Home Addition Construction in Beaverton, OR

How much you can build depends on your lot's zoning designation, setback requirements, and maximum lot coverage, which typically runs 40 to 50 percent of the lot area in Beaverton residential zones. Side setbacks are commonly five feet, and rear setbacks vary, so the buildable area on your specific parcel determines what size addition is possible.

Temporary weatherproofing is used to protect the open wall or roof connection between your existing home and the new addition during construction. Keeping the interior of your Beaverton home dry and secure during that phase is a standard part of how we plan the build sequence.

Yes, matching the roofline pitch, siding material, and exterior trim to your existing home is a core part of how we design additions in Beaverton and across the west side. A well-matched addition should look like it was always part of the original structure, not something tacked on later.

Adding on lets you keep your Beaverton neighborhood, school district, and lot while gaining the space you need, without the transaction costs of selling and buying. For many homeowners, building out or up is the more direct path to the square footage they want.

In many Beaverton communities, yes. Neighborhoods like Sexton Mountain and Progress Ridge require a Design Review Committee application that covers exterior materials, colors, and structural changes before work begins. We identify your HOA requirements at the start of the project so the design is built for approval, not revised after the fact.

Beaverton zoning rules set minimum setbacks from property lines, maximum lot coverage percentages, and building height limits that all cap how large an addition can be. These rules vary by zone across the city, and some parcels with a Beaverton address actually fall under Washington County jurisdiction, which has its own separate standards.
