ADU Construction in San Dimas
Whether a detached ADU fits behind a San Dimas house, or a garage conversion or JADU suits it better, is settled by measuring the lot and the utilities.
Will a detached unit even fit behind my San Dimas house, or am I really looking at a garage conversion or a JADU? That is the question our feasibility visit is built to answer. We measure the lot, find the sewer and the power, and lay all four ADU types side by side against the setbacks, so the answer rests on the parcel and the rules that apply to it.
How fit is measured
A detached cottage needs clear space at the rear and side lot lines, distance from the main house and a path to its door that meets access rules. We measure each of those on site and draw them onto a scaled sketch. An attached unit trades some of that yard space for a shared wall and a shorter utility run. A garage conversion uses a footprint that exists already, and a JADU stays inside the house within its size limit. Seeing all four outlines on one sketch shows which ones the lot can hold.
Utilities and the San Dimas review
Fit is also a matter of what can reach the unit. We open the cleanout to learn the depth and direction of the sewer lateral, then check whether waste from the planned spot can flow to it by gravity or needs a pump. Reading the panel and running a load calculation tells us if a subpanel will do. For an inland lot the roof covering and window glass are picked to limit heat gain. The City of San Dimas reviews the drawings against state ADU law and its zoning, and city inspectors approve the work stage by stage up to the final.
