20.30.010 Purposes of chapter and Endings.¶
In order to provide for the housing needs of all economic segments of the community, the city council declares
that the purposes of this chapter are as follows:
A. To insure a reasonable balance of rental and ownership housing in Petaluma and a variety of individual
choices of tenure; type; price and location of housing;
B. To maintain the supply of rental and mobile home housing opportunities for low and moderate-income
persons and families; and
C. To reduce and avoid the displacement of long-term residents; particularly senior citizens and families with
school age children; who may be required to move from the community due to a shortage of replacement rental
and mobile home housing opportunities.
The city council Jnds and declares that when the number of vacancies being oMered for rent or lease in the city is
equal to or less than three percent of the total number of such dwelling units oMered for and under rental or lease
agreement in the city; a housing shortage exists which is inconsistent with the purposes of this chapter and with
the declared goals and objectives of the city relating to its housing element of its general plan.
The council further Jnds that the conversion of existing apartment buildings or mobile home parks into
community housing diminishes the supply of rental and mobile home housing opportunities and displaces
residents and will tend to require them to move outside of Petaluma when a housing shortage exists.
(Ord. 1519 NCS §1, 1982; Ord. 1341 NCS §1, 1978.)
