What to Know About New Construction in Atherton
Local building codes, neighborhood character, and permit requirements vary by city. Here's what Atherton homeowners should know before starting a project.
- 01Atherton requires a minimum lot size of 1 acre in most residential zones, with maximum FAR (floor-area-ratio) limits that typically cap buildable square footage around 25-30% of lot area
- 02The Town of Atherton Heritage Tree Ordinance protects oaks over 12" diameter — new home footprints must be designed around protected trees, and an arborist report is required before grading permits are issued
- 03Atherton has no commercial zones and no sidewalks — all construction traffic, material staging, and dumpster placement must be coordinated carefully on the property to avoid impacting narrow residential roads
- 04Many Atherton properties rely on septic systems rather than municipal sewer; new construction requires San Mateo County Environmental Health approval for septic design and capacity
- 05The Town of Atherton building department is small and thorough — plan check for new construction typically takes 10-14 weeks, and projects may require Planning Commission review for homes exceeding certain thresholds

New Construction in Atherton: FAQ
Answers to common questions from Atherton homeowners.
A custom new home in Atherton typically takes 18-30 months from architectural design through completion. This includes 4-6 months for design and engineering, 3-4 months for permitting, and 12-18 months of construction. Larger estates with guest houses, pools, and extensive landscaping may take 24-36 months total. Barcci Builders provides a detailed milestone schedule at contract signing.
Custom new construction in Atherton ranges from $600-$1,200+ per square foot depending on finishes, complexity, and site conditions. Ultra-luxury builds with imported stone, custom millwork, and smart home integration typically fall in the $800-$1,200/sf range. Our fixed-price contracts lock in costs before construction begins.
If renovation costs would exceed 60-70% of new construction costs, or if the existing layout fundamentally doesn't work, demolish-and-rebuild is usually the better investment. In Atherton, where land value represents the majority of property value, a new build lets you optimize the home for the lot, meet current energy codes, and incorporate modern systems without the compromises inherent in renovation.
In 2026, Atherton's most sought-after new builds feature California contemporary design — flat or low-slope rooflines, floor-to-ceiling glass, natural materials like cedar cladding and natural stone veneer, indoor-outdoor living with disappearing walls, and warm earthy palettes. Modern farmhouse and transitional styles with clean lines also remain popular.
Yes. The Town of Atherton's building department reviews all new construction for compatibility with neighborhood character, setback compliance, height restrictions (typically 30 feet), and Heritage Tree impact. Larger projects may go before the Planning Commission. Barcci Builders manages the entire entitlement and permitting process.
Absolutely, and we recommend it. California's building codes increasingly favor electrification. We design all-electric homes with heat pump HVAC, heat pump water heaters, induction cooking, solar-ready roofing, EV charging in the garage, and battery backup systems. These homes exceed Title 24 energy requirements and offer lower operating costs with zero on-site emissions.
