SD Plastering Company
ADU Stucco Contractor San Diego | SD Plastering Company
San Diego's ADU boom has flooded the market with builders learning stucco on the fly. We've been doing it correctly for 40 years. Whether you're building a detached ADU in Carmel Valley, converting a garage to a JADU in Clairemont, or adding an attached ADU in Escondido, SD Plastering Company delivers the only thing that actually matters: a finish that matches your existing home, passes inspection on the first walk, and doesn't crack two summers later.
Stucco for New Detached ADUs
For ground-up detached ADUs we install full three-coat hard-coat stucco systems with proper WRB, lath, and expansion joints. We coordinate directly with your ADU general contractor or, for owner-builders, drop into the schedule between framing inspection and final. We hit the dates your permit timeline requires.
Matching Existing Home Stucco on ADU Additions
An ADU addition that doesn't visually match the main house tanks resale value and rental appeal. Our color and texture matching is the single best in San Diego — we hand-blend integral pigment, replicate the exact finish (smooth, cat-face, lace, float, dash), and feather the new stucco into the existing wall so there's no visible seam.
Garage Conversions & JADU Stucco
Most garage conversions involve filling in the old garage door opening — which is where 90% of contractors leave an ugly scar. We rebuild the wall assembly correctly, integrate WRB and lath into the surrounding fabric, and finish so seamlessly you genuinely cannot tell where the garage door used to be.
Permit Compliance & ADU Inspection
San Diego's ADU permit process requires code-compliant exterior wall assemblies. We install ASTM C1063-compliant lath, two-layer Grade D paper, proper expansion joints, and weep screeds — every detail your inspector will look for. Most of our ADU stucco walls pass first inspection.
Why Stucco Consistency Matters for ADU Resale & Rentals
For owners building ADUs as rental income or future resale, a visually consistent exterior is the difference between a clearly tacked-on addition and a property that looks intentional and well-built. Tenants, appraisers, and future buyers all notice. We make sure they notice favorably.
