ADU Construction in Granada Hills
Granada Hills ADUs drawn with clearances, rated walls and ember-resistant details set out for LADBS plan check, built by Fernhill Builders.
Clearance around the new walls is what an LADBS examiner reads first on a Granada Hills ADU set when the parcel lies on mapped fire hazard ground. The site plan has to show how far the unit stands from the house, the fences and each lot line, and what covers the ground in between. We draw those distances and surfaces into the first submittal, so plan check can move on to framing and the shell.
Walls near a lot line
Any wall of the unit that stands within a few feet of a property line needs a fire-resistance rating and limits on its openings, whatever the hazard map says. On a mapped parcel the rest of the shell follows the state wildfire chapter as well: noncombustible or ignition-resistant cladding, listed vents, tempered glazing and enclosed eaves. Our wall sheet ties each of those items to a numbered detail, and the window schedule flags the openings that face a close lot line. An examiner can match a callout to its detail in one step, which keeps the correction letter short.
Answering plan check
Comments are routine on ADU sets, so we plan for them from the start. Our office reads each one, revises the affected sheet and returns the set with a reply that points to every change by sheet and note. Questions about fire access, hydrant reach or sprinklers on a mapped Granada Hills parcel come straight to you, with what each possible answer would mean for the scope and the schedule. You get a copy of every letter and every reply, so the permit's status is always in front of you.
ADU Construction in Granada Hills: common questions
Yes, wherever the parcel sits inside the mapped zone, and the rules reach the roof as well as the walls: a Class A covering, enclosed eaves, listed vents, tempered glass and ignition-resistant siding. A Granada Hills lot outside the map can still take the same shell as an option. We confirm the address against the state map before the first sketch.
On a Granada Hills set we spend the most drafting time on the site plan, where clearances to fences and lot lines are drawn for a parcel that may sit on mapped ground. Its scope is a single-story ADU that qualifies under the size cap, and anything taller or wider is priced as its own job.
Usually that can work. When the rebuild and the unit travel on one permit path, both sets can be reviewed side by side and their inspections lined up. We look at the lot, the rebuild drawings and the space between the two buildings, then tell you whether to file together or one after the other.
