When you love your neighborhood but need more space, a home addition lets you grow without moving. But additions are among the more variable remodeling projects, cost-wise, because they involve foundation, framing, roofing, and finishing all at once. Here's what East Valley homeowners should budget.
Home addition cost ranges
| Addition type | Ballpark cost |
|---|---|
| Bump-out (small extension) | $20,000 – $50,000 |
| Single-room addition (bedroom/office) | $45,000 – $100,000 |
| Primary suite addition | $90,000 – $180,000 |
| Second-story or multi-room addition | $150,000 – $300,000+ |
What drives the cost
- Square footage and whether it's single- or second-story
- Foundation and structural work
- Matching the existing roofline, stucco, and finishes
- New plumbing, electrical, and HVAC extension
- Permits, engineering, and HOA approvals
- Finish level of the new space
Is an addition worth it versus moving?
In competitive East Valley markets, moving means paying today's prices plus agent fees, closing costs, and the disruption of relocating. For many families, adding the exact space they need — a suite, an office, a bigger living area — is both cheaper and keeps them in the school district and neighborhood they chose. Permitted, licensed work also protects that investment at resale.
Additions require permits
Because additions involve structural, electrical, and often plumbing work, they require permits and inspections — and frequently HOA architectural review. We handle the engineering, permitting, and construction as one coordinated project with a fixed price.
