Re: Code Enforcement Complaint – Suspected Unpermitted Construction at 2514 Reata Pl, Diamond Bar, CA 91765
To the Neighborhood Improvement Division:
I am submitting this letter as a formal code enforcement complaint regarding construction activity at 2514 Reata Pl, Diamond Bar, CA 91765. I am the owner of the adjacent property at
2510 Reata Pl, Diamond Bar, CA 91765.
As shown in the enclosed photographs, taken from my property, the work at 2514 Reata Pl includes removal of exterior wall sheathing over a substantial portion of the structure, an apparent
new second-story window opening facing directly into my backyard and pool area, and visible modification to the roofline. I have not observed any posted permit card or public notice
at the site, and I have no information confirming that this work is authorized by a valid building permit or planning entitlement.
I am requesting that the Neighborhood Improvement Division:
1. Investigate whether the work currently underway at 2514 Reata Pl is covered by a valid, active building permit and, if applicable, planning entitlement, consistent with the scope
of work shown in the enclosed photographs.
2. If no such permit or entitlement is on file, or if the work exceeds the scope of any permit issued, take appropriate enforcement action, which may include a stop-work order and requiring
the property owner to submit complete plans for review.
3. Advise me of the case or complaint number assigned to this matter, and the expected timeline for an initial site inspection.
I understand that this complaint may be handled confidentially with respect to my identity as the complainant, to the extent permitted by the City's standard practice, and I would appreciate
confirmation of how the City handles complainant information in code enforcement matters.
I am also submitting a related, more detailed inquiry to the Planning Division under separate cover, which includes a formal Public Records Act request concerning permits, entitlements,
and notification records for this same property. This complaint may be treated as a companion to that inquiry, or processed independently, whichever is more appropriate for your department's
procedures.
Please contact me by phone or email with any questions, or to arrange a site visit. Thank you for your prompt attention to this matter.
Sincerely,
David Xu
