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 the East Valley.
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 East Valley cities now permit ADUs on single-family lots, though setback requirements, lot coverage limits, and parking rules vary by city. We conduct a zoning review before any estimate, so you know exactly what's buildable on your specific lot before committing to anything.
Absolutely. If you have permitted drawings or architect plans, we build from them. If you're starting from scratch, we can connect you with residential design professionals we've worked with and coordinate the full design-build process.
