A Custom Outdoor Patio Designed and Built Under One Contract
Permit requirements confirmed before design begins — attached structures and freestanding elements treated correctly from the start. Hardscape, cover structure, and outdoor electrical under one point of accountability.
Permit Path First
Custom Outdoor Patio Construction — What Determines the Permit Path
The permit path for your patio is determined by one question: does the structure touch your house?
Custom patio construction covers a wide range: hardscape (concrete, pavers, decomposed granite, or natural stone) forms the base; an attached patio cover connects to your home’s wall or eave; a freestanding pergola stands on its own posts. Those last two look similar from the backyard — but they sit in completely different regulatory categories.
An attached cover transfers structural loads to your home’s framing, which triggers a building permit every time. A freestanding pergola may or may not, depending on height and square footage. We determine that classification for your specific project before design starts — so the design is built around what can actually be permitted.
Two Structures, Two Rulebooks
Attached or Freestanding — the Distinction That Determines Everything
They look similar from the backyard. They sit in completely different regulatory categories — and which one you’re building is the first thing we confirm.
Attached Patio Cover
A roof or overhead structure connected to your home’s wall or eave. It transfers load to your framing — which triggers a building permit every time, no exceptions, and sometimes reinforcement of the existing framing at the attachment point.
Freestanding Pergola
Stands entirely on its own posts with no connection to the home. Height and square footage determine whether a permit is required at all — structures under 120 sq ft and below 8 ft may qualify for an exemption in some jurisdictions.
Local Knowledge
Patio & Cover Structure Builds Across the Lamorinda Corridor
The Lamorinda corridor is home to larger residential lots where covered patios and hardscape are common additions — many built between the 1950s and 1980s, with eave heights and framing that reflect that era.
- 1950s–80s residential stock — eave heights, exterior wall framing, and existing panels reflect that era across Lafayette, Orinda, Moraga & Walnut Creek.
- The attachment point matters as much as the structure — older roof framing may need reinforcement before it can carry a new cover's dead load, assessed before a design is drawn.
- We know how the county reviews attached-structure applications — built patio and cover structures throughout the Lamorinda area for decades.
The Deciding Question
The structural connection to your home is the single decision that determines the permit pathway.
I’m Shay Zilber. A homeowner usually starts with what they want — a covered area off the back, some pavers, maybe a fan and a couple of lights — and the conversation begins around what it looks like before anyone has asked what it connects to. But the structural connection is what determines everything.
An attached patio cover, even a small and simple one, is structurally connected to the existing home. The load has to be calculated, and the permit application must show how it transfers to the home’s framing — sometimes the framing needs reinforcement. A freestanding pergola on its own posts is a different calculation, where square footage and height decide whether a permit is required at all. We classify this correctly at the start of every project, and the design process begins after the permit question is answered. That’s not a complication — it’s the right sequence.

One Contract
How We Design and Build Custom Outdoor Patio Spaces Under One Contract
One contract covers every element — hardscape base, cover structure, and outdoor electrical. Our standards on outdoor patio projects:
- Permit classification first — attached or freestanding, determined before any design work begins.
- Hardscape drainage built in — a minimum 1/8 inch-per-foot slope in every concrete or paver install, moving water away from your foundation.
- Structural load assessed for attached covers — cover load calculations happen before framing, not during permit review.
- Outdoor electrical done correctly — weatherproof outlets, lighting & fan wiring under a separate electrical permit with weatherproof-rated components, coordinated alongside the structural permit.
- Materials specified for your fire zone — ignition-resistant decking & framing for Moderate/High/Very High zones, checked before specifying a single product.
- Design-build delivery — one team, one contract, one point of accountability from first drawing to final inspection.
Classify, Build, Inspect
Hardscape, Cover Structure & Electrical Integration — Our Patio Build Sequence
Every patio project follows the same sequence: classify, design, permit, build, inspect.
- Diagnostics — permit classification (attached vs. freestanding), fire-zone designation, panel capacity & drainage flow answered before any design resource is committed; for attached covers, eave height & wall framing assessed at the attachment point.
- Implementation — hardscape first (grading, base, surface with drainage slope built in), then the cover structure (posts, beams, roofing, attachment hardware), then outdoor electrical roughed in before enclosure so wiring stays accessible for inspection.
- Post-service testing — separate final inspections for the structural and electrical permits, both coordinated; the project isn't complete until every open permit has a signed inspection card.
Service Coverage
Outdoor Patio Projects Across Lafayette & the East Bay
We build custom outdoor patio spaces across Lafayette, Orinda, Moraga, Walnut Creek, Pleasant Hill, and the broader Contra Costa County region — from covered patio construction to hardscape, the process starts the same way: permit classification before design.
Describe Your Outdoor Space — We'll Map the Permit Path
Describe the space: approximate size, whether you’re considering an attached cover or a freestanding structure, and your property address. We’ll identify your fire-zone designation, confirm the permit pathway, and schedule a site visit to assess attachment points, drainage, and electrical capacity.

Good to Know
Outdoor Patio Questions Before the Design-Build Process Begins
Yes. Any patio cover structurally attached to your home triggers a building permit under California building code because it transfers load to the home’s framing. There are no square-footage thresholds that create an exemption for attached structures in Contra Costa County. Freestanding pergolas follow different rules and may qualify for an exemption depending on height and size.
The structural connection determines permit classification. An attached patio cover connects to your home’s wall or eave and requires a structural permit. A freestanding pergola stands entirely on its own posts; freestanding structures under 120 sq ft and below 8 ft may qualify for a permit exemption in some jurisdictions — but that determination is made on a project-by-project basis after reviewing your specific property.
Yes. Properties in Moderate, High, or Very High Fire Hazard Severity Zones — which apply to a significant portion of Lafayette’s hillside and woodland-edge areas — require ignition-resistant materials under California Building Code Chapter 7A, including decking, framing, and overhead roofing on covered structures. We confirm your CAL FIRE designation before specifying any product.
It varies by complexity. A straightforward attached patio cover with complete documentation typically moves through plan check in four to eight weeks. Projects requiring engineered structural drawings — particularly attachment to older or reinforced framing — may take longer. We submit complete packages the first time to avoid correction-letter delays.
No. Outdoor electrical integration — weatherproof outlets, overhead lighting, ceiling-fan rough-in — requires a separate electrical permit. The structural permit covers the hardscape and cover structure; the electrical permit covers all wiring and fixtures. Both require their own final inspections before the project closes. We coordinate both applications and both inspections under the same contract.
We assess the home’s eave height and wall framing at the proposed attachment point before design begins. If the existing framing requires reinforcement to accept the cover’s dead load, that scope is identified and priced before a design is drawn — not discovered mid-permit or mid-build. Framing reinforcement, when required, is incorporated into the project scope and permit package from the start.
