ADU Construction for Woodland Hills Homeowners
ADU construction in Woodland Hills makes use of something the neighborhood has plenty of: postwar lots with room behind the house. We design, permit and build detached backyard units, attached ADUs and garage-based units, coordinating plans, engineering, utilities and LADBS inspections from start to finish.
The City of Los Angeles has permitted at least 26,862 ADUs since statewide legalization, and in one recent year about one in three homes it permitted was an ADU. That volume means the permit path is well worn. It does not make every lot simple, and in Woodland Hills the details that decide cost are usually heat, slope and utility capacity.
Local Knowledge
ADU Planning on Woodland Hills Lots
The flats north of Ventura Boulevard are the easiest ground for a backyard unit. Tracts like Woodland West were laid out along curving streets, so rear yards are often wedge-shaped or irregular, and the best footprint is not always a rectangle tucked in the back corner. State law guarantees at least an 800 square foot ADU with 4-foot side and rear setbacks, and detached units can generally reach 1,200 square feet.
Walnut Acres is a different case. Its RA-zoned lots are large enough for a full-size detached unit with its own entry path and yard, and owners there sometimes weigh an ADU against a barn or workshop for the same patch of ground. On hillside parcels south of Ventura, the unit usually sits on a graded pad or steps down the slope, and fire zone construction rules apply to it just as they do to the main house.
Every Woodland Hills ADU needs a heat plan. A single-story unit with a low roof absorbs afternoon sun, so we specify strong roof insulation, a light-colored roof where it suits the design, shaded glazing and a heat pump matched to the unit's actual load.
What's Included
What's Included in an ADU Build
- Feasibility review of setbacks, utility locations, sewer connection and any hillside or fire zone overlay
- Design coordination for a detached, attached or above-garage unit sized to your goals
- Structural and energy engineering, plus soils engineering on sloped lots
- LADBS permit submittal and responses to plan check corrections
- Utility work including electrical service capacity, water, sewer lateral and gas where used
- Construction through final inspection, with insulation and cooling sized for west Valley summers

Planning Considerations
Woodland Hills ADU Considerations
Size and impact fees
State law exempts ADUs under 750 square feet from impact fees, and that threshold is worth weighing against the space a larger unit provides. A well-planned one-bedroom can stay under it. A two-bedroom unit near 1,200 square feet will not, but it may suit a family member or a long-term tenant far better. We price both versions before you commit to a design, so the trade-off is clear.
Height and neighbors
Detached ADUs are generally limited to 16 feet, which suits the low profile of Woodland Hills Ranch neighborhoods. On a lot that backs onto other yards, we place windows and doors with privacy in mind, since a unit only 4 feet from the property line sits close to a neighbor's patio. A careful layout avoids friction that can outlast construction by years.
Electrical capacity
Many older houses here still have electrical panels sized for a smaller load than a modern home plus an ADU requires. Adding a heat pump, induction cooking and an EV charger can push the service past its rating. We evaluate the panel and the utility service early, because an upgrade that involves the utility runs on its own schedule, separate from ours.
Why Choose Us
Why Woodland Hills Homeowners Choose Simply Construction
Contracts Written the Way California Law Requires
California caps a home improvement down payment at $1,000 or 10 percent of the contract price, whichever is less, and after that a contractor may only bill for work completed or materials delivered. Our contracts follow that structure: a line-item scope, a payment schedule tied to finished milestones, and written change orders before any extra work begins. You always know what you are paying for and why.
Permits Handled With LADBS
Most delays on large residential projects start at the permit counter. We prepare the drawing set, coordinate structural and Title 24 energy calculations, answer plan-check comments and schedule inspections with LADBS, so you are not the one chasing corrections. For ADUs, state law requires the agency to act on a complete application within 60 days, and a complete, well-coordinated submittal is what starts that clock.
Care for Your Street and Your Neighbors
Large projects happen next door to people who live there. We plan staging, dumpster placement, deliveries and working hours around Woodland Hills rules, keep the site secured at the end of each day, and give you notice before loud or disruptive phases such as demolition, concrete pours or crane lifts, so you can give your neighbors a heads-up too.

FAQ
ADU Construction in Woodland Hills: Common Questions
How long does the city have to approve an ADU permit in Woodland Hills?
State law requires the city to act on a complete ADU application within 60 days. The clock starts when the application is complete, so we put effort into a clean first submittal with structural and energy calculations attached. Correction rounds, when they happen, are where most of the time goes.
Is a hillside lot a problem for an ADU?
Not necessarily, but it needs more homework. We look at slope, street access, the fire hazard designation and whether the city's hillside rules affect grading or placement. A soils report may be required for the foundation. We tell you early whether the site is workable and what it will take to build there.
Will a backyard unit stay comfortable in August?
It will if it is built for it. We use roof insulation that goes beyond the minimum where it pays back, windows with a low solar heat gain rating on sunny exposures, and overhangs or exterior shading where the design allows. The heat pump capacity comes from a load calculation for that specific unit, not a guess based on square footage.
