Site Development Permit

Submit plans for Site & Architectural Commission review. Commission evaluates compatibility with neighborhood character, visual impact, and compliance with design guidelines.

4

Building Permit Application

Submit final plans to Building Department with all studies complete. Plans must show grading strategy, tree preservation, and material/color specifications.

5

Construction & Inspections

Why Local Expertise Matters

Monte Sereno's design guidelines, permit process, and hillside constraints are unlike standard residential development.

Strict Design Guidelines

Every home must respond to its setting, minimize visual impact, and preserve natural contours. Our designs respect these principles from day one.

Multi-Stage Approval

Site Development Permit approval comes before the building permit. Architects, geologists, and commission review happen early, preventing costly redesigns.

Environmental Sensitivity

Tree preservation, slope protection, and minimal grading aren't just rules—they define the community. We build that respect into every project.

Design Review & Approvals: A Closer Look

The Monte Sereno Site & Architectural Commission reviews all projects exceeding 120 square feet or adding 500+ square feet in smaller zones.

What the Commission Evaluates

Neighborhood Compatibility: Does the design fit the area's character? Architectural style, scale, and materials must align with surrounding homes.

Visual Impact: How does the home sit on its lot? Building height, placement, setbacks, and view preservation are critical in hillside areas.

Design Guideline Compliance: Architecture must be consistent with Monte Sereno's published design guidelines emphasizing horizontal lines, open space, and natural materials.

Slope & Grading: Minimum grading and retention of natural contours are mandatory. Steep slopes and drainage swales must remain undisturbed.

Neighbor Consultation Matters

Early communication with neighbors can smooth the approval process. Concerns addressed upfront often prevent delays and challenges at the commission hearing.

Frequently Asked Questions

Do I need design review approval before I apply for a building permit?

Yes. Monte Sereno requires a Site Development Permit (design review) approval before the building permit is issued for most residential projects.

What happens if my project affects trees on the property?

Tree removal or projects that encroach on tree canopy require a certified arborist report evaluating tree health and safety. Tree preservation is a key design guideline.

What's the difference between the R-1-8, R-1-20, and R-1-44 zones?

These zones define minimum lot sizes and setbacks. R-1-8 requires 8-acre minimum lots; R-1-20 requires 20 acres; R-1-44 requires 44 acres. Addition size requirements vary by zone.

Can I repair or replace my roof without a permit?

You can repair up to 10 percent of roof area without a permit. Anything beyond that or a full replacement requires a permit. Hillside homes often need Class A fire-rated roofing materials.

How important is it to reach out to neighbors before I submit plans?

Very important. Early neighbor discussion often prevents disputes, minimizes challenges, and speeds commission approval. It's a best practice we strongly recommend.
