About
Planning projects in Arizona
Arizona homeowners experience some of the country's most diverse environmental conditions, from low desert heat and monsoon storms to cool mountain forests and snowy high elevations. Intense sunlight, dry air, seasonal dust, and limited water shape everyday decisions about roofing, stucco, cooling systems, exterior finishes, and landscaping. Higher elevations introduce additional considerations such as wildfire preparedness, freeze-thaw cycles, and winter weather. Understanding how these regional differences affect your home can help you choose materials and maintenance strategies built to thrive in Arizona's climate.

Insurance requirements
Workers' comp is required for any employer, even with one part-time worker. Residential bonds are $9,000 to $15,000 for general contractors and $4,250 to $7,500 for specialty contractors. The Residential Contractors' Recovery Fund pays homeowners up to $30,000 per claim. No general liability minimum was found.
Rules vary by city and county. Confirm with your local building department.
Permit rules
Cities and counties adopt codes and issue permits. Residential contracts over $1,000 must be in writing, with the license number, price, payment schedule and a notice of the right to complain to the ROC.
Rules vary by city and county. Confirm with your local building department.

Common questions about hiring a contractor
Consider the direction the windows face, available exterior shade, and how much solar heat the glass will admit. Large east- or west-facing windows can bring substantial heat and glare into a room, especially in Arizona’s hotter desert communities. Compare solar heat gain coefficient ratings alongside insulation performance, and discuss shading as part of the design. Window choices for a Phoenix home may differ from those for a colder, higher-elevation location.
If the system can remain in service, plan those improvements together before choosing replacement equipment. Changes to insulation, air sealing, windows, and shading can reduce the home’s cooling needs. Ask the HVAC contractor to size the new system for the home’s planned condition rather than simply matching the existing unit. Arizona’s summer heat makes reliable cooling important, but buying a larger system does not automatically produce better comfort.
New paving, raised planting beds, and changes in ground level can redirect runoff toward the house or obstruct an existing drainage route. Before work begins, ask how water will move across the finished property during a heavy storm, including where roof runoff will go. If the project includes rainwater harvesting, locate collection areas so they do not concentrate water against the foundation. Include drainage in the design before the layout and elevations are finalized.
