ADU Plans in Los Angeles: The Woodland Hills Plans Package and What It Covers

A search for ADU plans Los Angeles from a house in Woodland Hills usually means an owner is ready to pay for drawings and wants to know what that money buys. Cedarline Design Build sells a plans package from $8,350 on a qualifying one-story ADU up to 500 sq ft, and that figure buys drawings only, with construction priced separately. Here is what sits inside the package, what falls outside it, and how we decide which price applies to your parcel.

Tell us the address, the ADU type and the floor area you have in mind, and ask whether your unit qualifies for the package. We answer once we have reviewed the lot.

Drawing a unit for one Woodland Hills parcel

A plan set has to answer to a single property. Setbacks, easements, an old garage and the route to the sewer all limit where the walls can go, so our drawing starts after someone has looked at the lot. Across the San Fernando Valley we begin with the open yard behind the house, since that measurement decides whether a detached unit is on the table at all.

The lot review sets detached, attached, garage conversion and JADU next to each other. The type you choose goes to drawings, and the ADU construction page explains how each one differs.

Owners in Los Angeles city limits will also come across standard plans. LADBS runs a Standard Plan Program that lists ADUs among its uses, and a pre-approved design shortens the time spent in plan check. The department also says holding one does not remove the need for a building permit, and that it still reviews how the design fits your property, including zoning and foundation needs. So a pre-approved design leaves the site work, utility routes and fit to the lot still to be drawn and priced. If one suits your yard, we will price that path as well.

What moves the price of ADU drawings

Six things decide which plans price you see on page one of our quote.

• Floor area and stories. One story and up to 500 sq ft can qualify for the package. A bigger footprint or a second story falls outside it, and we write the drawing price for that unit after the review.
• Unit type. A garage conversion has to be measured as it stands. An attached unit has to be drawn against your existing wall and roof line. Each type asks for different sheets.
• Engineering the lot calls for. If the rear yard slopes, the foundation may need a soils report or a short retaining wall, and that reaches the structural sheets.
• Records you already hold. A survey and old permits cut down the measuring. Without them, we find those facts on site.
• Late changes. Moving a window after the structural work is drawn means redrawing it. Settling the layout early keeps this line small.
• What the drawings do not pay for. City fees, school and utility charges and the build itself each take a separate line.

The plans line stands alone on the quote and holds the drawings, structural calculations and energy forms. If your unit qualifies, the package figure goes there. If some part of your set falls outside it, the line says so before you commit.

Who should draw it, and who answers for it

Plans sold apart from a builder leave the build price open until bids come back. When those bids run high, you may pay a second time to reduce the set. We draw and build under one contract, so a costly feature shows up as a priced line while it is still ink. Our comparison of design build and separate contracts sets out both paths, and some owners do prefer an architect on a large custom project.

Before you pay anyone for ADU drawings, ask these:

• Who looks at the actual lot before drawing starts?
• Are structural calculations and energy forms part of the fee?
• Who answers the city when corrections come back, and does that cost extra?
• Can you tell me what this set will cost to build, and when?
• If the build price runs over my budget, who pays for the redraw?

Already holding a set from another designer? Bring it. We review drawings against the current rules and the cost to build, then tell you what would need to change. And if the household needs more room instead of a second home, our room additions page weighs that choice on your lot.

From lot review to a set we can price

1. Parcel review and visit. We read the records, then walk the yard, measure to the property lines, find the sewer cleanout and open the panel.
2. Type comparison. All four types go on one sheet for your Woodland Hills lot, along with what each would involve.
3. Plans price. You learn whether the package applies. Otherwise we write the drawing price for the unit you picked.
4. Drawings and budget. We draw the unit and show you the construction lines as the plan develops.
5. Plan check. We submit the set, answer the corrections and keep the file moving until the permit is issued.
6. Construction contract. The build price follows the drawings you approved.

Each step has its price in front of you before it starts. You can pay for the review and the drawings first, then fund construction once that number is known.

Papers and photos that speed up the drawing

Have these close by when we talk.

• The property address, plus any survey or old site plan.
• Earlier permits or drawings for the house and the garage.
• The floor area and room count you want, even as a rough sketch.
• Photos of the yard, the side access and the panel with its cover on.
• Any pre-approved design you have been looking at.
• Whether family or a tenant will live in the unit.

Start with the address

Call us or send the form with the address and the size you want. We review the lot, tell you which plans price applies and set out what comes after the drawings.
