Architectural drawings, structural engineering, Title 24 and full permit management. Designed, permitted and built by our own crews.
Plans, Permits & Design built for Granada Hills properties
Granada Hills splits cleanly for us at Rinaldi. South of it, we are working flat postwar tracts with straightforward access and aging services. North of it, the ground tilts, the brush starts, and hillside grading limits and fire-zone construction requirements come into play. Balboa Highlands adds a third case entirely — the Eichler tract carries historic design review, so exterior changes there get handled as a preservation project, not a standard remodel.
Flat 7,000 to 10,000 square foot postwar lots dominate the southern half, while the northern foothills hold larger, sloping parcels with view orientation and descending rear yards that need retaining before they are usable.
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 and insured, LIC #1119054.
Permits in Granada Hills: LADBS issues residential building, grading and pool permits here, with plan check and inspection handled through the Van Nuys Development Services Center. North of Rinaldi Street the terrain rises and many parcels fall in the city's designated hillside area, bringing Baseline Hillside Ordinance (No. 184,802) grading quantity, height and retaining wall limits, while foothill properties near the Santa Susana Mountains sit in or beside Very High Fire Hazard Severity Zone mapping with brush clearance and Chapter 7A obligations. The Balboa Highlands tract, the 1962-64 Joseph Eichler subdivision designated in 2010, is a Historic Preservation Overlay Zone, so exterior alterations there require HPOZ design review through Los Angeles City Planning. Oaks and other protected species are common on the north side and need an Urban Forestry permit before removal or encroachment, and review length varies.

Local Conditions
What building in Granada Hills actually involves
Every city in Southern California builds differently. These are the things that change the scope, the schedule or the budget on Granada Hills projects.
The ground transitions from flat alluvial tract land in the south to sloping foothill terrain with shallow bedrock in the north, and an identical pool design prices very differently across that line.
Foothill streets narrow and steepen, which limits excavator size, gunite hose runs and concrete truck access on upper-elevation properties.
Postwar tracts in the flats commonly need a main panel upgrade and a sewer lateral assessment before pool equipment, a spa heater or a second dwelling is added.
Mid-century post-and-beam homes on slab floors require careful detailing where new openings, decks or additions meet the original structure and its exposed beams.
Investment
What this costs in Granada Hills
Real Southern California ranges, not a teaser number. Every project is priced line by line after we have seen the site.
Plans, drawings and permit management
$4,500 to $25,000+
What moves it: project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved
Detached ADU
$150,000 to $400,000+
What moves it: square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build
Retaining walls
$60 to $150 per face foot
What moves it: height, whether the wall is engineered, material choice, drainage behind the wall, and access for equipment and materials
How We Build
Your Granada Hills project, step by step
Feasibility
We check zoning, setbacks, easements and utilities to confirm what the property will actually support before you spend on drawings.
Survey & As-Builts
The site and existing structure are measured and drawn so the permit set starts from reality, not an old plot plan.
Design Development
Plans and elevations developed to the level of detail plan check expects, with 3D so you can see it clearly.
Consultants
Structural engineering, Title 24 and, where the site needs it, a soils report are coordinated into one set.
Submittal
We make the submittal and act as the applicant, so correspondence with the city comes to us rather than to you.
Corrections & Issue
We respond to plan-check corrections, resubmit, and see the permit through to issue.
Granada Hills Questions
Common questions from Granada Hills homeowners
Who issues the permits for this work in Granada Hills?
Los Angeles Department of Building and Safety (LADBS). LADBS issues residential building, grading and pool permits here, with plan check and inspection handled through the Van Nuys Development Services Center. North of Rinaldi Street the terrain rises and many parcels fall in the city's designated hillside area, bringing Baseline Hillside Ordinance (No. 184,802) grading quantity, height and retaining wall limits, while foothill properties near the Santa Susana Mountains sit in or beside Very High Fire Hazard Severity Zone mapping with brush clearance and Chapter 7A obligations. The Balboa Highlands tract, the 1962-64 Joseph Eichler subdivision designated in 2010, is a Historic Preservation Overlay Zone, so exterior alterations there require HPOZ design review through Los Angeles City Planning. Oaks and other protected species are common on the north side and need an Urban Forestry permit before removal or encroachment, and review length varies. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing the city.
What makes building in Granada Hills different?
Flat 7,000 to 10,000 square foot postwar lots dominate the southern half, while the northern foothills hold larger, sloping parcels with view orientation and descending rear yards that need retaining before they are usable. In practice that means the ground transitions from flat alluvial tract land in the south to sloping foothill terrain with shallow bedrock in the north, and an identical pool design prices very differently across that line..
Which parts of Granada Hills do you work in?
All of it, including Balboa Highlands, Knollwood, Granada Hills North, Granada Hills South. We are based in Los Angeles at Cahuenga Pass, so Granada Hills is a short run for our crews rather than a job we service from out of the area.
What does plans, permits & design cost in Granada Hills?
Plans, drawings and permit management in this market generally runs $4,500 to $25,000+. What moves it is project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved. We give line-item pricing after seeing the site rather than quoting a number over the phone.
Can you do the plans without doing the build?
Yes. Plans and permits is a service we sell on its own, and plenty of clients use us for the drawing set and permit management and build with someone else. We would rather do it properly than tie it to a construction contract.
Why do permit costs vary so much?
Because the required consultants vary. A straightforward patio cover needs a modest set. An ADU on a sloped lot may need structural engineering, Title 24, a soils report and a survey, and each of those is a separate specialist fee on top of the city's own plan-check and permit charges.
What causes plan-check corrections?
Most commonly incomplete structural detail, missing Title 24 forms, drainage not shown, or a discrepancy between the site plan and the survey. Corrections are normal, not a failure. The thing that costs time is a slow response to them, which is why we act as the applicant.
Do you handle HOA approval too?
Yes, where a community requires it. HOA architectural review runs on its own calendar and its own standards, entirely separately from the city, and starting it late is one of the most common reasons a project slips.
