- Weather is a major factor that can affect the construction timeline. Builders can’t work in dangerous conditions, and they don’t want to put the construction materials or workers at risk. Depending on where you live, you can plan to build during a milder season, as long as your contractor is available. - Availability of materials doesn’t just affect the budget; if there are shortages it can delay construction and extend your timeline. - Availability of contractors determines when you can start your project. Although it could take time to find the perfect contractor for your project, it’ll pay off to wait for the right builder. - Inspections are an essential part of the homebuilding process, and often your builder can’t move to the next step without an inspection. Having a clear timeline, open communication with your builder, and planning ahead for inspections can help you stay on track, but some delays may be inevitable.
