Plan Check
This is the public face of the Building and Grading Plan Check sections. Counter staff will answer questions regarding plans, regulations and the permit process, take in plans for plan check, review plans for completeness, assign valuations and fees, and issue permits after clients have paid the cashier. Staff may also check simple plans over the counter such as those utilizing standard plans (some retaining walls, swimming pools, patio covers, signs, solar panels) and simple additions and new structures (re-roofs, some room additions, trellises, etc). Permits may be extended here if warranted. Staff checks and issues permits for private sewer and waste systems as well as scheduling percolation tests. The Grading Plan Check section reviews grading plans and soil engineering and/or engineering geology reports submitted for proposed grading projects located within the unincorporated portions of Orange County.
