Frequently Asked Questions
Get answers to common questions about home renovation projects and our process.
Most home additions require building permits, especially those involving structural changes, electrical work, or plumbing. Minor cosmetic updates typically don't require permits, but it's always best to check with your local building department. Room additions, second stories, and garage conversions all require permits.
Permit approval times vary by jurisdiction and project complexity. Simple additions may be approved in 2-3 weeks, while complex projects can take 6-8 weeks or more. Factors affecting timeline include completeness of application, seasonal demand, and whether revisions are required during plan review.
Building without permits can result in stop-work orders, fines, and legal complications. You may be required to tear down completed work, obtain retroactive permits at higher costs, and face delays in selling your home. It's always better to get proper permits before starting construction.
Property owners can typically apply for their own permits, but many choose to have their contractor handle the process. Contractors are familiar with local requirements and can navigate the process more efficiently. Some jurisdictions require licensed contractors for certain types of work.
Typical inspections include foundation/footing, framing, electrical rough-in, plumbing rough-in, insulation, and final inspection. Some jurisdictions may require additional inspections. Inspections must be scheduled in advance and passed before proceeding to the next construction phase.
Permit costs vary widely based on project value and local fees. Building permits typically range from $500-2,000, electrical permits $150-500, and plumbing permits $200-600. Total permit costs usually represent 1-3% of the total project cost. Contact your local building department for specific fee schedules.
