Building Permits Rise 5.8% in April, Higher Than Expected

Background on Building Permits

Building permits track the government issuance of permits that are typically required for builders to begin construction on a new home. The data on building permits give a sense of how much and where future construction activity will take place and thus are an excellent marker of future home building. A critical aspect of the home-building industry is the powerful influence it has on the rest of the economy. The data is divided into three types of structures: single-family homes, residences with 2-4 units (condos or townhouses), and structures with 5+ units (apartment complexes).

Here is the complete historical series, which dates from 1960. Because of the extreme volatility of the monthly data points, a six-month moving average has been included.

Building Permits: Structure Breakdown

In April, single-family building permits were at a seasonally adjusted annual rate of 0.872 million. This represents a 2.6% decrease from March and a 5.5% decline from the previous year.

Residences with 2-4 units building permits were at a seasonally adjusted annual rate of 0.056 million in April. This represents a 14.3% increase from March and an 8.2% decline from the previous year.

Lastly, multi-family buildings building permits were at a seasonally adjusted annual rate of 0.514 million in April. This represents a 22.7% increase from March and an 11.5% rise from the previous year.

Building Permits: The Population-Adjusted Reality

Here is the data with a simple population adjustment. The Census Bureau's mid-month population estimates show substantial growth in the US population since 1960. Here is a chart of housing starts as a percent of the population. We've added a linear regression through the monthly data to highlight the trend.

Building Permits: A Footnote on Volatility

The extreme volatility of this monthly indicator is the rationale for paying more attention to its six-month moving average than to its noisy monthly change. Over the complete data series, the absolute month-over-month average percent change was 4.4%. The month-over-month range minimum was -24.0% and the maximum was 33.9%.

For visual confirmation of the volatility, here is a snapshot of the monthly percent change since 1960.

A Long-Term Look: Residential Building Permits and Housing Starts

In addition to building permits, the U.S. Census Bureau and the Department of Housing and Urban Development published their findings for new residential housing starts. Housing starts are the actual construction projects that have begun and typically follow building permits. Despite the fact that both are monthly seasonally adjusted annualized rate (SAAR) series, they are exceptionally volatile and subject to extensive revisions. Thus it is unwise to assign much significance to a single month.

Over the long haul, however, the two offer a compelling study of trends in residential real estate, especially when we adjust the permits and starts for population growth. Here is an overlay of the two series since the 1959 inception of the starts data and the 1960 inception of the permits data. The monthly data points are preserved as faint dots. The trends are illustrated with six-month moving averages of data divided by the Census Bureau's mid-month population estimates.

Here is a closer look at the overlay since 1990.
