Custom Home Building for Santa Clarita Homeowners
We handle custom home building in Santa Clarita for owners who have a lot, or a house they plan to replace, and want one team responsible from the first site visit to the final inspection. As a licensed California general contractor, Simply Construction coordinates the architect, engineers, city reviewers and trades under a single contract.
In this valley the lot usually decides more than the floor plan does. A Sand Canyon parcel can span acres of oaks and slope, while an infill site near Old Town Newhall has neighbors close on both sides. We walk the site, pull the zoning and fire mapping, and give you an honest read on what can be built before you pay for full drawings.
Local Knowledge
Custom Home Sites in Santa Clarita: Oaks, Slopes and Fire Zones
The best custom home sites in Santa Clarita are often the least simple. Sand Canyon's roughly 1,000 homes sit on lots from a half acre to 20 acres, with no sidewalks or street lights and trails used by riders. Placerita Canyon has its own special standards district meant to protect its secluded, rural equestrian character, and its homes range from the 1920s to recent builds. A new house in either place has to fit that character as well as the code.
Terrain adds another layer. The city's hillside development rules apply where the average cross slope is 10 percent or more, steer building toward areas of 25 percent slope or less, and bring grading of more than 100 cubic yards on those slopes under hillside standards. Ridgelines inside the preservation overlay cannot be altered without a separate ridgeline alteration permit.
Then come oaks and fire. Work inside an oak's protected zone needs a city oak tree permit, and a new home inside a fire hazard severity zone needs Los Angeles County Fire to approve a fuel modification plan before the building permit is issued. We fold all of this into the site plan from the first sketch.

Planning Considerations
Planning a Custom Home in This Valley
Designing for Summer Heat
Summer afternoons in the Santa Clarita Valley often exceed 100 degrees, and the valley forms a corridor that funnels Santa Ana winds. That affects orientation, glazing and overhangs as much as the mechanical plan. We push for deep shading on west-facing walls, a well-insulated roof assembly, and heating and cooling sized from a real load calculation instead of a rule of thumb. Those choices also ease Title 24 compliance.
Seismic Engineering Comes First
The 1994 Northridge earthquake collapsed two connector structures at the Interstate 5 and State Route 14 interchange in the Newhall Pass, cutting the valley off from much of Los Angeles for nearly six months. Every custom home we build follows a stamped structural design with the hold-downs, shear walls and foundation details it calls for, and we do not substitute hardware in the field without the engineer's approval.
City or County Jurisdiction
Not every Santa Clarita mailing address is inside the city. Unincorporated communities such as Stevenson Ranch and Castaic are permitted by Los Angeles County Public Works through its Santa Clarita Valley office, under county zoning rather than the city's code. We confirm jurisdiction on day one, because it changes the setbacks, the fees and the reviewers for the whole project.
Why Choose Us
Why Santa Clarita Homeowners Choose Simply Construction
Licensed, Bonded and Easy to Verify
Simply Construction inc. is a licensed California general contractor, CSLB [CSLB LICENSE # PLACEHOLDER]. State law requires a license for any job of $1,000 or more in labor and materials, and anyone can check a contractor's license, bond and workers' compensation status on the CSLB website in about a minute. We encourage every Santa Clarita homeowner to do exactly that before signing with anyone, including us.
Straight Answers on Feasibility
Some lots cannot fit the project an owner has in mind. We check zoning, setbacks, height limits, easements, slope and utility capacity early, and we tell you plainly what is achievable before you spend money on full drawings. When state law opens a path that the local code seems to block, as ADU and SB 9 rules often do, we explain how it applies to your property.
Written, Line-Item Estimates
Before you commit, you receive a written estimate that breaks the project into its real parts: design and engineering, permit and utility fees, foundation, framing, systems, finishes and site work. Allowances are named and priced, so you can see where your selections move the budget. If the scope changes, the numbers change on paper first, never as a surprise on the final invoice.

FAQ
Custom Home Building in Santa Clarita: Common Questions
What approvals does a Santa Clarita custom home need before construction?
It depends mostly on the lot. A flat infill site needs Planning clearance, plan check and the usual agency sign-offs. A hillside or oak-covered site can add hillside review, an oak tree permit and a fuel modification plan, each with its own reviewer. We map every approval your lot needs at the start and build the schedule from that list rather than a guess.
Can I build a custom home on a horse property in Sand Canyon or Placerita Canyon?
Yes, and many owners do. The work is in fitting the house to the land: keeping barns, arenas and trails usable, respecting Placerita Canyon's special standards district, staying outside oak protected zones and meeting fire access and fuel modification requirements. We plan the whole site so the house, garage and animal facilities work together.
Do new custom homes need solar?
In most cases, yes. Solar PV has been part of the Title 24 energy code for most new single-family homes since January 1, 2020, and any permit application submitted on or after January 1, 2026 falls under the 2025 Energy Code. We coordinate the panel layout with the roof design early so the array suits the architecture.
