Lakewood’s new housing cap law could constrict the number of residential permits available to developers this year to a mere 156 new units across this city of 155,000, if a plan set to go before city leaders later this month is adopted. That’s because even though the city’s new growth control measure, which allows an increase in residential construction of no more than 1% of Lakewood’s existing housing stock, should theoretically make room for 693 new homes in 2020, the city is proposing to take residential projects already in the approvals process and offset them against the new limit this year and next. That means counting the 1,075 housing units that are currently at some stage of review with Lakewood planning officials toward the annual cap in both 2020 and 2021.
