Local Knowledge, Local Results
Why Sunnyvale HomeownersChoose True Builders.
Sunnyvale has one of the Bay Area’s largest concentrations of Eichler homes, and the city protects their character: Eichler neighborhoods have their own design guidelines, and some areas are zoned single-story only. That shapes what’s possible — a second-story addition may be off the table, while a rear addition, atrium-friendly kitchen remodel or backyard ADU fits well. We work through those rules with Sunnyvale’s Community Development Department before design is finalized.
Every project comes with a fixed construction price and a single project manager.

Sunnyvale Permits & Rules
What to Know Before You Build in Sunnyvale.
We handle every permit. Here's the short version of what Sunnyvale typically requires for common projects:
- Eichler homes — Exterior changes are reviewed against Sunnyvale's Eichler design guidelines, which favor low-slope roofs, simple materials and privacy for neighbors.
- Single-story areas — Some neighborhoods carry a single-story zoning designation that limits additions to one story. We check your parcel's zoning first.
- ADUs — Approved ministerially under state law; detached ADUs must meet height limits and 4-foot side and rear setbacks.
- Kitchen & bath remodels — Permits are needed for plumbing, electrical and structural changes, and most residential applications run through the city's One-Stop Permit Center.
- Heritage housing — Homes in the Taaffe-Frances Heritage Housing District near downtown require added design review for exterior work.

SUNNYVALE FAQS
Local Questions, Answered.
It depends on your neighborhood. Some Sunnyvale Eichler areas are zoned single-story only, while others allow second stories with design review. We check your parcel before any design work.
The type of ADU matters most: converting a garage usually costs far less than building a new detached unit. After that, size, utility trenching and the sewer connection, foundation and soil conditions, and finish level drive the price. We give you a fixed price after a free site visit.
Often somewhat. Post-and-beam structure, radiant slab heating and walls of glass need specialized framing, insulation and HVAC solutions, which we plan and price up front.
Most kitchen remodels take 6–12 weeks of active construction depending on complexity, plus a few weeks beforehand for design, selections and permitting.
Scope is the biggest factor. A same-layout refresh, a signature remodel with semi-custom cabinetry and layout changes, and an estate-level custom kitchen are very different projects. Moving plumbing, gas lines or walls, cabinetry and countertop selections, appliances and city permit fees also play a role. We give you a fixed price after a free site visit.
Plans and permits typically take 8–14 weeks, and construction of a detached ADU usually takes 16–22 weeks once permits are issued, so most detached ADUs are finished in about 6–9 months. Garage conversions and JADUs are usually faster.
