On the Peninsula, the approval path is often the real project schedule. Building permits, grading and drainage review, design review boards, heritage tree ordinances, fire-zone rules, and HOA architectural committees each run on their own calendars, and they decide when your project actually starts. This 2026 playbook explains the most common approval layers and selected high-impact town rules for outdoor projects in San Mateo and Santa Clara Counties, so you can plan the calendar honestly before you fall in love with a design.
Educational only (not legal advice). Permit triggers, tree ordinances, and review requirements are jurisdiction-specific and change. Always verify current requirements with your local Authority Having Jurisdiction (AHJ). Town references were checked against official sources in July 2026.
TL;DR: Peninsula Approvals in 2026
- Most substantial outdoor projects trigger at least one approval: building permit, grading or drainage review, design review, tree permit, or HOA approval.
- The approval path sets the calendar: in review-heavy towns, as a planning allowance based on our experience, not a town-published timeline, start design several months before you want work to begin.
- Two ways to run it: Sequoia full-service approvals management for a fee (agency fees passed through), or client-managed with our guidance. The path is named in your contract.
- Your protection: California caps down payments on home improvement contracts at $1,000 or 10% of the contract price, whichever is less (Business and Professions Code Section 7159), excluding any separately stated finance charge.
What Triggers Approvals on the Peninsula
Approval triggers are scope-driven. The table below covers the most common outdoor-project triggers across Peninsula jurisdictions; your town’s exact thresholds control.
| Project Scope | Typical Trigger | What Reviewers Look At |
|---|---|---|
| Retaining walls | Height above the town’s exempt threshold; surcharge and slope conditions can remove exemptions; height is commonly measured from the bottom of the footing | Structural engineering, drainage behind the wall, setbacks |
| Pergolas, pavilions, outdoor rooms | Structure size, height, attachment, roofing, electrical | Setbacks, lot coverage, structural detail, sometimes design review |
| Outdoor kitchens | Gas lines, dedicated circuits, plumbing tie-ins | Licensed trade work, utility routing, clearances |
| New hardscape | Impervious-surface limits, drainage pattern changes | Stormwater management, discharge path, right-of-way at driveways |
| Grading and drainage | Cut/fill volume thresholds, altering flow toward neighbors or street | Erosion control, discharge legality, hillside conditions |
| Work near protected trees | Town tree ordinances (definitions vary, see matrix below) | Tree-protection zones during construction, arborist reports |
| Front setback / right-of-way | Driveway aprons, curb cuts, street drainage tie-ins | Encroachment permits, town standards, inspection |
Review-Heavy Towns: The Calendar Reality
Hillsborough, Woodside, and Portola Valley run architectural or site review on top of standard permits. Hillsborough’s ADRB reviews landscaping, fencing, and gates along the street, with a separate Landscape Design Review track and a water-efficiency ordinance. Woodside’s ASRB reviews site and landscape elements with a rural-character mandate. Portola Valley’s ASCC reviews site work including significant grading, larger structures, and arterial-fronting parcels. Atherton, notably, does not run a formal design-review board, but its planning rules on setbacks, landscape screening, and heritage trees are demanding in their own right and deserve the same preparation.
The practical implication is identical everywhere: submittal cycles run on the town’s calendar, not yours. A project that misses one review cycle waits for the next. Start design 2-3 months before you want shovels in the ground, and treat the review packet as a first-class deliverable: complete packages reduce avoidable delays, but approval timing and revision requirements remain outside the contractor’s control.
Heritage Trees: The Most Underestimated Constraint
Peninsula towns protect mature trees by ordinance, and protection extends beyond removal: grading, trenching, or compacting soil inside a town-defined tree-protection zone can require an arborist report and protection plan even when the tree itself is not touched. Thresholds below are from town-published sources (verified July 2026; species definitions and exclusions apply, confirm current rules with the town).
| Town | Published Protected-Tree Definition | Review Body for Outdoor Projects |
|---|---|---|
| Atherton | Heritage: specified native oaks ≥48″ circumference at 54″ anywhere on the lot; any tree that size outside the main buildable area; council-designated trees also protected; mandatory tree-protection plans and defined protection zones | Planning Department |
| Hillsborough All species at least 18 inches in diameter, measured 4 feet 6 inches above grade, per the town’s official Tree Protection Ordinance Update (verified July 2026); additional protected categories may apply, confirm current requirements before removal | ADRB / Landscape Design Review | |
| Menlo Park | Heritage: any tree ≥47.1″ circumference; native oaks ≥31.4″ | Planning / Public Works |
| Palo Alto | 2022 ordinance expansion: native oaks and added species protected at roughly 11.5″-15″ trunk diameter by species, coast redwood at 18″; amended again 2023-24, confirm current list | Planning; tree-protection sheet on plans |
| Los Altos Hills | Heritage oak: any oak ≥36″ circumference at 4 ft; site-development approvals conditioned on tree preservation | Site development review |
| Woodside / Portola Valley | Tree and site protection administered within ASRB / ASCC review scope | ASRB / ASCC |
Fire Hazard Zones and Fire-Hardening in the Hills
Much of Woodside, Portola Valley, Los Altos Hills, and the Los Gatos hills sits in state-designated Fire Hazard Severity Zones, with many properties also in the Wildland-Urban Interface. Defensible-space rules shape material and vegetation choices near structures, and fire features face siting and clearance requirements. California’s Zone 0 ember-resistant rules (noncombustible treatment within 5 feet of structures) remain under development at the state level (the Board of Forestry was still finalizing draft rule text in 2026), but CAL FIRE already recommends ember-resistant treatment near structures ahead of any final rule. If you are in the hills, tell your designer up front; it changes the plant palette and sometimes the layout.
HOA Architectural Review
Where HOAs exist, their approval is contractual, separate from, and additional to, city permits. The standard failure mode is sequencing: homeowners get city permits, then discover the HOA wants different materials or setbacks. Submit to both in parallel where the HOA’s rules and city dependencies allow it. A complete HOA packet typically includes a dimensioned site plan, materials and colors, drainage notes, and neighbor-visibility considerations. In our experience, approval windows of roughly 2-6 weeks are common for straightforward packets, though HOA governing documents control the actual maximum response period and complex reviews can run longer and some associations meet monthly.
Who Owns the Approval Process
In writing, one party should be assigned: preparing submittals, responding to plan-check comments, scheduling inspections, and managing resubmittals. At Sequoia you choose the path: full-service, where we manage the approval process end to end for a fee with agency fees passed through, or client-managed, where you run the submittals with our guidance and documentation support. Both work; what fails is ambiguity. Whichever path you pick is named in the contract, and per our guarantee terms, your guaranteed completion date is set after the Pre-Construction Walkthrough, once permits, selections, long-lead releases, and 811 are complete, so approval time is accounted for before the clock starts.
What to Demand in Writing (Approvals Edition)
- Applicant of record: who prepares, signs, and files each submittal, and which are included or excluded.
- Agency fees: who pays them and how they are billed.
- Resubmittals: cost and schedule impact when a reviewer asks for changes.
- Inspections: which are anticipated and who meets the inspector.
- The completion date: how it accounts for approval timelines.
Your protections under California law: on home improvement contracts, down payments are capped at $1,000 or 10% of the contract price, whichever is less, excluding any separately stated finance charge, and progress payments must track work and qualifying materials actually delivered. Verify any contractor’s license and bond on the CSLB public lookup. Sequoia operates under CA License #1099847; a Class A General Engineering classification, which covers the structural retaining, grading, and drainage work many of our projects require; other trades may need a separate license or a civil/structural engineer for the same scope.
Frequently Asked Questions
Do I need a permit for a paver patio?
Some at-grade replacements may not require a building permit, but planning, drainage, tree, HOA, design-review, or right-of-way approvals may still apply, and impervious-surface limits or grading thresholds can catch large or hillside projects. We verify against your town’s current rules during design.
How much time does design review add in towns like Hillsborough or Woodside?
Based on our experience, allow for at least one review cycle on top of standard permit timelines, with possible resubmittals. Complete packages that anticipate the town’s known sensitivities are more likely to pass without a resubmittal, though this is our experience, not a town guarantee.
Can work start while permits are pending? Do not begin work that requires a permit until that permit has been issued. Separate permit-exempt work may sometimes proceed if the jurisdiction and your contract allow it. Unpermitted work risks stop-work orders, fines, redone work, and disclosure problems at resale.
Who pulls the permits, you or me?
Your choice, stated in the contract: Sequoia full-service (we manage the process for a fee, agency fees passed through) or client-managed with our guidance. Most clients choose full-service; either way ownership is explicit and the schedule accounts for it.
What if my project is in an HOA and a review-heavy town?
Both processes run, ideally in parallel. We map both at design time so the guaranteed completion date reflects reality.
Plan the approvals before you fall in love with the design
Request a Project-Fit Consultation for a preliminary discussion of the likely approval layers on your property: town, overlays, trees, HOA. Final requirements and timing depend on property research and agency confirmation.
