Title XVII

Chapter 17.98

Windsor Zoning Code · 2026-06 edition · ingested 2026-07-07 · Windsor

17.98.010 Purpose and Intent.

The Town of Windsor recognizes the importance of achieving a diverse and balanced community with housing available for households of all income levels. Economic and social diversity cultivates a healthy social fabric that is beneficial to all residents of Windsor. The Town is experiencing an increasing shortage of housing affordable to very low-, low-, and moderate- income households. New residential development does not provide housing opportunities for this segment of society. As a result, very low-, low-, and moderateincome households are excluded from new housing, creating economic stratification in the Town that is detrimental to the public health, safety, and welfare.

The purpose of this chapter is to establish an inclusionary requirement on residential development projects. This chapter will mitigate the impacts caused by these development projects for the additional demand for more affordable housing and rising land prices for limited supply of available residential land. The inclusionary requirements required by this chapter do not replace other regulatory requirements and processing fees or exactions, funding required pursuant to a development agreement or reimbursement agreement; assessment charged pursuant to special as-
