Introduction to Home Additions in Del Sur

Del Sur, a master-planned luxury community in San Diego, is known for its beautiful homes, parks, and trails. However, as families grow and needs change, many homeowners in Del Sur find themselves needing more space. A home addition can be a great way to add value to your property and create the space you need.

Before starting a home addition project, it's essential to understand the process and what to expect. In our experience, a typical home addition project in Del Sur can take anywhere from 3-12 months to complete, depending on the scope of work. The first step is to design the addition, which involves working with an architect or designer to create a plan that meets your needs and complies with local building codes. Once the design is complete, we'll obtain the necessary permits from the San Diego County building department, which can take several weeks to several months.

Room Addition vs. Second Story Addition

When it comes to adding space to your home, you have two main options: a room addition or a second story addition. A room addition involves adding a new room to your existing home, such as a bedroom, bathroom, or family room. This type of addition can be less expensive than a second story addition, with costs ranging from $80,000 to $200,000. A second story addition, on the other hand, involves adding an entire new level to your home, which can be more expensive, with costs ranging from $250,000 to $500,000 or more.(See also: cost & budget in Solana Beach)
