What Conversion Requires

Converting a garage involves more than just painting walls:

Foundation

Most garages have a concrete slab—may need leveling or additional footings

Insulation & Drywall

Garage walls typically have no insulation—essential for climate control

HVAC Extension

May need to extend ductwork or add mini-split AC/heat

Electrical Upgrades

Outlets, lighting, and possibly panel upgrades

Flooring

Replace concrete with hardwood, tile, or epoxy coating

Garage Door Removal

Fill in the opening with a proper wall and windows

ADU Considerations for Houston

Want to create a rental unit or mother-in-law suite?

  • Montgomery County: ADUs allowed with permits on most residential lots
  • HOA restrictions: Check your subdivision rules—many prohibit rental units
  • Utility separation: May need separate meters for electric, water, gas
  • Parking replacement: Some areas require replacement parking if garage is converted
  • Septic/sewer: Confirm capacity if adding a full bathroom

Keep Parking? Consider a Garage Addition

If you need both parking AND living space, building a new garage with living space above (garage apartment) might make more sense than converting your existing garage. We can help you weigh the options.
