From Whittier and Hacienda Heights over to Walnut, Diamond Bar, West Covina and La Habra Heights, the parcels that ring Rowland Heights get the same ADU process we bring to Rowland Heights itself. One feasibility visit, one side by side look at detached, attached, garage conversion and JADU, and one set of drawings prepared for plan check. Only the agency reading the plans changes between them, and for this community it is the county.

One sequence on every parcel

Each job starts with a walk of the lot and a measured sketch of the house, the yard, the driveway and any structure already standing. We locate the sewer cleanout, read the electrical panel label and note where the water line enters. Those readings let us place every unit type on the sketch and see which ones clear the setbacks with room left for a path to the door. The same checklist runs whether the address is in Rowland Heights or a neighboring city, so the steps and their order never depend on the address.

Review by Los Angeles County

Los Angeles County runs plan check for a Rowland Heights unit, since the community is unincorporated. The county applies state ADU law through its own zoning code, which sets the setbacks, height and parking terms the drawings have to meet. Its examiners send back written comments, and we answer each one on revised sheets before a permit is issued. On an inland suburban lot we also specify a light roof color, attic insulation and low gain glass wherever windows face the afternoon sun, and those choices are part of the set from the first submission.
