New Construction in Granada Hills
Granada Hills new homes sequenced from a hazard map lookup to survey, soils, design and LADBS review, with an ADU placed in the first layout.
Our sequence for a Granada Hills house puts a parcel lookup ahead of the first sketch. Some Granada Hills parcels lie on maps of fire hazard severity, and building on one of those can bring ember-resistance rules that reach the roofing, vents, eaves and glazing. Settling that question early lets the design, the ADU placement and the budget all start from one set of rules, so nothing has to be redrawn after plan check.
From parcel check to permit
Once the hazard question is answered, a licensed surveyor fixes boundaries and existing grades, and a geotechnical engineer drills borings to describe what the footings will bear on. The architect draws around those two documents, then the structural and energy consultants size beams, footings, insulation and equipment from that set. Cost is reviewed at each pass while changes are still lines on paper. LADBS plan check comes next, along with the fire department's look at hydrant reach and access where it applies. A house already on the lot is demolished under a separate permit once gas and power are cut at the street.
Where the ADU enters the order
A second unit fits most easily when its footprint is drawn in the same round as the main house. Placing it then lets one trench carry water, sewer and power to both buildings, and lets the driveway, side paths and access widths serve each one. State ADU law and the City of Los Angeles zoning code set how close the unit may sit to the rear and side lines and how tall it can be. On a parcel the hazard map covers, the unit takes the same ember-resistant roof, vents and siding as the house, which keeps a single specification for both.
New Construction in Granada Hills: common questions
Drawing the unit into the first layout is the stronger plan whenever zoning allows one on the lot. Its utility stubs, its own entry path and its windows can be set while everything is still movable, and one grading plan covers both pads. Adding it later can mean cutting fresh trenches across a finished yard.
The parcel's hazard mapping is confirmed, a surveyor records lines and contours, and the geotechnical borings are logged. Design, engineering and cost review then lead to an LADBS submittal. Any old structure comes down under its own demolition permit after utility shutoff, and the excavator stays off the lot until LADBS releases the building permit.
For a Granada Hills lot, the California Residential Code governs structure, the Energy Code sets insulation, glazing and rooftop solar requirements, and CALGreen covers water use and construction waste. Mapped parcels add the wildfire construction chapter. City of Los Angeles zoning and grading rules decide height, setbacks and how the site drains.
