Home Addition in Pacifica

Why Expand Your Pacifica Home

In Pacifica’s competitive housing market, expanding your current home often makes more financial sense than buying larger. A well-planned addition adds both space and property value. Coastal construction requires salt-air-resistant materials, wind-rated designs, and compliance with the Local Coastal Program.

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 Pacifica

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 Pacifica.

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 Pacifica Additions

Home additions in Pacifica require careful structural planning to ensure the new space integrates safely with the existing structure. Custom Home’s engineering team handles foundation evaluation, load-bearing wall modifications, and structural design. Whether you are adding a second story or expanding your footprint, structural engineering is included in our Phase 1 design process.

Pacifica Home Addition Permits

Pacifica’s Planning and Building Division processes residential building permits with typical plan review taking 6-10 weeks for custom homes. Hillside projects may require a geotechnical report and grading plan review. Properties in certain zones are subject to the city’s Local Coastal Program requirements. Custom Home prepares complete permit-ready plans that address all of Pacifica’s building and planning requirements.

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