Unlicensed professionals may design a number of structures that are typically limited in height, size, or construction type (i.e. wood frame), with structural and/or seismic limitations. It is worth making a visit to the local building permit office to inform them of your plans and get their feedback. In deciding if you need a licensed architect, the building official will consider existing state laws, public health, safety, and welfare, local environmental and geographical conditions such as snow loads, winds, earthquake activity, tidal action, and soil conditions. Refer to your local jurisdiction for full details, but the following are common allowable structures:
• Two storey (+ basement), wood-frame single family dwellings;
• Two storey (+ basement), wood-frame fourplex;
• Two storey (+ basement), wood-frame garages or other structures appurtenant to buildings
• Wood-frame agricultural and ranch buildings, unless the Building Official deems undue risk.
• Non-structural or non-seismic store fronts, interior alterations or additions, fixtures, cabinet work, furniture, or other appliances or equipment and their installation.
