Home Additions for Santa Clarita homes

Santa Clarita lots range from flat tract lots in Saugus to hillside lots in Canyon Country and Valencia. Many neighborhoods have associations that review additions. Homes in the canyons and on hillsides are often in fire hazard zones, where Chapter 7A applies.

We check those constraints first, pour the foundation and build the addition to match. Permits come from the Santa Clarita Permit Center or LA County for unincorporated areas.

This page covers Santa Clarita specifically. For materials, process and costs in general, see our home additions page, and for permits and neighborhoods, our Santa Clarita service area page.

Planning an addition in Santa Clarita

Santa Clarita lots vary from flat tracts to hillside canyon lots. Hillside additions need engineered foundations, and canyon homes in fire hazard zones follow Chapter 7A. Associations review most additions.

We check zoning, association rules and fire zone status first, then design and build the addition to match the house.

Cooling the new space is part of the plan, given inland summers.

On flat Valencia and Saugus lots, rear additions for family rooms and primary suites are common. Associations review the exterior design. On canyon lots, engineered foundations and fire-resistant materials add cost but are required.

We pour the foundation, frame the addition and match the house. Cooling the new room is part of the plan, either by extending the existing system or adding a ductless unit.

    "All work was constructed via architect design. We eliminated a bay window and slider and extended an exterior wall making room for a stand alone tub and facilities relocation to accommodate more closet space. All new tile was installed throughout."
