Built for Stevenson Ranch Homes
Stevenson Ranch is one of the West Ranch communities of unincorporated Los Angeles County, a master-planned neighborhood west of Interstate 5 and north of Pico Canyon Road that was built out in phases under a plan approved by the County. To the south, Pico Canyon holds Santa Clarita Woodlands State Park and the historic oil town of Mentryville, and the County's area plan notes significant stands of oak trees around West Ranch's developed areas.
With no city government of its own, Stevenson Ranch takes its building permits from County Public Works and its zoning from County Title 22, and inside the Stevenson Ranch HOA an Architectural Committee must approve pools, spas, hardscape and landscaping in writing before work begins.
Fire mapping sets much of the rest of the brief: about four in five single-family lots fall in a Very High Fire Hazard Severity Zone, which brings a County Fire landscape review into new structures and large additions and can narrow the ADU options on those lots.
Master-planned tract homes built out in phases, nearly all between 1987 and 2004 according to LA County Assessor records. Assessor parcel data puts the median single-family lot near 7,800 square feet, with the middle half between roughly 6,300 and 10,000 square feet, and most lots are zoned either RPD (Residential Planned Development) or R-1.
We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, CSLB license #1119054 .
Permits in Stevenson Ranch: Stevenson Ranch is unincorporated, so building permits come from County Public Works through its Santa Clarita district office on Valencia Boulevard, and zoning follows County Title 22 rather than a city code. About four in five single-family lots fall in a Very High Fire Hazard Severity Zone on the current state maps; there, a new structure, an addition equal to at least half the existing square footage, or certain accessory structures over 120 square feet need a County Fire fuel modification plan approved before the building permit.
Under Title 22 Section 22.140.640, a lot in a Very High Fire Hazard Severity Zone as depicted in the County General Plan can add only a state-exempt ADU, meaning a conversion of existing space or a detached unit of up to 800 square feet with four-foot side and rear setbacks, unless it has two separate, non-overlapping vehicular routes to a highway, each at least 24 feet wide, or fronts a highway with direct vehicle entry.
Within the Stevenson Ranch HOA, pools, spas, hardscape, landscaping and patio covers also need written Architectural Committee approval before work starts.

Local Conditions
What to Know in Stevenson Ranch
These local conditions change the scope, the schedule and the budget.
01
About four in five single-family lots are mapped Very High Fire Hazard Severity Zone and more than nine in ten sit in a fire hazard zone of some severity; where a fuel modification plan applies, its zones out to 30, 100 and 200 feet from each structure, or to the property line, govern planting and layout.
02
More than a quarter of single-family parcels fall inside a state-mapped earthquake-induced landslide zone and about one in ten inside a liquefaction zone on the Newhall and Oat Mountain quadrangles, so soils findings belong at the start of pool and structure design.
03
An oak at least eight inches in trunk diameter, measured four and a half feet above grade, has a County protected zone reaching five feet beyond the dripline or 15 feet from the trunk, whichever is greater; encroaching into it takes an Oak Tree Permit, and approved digging there can be limited to hand tools or small power equipment.
04
In any Fire Hazard Severity Zone a County ADU must sit at least 200 feet from publicly dedicated open space, although the rule still allows a unit of 800 square feet with four-foot side and rear setbacks, which matters on lots that back onto open space.

Questions
What Stevenson Ranch Homeowners Ask
Who issues the permits for this work in Stevenson Ranch?
Los Angeles County Public Works, Building and Safety Division (Santa Clarita District Office). Stevenson Ranch is unincorporated, so building permits come from County Public Works through its Santa Clarita district office on Valencia Boulevard, and zoning follows County Title 22 rather than a city code.
About four in five single-family lots fall in a Very High Fire Hazard Severity Zone on the current state maps; there, a new structure, an addition equal to at least half the existing square footage, or certain accessory structures over 120 square feet need a County Fire fuel modification plan approved before the building permit.
Under Title 22 Section 22.140.640, a lot in a Very High Fire Hazard Severity Zone as depicted in the County General Plan can add only a state-exempt ADU, meaning a conversion of existing space or a detached unit of up to 800 square feet with four-foot side and rear setbacks, unless it has two separate, non-overlapping vehicular routes to a highway, each at least 24 feet wide, or fronts a highway with direct vehicle entry.
Within the Stevenson Ranch HOA, pools, spas, hardscape, landscaping and patio covers also need written Architectural Committee approval before work starts. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.
What makes building in Stevenson Ranch different?
Master-planned tract homes built out in phases, nearly all between 1987 and 2004 according to LA County Assessor records. Assessor parcel data puts the median single-family lot near 7,800 square feet, with the middle half between roughly 6,300 and 10,000 square feet, and most lots are zoned either RPD (Residential Planned Development) or R-1.
One local condition that shapes the work: About four in five single-family lots are mapped Very High Fire Hazard Severity Zone and more than nine in ten sit in a fire hazard zone of some severity; where a fuel modification plan applies, its zones out to 30, 100 and 200 feet from each structure, or to the property line, govern planting and layout.
Which parts of Stevenson Ranch do you work in?
All of it, including Westridge, Diamondhead, Marblehead and Pacific Colony. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.
What does a pool or spa project cost in Stevenson Ranch?
New pool construction: generally $70,000 to $150,000+ across Southern California. What moves it is size and shape, spa, water and fire features, decking material, automation, and how much access and grading the site needs. We give line-item pricing after seeing the site rather than quoting a number over the phone.
How long does a pool remodel take?
A straightforward replaster with new tile and coping usually runs three to five weeks. A full remodel that includes new decking, equipment and features typically runs eight to twelve weeks. Site access and permit timing are the two things that move that most.
How long does a new pool take to build?
Most new pool builds run about three to five months from permit to first swim. Hillside sites that need engineered retaining or difficult access sit at the longer end of that range.
Should I replaster or fully remodel?
If the shell and plumbing are sound and you only dislike the surface, replastering with new tile and coping is the efficient choice. If the equipment is aging, the deck is cracked or the shape no longer suits how you use the yard, a full remodel costs less than doing it in two separate phases.
Do you self-perform the work?
Yes. Our own crews handle the build rather than passing it to a rotating set of subs, which is why the schedule and the finish standard stay consistent.

Before You Build in Stevenson Ranch
Costs, materials and process notes from our own projects.
Building a Pool in Northridge: Costs and Permits A new pool in Northridge typically runs $85,000 to $165,000 all-in with decking and equipment. The tract lots are generous, the soil is workable, and the real variables are access, spa and deck square footage. Read guide Van Nuys Pool and Backyard Costs A new pool in Van Nuys runs $75,000 to $145,000, and a pool-plus-backyard package $110,000 to $220,000. Flat lots keep excavation honest; older service panels and gas meters are where budgets slip. Read guide Travertine vs Porcelain Pavers for SoCal Yards Travertine installs at roughly $22 to $30 per square foot, porcelain at $24 to $34. The real difference is heat, staining and how each one handles a chlorinated pool deck over ten years. Read guide Pool Coping Options: Concrete, Stone and Porcelain Coping runs $28 to $55 per lineal foot in concrete, $55 to $110 in natural stone and $60 to $120 in porcelain. On an average pool perimeter that is a $2,500 to $11,000 decision. Read guide
