General contractor serving Castaic
Sierra Development serves Castaic and nearby communities with residential, outdoor, sitework, and commercial construction scopes. For a larger lot, hillside project, renovation, or new living space, the property and access conditions should be reviewed alongside the design. Manuel Carrillo is the owner and the point of contact for the construction discussion.
Let access and the site guide the scope
Describe the route from the street to the proposed work area, any changes in elevation, and where equipment or materials can be staged. A backyard wall, new structure, or pool can involve excavation, hauling, utility routes, and protection of existing improvements. Include photographs of the approach as well as the finished area you want to change.
For properties with more extensive outdoor space, distinguish the specific construction area from the whole parcel. Identify existing structures, drainage concerns, and any information already available about the ground. Do not assume a larger lot eliminates design, access, or approval constraints.
Check the authority for the property
Los Angeles County Building and Safety provides services for unincorporated communities and certain contract cities. Its permit guidance directs applicants to the district serving the project address. Confirm that route for your Castaic-area property instead of assuming Santa Clarita city procedures apply.
If private systems, grading, or other agency reviews are relevant, identify them before the construction scope is finalized. Send plans and existing records when available. We do not infer an approval or engineering solution from a community name.
Discuss the complete Castaic build
Common inquiry scopes include home additions, ADUs, whole-home remodeling, retaining walls, concrete, drainage, patios, and pools. Let Manuel know which are connected and which may be separate phases. We also welcome inquiries from Val Verde and Hasley Canyon; these are service communities, not claims of local offices or completed projects. Use the inquiry form with your location, plans, and construction goals.
