Convenience is the biggest plus when it comes to deciding on an attached garage. Being able to enter and exit the home from the garage is especially attractive in climates with heavy precipitation or extreme temperatures. Without a covered pathway, which would add to the cost, going to a detached garage in inclement weather will not be a fun experience. Even in temperate climates, carrying heavy packages from the car to the house is easier with an attached garage.
Whether an attached or detached garage adds to or detracts from your home’s value depends partly on two factors: curb appeal and consistency with other homes. An attached garage that faces the front can detract from the look of the home, especially if the home is small. A detached garage in a neighborhood dominated by homes with attached garages can lower the home’s value.
Of course, the climate plays a significant role as well. In a very hot, cold, or wet climate, not having a garage for the home, especially an attached one, can be a deal breaker. However, when all is considered, real estate professionals estimate that a two-car garage, attached or detached, will add approximately $45,000 to the value of a home, and a one-car garage will add about $15,000 to $20,000. Factors that increase that value are an electric door opener, an opening that does not face the street, and extra space for storage.
