Even though the foundation, roof and walls are already in place, hiring a contractor is a smart choice, even if you have amateur experience with some remodeling projects, because you may need to install extra plumbing and electrical work. In addition, you may run into unforeseen structural issues or other issues that could risk safety or end up decreasing the property value. Planning ahead will save you time and money in the long run. However, before you go with a contractor, look at his or her work; don't rely on word of mouth. In addition, you and the contractor should use durable materials that will last for years.
You may be unaware that, when enclosing a garage, you must adhere to state and local zoning regulations. Because different states, cities and towns have adopted varying regulations, contacting your local government or county will provide you with specific instructions and potential permits. One common requirement that many areas have adopted includes requiring homeowners to provide "alternative on-site parking." Likewise, many areas require homeowners to ensure their new living space does not cause privacy issues with neighbors and the exterior of the enclosed garage complies with neighborhood appearance requirements.
When choosing whether or not to enclose your garage, perhaps one of the most important elements to consider is the amount of moisture and the leveling of the garage. Sometimes garage slabs do not have vapor barriers, meaning moisture could easily climb through the slab and make floors damp, which could lead to musty smells or even mold. You have two fixes to this problem. One fix is to hire a professional to apply a vapor barrier over the slab. Another option is to replace the slab and add a vapor barrier in the process. Another common issue with garages is that garage floors are not always level. While this may not matter to you, it could be an issue to potential buyers in the future, so releveling the floor may be worthwhile.
