Building permits are generally required for most types of construction. The Building Code states no building or structure regulated by this code shall be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished unless a separate permit for each building or structure has first been obtained from the building official.
Some work, however, may be done without a permit:
Retaining walls or planters four feet or less (from the bottom of the footing), decks less than thirty inches high, above ground pools five thousand gallons or less and no more than 24" in depth, window coverings, one-story detached accessory structures used as tool and storage sheds, playhouse, and similar uses, provided the floor area is not greater than 120-square feet (must comply with zoning setbacks), painting and wallpapering, floor coverings, cabinet replacement, low voltage lighting, fixture or outlet replacement, moveable cases, counters and partitions under five feet are a few examples.
A permit may be obtained by the property owner, a licensed contractor, or a certified agent of the property owner. Some permits may be issued over the counter, for small projects such as re-roofing or an HVAC replacement, but larger projects will need to have plans submitted and have the plans checked which can take from two to six weeks.
Check with the Planning Department for the zoning requirements.
Any alteration of the commercial building will also need to go to design review.
Permit fees are based on the valuation of the project and the number of plumbing, mechanical, and electrical systems. The building and plan check fee will be collected at the time the plans and documents for the structure are submitted for plan check. The permit fees will be collected at the time the permit is issued.
