What We Build
Why It Matters
Building new in Arizona comes with specific challenges — caliche soil layers that require different foundation approaches, extreme summer heat that affects concrete cure schedules, and municipality-specific permit timelines that vary significantly across Phoenix.
Cosmo has been navigating all of it since the 1990s. We've built across Chandler, Queen Creek, Gilbert, and Mesa — each with their own development services offices, inspection cadences, and zoning requirements. We don't outsource the coordination; we handle it directly.
Every custom home builds project includes a detailed written estimate, a fixed-scope contract, and a clear construction schedule. KB-2 licensed · ROC#335649 · Bonded & Insured.

Common Questions
A typical custom home build runs 8–14 months from permit approval to certificate of occupancy, depending on size, complexity, and municipality. Permit approval timelines vary — Chandler Development Services typically runs 4–8 weeks for residential custom home builds. We give you a full construction schedule at the start of the project.
Yes. All Phoenix cities now permit ADUs on single-family lots, though setback requirements, lot coverage limits, and parking rules vary by city. Start with our East Valley ADU permit guide; we then conduct a zoning review so you know what's buildable on your specific lot before committing.
Absolutely. If you have permitted drawings or architect plans, we build from them. If you're starting from scratch, our step-by-step custom home planning guide explains the path from lot selection through construction, and we can coordinate the full design-build process.
