CONSTRUCTION & DEVELOPMENT

Construction Development

Development runs smoother when scope, permits, and construction move as one.

OnePhase Inc provides construction development services in San Diego, supporting residential homes, ADUs, commercial projects, and renovations from early feasibility through build-ready execution. We start by evaluating site constraints, zoning realities, and project goals to define a clear development strategy—so scope, budget, and timeline are grounded in what can actually be approved and built.

Our process aligns planning, documentation, and coordination across the full pre-construction pipeline. That includes program definition, cost modeling, value-driven options, entitlement and permitting support, and consultant alignment (architectural, structural, and MEP as applicable). By resolving critical decisions early and keeping documentation consistent, we reduce plan-check friction and protect the construction schedule.

01
Roadmap

We define the end-to-end path from feasibility to delivery—site evaluation, entitlement strategy, design milestones, permitting timelines, procurement windows, and construction phases.

02
Scope + Program

We translate goals into a clear program—square footage targets, unit mix (if applicable), layout priorities, performance requirements, and finish level—while documenting inclusions/exclusions.

03
Budget & Pro Forma

We build a realistic cost framework early—hard costs, soft costs, contingencies, and schedule impacts—so the financial model supports the development strategy. By validating assumptions with market pricing.

04
Permitting Strategy

We identify the approvals required and organize the documentation to support them—permit-ready plan sets, exhibits, narratives, and coordination with consultants and agencies.

Delivery & Stakeholder

  • We coordinate the moving parts—architects, engineers, city reviewers, utilities, contractors, and vendors—using structured reporting, decision logs, and change control. This keeps accountability clear, reduces miscommunication, and supports a smoother transition from approvals into construction execution and closeout.
