Home Addition in Burlingame

Why Expand Your Burlingame Home

For Burlingame homeowners who love their neighborhood but need more space, a home addition is often more practical than buying a larger home. You keep your location, your neighbors, and your established landscaping. Established neighborhoods and proximity to both San Francisco and Silicon Valley create consistent demand for quality construction.

Custom Home designs and builds home additions with the same two-phase process we use for custom homes. You see the complete addition in 3D and receive itemized pricing before construction begins.

Types of Home Additions We Build in Burlingame

Second-Story Additions

Double your living space by building up rather than out. Second-story additions are ideal when lot coverage limits prevent ground-floor expansion. Custom Home’s structural engineers evaluate your existing foundation to determine what reinforcement is needed.

Ground-Floor Room Additions

Extend your home’s footprint with new bedrooms, family rooms, or home offices. Ground-floor additions integrate with your existing layout and maintain single-level living, which is especially valued in Burlingame.

Bump-Outs and Extensions

Smaller expansions that make a significant difference: extend your kitchen, enlarge a bathroom, or add a sunroom. Bump-outs typically cost less and complete faster than full additions.

Structural Considerations for Burlingame Additions

Burlingame is located in a seismically active region, which means home additions must meet current seismic codes. Custom Home’s engineering team handles foundation evaluation, load-bearing wall modifications, and seismic design for every addition project. Whether you are adding a second story or expanding your footprint, structural engineering is included in our Phase 1 design process.

Burlingame Home Addition Permits

Burlingame’s Community Development Building Division handles residential permits. Plan review for custom homes typically takes 4-8 weeks. The city requires design review for new construction and major additions, assessing compatibility with neighborhood character. Online permit applications are available for smaller projects, and the city offers pre-application meetings to discuss scope and requirements before formal submission.

Custom Home manages the entire addition permitting process, including structural engineering review, plan submittal, and inspection coordination. Our experience with Burlingame’s requirements helps keep the approval process on track.
