A Tigard solar or electrical-upgrade scope should begin with the existing service, documented loads, roof or mounting condition and intended outcome. Building approval, utility interconnection and licensed electrical work are separate responsibilities, so the proposal should name each boundary rather than promise a generic panel count.
Require existing-service evidence, load and production assumptions, a named equipment schedule, roof and pathway details, permit and utility responsibilities, shutdown planning, commissioning and closeout records.
Document service and panel ratings, available spaces, grounding and bonding, meter location, major loads, prior alterations and observed damage. Separate safety correction from capacity added for the proposed system.
Identify bill offset, new vehicle or heat-pump loads, backup needs, expected operating pattern and the consumption records used. A projection should disclose its inputs rather than function as a guarantee.
Record roof material, condition, drainage, penetrations, attachment layout and responsibility for weather sealing. Assign any structural review and future removal or reinstallation boundary.
Tigard Building Services publishes permit and inspection resources. Confirm the address and whether electrical, structural or energy work changes the submitted package.
Identify the serving utility from the account, then assign application, studies, meter work, communications and permission-to-operate responsibility. A passed city inspection is not utility authorization.
List modules, inverter, battery, racking, disconnects, rapid-shutdown components, monitoring, required service equipment, controls and warranties by model or documented performance level.
State shutdown duration, utility coordination, essential-load needs, weather limitations and occupant communication. Do not improvise temporary power outside the approved plan.
Verify labels, torque or connection records where required, grounding, protective functions, shutdown, monitoring, backup modes and owner instruction against the approved design.
Keep approved plans, permits, inspection records, utility permission, equipment serials, photographs, monitoring access, warranty information and emergency shutdown instructions.
Describe your project once and we help connect your request with relevant local contractors who serve your area. The request is free, there is no obligation to hire, and you decide whether anyone is right for the job.
Confirm the parcel before assigning City of Tigard applications, review or inspections.
Oregon CCB provides public tools for checking the legal contractor business.
Electrical, plumbing and other regulated work must be assigned to appropriately licensed businesses.
| Decision | Proposal must state | Acceptance evidence |
|---|---|---|
| Existing service | Ratings, grounding, spaces and loads | Photos and measured design basis |
| Solar array | Layout, attachments and pathways | Approved plan and model schedule |
| Storage or backup | Protected loads and operating mode | Demonstrated transfer and controls |
| Approvals | City and utility responsibilities | Final inspection and utility permission |
| Restoration | Roof, siding and finish repairs | Weather-tight completed surfaces |
Separate investigation, design, applications, regulated trades, products, access, protection, removal, restoration, testing and closeout. Reconcile allowances and exclusions before comparing totals; generic unit prices cannot represent the observed property condition.
Approval depends on the property and complete scope. Confirm the address with the identified local building authority before assigning applications or inspections.
Search the exact legal business through Oregon CCB and verify any regulated trade business through the applicable state records.
Yes. Share the same photos, measurements, goals, product expectations and known conditions so differences in scope remain visible.
Set a written stop point requiring evidence, options, price, schedule effect and approval before expanded work begins.
Name the category, quantity basis, included delivery and installation, selection deadline, markup treatment and substitution process.
Assign patching, paint, trim, siding, roofing, flooring and cleanup explicitly instead of assuming another trade will finish them.
Use required approvals, operation checks, photographs, product records, warranties, punch-list resolution and a clean handoff.
Not until quantities, products, exclusions, permits, trade boundaries, restoration and closeout describe the same finished result.
Share the address, goals, photos, measurements and known conditions so contractors can price the same finished result.
