Frequently Asked Questions


What Zoning Restrictions Should I Look Into?

While local zoning laws will inevitably vary, you should always check to see if any restrictions pertain to your property. Depending on the goal of the project, a home addition can add substantial space to your house, so make sure you're allowed to build within the requisite measurements. A building department consultation is essential as there are also height restrictions and other rules to consider.

How Much Should I Expect to Spend?

Your overall costs will depend on the type of addition you have in mind. To get an exact estimate, you'll have to set up a meeting with us. You can either Call or Email us here. Don't forget to account for long-term expenses, as well. If your home increases in size, your energy bills and property taxes will follow suit. As long as you're realistic about costs in the beginning, you'll be less likely to run into any bank-breaking surprises.

Will I See a Return on My Investment?

Once you have your budget figured out, another big question arises: Will this project add any value to your home? You should always think about resale value and return on investment, but keep in mind that additions typically yield less return than traditional remodels.
