Home Additions

Add square footage without leaving the neighborhood. Room additions, second-story builds, primary-suite expansions, and bump-outs, handled from permit through final inspection.

Why add

Why people add instead of move.

In most Los Angeles neighborhoods, the cost of moving (closing fees, prop-tax reassessment under Prop 19, the spread between buying and selling) is often higher than adding the square footage you need to the home you already own.

Additions also let you keep what you already like about your home and your block: schools, neighbors, the lot, the trees. The goal of a well-designed addition is to make the finished home feel like it was always one piece, not a tacked-on extension.

Process

From sketch to final inspection.

Walkthrough & budget range. We visit the property, discuss what you want to add, and provide a budget range and rough timeline before any drawings are commissioned.

Plans & engineering. We coordinate with an architect or designer (yours or ours) and the required structural engineer. Plans are submitted to Building & Safety.

Permit & construction. Once the permit is pulled, our team handles foundation, framing, mechanical rough-in, drywall, finish work, and all required inspections.

Final walkthrough. We walk the project with you, complete the punch list, and pass the final inspection.

Common questions

Addition FAQs.

A first-floor addition typically runs four to seven months from permit pull to final inspection. Second-story additions and large primary-suite builds usually take six to nine months. Plan and permit time before construction varies by jurisdiction and can add three to six months.
For most additions, yes. We can work with an architect you have already retained, refer you to architects we have worked with for years, or in some smaller cases prepare plans through a licensed designer. A structural engineer is required for any framing or load-bearing work.
For first-floor additions that do not impact the main living areas, often yes. For second-story builds or projects that affect plumbing, electrical, or roofing, we usually recommend temporary relocation for at least part of the build. We will be honest about this during the walkthrough.
Addition cost depends on the size, the finish level, structural complexity, and whether it is a ground-floor build or a second story (second stories cost more because of the added structural and access work). After the walkthrough we provide a written estimate broken down by line item.
