Home Building questions, answered by experts

Yes, home builders need to be licensed in every state and municipality in the country. The specific license required varies based on the location and the work, but most states require that the builder hold a general contractor’s license at minimum. Some states and cities also require that plumbing, electrical, roofing, and sewage system construction require individual licenses, in which case the builder may subcontract the work. You can use Angi’s contractor licensing tool to confirm that the builder you’re considering holds all the proper licenses.

Most contractors aim for about a 20% profit on a job, leaving themselves room for unexpected expenses or delays. After accounting for materials, labor, and insurance, the profit margin for most contractors is between 10% and 20%. Fluctuating costs of materials and labor affect the ultimate percentage.

Prefab kits like a small sunroom for around $20,000 or even a basic gazebo roof for as little as $60 can save you big over professional installation. However, you lose the option for customization, and these structures tend not to last nearly as long. As for bigger projects like a deck or patio, you shouldn’t go with the DIY route unless you’re fully prepped with the tools and know-how to get it done right. Mistakes can be frustrating and costly, so choose a pro if you’re looking to eliminate your risk of error.

Yes, you can finance new construction using a construction loan or a construction-to-permanent loan, or you can use a home equity line of credit or a cash-out refinance if you’re building a second home. Some mortgagors may have restrictions on DIY house builds, so be sure to check that you can get financing before starting your project.

Building a house is generally more expensive upfront than moving an existing one. However, the total cost depends on factors such as location, size, materials, labor, and permits. Moving a house can incur significant expenses for transportation, permits, site preparation, and renovations. On the other hand, building a new house allows for customization and may have lower long-term maintenance costs.
