Your Santa Clarita Builder for Homes, ADUs and Additions
Simply Construction works as a general contractor in Santa Clarita on the large residential projects that need the most coordination: ground-up custom homes, detached and attached ADUs, garage conversions, room additions, second stories and new garages. We are a licensed California general contractor, and we run each job from early feasibility through plans, permits, construction and final inspection under one contract.
Santa Clarita rewards that kind of planning. A project in a Valencia village may need HOA architectural approval alongside the city's review, while a lot in Placerita Canyon or Sand Canyon can bring an oak tree permit, hillside standards and a fire department fuel modification review. We sort those layers out first, so the design you approve is one that can be permitted and built.
What We Build Here
Our Services in Santa Clarita
Every project below is planned, permitted and built by one licensed team. Choose a service to see how it works in Santa Clarita.
Custom Home Building in Santa Clarita
Most custom homes here rise on the valley's larger parcels, from equestrian lots in Sand Canyon and Placerita Canyon to older sites around Newhall. Those lots often carry oak trees, slopes and fire zone mapping all at once. We plan the house around oak protected zones, the city's hillside standards and Los Angeles County Fire's fuel modification review before the architect finalizes the footprint.
ADU Construction in Santa Clarita
Santa Clarita's ADU handout allows a detached unit of up to 1,200 square feet, sets no parking requirement for ADUs or junior ADUs, and lets the unit be rented but not sold separately. We handle the Planning clearance that comes before building plan review, the HOA submittal in Valencia villages, and the extra access test the city applies in high fire hazard areas.
Garage Conversions in Santa Clarita
The attached two-car garages on Saugus and Canyon Country tract homes are some of the easiest square footage to reclaim in the valley. Converting one into an ADU needs no replacement parking under state law, but the city investigates unpermitted conversions, so we take every project through Planning and Building and Safety with proper insulation, egress and fire separation.
Room Additions in Santa Clarita
A ground-floor addition suits the single-story homes in Valencia's early villages and Canyon Country's 1960s neighborhoods, where the yard has room to grow into. We check HOA architectural rules, keep footings and trenches clear of any oak's protected zone, and tie the new roof, stucco and slab into the existing house so the addition reads as original.
Second-Story Additions in Santa Clarita
Going up keeps the yard intact on the tighter tract lots of Saugus and Valencia. Every second story we build starts with a structural engineer's review of the existing footings and framing, which matters in a valley the 1994 Northridge earthquake shook hard. We also plan cooling for the upper floor from the start, since summer afternoons here regularly pass 100 degrees.
Garage Construction in Santa Clarita
New detached garages make the most sense on the larger lots of Sand Canyon, Placerita Canyon and older Newhall, where owners want room for trailers, a shop or a unit above. In mapped fire zones, Los Angeles County Fire reviews fuel modification for certain accessory buildings over 120 square feet, and we build that review, and any oak tree permit, into the schedule.
Whole-House Remodeling in Santa Clarita
Homes in Valencia's earliest villages, first occupied in 1967, and in Canyon Country's 1960s neighborhoods such as Lower North Oaks are often due for new wiring, plumbing, windows and insulation at the same time. A whole-house remodel lets us open up those original floor plans while bringing systems and energy performance up to current California code in one permitted project.
Kitchen Remodeling in Santa Clarita
A kitchen remodel in a Saugus or Valencia tract home often means taking down a wall to the family room, which needs an engineer to confirm whether that wall carries load. We handle that, along with relocated plumbing and gas lines, new circuits for modern appliances, the city permit, and HOA review when windows or exterior vents change.
Bathroom Remodeling in Santa Clarita
We remodel primary and guest bathrooms throughout the valley and build the bathrooms that go inside new ADUs and garage conversions. Each one gets a proper waterproofing system behind the tile, an exhaust fan sized for the room and plumbing brought up to current code, all under a City of Santa Clarita permit and inspection.
Fire Rebuilds in Santa Clarita
Parts of the valley lie in fire hazard severity zones, and CAL FIRE's 2025 maps expanded the very high zones in the Santa Clarita Valley. When a home here is lost or badly damaged, we rebuild to current wildfire construction standards and coordinate the Los Angeles County Fire fuel modification plan the new house will need before permit.
Junior ADUs (JADU) in Santa Clarita
A junior ADU of up to 500 square feet carved out of a spare bedroom or an attached garage is often the simplest way to add a family suite or small rental in a Santa Clarita home. The city's ADU rules allow one alongside a detached ADU, and the owner must live in either the main house or the junior unit.
SB 9 Lot Splits & Duplexes in Santa Clarita
Under SB 9, a qualifying Santa Clarita single-family parcel may take a second primary home or be split into two lots. Santa Clarita's SB 9 guidance asks for one fully enclosed garage space for each unit in a two-unit project, which shapes the site plan early. We build the units once the lot qualifies and the design is approved.
Patios, Decks & Outdoor Living in Santa Clarita
Shade earns its keep in a valley with summer highs that can top 100 degrees. We build solid and open patio covers, outdoor kitchens and decks sized for how you use the yard, and on fire-zone lots we choose ignition-resistant materials and keep new structures consistent with the property's fuel modification plan.
Local Knowledge
What Shapes a Building Project in Santa Clarita
Santa Clarita incorporated on December 15, 1987, joining Canyon Country, Newhall, Saugus and Valencia into one city, and the four still feel distinct. Newhall is the oldest core: silent film star William S. Hart bought his ranch there in 1921, and Old Town Newhall now has a specific plan with its own standards for renovations and infill. Valencia is a planned town. Newhall Land adopted its master plan, drawn with urban planner Victor Gruen, in 1965, and the first residents moved in during 1967. Its villages are linked by paseos, and many are governed by homeowner associations.
Saugus and Canyon Country grew tract by tract. Bouquet Canyon, the original Saugus, holds more than 40 separate tracts beginning with the Bonelli tract of the early 1950s, and Canyon Country mixes 1960s neighborhoods with newer planned communities such as Fair Oaks Ranch. Placerita Canyon and Sand Canyon remain rural, with equestrian properties on large lots.
Addresses inside city limits are permitted by the City of Santa Clarita Building and Safety Division at City Hall on Valencia Boulevard, usually after Planning Division clearance. Nearby unincorporated communities such as Stevenson Ranch and Castaic go through Los Angeles County instead, so we confirm jurisdiction before design begins.

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
Building in Santa Clarita: Common Questions
Is my address permitted by the City of Santa Clarita or by Los Angeles County?
It depends on where the lot sits. Addresses inside city limits in Canyon Country, Newhall, Saugus and Valencia go through the City of Santa Clarita Building and Safety Division, usually after Planning clears the project. Unincorporated parts of the valley, including Stevenson Ranch and Castaic, go through Los Angeles County Public Works, which runs its own Santa Clarita Valley office. We confirm this first because the rules and reviewers differ.
Does my Valencia HOA need to approve an addition or ADU?
In most villages with an association, yes, at least for exterior changes. Many Valencia neighborhoods are governed by homeowner associations with architectural review. We read the CC&Rs early, prepare the drawings the committee needs, and time the HOA submittal so it runs alongside the city's plan check instead of holding it up.
How do oak trees on my lot affect a building project?
Santa Clarita protects oak trees on private property. Cutting, pruning, removing or even encroaching into an oak's protected zone requires an oak tree permit. That zone starts 5 feet outside the dripline and is never less than 15 feet from the trunk. We locate every oak on the survey before design so foundations, trenches and grading stay clear, or so the permit becomes part of the plan.
Will fire zone rules change my project?
They can. In areas served by Los Angeles County Fire, new construction, remodels of 50 percent or more, and certain accessory structures over 120 square feet inside a fire hazard severity zone need an approved fuel modification plan before the building permit is approved. We check your parcel against the current CAL FIRE maps at the start.
