Home Addition in Old Palo Alto

Why Expand Your Old Palo Alto Home

Old Palo Alto is among the most desirable neighborhoods in Silicon Valley, and homeowners here rarely want to leave. Expanding your current home lets you gain the space your family needs while staying in the neighborhood you chose. Large lots in Old Palo Alto often provide room for significant ground-floor additions without sacrificing yard space.

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 Old Palo Alto

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. In Old Palo Alto, second-story designs should be sensitive to the neighborhood’s established scale and character.

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 Old Palo Alto’s established residential areas.

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 Old Palo Alto Additions

Old Palo Alto 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.

Old Palo Alto Home Addition Permits

Old Palo Alto falls under the City of Palo Alto’s Planning and Development Services department. The city requires Individual Review for significant additions, evaluating compatibility with neighborhood context. Standard plan review takes 6-10 weeks.

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