ADU Builder & Contractor in Granada Hills, CA

Granada Hills lots are among the largest in the Valley for an ADU: 7,000–10,000 sq ft tracts around Balboa Boulevard with a detached garage, parcels up to 20,000 sq ft in Old Granada Hills, and RA and RE estate lots north of Rinaldi. The tract garages convert to a 400–480 sq ft unit; the larger lots take a full 1,200 sq ft detached unit, often with its own driveway approach, and the equestrian lots keep the setbacks that come with the zone.

The typical site is a 7,000–10,000 sq ft tract lot south of Rinaldi with a detached garage, or a Knollwood hillside parcel where slope and the Specific Plan set the design. What decides between a garage conversion, a JADU and a detached unit is that lot, the sewer route and the main panel: 100-amp panels in most 1950s–60s houses; a 200-amp LADWP upgrade is part of most full kitchens. Every unit gets a full kitchen and bath, its own sub-panel and, for a detached unit, its own address.

One contract covers the whole job: a licensed architect draws the plans, a structural engineer stamps them, we file with LADBS and answer the corrections, and our own crew builds through final inspection and the Certificate of Occupancy. Our office is in Valley Glen, about 25 minutes away, and the project lead who does the feasibility visit runs the build.

Granada Hills climbs from the flat tracts around Balboa Boulevard and Chatsworth Street up into Knollwood and the foothills north of Rinaldi, with Old Granada Hills and its walkable Chatsworth Street village on the west, Granada Hills Charter High School in the middle and O'Melveny Park, the city's second-largest park, at the top. Our office is in Valley Glen, about 14 miles south by the 405, a 25-minute drive, and the LADBS counter that reviews Granada Hills permits is the Van Nuys Development Services Center on Van Nuys Boulevard.

Two overlays shape the north side: the Granada Hills Specific Plan governs the estate and hillside parcels north of Rinaldi, and the Baseline Hillside Ordinance adds grading and access review on the slopes of Knollwood, so a detached unit there is designed around the pad and the driveway before anything else. South of Rinaldi the flats are straightforward LADBS review, and where the lot fits, the pre-approved Standard Plans shorten plan check. There is no rail transit in Granada Hills, so a new detached unit usually keeps its one parking space; we confirm that and the sewer route at the feasibility visit.

An ADU in Granada Hills is permitted through LADBS (City of Los Angeles) at the Van Nuys Development Services Center under ministerial review, which approves a code-compliant unit without a public hearing, and the utility connections go through LADWP. Units under 750 sq ft pay no impact fees, a garage conversion needs no replacement parking, and the unit can be rented on leases of 30 days or more once the Certificate of Occupancy is issued.
