I do think too there should be always quality standards for construction to secure a minimum quality of housing (Most of what attracts people to suburbia besides the price is privacy). But I think the biggest inflater usually is height-restrictions, parking-lot-requirements and a general uncertainty of what an ownership title actually means: in every municipality you'll find different possibilities of NIMBY-interference and likelihoods thereof.
