Local Knowledge, Local Results
Why Atherton HomeownersChoose True Builders.
Large lots bring larger responsibilities. The Town of Atherton’s heritage tree ordinance shapes where you can build, estate-scale projects involve detailed engineering and utility planning, and neighbors expect construction to be managed carefully. We plan tree protection, staging, drainage and long utility runs up front, and keep one project manager accountable for schedule, quality and communication throughout.
Every project includes a fixed construction price once plans are complete.

Atherton Permits & Rules
What to Know Before You Build in Atherton.
We handle every permit. Here's the short version of what Atherton typically requires for common projects:
- Heritage trees — Atherton protects heritage trees; removal requires a Town permit, and construction nearby requires protection measures and often an arborist report.
- Large-lot zoning — Floor area, height and setback limits depend on lot size; we confirm what your parcel allows before design.
- Guest houses & ADUs — ADUs are approved ministerially under state law, while larger accessory structures follow the Town's zoning standards.
- Construction management — Larger projects may require construction staging, parking and neighbor-impact plans.
- Remodels — Permits are required for structural, plumbing, electrical and mechanical work.

A complete home redesign usually takes 8–12 months or more.
Yes. We coordinate custom cabinetry, stone, millwork and specialty trades, with selections tracked against the budget throughout design and construction.
It depends on scope: remodeling select spaces such as the kitchen and bathrooms takes about 4–5 months, a comprehensive remodel with structural changes 6–8 months, and a complete home redesign 8–12 months or more.
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.
