Real estate investors
Review published code-enforcement records with property context where linkage is available. A violation is a research signal, not evidence that an owner intends to sell.

An addition or remodel can be useful project context for HVAC, plumbing, or warranty outreach. Review the project signal before outreach.
Solar installers
Roof permits and electrical upgrades in Montgomery County provide project context for solar-market research. Filter by the current project signal and verify ownership separately.

Montgomery County renovations can identify properties for a policy-review workflow. Confirm coverage needs independently before contacting a property owner.
