New Construction in Chandler
The Chandler Market
Chandler's residential new construction market is primarily ADU-driven — the city's updated ADU ordinance has made it attractive to add a casita for rental income, a guest suite for family, or a home office detached from the main structure. We've navigated Chandler's ADU approval process many times and can give you a realistic picture of what's buildable on your specific lot.
Room additions in Chandler are common in neighborhoods built in the 1990s–2000s where homeowners want more space but don't want to move. Adding a primary suite, expanding a kitchen into a sunroom, or converting a detached garage into living space are all projects we execute regularly.
All Chandler new construction and addition work requires permits through Chandler Development Services. Commercial residential permits typically run 3–6 weeks for review. Cosmo manages the full permit process, coordinates all required inspections, and doesn't start work until the permit is in hand.

Common Questions
Chandler allows ADUs on single-family residential lots subject to setback requirements (typically 5-foot side/rear setbacks for detached ADUs), maximum size limits (usually 50% of primary dwelling or a fixed maximum square footage), and parking requirements. Chandler Development Services handles ADU permits. We conduct a zoning review before any estimate so you know exactly what's buildable on your lot.
Chandler Development Services typically processes ADU permit applications in 3–6 weeks, depending on drawing completeness and current review volume. We submit complete, code-compliant drawings to minimize review comments and resubmittal cycles.
