ADU Specialists Since 1984
ADU Stucco Contractor San Diego | Stucco for ADUs, Garage Conversions & New Builds
San Diego's ADU boom has flooded the market with general contractors learning stucco on the job. SD Plastering Company has been hand-troweling exterior stucco for 40 years — and ADUs are now one of our largest workloads. We deliver permit-ready, seamlessly matched, on-schedule stucco for detached ADUs, JADUs, attached additions, and garage conversions across all of San Diego County.
What ADU Stucco Work Actually Involves
An ADU's exterior stucco is what makes the unit look like a permanent, intentional part of the property — or like a tacked-on backyard shed. Done correctly, ADU stucco involves proper weather-resistive barrier installation behind the lath, code-compliant ASTM C1063 lath spacing, foundation-level weep screed, expansion joints engineered for the wall geometry, and a finish coat that matches the main house's texture and color precisely. Done badly, it cracks within a year, leaks at the trim, and visually screams "addition." We've spent four decades doing it correctly.
Types of ADUs We Serve in San Diego
We handle every flavor of San Diego ADU: ground-up detached units (typically 400–1,200 sq ft), attached additions to the main house, junior ADUs (JADUs) carved out of existing interior space, full garage-to-living-space conversions, and second-story pop-up additions. Each comes with its own stucco challenges — detached units need full three-coat new construction stucco, conversions require seamless infill where the garage door used to be, and attached additions demand perfect color and texture matching at the seam.
The San Diego ADU Permit Process and How Stucco Fits In
San Diego permits ADUs under the city's streamlined ADU ordinance, with required inspections at framing, lath, and final stages. The lath inspection in particular trips up inexperienced contractors — improper paper laps, missing weep screed, or non-compliant lath spacing all fail. We install to spec the first time, document everything photographically, and coordinate directly with your inspector so the project never sits idle waiting on stucco re-work.
Matching Existing Home Stucco on ADU Additions
This is where most ADU projects visually fail. We hand-blend integral pigment color on-site (not bagged premix), produce sample boards for owner approval, and replicate the original finish style — whether that's 1980s heavy lace, 1990s cat-face, modern smooth Santa Barbara, fine float, dash, or English cottage. The new ADU stucco feathers into the existing wall so cleanly that future buyers and appraisers can't tell where the addition begins.
Cost Factors for ADU Stucco in San Diego
Square footage is the biggest driver, but other factors matter: finish complexity (smooth Santa Barbara takes more skilled labor than dash), color matching requirements, site access (steep lots and tight setbacks cost more), elastomeric topcoat upgrades, stone veneer accents, and whether the ADU is detached or requires matching into an existing wall. Expect $8,500–$22,000 for most detached ADUs and $4,500–$12,000 for garage conversions and JADUs.
Why Hire a Stucco Specialist Instead of Letting the GC Handle It
General contractors are excellent at managing trades — they are not (usually) excellent at hand-troweled plaster. Stucco is one of the few residential trades where specialist skill genuinely shows in the final product. The best ADU GCs in San Diego know this and sub stucco out to specialists like us. The result is faster inspections, better finishes, and zero callbacks.
