ContractorDave Intelligence

Know the Property Before You Design, Buy or Build.

Desktop research and boots-on-the-ground SiteWalk services reveal zoning, setbacks, access, utilities, grading, fire constraints and agency requirements before expensive commitments are made.

Universal Positioning

Homes & ADUs We Research

The property and local jurisdiction determine what can be built—not the product label or construction method.

ADUs of Every Type

HUD & Factory-Built Homes

Tiny Homes & Park Models

Attached and detached ADUs, garage conversions and JADUs evaluated for zoning, setbacks, access, utilities and site constraints.

Modular homes, factory-built structures, and HUD-code manufactured housing reviewed against local municipal installation rules.

Moveable tiny homes and park model RVs assessed for physical constructability and access where locally allowed by jurisdiction.
