ADU Construction in La Cañada Flintridge
Serving 91011 · 91012 and Pasadena, Glendale, Altadena
An accessory unit is new construction, and in La Cañada Flintridge new construction on a sloped parcel is exactly what the hillside permit exists to review. Lots here are frequently large, which helps — but large and flat are not the same thing.
New structures on foothill lots
Slope decides the path
If the parcel averages fifteen percent slope or more, a Hillside Development Permit applies to work requiring a building permit. Establishing which side of that line your lot falls on is the first useful thing anyone can do.
Usable ground, not total area
On foothill parcels the relevant measure is buildable, accessible ground in the right place — not the size of the lot on paper. That is a site assessment, and it is quick.
Stated plainly
We have not built an accessory unit in this city. Ranges we publish for this work are market estimates rather than our own completed-project record, and we would rather label them than imply otherwise.
Drainage downhill of the unit
On a slope, where water goes after it leaves the new building is a real design question. Getting drainage and grading right protects both the unit and everything below it, and it is not somewhere to economise.
