Streamline Design & Permitting, Llc

What Streamline Design & Permitting, Llc does

Streamline Design & Permitting, LLC is a privately held California professional services firm founded in February 2022 by architect Devin Way and headquartered in Escondido. The company delivers residential and light commercial design, drafting, feasibility, and building permit services, with a pronounced specialization in Accessory Dwelling Units (ADUs) — including detached, attached, garage conversions, basement, and Junior ADUs — alongside whole-house remodels, room additions (including second-story and bump-outs), kitchen and bathroom redesigns, custom home design, code compliance and forensic drafting, unpermitted ADU legalization, and commercial tenant improvements. Core technical work is performed in CAD drafting software, augmented by California Energy Commission-approved CBECC-Res and EnergyPro for Title 24 energy calculations producing CF1R and registered energy compliance documentation. Service delivery is supported by 3D rendering and visualization, CAD conversion (PDFs/scans to DWG/DXF), and ADU feasibility studies reviewing zoning, site conditions, and utilities.

The firm's go-to-market is sales-led and consultation-driven, offering free initial consultations and project-specific estimates with no upfront costs; fees are quoted as a percentage of total project construction cost, typically 3-4%. Customer segments are primarily individual homeowners seeking ADUs, remodels, or additions, with secondary segments including residential property developers (multi-family ADU projects) and light commercial establishments (tenant improvements). Distribution is exclusively direct via phone, in-person meetings at the Escondido office, and website-driven lead capture, supplemented by a referral network of vetted local contractors and interior design subcontractors and reciprocal preferred-partner relationships with Builders Now, Gottik, ProSource Wholesale, and TLK Builders.

The firm operates across four Southern California counties — San Diego, Riverside, Orange, and Los Angeles — and reports 45+ permitted projects since founding and 20+ projects completed annually. The leadership team brings 25+ years of combined industry experience, anchored by the founder's Bachelor of Architecture from NewSchool of Architecture and Design and supported by a Director of Sales. The firm holds BBB accreditation and memberships in BIA, NARI, and the Casita Coalition, and is recognized as a preferred partner in the California State ADU Handbook. The company is privately held with no disclosed external institutional investment, no parent company, and no subsidiaries.

Scale indicators5 records

Recent moves6 records

Emerging players

• Yardzen: Online design platform that has expanded into backyard and ADU design services, including permit-ready plans. Adjacent competitor for homeowners beginning their ADU journey, with a tech-led rather than local-expert delivery model.

Broad incumbents

• Mighty Buildings: Construction-technology company producing prefab ADUs and homes with integrated design and permitting. Operates in California and competes for the same end customer segment, though with a prefab rather than custom design model.
• Dvele: Design-driven modular home builder in California with integrated design, engineering, and permitting for custom residences and ADUs. Competes with Streamline on the custom home design and ADU permitting side of the market.
• Plant Prefab: California-based prefab home and ADU manufacturer offering design-build services including permitting. Overlaps with Streamline's ADU permitting capability but delivers standardized factory-built units rather than fully custom plans.
• Abodu: Prefab ADU manufacturer that bundles design, permitting, and installation in California. Competes for the same ADU buyer but with a standardized product offering and faster delivery, making it a broader incumbent to Streamline's customized design/permit service.

Direct peers

• Avava: California ADU-focused company combining architectural design, permitting, and construction services. Closely comparable service mix to Streamline, particularly for homeowners seeking permit-ready ADU plans in Southern California.
• SnapADU: California-based ADU design and permitting specialist offering similar end-to-end ADU services (design, engineering, permit management) to homeowners. Closest comparable in business model and customer segment to Streamline Design & Permitting.
• Cover: Tech-enabled ADU company that combines design, permitting, and prefab construction in California. Directly competes for the same homeowner ADU customer with an integrated offering, though Cover's prefab delivery differs from Streamline's design-and-permit core.
