Frequently Asked Questions

How do Mascord differ from "Architects"?

Our talented professional building designers create stunning unique home designs with neccessary code-compliant details to obtain permits and construct your home. We create detailed structural & permit documents that a general contractor follows to build your custom home.

However, where an Architect would source and list everything for your custom home (down to the nails and wall color) - we leave the sourcing and finite specification of and finishes to you and your builder. That helps you to maintain flexibility with choices, and greatly reduces the costs of creating the design.

With over 30 years' of award winning design experience, there are more than 65,000 families enjoying their Mascord homes. Join them, and get in touch with us today!

How much does a customized home plan cost?

Where a full service architect could typically charge a percentage of the total cost of construction, our custom design and modication services are instead afraction of that cost, based on an hourly rate to make changes to your chosen design. Because the costs of our services are not based on the value of the home being designed - you can expect to save thousands over the usual costs of hiring a full-service Architect.

Do the plans include everything I need to get a building permit?

Our home plans are detailed to meet IRC (International Residential Code) requirements, and also Oregon and Washington local code amendments. Some areas require additional information, such as wind and seismic calculations, or energy code compliance worksheets. If you need any of these special items, we can work with professionals we have relationships with to provide them cost effectively, or you are welcome to use your own.

In addition, our construction support staff can assist you with questions or concerns from your building department - making the permiting process run smoothly. Some issues, unique to your situation, may incur additional costs.
