What to Know About New Construction in Los Altos
Local building codes, neighborhood character, and permit requirements vary by city. Here's what Los Altos homeowners should know before starting a project.
- 01Los Altos enforces FAR limits that cap buildable square footage relative to lot size — on a typical 10,000 sf lot, maximum home size is approximately 3,500-4,500 sf depending on the specific zoning district and calculations
- 02Several Los Altos neighborhoods have a strong single-story character, and the City's design review may require significant second-floor setbacks, reduced massing, or hip roofs on two-story proposals to maintain neighborhood compatibility
- 03Los Altos has a protected tree ordinance covering heritage oaks and other significant specimens — removal requires City approval, replacement planting, and in some cases in-lieu fees
- 04The Los Altos building department typically completes plan check in 6-8 weeks for new residential construction, with design review adding 4-8 weeks depending on project complexity and neighbor response
- 05Demolition permits in Los Altos require an asbestos survey and abatement certification for any structure built before 1980 — this adds 2-3 weeks and $3,000-$8,000 to the project timeline

New Construction in Los Altos: FAQ
Answers to common questions from Los Altos homeowners.
Custom new construction in Los Altos typically takes 14-24 months from design through completion. This includes 3-5 months for architectural design and engineering, 2-4 months for design review and plan check, and 10-16 months of construction. Projects requiring additional design review iterations or involving complex sites may extend the timeline. Our fixed-price contract includes a detailed milestone schedule.
Yes, two-story homes are permitted in Los Altos, but the City's design review process carefully evaluates second-floor massing, privacy impacts on neighbors, and compatibility with the existing neighborhood character. In predominantly single-story neighborhoods, you may need to reduce second-floor footprint, use hip roofs to minimize visual bulk, and carefully place windows to avoid direct sightlines into neighboring yards. We design with these criteria from the initial concept.
Custom new construction in Los Altos ranges from $450-$850+ per square foot depending on finishes, site conditions, and design complexity. Homes with premium finishes — imported stone, custom millwork, high-end appliances, smart home systems — typically fall in the $600-$850/sf range. Our fixed-price contracts give you budget certainty before construction begins.
In 2026, Los Altos buyers favor warm contemporary designs that respect the neighborhood's residential character — clean lines with natural wood and stone accents, generous indoor-outdoor living, and earthy palettes. California contemporary, modern farmhouse, and transitional styles that bridge traditional proportions with contemporary details are all well-received by the City's design review process.
Los Altos design review evaluates new construction for neighborhood compatibility, building mass and scale, privacy impacts, tree preservation, and overall design quality. The process involves submittal of architectural drawings, story pole installation for two-story homes, a neighbor notification period, and review by the Planning Commission. Our team prepares comprehensive submittals and addresses potential concerns proactively to streamline approval.
In Los Altos, where land represents 70-80% of total property value, demolish-and-rebuild is often the better investment when renovation costs approach 50-60% of new construction costs. A new build gives you a modern foundation, current energy systems, optimized floor plan, and full code compliance — without the compromises inherent in working around old structure. We can evaluate both options during a free consultation.
