🏠Why Adding Square Footage is a Smart Investment
In San Diego’s competitive real estate market, square footage matters. Adding space isn’t just about comfort—it’s a strategic way to improve your home’s layout, increase functionality, and raise your property’s resale value.
Whether you're planning for a growing family, a dedicated home office, or an in-law suite, a home addition lets you stay in the neighborhood you love while increasing your home's potential.
