FAQ

A home addition is a smart way to transform your living environment without leaving your neighborhood while giving you the freedom to personalize your space, add functionality, and increase the value of your property. A well-designed and built addition can match the style of your existing home and enhance your family’s daily life. Whether you're planning for future growth or simply want more room to enjoy, a well-executed addition blends comfort and modern upgrades into a more usable, convenient living space.

San Luis Obispo home addition construction can unfold in stages, reflecting the complexity involved in each step of the process. An experienced contractor knows how to coordinate it all with local authorities, including planning, permitting, and construction, based on a specific timeline. We take a proactive approach to scheduling at Harrod Built, ensuring the entire process progresses smoothly while also ensuring we deliver high-quality construction and well-crafted details.

You will likely need a permit for your home addition in San Luis Obispo County. Custom ADUs (accessory dwelling units) also almost always need a special permit. If you plan to build a detached unit, convert your garage, or add space to your existing home, specific County rules must be followed. Local laws about zoning, size, setbacks, and utility connections need approval during the permitting process. Don’t think about skipping this step, or work may have to be redone, or you could be fined. Our building professionals at Harrod Built are experts at navigating San Luis Obispo County’s ADU regulations when you need this service.

From guest suites and home offices to sunrooms and second-story expansions, Harrod Built can create home additions that integrate perfectly with your existing home. We also build energy-efficient ADUs that can generate income, and we handle permitting to follow regulations about sizes and setbacks. If you need an upgraded master suite, want kitchen remodeling, or a multi-purpose family room added onto your home, we offer home remodeling services that will ensure your addition harmonizes with your home’s current aesthetic.
