Review slab, ceiling, egress, insulation, utilities, parking and existing conditions.

The honest answer

A garage slab and shell were not necessarily built as living space. Moisture, floor elevation, insulation, ceiling height, and emergency exit requirements need proof.

If you are worried about investing in plans and permits only to learn that the site, structure, utilities, or budget cannot support the project, that concern is reasonable. Remodeling is expensive, disruptive, and hard to judge once important work is covered. You deserve clear proof before you approve the next step.

What you are really deciding

Review slab, ceiling, egress, insulation, utilities, parking and existing conditions. That means you need to settle more than appearance. The decision must work with the room, adjoining materials, manufacturer requirements, and the contractor's installation plan.

For this topic, the details that deserve a written answer are slab, ceiling, egress, insulation, utilities, and parking. If one of those details is still described as “we will figure it out later,” ask what work depends on it and who pays if the late answer forces rework.

Plain-English technical note

Egress means a safe, code-compliant way to get out during an emergency, often through a properly sized door or window.

Where budgets and schedules go wrong

New square footage carries costs that are easy to overlook: design, engineering, utility work, excavation, structure, weather protection, and connections to the existing home.

The decision to settle before work continues

Review slab, ceiling, egress, insulation, utilities, parking and existing conditions. Ask which part must be confirmed on site and which part can be trusted to a catalog or plan. That distinction matters because houses are rarely as square, level, or predictable as a showroom display.

For garage conversion planning, request one named person who is responsible for coordination. If the answer is “everyone,” the practical result is often that no one checks the handoff between trades.
