In Beverly Hills, virtually any structural alteration, interior or exterior improvement, general repair, new construction or demolition requires a building permit . The City has adopted an Online Plan Review and Permit Application (OPA) portal for new electronic plan review applications . Applicants must submit plans through OPA, after which staff review the submittal, assign a reference number and estimate review time . Once review fees are paid, applicants receive instructions for submitting plan revisions through the portal; modifications to issued permits are handled outside OPA . This process, combined with Beverly Hills’ own municipal code, design review requirements and Title 24 energy standards, can create long feedback loops when plans are incomplete or uncoordinated.

AI‑powered engineering for Beverly Hills homes

Spacial keeps Beverly Hills projects on track with AI‑generated structural, MEP and energy plans that are ready for OPA submission. We convert your 2D drawings into a 3D model, check them against California building codes and Beverly Hills’ municipal code, and coordinate structure, MEP and energy requirements. Our engineers refine and stamp the final set. We package your plans for the OPA workflow and break down the steps into initial application, staff review, fee payment and revisions so you can move from submittal to permit approval with fewer cycles. The result is a streamlined, predictable path from design to permit.

A simple three‑step process for Beverly Hills homes

Step 1: Plan. Upload your architectural plans to our portal. Our system analyses the layout, structure and mechanicals against Beverly Hills’ building code, Title 24 energy requirements and any local design review guidelines. We prepare your submission documents for the OPA’s initial submittal phase and ensure all required components are included.

Step 2: Convert and validate. Our AI produces an object‑based 3D model. Structural and MEP agents collaborate to size members, coordinate ductwork and integrate plumbing and electrical. We conduct energy modeling to meet Title 24 standards. Licensed engineers review and refine the model so that it aligns with Beverly Hills’ municipal code and OPA expectations.

Step 3: Approve. You receive a complete, stamped set of plans ready to upload via OPA. Because our deliverables are organised for the four‑step OPA process, which includes application submittal, staff review, fee payment and plan revisions, you can navigate the portal efficiently and reduce resubmittals .

Structural, MEP and energy under one roof for Beverly Hills

Structural engineering is the backbone of the permit set. We design foundations and frames to meet California building code requirements while accommodating Beverly Hills’ architectural styles, ranging from historic mansions to modern estates. MEP engineering happens alongside structure. We produce HVAC layouts that maximise comfort without compromising aesthetics, electrical designs that account for luxury appliances and smart home systems, and plumbing plans that fit the structural scheme. Energy modeling is integrated from the beginning to meet Title 24 efficiency requirements. By coordinating these disciplines, we avoid conflicts that can delay OPA review.

ADU permit expediting in Beverly Hills

ADUs and accessory structures must still comply with Beverly Hills’ stringent building and zoning codes. Our team prepares structural, MEP and energy packages for ADUs that conform to the OPA’s requirements. By submitting coordinated and code‑compliant plans, we help expedite the review process and minimise revisions.

Why Spacial is a fit for Beverly Hills

• We understand the OPA workflow. Our submittal packages align with the city’s four‑step process: application, staff review with reference number assignment, fee payment and plan revisions .

• We know Beverly Hills’ code requirements. Our platform integrates California building code, Beverly Hills’ municipal code and Title 24 energy standards so your plans meet all applicable requirements.

• We respect Beverly Hills architecture. Whether you’re working on a mid‑century home or a contemporary hillside estate, we engineer solutions that support the design rather than fight it.

• We are builder‑led. Our leadership comes from construction and development, so we emphasise constructibility and clear details that reduce field confusion and inspector pushback.

Common questions about building in Beverly Hills

What is Beverly Hills’ Online Plan Review and Permit Application (OPA)? The OPA is the city’s portal for new electronic plan‑review applications. It is used for building permits for structural alterations, interior or exterior improvements, general repairs, new construction and demolition. Applicants submit their plans, staff assign a reference number and estimate review time, fees are paid, and plan revisions are submitted through the portal.

What projects require a building permit in Beverly Hills? Any structural change, improvement, repair, new construction or demolition requires a permit. The city’s municipal code outlines the specific requirements, and permits must be obtained through the OPA. We provide engineering sets that meet these requirements.

Do you need a structural engineer for an ADU or remodel in Beverly Hills? Yes. New construction and most remodels require a licensed structural engineer to design and stamp the plans. We deliver structural, MEP and energy packages that satisfy Beverly Hills’ permitting standards.
