.
