Black Diamond Drafting & Design creates permit-ready ADU plans for Riverside homeowners, from detached and attached units to garage conversions, along with custom homes and additions. Each set is drawn for the City of Riverside Building & Safety Division, with structural and Title 24 sheets coordinated in one submittal.

Projects Completed For Homeowners & Companies Across Coachella Valley



Our team is here to deliver drawings your contractor can use to build and your city will approve. We even coordinated Structural, Title 24 energy, mechanical, electrical and plumbing sheets into one complete set, so nothing reaches plan check in pieces.
Four steps from first call to issued permit, with a clear schedule at every stage.
01
Tell us about your Riverside property and the ADU, addition, or home you want to build.
02
We contact you to confirm setbacks, utilities, and parking, and whether an attached, detached, or garage conversion unit fits your lot.
03
We draft permit-ready plans that match your goals and aesthetic, with structural and Title 24 sheets included.
04
Once you approve, we submit to the City of Riverside Building & Safety Division and respond to plan check until the permit is issued.
Request an ADU estimate to get started. We confirm what your Riverside lot allows before drafting, so your plans are right the first time and your build stays clear of costly redesigns.
