Custom Homes Built for Simi Valley's Valley and Hills
Ground-Up Construction & Rebuilds · Licensed & Insured · Lic. #1027281 · Since 1994
A city built almost entirely from repeated tract plans leaves an opening: land and owners ready for a house designed for this specific valley instead of stamped across it. Master Construction has built homes in Ventura County since 1994 as a licensed general contractor (Lic. #1027281), taking projects from raw lot or teardown through design, engineering, permits and construction with one accountable team. The county practice is on our residential construction page; how we work locally is here and on the Simi Valley page.
Designing a House for the Hottest City We Serve
In Simi Valley the climate brief writes itself: summers past 100 degrees, strong sun, dry winds, cool winter nights. A custom home here earns its keep through orientation and envelope decisions no tract plan ever made. Deep overhangs and porches shade the south and west glass. Windows are placed for cross-ventilation on the evenings when the valley finally cools. Insulation and air sealing get specified past code minimums because every dollar in the envelope comes back through the HVAC system for the life of the house.
The roof works too: light finishes, radiant barriers, and structural provision for the solar array that state code requires on new homes and that this valley's sun rewards better than almost anywhere in the county.
None of this shows in a rendering. All of it shows in August, in the utility bill and in rooms that stay comfortable at 4 p.m. without the compressor running flat out. Designing for the climate is not a style; it is the difference between a custom home and a big tract home.
Hillside Lots Are a Different Project
The valley floor builds simply: flat lots, straightforward foundations, predictable budgets. The lots people fall in love with, up against the Santa Susana slopes with views over the city, build differently. Grading and retaining come first, drainage must be engineered so winter storm flows move around the house instead of through the crawl space, and properties on the wildland edge carry fire-conscious requirements for materials and defensible space that a flat-lot budget never sees.
We tell owners the honest sequence: the lot gets evaluated before it gets purchased, whenever we are brought in early enough. Soils, slope, access for equipment and utility runs can swing a hillside budget dramatically, and knowing that before escrow closes is worth more than any discount after.
Once the ground is understood, hillside houses reward the effort: stepped foundations that follow the slope, main rooms aimed at the view, outdoor living on the shaded side. It is the most demanding building in Simi Valley and, done right, the most satisfying.
One Team From Plan Check to Keys
Custom building fails at the seams between designer, engineer and builder, so we remove the seams. Our design-build process prices the house while it is being drawn, which means the plans that go to the city are plans you can afford to build. Structural engineering, energy compliance and the submittal package move as one effort.
Plan review runs through the City of Simi Valley, where submittals get a counter completeness review before plan check fees are even invoiced; a complete, coordinated package the first time is worth weeks. We manage the corrections cycle and every inspection from foundation to final, and the schedule we give you includes the review, not just the construction.
Some clients on this page are not homeowners: investors and project managers building on spec or managing a family project from out of the area. They get the professional version of our process, milestone reporting, clean draw documentation, decisions batched for efficiency, and a builder who treats their absence as a reason for more documentation, not less.

FAQ
Simi Valley Custom Homes - FAQ
What does a custom home cost to build in Simi Valley?
It depends on the lot as much as the house: a flat valley parcel and a Santa Susana hillside can differ by six figures before framing starts, driven by grading, retaining and drainage. We give ranges after seeing the lot and firm pricing as the design develops, which is the honest version of this answer.
Should the lot be evaluated before we buy it?
Yes, and it is the cheapest advice on this page. Slope, soils, access and utilities set the real budget for a hillside parcel, and a walkthrough with a builder before escrow closes has saved our clients from expensive surprises more than once. We do this early evaluation as a matter of course.
How long does the whole process take?
Roughly a year to two years all-in: several months of design and engineering, the city's review cycle, then twelve months or more of construction depending on size and site. Hillside grading extends it. We map the timeline at the start and report against it monthly, so the answer is never a mystery mid-project.
What does building near the wildland edge require?
Fire-conscious choices: ember-resistant vents, noncombustible cladding and roofing, tempered glazing considerations, and defensible space planning around the structure. Requirements depend on the parcel's designation, which we confirm with the city early so the design carries them from the first drawing rather than absorbing them in plan check.
Does a new Simi Valley home need solar?
California's energy code requires solar on new homes, and this valley's sun makes the requirement a genuine asset rather than a tax. We design the roof orientation, conduit and panel capacity for it from the start, with battery backup pre-wired if you want the option later without opening walls.
Can you rebuild on a lot with an existing house?
Yes. Teardown-rebuild is often the practical route to a custom home in an established neighborhood, and we handle the demolition permits, utility disconnects and the rebuild as one project. Whether remodeling the existing house would serve you better is a question we answer honestly at the first meeting.
Do you build for investors and project managers?
Yes. Spec builds and remotely managed projects get milestone schedules, draw-ready documentation, photo reporting and batched decision points, with one accountable contact. We run the project as if the owner will audit everything, because good investors do.
