Frequently asked questions
Adding an addition to your existing home is generally more cost-effective than building a new house. Home additions make use of existing infrastructure and utilities, which can significantly reduce costs. However, the total expense will depend on the size and complexity of the addition, as well as the materials used.
The cheapest type of home addition is typically a single-room extension, such as a sunroom or a small bedroom. These additions require less structural work and fewer materials compared to multi-room additions or second-story expansions. Costs can be further minimized by choosing cost-effective materials and designs.
The timeline for home additions varies depending on the project’s scope and complexity. On average, a small addition like a single room can take 3-4 months, while larger projects, such as adding a second story, can take 6-9 months. Detailed planning and efficient project management are crucial to staying on schedule.
In Redmond, ADUs are subject to the following:
- Size: Maximum of 1,000 sq. ft. or 40% of the primary dwelling’s floor area.
- Parking: One additional parking space required.
- Compliance: Must meet all construction and zoning standards.
More details can be found at the Redmond City Government website.
