Do I need a stucco contractor for my ADU permit in San Diego?

Yes. San Diego building inspectors require code-compliant lath, weather-resistive barrier, and weep screed inspections prior to applying scratch and brown coats.

Can you match my existing stucco on an ADU addition?

Yes. We hand-blend color pigments and trowel test boards against your existing main home wall until texture and color match exactly.

How long does ADU stucco take from start to finish?

Most standalone ADUs take 5 to 10 working days including cure windows between coats.

Do you work with owner-builders on ADUs or only GCs?

We work directly with both owner-builders managing their own permits and licensed general contractors.

Will the garage-door infill on a JADU be visible after stucco?

No. We integrate new paper and lath with the surrounding wall and feather the finish coat so the former opening is completely invisible.

Scope & Capabilities

What We Do

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. Compare finishes in our stucco finish styles guide.

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. If the surrounding stucco is cracked, our stucco repair crew fixes that first.

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.
