KBP OS · ADU + General Construction

From the first lead to a managed construction process.

KBP OS is a lead-generation and process-management platform for ADU and general construction—residential and commercial. We’re open to GC projects beyond ADUs.

Plan and material studies on a wood workbench in daylight: an architectural floor plan drawing, material sample tiles, a graphite pencil, and a metal ruler.

How the product stays legible

Three planes, each with a different job.

The surface separates model choice, property context, and human review so a concept does not become a conclusion simply because it is visible.

  1. 01

    Model choice

    Compare the owned concept records and their published maturity boundaries.

    Does not determine a property fit.

  2. 02

    Property context

    Use jurisdiction records and official sources to orient the next question.

    Does not determine eligibility or buildability.

  3. 03

    Human review

    Keep unknowns and cross-discipline questions visible before a decision advances.

    Does not automate approval or commitment.

Owned model preview

The current release contains exactly three concept families.

Each card is a projection of the validated owned-model release. The cards do not introduce a separate product taxonomy or program facts.

Concept Studio

Explore anonymously, before a property is in view.

Concept Studio is property-agnostic and collects no address or contact information. Model-bound migration from release 2026.09.0 is in development; it is not active today.

Service paths

Name the path, then open the right context.

The four published service paths open their own existing pages. Residential Addition remains intentionally unresolved until its dedicated route is published.

Process

Orient, explore, review context, then make a human decision.

The order keeps early exploration useful without treating a model or a jurisdiction context as a promise about a project.

  1. 01

    Orient

    State the desired direction without treating missing facts as answers.
  2. 02

    Explore

    Inspect a concept family or anonymous Studio scenario.
  3. 03

    Review context

    Use current official sources and appropriate review for the next question.
  4. 04

    Human decision

    Decide whether a bounded next step is appropriate, paused, or declined.

Service-area context

City and County context stay separate.

Select an existing official-source guide for the City of Sacramento or unincorporated Sacramento County. Neither guide decides a parcel fit.

01

City of Sacramento

This page does not determine jurisdiction, zoning, permit status, feasibility, or buildability for a property. Requires official source verification.

Truth boundary

Keep facts, concepts, and unknowns visibly apart.

The distinction is deliberate: a visitor can see which statements are owned product facts, which media is conceptual, and which questions remain gated.

  • Verified product facts

    Release-bound model IDs, versions, program, envelope, maturity, and provenance.

  • Conceptual media

    Every image is labeled beside the image and is not presented as a completed project.

  • Unknown / professional gates

    Property, approval, and construction questions remain outside an editorial card.
