Plans, Permits & Design in Agoura Hills
Architectural drawings, structural engineering, Title 24 and full permit management. Designed, permitted and built by our own crews.
Plans, Permits & Design built for Agoura Hills properties
Nearly every backyard we design here backs onto something protected — an oak grove, a slope, a fuel-modification buffer at the edge of the Santa Monica Mountains. That shapes the work. Pool shells get sited around root protection zones instead of through them, outdoor kitchens get non-combustible cladding, and grading is kept close to natural contour. We plan Agoura Hills projects around the oak survey and the slope map before anyone picks a finish.
A mix of flat tract parcels with modest rear yards near the valley floor and half-acre-plus equestrian and hillside properties with slope, oaks and long driveways in the older ranch areas.
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 Agoura Hills: Residential permits are issued by the City of Agoura Hills Building and Safety Division, with planning and architectural review handled in the same Community Development Department. The oak tree preservation ordinance protects any oak with a trunk diameter of two inches or more and establishes a protected zone extending five feet beyond the dripline, so grading, trenching or paving near a canopy requires an oak tree permit. Parcels in or partly in a designated hillside area need architectural review approval or a conditional use permit before a building or grading permit can issue. CAL FIRE's March 2025 local responsibility area maps place the large majority of the city in high or very high fire hazard severity zones, which drives defensible space and exterior material requirements.

Local Conditions
What building in Agoura Hills actually involves
Every city in Southern California builds differently. These are the things that change the scope, the schedule or the budget on Agoura Hills projects.
Decomposed granite and clay-rich hillside soils vary sharply within a single parcel, so pool shells and detached structure foundations usually need a project-specific soils report rather than a standard detail.
Mature coast live oaks sit close to houses, and their protected zones extend five feet past the dripline, which pushes excavation, trenching and equipment staging away from the canopy.
Sloping rear yards mean retaining walls and deepened footings are often the first line item on a backyard budget rather than an upgrade.
Fuel-modification requirements along the wildland edge shape plant palettes, decking material and any shade structure inside the defensible-space band.
Investment
What this costs in Agoura 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 Agoura 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.
Agoura Hills Questions
Common questions from Agoura Hills homeowners
Who issues the permits for this work in Agoura Hills?
City of Agoura Hills Community Development Department, Building and Safety Division. Residential permits are issued by the City of Agoura Hills Building and Safety Division, with planning and architectural review handled in the same Community Development Department. The oak tree preservation ordinance protects any oak with a trunk diameter of two inches or more and establishes a protected zone extending five feet beyond the dripline, so grading, trenching or paving near a canopy requires an oak tree permit. Parcels in or partly in a designated hillside area need architectural review approval or a conditional use permit before a building or grading permit can issue. CAL FIRE's March 2025 local responsibility area maps place the large majority of the city in high or very high fire hazard severity zones, which drives defensible space and exterior material requirements. 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 Agoura Hills different?
A mix of flat tract parcels with modest rear yards near the valley floor and half-acre-plus equestrian and hillside properties with slope, oaks and long driveways in the older ranch areas. In practice that means decomposed granite and clay-rich hillside soils vary sharply within a single parcel, so pool shells and detached structure foundations usually need a project-specific soils report rather than a standard detail..
Which parts of Agoura Hills do you work in?
All of it, including Old Agoura, Morrison Ranch, Lake Lindero, Liberty Canyon. We are based in Los Angeles at Cahuenga Pass, so Agoura 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 Agoura 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.
